I. Executive Summary and Background

A. Executive Summary

1. Purpose and Legal Authority
    Since 1984, Medicare has paid for clinical diagnostic laboratory 
tests (CDLTs) on the Clinical Laboratory Fee Schedule (CLFS) under 
section 1833(h) of the Social Security Act (the Act). Section 216(a) of 
the Protecting Access to Medicare Act of 2014 (PAMA) (Pub. L. 113-93, 
enacted on April 1, 2014) added section 1834A to the Act. This statute 
requires extensive revisions to the Medicare payment, coding, and 
coverage requirements for CDLTs. In this proposed rule, we present our 
specific proposals for implementing the requirements of section 1834A 
of the Act.
2. Summary of the Major Provisions of This Proposed Rule
    Section 1834A of the Act significantly changes how CMS will set 
Medicare payment rates for CDLTs, which are paid for on the CLFS. 
Applicable laboratories will be required to report to CMS certain 
information about the payment rates paid by private payors for each 
CDLT and the corresponding volumes of such tests furnished during a 
period of time specified by the Secretary of the Department of Health 
and Human Services (the Secretary). In general, with certain designated 
exceptions, the statute requires that the payment amount for CDLTs 
furnished on or after January 1, 2017, be equal to the weighted median 
of private payor rates determined for the test, based on certain data 
reported by laboratories during a specified data collection period. 
Different reporting and payment requirements will apply to a subset of 
CDLTs that are determined to be advanced diagnostic laboratory tests 
(ADLTs). The most significant proposed policies in this proposed rule 
include the following (more detailed descriptions follow the bulleted 
list):
     The definition of ``applicable laboratory'' (the entities 
that must report applicable information).
     The definition of ``applicable information'' (the specific 
data that must be reported).
     The definition of an ADLT.
     Data collection and data reporting.
     The schedule for reporting applicable information to CMS.
     Data integrity.
     Confidentiality and public release of limited data.
     Coding for certain CDLTs.
     The payment methodology for CDLTs.
     The local coverage determination (LCD) process and the 
designation of Medicare Administrative Contractors (MACs) for 
laboratory tests.
    Under the authority of section 1834A(a)(2) of the Act, in section 
II.A of this proposed rule, we are proposing to define an ``applicable 
laboratory'' as a laboratory that receives more than 50 percent of its 
Medicare revenues from 42 CFR part 414, subparts G and B (that is, for 
services that are paid by Medicare under the CLFS and the Physician Fee 
Schedule (PFS)) in a data collection period. We also propose that if a 
laboratory receives less than $50,000 in Medicare revenues in a data 
collection period from 42 CFR part 414, subpart G (that is, for 
services that are paid by Medicare on the CLFS), it would be excluded 
from the definition of an applicable laboratory. In addition, we are 
proposing to define applicable laboratories at the Taxpayer 
Identification Number (TIN) level rather than the National Provider 
Identifier (NPI) level.
    The statute requires an applicable laboratory to report the 
following applicable information for each test on the CLFS it performs: 
(1) The payment rate that was paid by each private payor for each test 
during the data collection period; and (2) the volume of such tests for 
each such payor. As discussed in section II.B., we propose to use the 
term ``private payor rate'' in the context of applicable information, 
instead of ``payment rate,'' in order to minimize confusion because we 
typically use the term payment rate to generically refer to the amount 
paid under the CLFS. We propose that the private payor rate reflects 
the price for a test prior to application of any patient deductible and 
coinsurance amounts. We are also proposing that only applicable 
laboratories may report applicable information.
    Section 1834A(d)(5) of the Act specifies criteria for defining an 
ADLT (discussed in section II.C.) and authorizes the Secretary to 
establish additional criteria. At this time, we are only proposing to 
apply the criteria specified in statute and are not proposing any 
additional criteria under the statutory authority conferred upon the 
Secretary.
    In section II.D. of this proposed rule, for the initial data 
collection period, we propose that applicable laboratories must report 
applicable information to CMS for the period of July 1, 2015, through 
December 31, 2015. All subsequent data collection periods would cover a 
full calendar year (CY). Further, we are proposing that all applicable 
information, except for new ADLTs, would be due to CMS by March 31 of 
the year following the data collection period. We also propose that the 
applicable information for new ADLTs must be reported to CMS by the end 
of the second quarter of the new ADLT initial period.
    We propose to apply a civil monetary penalty (CMP) to an applicable 
laboratory that fails to report or that makes a misrepresentation or 
omission in reporting applicable information (described in section 
II.E.). We propose to require all data to be certified by the 
President, Chief Executive Officer (CEO), or Chief Financial Officer 
(CFO) of a laboratory before it is submitted to CMS. As required by 
section 1834A(a)(10) of the Act, certain information disclosed by a 
laboratory under section 1834A(a) of the Act is confidential and may 
not be disclosed by the Secretary or a Medicare contractor in a form 
that reveals the identity of a specific payor or laboratory, or prices, 
charges or payments made to any such laboratory,

[[Page 59388]]

with several exceptions (described in section II.F.).
    We propose to use G codes, which are part of the Healthcare Common 
Procedure Coding System (HCPCS) coding system CMS uses for programmatic 
purposes, to temporarily identify new ADLTs and new laboratory tests 
that are cleared or approved by the Food and Drug Administration (FDA). 
The temporary codes would be in effect for up to 2 years until a 
permanent HCPCS code is established except if the Secretary determines 
it is appropriate to extend the use of the temporary code.
    As required by section 1834A(b) of the Act, payment amounts for 
laboratory tests on the CLFS will be determined by calculating a 
weighted median of private payor rates using reported private payor 
rates and associated volume (number of tests). For tests that were paid 
on the CLFS prior to the implementation of section 1834A of the Act, 
PAMA requires that any reduction in payment amount be phased in over 
the first 6 years of payment under the new system. For new ADLTs, 
initial payment will be based on the actual list charge of the test for 
3 calendar quarters; thereafter, the payment rate will be determined 
using the weighted median of private payor rates and associated volume 
(number of tests) reported every year. For new and existing tests for 
which we receive no applicable information to calculate a weighted 
median, we propose that payment rates be determined by using 
crosswalking or gapfilling methods. These methods of determining 
payment are discussed in section II.H. of this proposed rule.
    Section 1834A(g)(2) of the Act authorizes the Secretary to 
designate one or more (not to exceed four) MACs to establish coverage 
policies, or establish coverage policies and process claims, for CDLTs. 
As noted in section II.I. of this proposed rule, we are requesting 
public comment on the benefits and disadvantages of implementing this 
discretionary authority before making proposals on this topic. We are 
therefore making no proposals with regard to this topic at this time.
3. Summary of Costs and Benefits
    In section V. of this proposed rule, we provide a regulatory impact 
analysis that, to the best of our ability, describes the expected 
impact of the proposals described in this proposed rule. The proposed 
policies, which would implement new section 1834A of the Act, include a 
process for collecting applicable information from applicable 
laboratories on the rates that are paid by private payors for CDLTs and 
their associated volume. We note that, because such data are not yet 
available, we are limited in our ability to provide estimated impacts 
of the proposed payment policies under different scenarios.

B. Background

1. The Medicare Clinical Laboratory Fee Schedule (CLFS)
    Currently, under sections 1832, 1833(a), (b), and (h), and 1861 of 
the Act, CDLTs furnished on or after July 1, 1984 in a physician's 
office, by an independent laboratory, or in limited circumstances by a 
hospital laboratory for its outpatients or non-patients are paid under 
the Medicare CLFS, with certain exceptions. Under this section, tests 
are paid the lesser of (1) the billed amount, (2) the fee schedule 
amount established by Medicare contractors, or (3) a National 
Limitation Amount (NLA), which is a percentage of the median of all the 
state and local fee schedules.
    Under the current system, the CLFS amounts are updated for 
inflation based on the percentage change in the Consumer Price Index 
for all urban consumers (CPI-U) and reduced by a multi-factor 
productivity adjustment (see section 1833(h)(2)(A) of the Act). For CY 
2015, under section 1833(h)(2)(A)(iv)(II) of the Act, we also reduced 
the update amount by 1.75 percentage points. In the past, we have 
implemented other adjustments or did not apply the change in the CPI-U 
to the CLFS for certain years in accordance with statutory mandates. We 
do not otherwise update or change the payment amounts for tests on the 
CLFS. Generally, coinsurance and deductibles do not apply to CDLTs paid 
under the CLFS.
    For any CDLT for which a new or substantially revised HCPCS code 
has been assigned on or after January 1, 2005, we determine the basis 
for and amount of payment based on one of two methodologies--
crosswalking and gapfilling (see section 1833(h)(8) of the Act and 
Sec.  414.500 through Sec.  414.509). The crosswalking methodology is 
used when a new test is comparable in terms of test methods and 
resources to an existing test, multiple existing test codes, or a 
portion of an existing test code on the CLFS. In such a case, CMS 
assigns the new test code the local fee schedule amount and the NLA of 
the existing test and pays for the new test code at the lesser of the 
local fee schedule amount or the NLA. Gapfilling is used when no 
comparable test exists on the CLFS. Under gapfilling, MACs establish 
local amounts for the new test code using the following sources of 
information, if available: (1) Charges for the test and routine 
discounts to charges; (2) resources required to perform the test; (3) 
payment amounts determined by other payors; and (4) charges, payment 
amounts, and resources required for other tests that may be comparable 
or otherwise relevant. Under this gapfilling methodology, an NLA is 
calculated after a year of employing a local amount on the basis of the 
median amount for the test code across all MACs. Once established, in 
most cases, we can only reconsider the crosswalking or gapfilling basis 
and/or amount of payment for new tests for one additional year after 
the basis or payment is initially set. Once the reconsideration process 
is complete, payment cannot be further adjusted (except by a change in 
the CPI-U, the productivity adjustment, and any other adjustments 
required by statute).
    In 2014, Medicare paid approximately $8 billion for CDLTs. As the 
CLFS has grown from approximately 400 tests to over 1,300 tests, some 
test methods have become outdated and some tests may no longer be 
priced appropriately. For example, some tests have become faster and 
cheaper to perform, with little need for manual interaction by 
laboratory technicians, while more expensive and complex tests have 
been developed that bear little resemblance to the simpler tests that 
were performed at the inception of the CLFS.
    Another complexity we must consider is the various types of 
laboratories that bill Medicare under the CLFS. Medicare-enrolled 
laboratories include a mix of national chains that furnish a large menu 
of tests, and small regional operations that may concentrate on a 
specific population, such as nursing home residents, or that have a 
small menu of tests. Physicians' offices also perform certain tests 
that are paid under the CLFS.
2. Statutory Bases for Changes in Payment, Coding, and Coverage 
Policies for Clinical Diagnostic Laboratory Tests
    Section 1834A of the Act, as added by section 216(a) of PAMA, 
requires extensive revisions to the Medicare payment, coding, and 
coverage requirements for CDLTs. In this section, we describe the major 
provisions of section 1834A of the Act, which we are proposing to 
implement in this proposed rule.
    Section 1834A(a)(1) of the Act requires reporting of private payor 
payment rates for CDLTs by applicable laboratories to establish 
Medicare payment rates for tests paid under the

[[Page 59389]]

CLFS. Specifically, each applicable laboratory must report to the 
Secretary, at a time specified by the Secretary and for a designated 
data collection period, applicable information for each CDLT the 
laboratory furnishes during such period for which Medicare payment is 
made. Section 1834A(a)(2) of the Act defines the term ``applicable 
laboratory'' to mean a laboratory that receives a majority of its 
Medicare revenues from sections 1834A, 1833(h) (the statutory 
authorities under which CLFS payments are made), or 1848 (the authority 
under which PFS payments are made) of the Act. Section 1834A(a)(2) of 
the Act also provides that the Secretary may establish a low volume or 
low expenditure threshold for excluding a laboratory from the 
definition of an applicable laboratory, as the Secretary determines to 
be appropriate.
    Section 1834A(a)(3)(A) of the Act defines the term ``applicable 
information'' as the payment rate that was paid by each private payor 
for each CDLT and the volume of such tests for each such payor for the 
data collection period. Under section 1834A(a)(5) of the Act, the 
payment rate reported by a laboratory must reflect all discounts, 
rebates, coupons, and other price concessions, including those 
described in section 1847A(c)(3) of the Act regarding the average sales 
price for Part B drugs or biologicals. Section 1834A(a)(6) of the Act 
further specifies that, where an applicable laboratory has more than 
one payment rate for the same payor for the same test, or more than one 
payment rate for different payors for the same test, the applicable 
laboratory must report each such payment rate and the volume for the 
test at each such rate. This paragraph also provides that, beginning 
January 1, 2019, the Secretary may establish rules to aggregate 
reporting in situations where a laboratory has more than one payment 
rate for the same payor for the same test, or more than one payment 
rate for different payors for the same test. Under section 
1834A(a)(3)(B) of the Act, information about laboratory tests for which 
payment is made on a capitated basis or other similar payment basis is 
not considered ``applicable information'' and is therefore excluded 
from the reporting requirements.
    Section 1834A(a)(4) of the Act defines the term ``data collection 
period'' as a period of time, such as a previous 12-month period, 
specified by the Secretary. Section 1834A(a)(7) of the Act requires 
that an officer of each laboratory must certify the accuracy and 
completeness of the information reported by laboratories. Section 
1834A(a)(8) of the Act defines the term ``private payor'' as a health 
insurance issuer and a group health plan (as such terms are defined in 
section 2791 of the Public Health Service Act), a Medicare Advantage 
plan under Medicare Part C, or a Medicaid managed care organization (as 
defined in section 1903(m) of the Act).
    Section 1834A(a)(9)(A) of the Act authorizes the Secretary to apply 
a CMP in cases where the Secretary determines that an applicable 
laboratory has failed to report, or made a misrepresentation or 
omission in reporting, applicable information under section 1834A(a) of 
the Act for a CDLT. In these cases, the Secretary may apply a CMP in an 
amount of up to $10,000 per day for each failure to report or each such 
misrepresentation or omission. Section 1834A(a)(9)(B) of the Act 
further provides that the provisions of section 1128A of the Act (other 
than subsections (a) and (b)) shall apply to a CMP under this paragraph 
in the same manner as they apply to a CMP or proceeding under section 
1128A(a) of the Act. Section 1128A of the Act governs CMPs that apply 
in general under federal health care programs. Thus, the provisions of 
section 1128A of the Act (specifically sections 1128A(c) through 
1128A(n) of the Act) apply to a CMP under section 1834A(a)(9) of the 
Act in the same manner as they apply to a CMP or proceeding under 
section 1128A(a) of the Act. That is, the existing CMP provisions apply 
to the laboratory data collection process under 1834A of the Act, just 
as the CMP provisions are applied now to other processes, such as the 
Medicare Part B drug data collection process under sections 1847A and 
1927 of the Act.
    Section 1834A(a)(10) of the Act addresses the confidentiality of 
the information reported to the Secretary. Specifically, this paragraph 
provides that, notwithstanding any other provision of law, information 
disclosed by a laboratory under the data reporting requirements is 
confidential and shall not be disclosed by the Secretary or a Medicare 
contractor in a form that discloses the identity of a specific payor or 
laboratory, or prices charged, or payments made to any such laboratory, 
except: (1) As the Secretary determines to be necessary to carry out 
this section; (2) to permit the Comptroller General to review the 
information provided; (3) to permit the Director of the Congressional 
Budget Office to review the information provided; and (4) to permit the 
Medicare Payment Advisory Commission (MedPAC) to review the information 
provided. Section 1834A(a)(11) of the Act further states that a payor 
shall not be identified on information reported under the data 
reporting requirements, and that the name of an applicable laboratory 
shall be exempt from disclosure under the Freedom of Information Act, 5 
U.S.C. 552(b)(3).
    Section 1834A(a)(12) of the Act requires the Secretary to establish 
parameters for the data collection under section 1834A(a) of the Act 
through notice and comment rulemaking no later than June 30, 2015.
    Section 1834A(b) of the Act establishes a new methodology for 
determining Medicare payment rates for CDLTs. Section 1834A(b)(1)(A) of 
the Act provides that, in general, the payment amount for a CDLT 
(except for new ADLTs and new CDLTs) furnished on or after January 1, 
2017, shall be equal to the weighted median determined under section 
1834A(b)(2) of the Act for the test for the most recent data collection 
period. Section 1834A(b)(1)(B) of the Act specifies that the payment 
amounts established under this methodology shall apply to a CDLT 
furnished by a hospital laboratory if the test is paid for separately, 
and not as part of a bundled payment under the hospital outpatient 
prospective payment system (OPPS) (section 1833(t) of the Act). Section 
1834A(b)(2) of the Act provides that the Secretary shall calculate a 
weighted median for each test for the data collection period by 
arraying the distribution of all payment rates reported for the period 
for each test weighted by volume for each payor and each laboratory. 
Section 1834A(b)(4)(A) of the Act states that the payment amounts 
established under this methodology for a year following a data 
collection period shall continue to apply until the year following the 
next data collection period. Moreover, section 1834A(b)(4)(B) of the 
Act specifies that the payment amounts established under section 1834A 
of the Act shall not be subject to any adjustment (including any 
geographic adjustment, budget neutrality adjustment, annual update, or 
other adjustment).
    Section 1834A(b)(3) of the Act requires a phase-in of any reduction 
in payment amounts for a CDLT for each year from 2017 through 2022. 
Specifically, section 1834A(b)(3)(A) of the Act requires that the 
payment amounts determined under the new methodology for a CDLT for 
each of 2017 through 2022 shall not result in a reduction in payments 
for that test for the year that is greater than the ``applicable 
percent'' of the payment amount for the test for the preceding year. 
Section 1834A(b)(3)(B) of the Act defines these maximum applicable

[[Page 59390]]

percent reductions as follows: for each of 2017 through 2019, 10 
percent; and for each of 2020 through 2022, 15 percent. However, 
section 1834A(b)(3)(C) of the Act specifies that this payment reduction 
limit shall not apply to a new CDLT under section 1834A(c)(1) of the 
Act, or to a new ADLT, as defined in section 1834A(d)(5) of the Act.
    Section 1834A(b)(5) of the Act increases by $2 the nominal fee that 
would otherwise apply under section 1833(h)(3)(A) of the Act for a 
sample collected from an individual in a Skilled Nursing Facility (SNF) 
or by a laboratory on behalf of a Home Health Agency (HHA). This 
provision has the effect of raising the sample collection fee from $3 
to $5 when the sample is being collected from an individual in a SNF or 
a laboratory on behalf of an HHA.
    Section 1834A(d)(5) of the Act defines an ADLT to mean a CDLT 
covered under Medicare Part B that is offered and furnished only by a 
single laboratory and not sold for use by a laboratory other than the 
original developing laboratory (or a successor owner) and meets one of 
the following criteria: (1) The test is an analysis of multiple 
biomarkers of deoxyribonucleic acid (DNA), ribonucleic acid (RNA), or 
proteins combined with a unique algorithm to yield a single patient-
specific result; (2) the test is cleared or approved by the FDA; or (3) 
the test meets other similar criteria established by the Secretary.
    Section 1834A(d)(1)(A) of the Act provides that, in the case of an 
ADLT for which payment has not been made under the CLFS prior to April 
1, 2014 (the date of enactment of PAMA), during an initial 3 quarters, 
the payment amount for the test shall be based on the actual list 
charge for the test. Section 1834A(d)(1)(B) of the Act defines the term 
``actual list charge'' for purposes of this provision to mean the 
publicly available rate on the first day at which the test is available 
for purchase by a private payor. For the reporting requirements for 
such tests, under section 1834A(d)(2) of the Act, an applicable 
laboratory will initially be required to comply with the data reporting 
requirements under section 1834A(a) of the Act by the last day of the 
second quarter (Q2) of the initial 3 quarter period. Section 
1834A(d)(3) of the Act requires that, after this initial period, the 
data reported under paragraph 1834A(d)(2) of the Act shall be used to 
establish the payment amount for an ADLT described in section 
1834A(d)(1)(A) of the Act using the payment methodology for CDLTs under 
section 1834A(b) of the Act. This payment amount shall continue to 
apply until the year following the next data collection period.
    Section 1834A(d)(4) of the Act addresses recoupment of payment for 
new ADLTs if the actual list charge exceeds the market rate. 
Specifically, it provides that, if the Secretary determines after the 
initial period that the payment amount for a new ADLT based on the 
actual list charge was greater than 130 percent of the payment rate 
that is calculated based on applicable information using the payment 
methodology for CDLTs under section 1834A(b) of the Act, the Secretary 
shall recoup the difference for tests furnished during that initial 
period.
    Section 1834A(c) of the Act provides for payment of new tests that 
are not ADLTs. Specifically, section 1834A(c)(1) of the Act provides 
that, in the case of a CDLT that is assigned a new or substantially 
revised HCPCS code on or after April 1, 2014 (the date of enactment of 
PAMA), and which is not an ADLT (as defined in section 1834A(d)(5) of 
the Act), during an initial period until payment rates under section 
1834A(b) of the Act are established for the test, payment for the test 
shall be determined on the basis of crosswalking or gapfilling. Section 
1834A(c)(1)(A) of the Act requires application of the crosswalking 
methodology described in Sec.  414.508(a) (or any successor regulation) 
to the most appropriate existing test under the CLFS during that 
period. Section 1834A(c)(1)(B) of the Act provides that, if no existing 
test is comparable to the new test, the gapfilling process described in 
section 1834A(c)(2) of the Act shall be applied. Section 1834A(c)(2) of 
the Act states that this gapfilling process must take into account the 
following sources of information to determine gapfill amounts, if 
available: charges for the test and routine discounts to charges; 
resources required to perform the test; payment amounts determined by 
other payors; charges, payment amounts, and resources required for 
other tests that may be comparable or otherwise relevant; and other 
criteria the Secretary determines to be appropriate. Section 
1834A(c)(3) of the Act further requires that, in determining the 
payment amount under crosswalking or gapfilling processes, the 
Secretary must consider recommendations from the panel established 
under section 1834A(f)(1) of the Act. In addition, section 1834A(c)(4) 
of the Act provides that, in the case of a new CDLT that is not an 
ADLT, the Secretary shall make available to the public an explanation 
of the payment rate for the new test, including an explanation of how 
the gapfilling criteria and panel recommendations described in 
paragraphs (2) and (3) of section 1834A(c) of the Act are applied.
    Section 1834A(e) of the Act sets out coding requirements for 
certain new and existing tests. Specifically, section 1834A(e)(1)(A) of 
the Act requires the Secretary to adopt temporary HCPCS codes to 
identify new ADLTs (as defined in section 1834A(d)(5) of the Act) and 
new laboratory tests that are cleared or approved by the FDA. Section 
1834A(e)(1)(B) of the Act addresses the duration of these temporary new 
codes. Section 1834A(e)(1)(B)(i) of the Act requires the temporary code 
to be effective until a permanent HCPCS code is established (but not to 
exceed 2 years), subject to an exception under section 
1834A(e)(1)(B)(ii) of the Act that permits the Secretary to extend the 
temporary code or establish a permanent HCPCS code, as the Secretary 
determines appropriate.
    Section 1834A(e)(2) of the Act addresses coding for certain 
existing tests. This section requires that, not later than January 1, 
2016, the Secretary shall assign a unique HCPCS code and publicly 
report the payment rate for each existing ADLT (as defined in section 
1834A(d)(5) of the Act) and each existing CDLT that is cleared or 
approved by the FDA for which payment is made under Medicare Part B as 
of April 1, 2014 (PAMA's enactment date), if such test has not already 
been assigned a unique HCPCS code. In addition, section 1834A(e)(3) of 
the Act requires the establishment of unique identifiers for certain 
tests. Specifically, for purposes of tracking and monitoring, if a 
laboratory or a manufacturer requests a unique identifier for an ADLT 
or a laboratory test that is cleared or approved by the FDA, the 
Secretary shall utilize a means to uniquely track such test through a 
mechanism such as a HCPCS code or modifier.
    Section 1834A(f) of the Act addresses requirements for input from 
clinicians and technical experts on issues related to CDLTs. In 
particular, section 1834A(f)(1) of the Act requires the Secretary to 
consult with an expert outside advisory panel that is to be established 
by the Secretary no later than July 1, 2015. This advisory panel must 
include an appropriate selection of individuals with expertise, which 
may include molecular pathologists, researchers, and individuals with 
expertise in clinical laboratory science or health economics, or in 
issues related to CDLTs, which may include the development, validation, 
performance,

[[Page 59391]]

and application of such tests. Under section 1834A(f)(1)(A) of the Act, 
this advisory panel is required to provide input on the establishment 
of payment rates under section 1834A of the Act for new CDLTs, 
including whether to use crosswalking or gapfilling processes to 
determine payment for a specific new test, and the factors to be used 
in determining coverage and payment processes for new CDLTs. Section 
1834A(f)(1)(B) of the Act states that the panel may provide 
recommendations to the Secretary under section 1834A of the Act. 
Section 1834A(f)(2) of the Act requires the panel to comply with the 
requirements of the Federal Advisory Committee Act (5 U.S.C. App.). A 
notice announcing the establishment of the Advisory Panel on CDLTs and 
soliciting nominations for members was published in the October 27, 
2014 Federal Register (79 FR 63919 through 63920). The panel's first 
public meeting was held on August 26, 2015. Information regarding the 
Advisory Panel on CDLTs is available at https://www.cms.gov/Regulations-and-Guidance/Guidance/FACA/AdvisoryPanelonClinicalDiagnosticLaboratoryTests.html.
    Section 1834A(f)(3) of the Act requires that the Secretary continue 
to convene the annual meeting described in section 1833(h)(8)(B)(iii) 
of the Act after the implementation of section 1834A of the Act, for 
purposes of receiving comments and recommendations (and data on which 
the recommendations are based) on the establishment of payment amounts 
under section 1834A of the Act.
    Section 1834A(g) of the Act addresses issues related to coverage of 
CDLTs. Section 1834A(g)(1)(A) of the Act requires that coverage 
policies for CDLTs, when issued by a MAC, be issued in accordance with 
the LCD process, which CMS has outlined in Chapter 13 of the Medicare 
Program Integrity Manual.
    In addition, section 1834A(g)(1)(A) of the Act states that the 
processes governing the appeal and review of CDLT-related LCDs shall 
continue to follow the general rules for LCD review established by CMS 
in regulations at 42 CFR part 426.
    Section 1834A(g)(1)(B) of the Act states that the CDLT-related LCD 
provisions referenced in section 1834A(g) do not apply to the national 
coverage determination (NCD) process (as defined in section 
1869(f)(1)(B) of the Act). Section 1834A(g)(1)(C) of the Act specifies 
that the provisions pertaining to the LCD process for CDLTs, including 
appeals of LCDs, shall apply to coverage policies issued on or after 
January 1, 2015.
    In addition, section 1834A(g)(2) of the Act authorizes the 
Secretary to designate one or more (not to exceed four) MACs to either 
establish LCDs for CDLTs, or to both establish CDLT-related LCDs and 
process Medicare claims for payment for CDLTs, as determined 
appropriate by the Secretary.
    Section 1834A(h)(1) of the Act states that there shall be no 
administrative or judicial review under sections 1869, 1878, or 
otherwise, of the establishment of payment amounts under section 1834A 
of the Act. Section 1834A(h)(2) of the Act provides that the Paperwork 
Reduction Act in chapter 35 of title 44 of the U.S.C. shall not apply 
to information collected under section 1834A of the Act.
    Section 1834A(i) of the Act states that during the period beginning 
on the date of enactment of section 1834A of the Act (April 1, 2014) 
and ending on December 31, 2016, the Secretary shall use the 
methodologies for pricing, coding, and coverage for ADLTs in effect on 
the day before this period. This may include crosswalking or gapfilling 
methods.

II. Provisions of the Proposed Rule

    In this section of the proposed rule, we outline our proposals on 
several topics, including, among others: The definitions of applicable 
laboratory and applicable information; the definitions of ADLTs and new 
ADLTs; the data collection period, and data reporting requirements; 
data integrity; confidentiality and public release of limited data; 
coding for certain CDLTs and ADLTs; payment methodology; and coverage.

A. Definition of Applicable Laboratory

    Section 1834A(a)(1) of the Act requires an ``applicable 
laboratory'' to report applicable information for a data collection 
period for each CDLT the laboratory furnishes during the period for 
which payment is made under Medicare Part B. This reporting begins 
January 1, 2016, and takes place every 3 years thereafter for CDLTs, 
and every year thereafter for ADLTs. Section 1834A(a)(2) of the Act 
defines an applicable laboratory as a laboratory that receives a 
majority of its Medicare revenues from section 1834A and section 
1833(h) (the statutory authorities for the CLFS) or section 1848 (the 
statutory authority for the PFS) of the Act. Section 1834A(a)(2) of the 
Act also allows the Secretary to establish a low volume or low 
expenditure threshold for excluding a laboratory from the definition of 
an applicable laboratory, as the Secretary determines appropriate.
    In establishing a regulatory definition for ``applicable 
laboratory,'' we considered the following issues: (1) How to define 
``laboratory;'' (2) what it means to receive a majority of Medicare 
revenues from sections 1834A, 1833(h), or 1848 of the Act; (3) how to 
apply the majority of Medicare revenues criterion; and (4) whether to 
establish a low volume or low expenditure threshold to exclude an 
entity from the definition of applicable laboratory.
    First, we consider what a laboratory is, and we incorporate our 
understanding of that term in our proposed definition of applicable 
laboratory. The CLFS applies to a wide variety of laboratories (for 
example, national chains, physician offices, hospital laboratories, 
etc.), and it is important that we define laboratory broadly enough to 
encompass every laboratory type that is subject to the CLFS.
    We searched for existing statutory definitions of ``laboratory'' 
that could be appropriate to use for the revised CLFS. However, section 
1834A of the Act does not define laboratory, nor is it defined 
elsewhere in the Medicare statute. So we looked to the Clinical 
Laboratory Improvement Amendments of 1988 (CLIA) for a definition. CLIA 
applies to all laboratories performing testing on human specimens for a 
health purpose, including but not limited to those seeking payment 
under the Medicare and Medicaid programs (42 CFR 493.1). To be paid 
under Medicare, a laboratory must be CLIA-certified (42 CFR 410.32(d) 
and part 493). Therefore, we believe it is appropriate to use the CLIA 
definition of laboratory at Sec.  493.2 for our purposes of defining 
laboratory within the term applicable laboratory. We did not consider 
alternative definitions of laboratory as we were not able to identify 
alternative defainitions that would be appropriate for consideration 
under section 1834A of the Social Security Act. Nevertheless, we 
welcome public comments on alternative definitions of a laboratory that 
may be appropriate for this purpose.
    CLIA defines laboratory as a facility for the biological, 
microbiological, serological, chemical, immunohematological, 
hematological, biophysical, cytological, pathological, or other 
examination of materials derived from the human body for the purpose of 
providing information for the diagnosis, prevention, or treatment of 
any disease or impairment of, or the assessment of the health of, human 
beings. These examinations also include procedures to determine, 
measure, or otherwise

[[Page 59392]]

describe the presence or absence of various substances or organisms in 
the body. Facilities only collecting or preparing specimens (or both) 
or only serving as a mailing service and not performing testing are not 
considered laboratories.
    We believe the same policy is also appropriate for our purposes. In 
addition, the services of those facilities that only collect or prepare 
specimens or serve as a mailing service are not paid on the CLFS. We 
propose to incorporate the CLIA regulatory definition of laboratory 
into our proposed definition of applicable laboratory in Sec.  414.502 
by referring to the CLIA definition at Sec.  493.2 to indicate what we 
mean by laboratory.
    Under the revised payment system for CDLTs, an applicable 
laboratory is the entity that must report applicable information to 
CMS. However, not all entities that meet the CLIA regulatory definition 
of laboratory would be applicable laboratories under our proposal. 
Here, we discuss which entities we believe should be required to report 
applicable information.
    Laboratory business models vary throughout the industry. For 
example, some laboratories are large national networks with multiple 
laboratories under one parent entity. Some laboratories are single, 
independent laboratories that operate individually. Some entities, such 
as hospitals or large practices, include laboratories as well as other 
types of providers and suppliers. We propose that an applicable 
laboratory is an entity that itself is a laboratory under the CLIA 
definition or is an entity that includes a laboratory (for example, a 
health care system that is comprised of one or more hospitals, 
physician offices, and reference laboratories). Within our proposed 
definition of applicable laboratory, we would indicate that if the 
entity is not itself a laboratory, it has at least one component that 
is a laboratory, as defined in Sec.  493.2.
    Whether the applicable laboratory is itself a laboratory or is an 
entity that has at least one component that is a laboratory, the 
applicable laboratory is the entity that would be reporting applicable 
information. Entities that enroll in Medicare must provide a TIN, which 
we use to identify the entity of record that is authorized to receive 
Medicare payments. The TIN-level entity is the entity that reports tax-
related information to the Internal Revenue Service (IRS). When an 
entity reports to the IRS, the entity and its components are all 
associated with that entity's TIN. We would rely on the TIN as the 
mechanism for defining the entity we consider to be the applicable 
laboratory. Therefore, we propose that the TIN-level entity is the 
applicable laboratory.
    Each component of the entity that is a covered health care provider 
under the Health Insurance Portability and Accountability Act of 1996 
(HIPAA) regulations will have an NPI. The NPI is the HIPAA standard 
unique health identifier for health care providers adopted by HHS (45 
CFR 162.406). Health care providers, which include laboratories that 
transmit any health information in electronic form in connection with a 
HIPAA transaction for which the Secretary has adopted a standard, are 
required to obtain NPIs and use them according to the NPI regulations 
at 45 CFR part 162, subpart D. When the TIN-level entity reports tax-
related information to the IRS, it does so for itself and on behalf of 
its component NPI-level entities. We would indicate this in the 
definition of applicable laboratory by stating that the applicable 
laboratory is the entity that reports tax-related information to the 
IRS under a TIN with which all of the NPIs in the entity are 
associated. We also propose to define TIN and NPI in Sec.  414.502 by 
referring to definitions already in the Code of Federal Regulations.
    In making this proposal, we considered defining an applicable 
laboratory at the NPI level instead of the TIN level. Some stakeholders 
have indicated that because they bill Medicare by NPI and not TIN, the 
NPI is the most appropriate level for reporting applicable information 
to Medicare. However, the purpose of the revised Medicare payment 
system is to base CLFS payment amounts on private payor rates for 
CDLTs, which we expect would be negotiated at the level of the entity's 
TIN, as described previously, and not by individual laboratory 
locations at the NPI level. In industry meetings that occurred while 
developing this proposed rule, numerous stakeholders suggested that the 
TIN represents the entity negotiating pricing and is the entity in the 
best position to compile and report applicable information across its 
multiple NPIs when there are multiple NPIs associated with a TIN. We 
believe defining an applicable laboratory by TIN rather than by NPI 
will result in the same applicable information being reported, just at 
a higher level, and will require less reporting, and therefore, would 
be less burdensome to applicable laboratories. In addition to 
potentially being less burdensome, we do not believe reporting at the 
TIN level would affect or diminish the quality of the applicable 
information reported. To the extent the information is accurately 
reported, reporting at a higher organizational level should produce 
exactly the same applicable as reporting at a lower level. Therefore, 
we are proposing to define applicable laboratory by TIN rather than by 
NPI. However, we solicit public comments on this aspect of the 
applicable laboratory definition and on whether there are other 
possibly superior approaches to defining an applicable laboratory, 
including by NPI.
    We also considered whether to separate the mechanics of reporting 
from the definition of an applicable laboratory. For example, we 
considered allowing or requiring a corporate entity with multiple TINs 
to provide applicable information for all of its TINs along with a list 
of component TINs. Under this approach, the corporate entity would 
report each distinct private payor rate and the associated volume 
across all component TINs instead of each component TIN reporting 
separately. Thus, if the same rate was paid by a private payor in two 
or more of the corporate entity's component TINs, the entity would 
report the private payor rate once and the associated sum of the volume 
of that test across the component TINs. We believe this approach may be 
operationally less burdensome than submitting separate data files by 
TIN or NPI. We also do not believe that such reporting would affect the 
quality of the applicable information because we should still arrive at 
the same weighted median for each test. We opted not to propose this 
option, however, because we are not yet familiar enough with the 
corporate governance of laboratories to know whether this even higher 
level of reporting would be a desirable or practical option for the 
industry and whether it would affect the quality of the applicable 
information we would receive. We welcome public comments on allowing a 
corporate entity with which multiple TINs are associated to report 
applicable information for all of its TINs, as we have described.
    Next, we consider what it means for an applicable laboratory to 
receive a majority of Medicare revenues from sections 1834A, 1833(h), 
or 1848 of the Act. We would define Medicare revenues to be payments 
received from the Medicare program, which would include fee-for-service 
payments under Medicare Parts A and B, as well as Medicare Advantage 
payments under Medicare Part C, and prescription drug payments under 
Medicare Part D, and any associated Medicare beneficiary deductible or 
coinsurance amounts for

[[Page 59393]]

Medicare services furnished during the data collection period. We are 
applying the standard meaning of ``majority,'' which is more than 50 
percent. Under our proposal, in deciding whether an entity meets the 
majority criterion of the applicable laboratory definition, it would 
examine its Medicare revenues from sections 1834A, 1833(h), and 1848 of 
the Act to determine if those revenues (including any beneficiary 
deductible and coinsurance amounts), whether from only one or a 
combination of all three sources, constitute more than 50 percent of 
its total revenues under the Medicare program for the data collection 
period. In determining its Medicare revenues from sections 1834A, 
1833(h), and 1848 of the Act, the entity would not include Medicare 
payments made to hospital laboratories for tests furnished for admitted 
hospital inpatients or registered hospital outpatients because payments 
for these patient care services are made under the statutory 
authorities of section 1886(d) of the Act (for the Hospital Inpatient 
Prospective Payment System (IPPS)) and section 1833(t) of the Act (for 
the OPPS), respectively, not sections 1834A, 1833(h), or 1848 of the 
Act. In other words, an entity would need to determine whether its 
Medicare revenues from laboratory services billed on Form CMS 1500 (or 
its electronic equivalent) and paid under the current CLFS (section 
1833(h) of the Act), the CLFS under PAMA (section 1834A of the Act), 
and the PFS (section 1848 of the Act) constitute more than 50 percent 
of its total Medicare revenues for the data collection period.
    Moreover, for the entity evaluating whether it is an applicable 
laboratory, the ``majority of Medicare revenues'' determination would 
be based on the collective amount of its Medicare revenues received 
during the data collection period, whether the entity is a laboratory 
under Sec.  493.2 or is not, but has at least one component that is. We 
propose that the determination of whether an entity is an applicable 
laboratory would be made across the entire entity, including all 
component NPI entities, and not just those NPI entities that are 
laboratories. We are proposing to specify in the definition of 
applicable laboratory that an applicable laboratory is an entity that 
receives, collectively with its associated NPI entities, more than 50 
percent of its Medicare revenues from one or a combination of the 
following sources: 42 CFR part 414, subpart G; and 42 CFR part 414, 
subpart B. The regulatory citations we are proposing to include in the 
definition are the regulatory payment provisions that correspond to the 
three statutory provisions named in section 1834A(a)(2); that is, 
sections 1834A, 1833(h), and 1848 of the Act.
    We note that section 1834A(a)(1) of the Act only mandates reporting 
from entities meeting the definition of an applicable laboratory. We 
believe the purpose of only mandating applicable laboratories to report 
applicable information is to ensure that we use only their applicable 
information to determine payment rates under the CLFS beginning January 
1, 2017, and not information from entities that do not meet the 
definition of applicable laboratory. By specifying that only applicable 
laboratories must report applicable information, and specifying in the 
definition of applicable laboratory that an applicable laboratory must 
receive the majority of its Medicare revenues from PFS or CLFS 
services, we believe the statute intends to limit reporting primarily 
to independent laboratories and physician offices (other than those 
that meet the low expenditure or low volume threshold, if established 
by the Secretary) and not include other entities (such as hospitals, or 
other health care providers) that do not receive the majority of their 
revenues from PFS or CLFS services. For this reason, we are proposing 
to prohibit any entity that does not meet the definition of applicable 
laboratory from reporting applicable information to CMS, which we would 
reflect in paragraph (g) of the data reporting requirements in Sec.  
414.504.
    We expect most entities that fall above or below the ``majority of 
Medicare revenues'' threshold will tend to maintain that status through 
the course of their business. However, it is conceivable that an entity 
could move from above to below the threshold, or vice-versa, through 
the course of its business so that, for example, for services furnished 
in one data collection period, an entity might be over the ``majority 
of Medicare revenues'' threshold, but below the threshold in the next 
data collection period. We propose that an entity that otherwise meets 
the criteria for being an applicable laboratory, would have to report 
applicable information if it is above the threshold in the given data 
collection period. Some entities will not know whether they exceed the 
threshold until after the data collection period is over; in that case, 
they would have to retroactively assess their Medicare revenues during 
the 3-month data reporting period. However, we expect that most 
entities will know whether they exceed the threshold long before the 
end of the data collection period. Under our proposal, an entity would 
need to reevaluate its status as to whether it falls above or below the 
``majority of Medicare revenues'' threshold for every data collection 
period, that is, every year for ADLTs and every 3 years for all other 
CDLTs. This requirement would be reflected in the definition of 
applicable laboratory in Sec.  414.502.
    Finally, we are proposing to establish a low expenditure threshold 
for excluding an entity from the definition of applicable laboratory, 
as permitted under section 1834A(a)(2) of the Act, and we are including 
that threshold in our proposed definition of applicable laboratory in 
Sec.  414.502. We believe it is important to achieve a balance between 
collecting sufficient data to calculate a weighted median that 
appropriately reflects the private market rate for a test, and 
minimizing the reporting burden for entities that receive a relatively 
small amount of revenues under the CLFS. We expect many of the entities 
that meet the low expenditure threshold will be physician offices and 
will have relatively low revenues for laboratory tests paid under the 
CLFS.
    For purposes of determining the low expenditure threshold, we 
reviewed Medicare payment amounts for physician office laboratories and 
independent laboratories from CY 2013 Medicare CLFS claims data. 
Although the statute uses the term ``expenditure,'' in this discussion, 
we use the term ``revenues'' because, from the perspective of 
applicable laboratories, payments received from Medicare are revenues 
rather than expenditures, whereas expenditures refer to those same 
revenues, but from the perspective of Medicare (that is, to Medicare, 
those payments are expenditures). In our analysis, we assessed the 
number of billing physician office laboratories and independent 
laboratories that would otherwise qualify as applicable laboratories, 
but would be excluded from the definition under various revenue 
thresholds. We did not include in our analysis hospitals whose Medicare 
revenues are generally under section 1833(t) of the Act for outpatient 
services and section 1886(d) of the Act for inpatient services, as 
these entities are unlikely to meet the proposed definition of 
applicable laboratory.
    We found that, with a $50,000 revenue threshold, the exclusion of 
data from physician office laboratories and independent laboratories 
with total CLFS revenues below that threshold, did not materially 
affect the quality and sufficiency of the data we needed to set rates. 
In other words, we were able to substantially reduce the number of

[[Page 59394]]

entities that would be required to report (94 percent of physician 
office laboratories and 52 percent of independent laboratories) while 
retaining a high percentage of Medicare utilization (96 percent of CLFS 
spending on physician office laboratories and more than 99 percent of 
CLFS spending on independent laboratories) from applicable laboratories 
that would be required to report. We do not believe that excluding 
certain entities with CLFS revenues below a $50,000 threshold would 
have a significant impact on the weighted median private payor rates.
    With this threshold, using Medicare utilization data, we estimate 
there are only 17 tests whose utilization is completely attributed to 
laboratories that would not be reporting because they fell below a 
$50,000 threshold. We understand that Medicare claims data are not 
representative of the volume of laboratory tests furnished in the 
industry as a whole; however, we believe this was the best information 
available to us for the purpose of determining a low expenditure 
threshold for this proposed rule. Therefore, we propose that any entity 
that would otherwise be an applicable laboratory, but that receives 
less than $50,000 in Medicare revenues under section 1834A and section 
1833(h) of the Act for laboratory tests furnished during a data 
collection period, would not be an applicable laboratory for the 
subsequent data reporting period. In determining whether its Medicare 
revenues from sections 1834A and 1833(h) are at least $50,000, the 
entity would not include Medicare payments made to hospital 
laboratories for tests furnished for hospital inpatients or hospital 
outpatients. In other words, an entity would need to determine whether 
its Medicare revenues from laboratory tests billed on Form CMS 1500 (or 
its electronic equivalent) and paid under the current CLFS (under 
section 1833(h) of the Act) and the revised CLFS (under section 1834A 
of the Act) are at least $50,000. We are proposing that if an 
applicable laboratory receives, collectively with its associated NPI 
entities (which would include all types of NPI entities, not just 
laboratories), less than $50,000 in Medicare revenues for CLFS services 
paid on Form CMS 1500 (or its electronic equivalent), the entity would 
not be an applicable laboratory.
    As discussed in section II.D.1., we are proposing an initial data 
collection period of July 1, 2015, through December 31, 2015 (all 
subsequent data collection periods would be a full calendar year). In 
conjunction with the shortened data collection period for 2015, we are 
proposing to specify that, during the data collection period of July 1, 
2015, through December 31, 2015, to be an applicable laboratory, an 
entity must receive at least $25,000 of its Medicare revenues from the 
CLFS, as set forth in 42 CFR part 414, subpart G. During each 
subsequent data collection period, to be an applicable laboratory, an 
entity would have to receive at least $50,000 of its Medicare revenues 
from the CLFS, as set forth in 42 CFR part 414, subpart G.
    As with the ``majority of Medicare revenues'' threshold, some 
entities will not know whether they meet the low expenditure threshold, 
that is, if they receive at least $50,000 in Medicare CLFS revenues in 
a data collection period (or $25,000 during the initial data collection 
period) until after the data collection period is over; in that case, 
they would have to retroactively assess their total Medicare CLFS 
revenues during the subsequent 3-month data reporting period. However, 
for many entities, it will be clear whether they exceed the low 
expenditure threshold even before the end of the data collection 
period. Under our proposal, an entity would need to reevaluate its 
status as to the $50,000 low expenditure threshold during each data 
collection period, that is, every year for ADLTs and every three years 
for all other CDLTs. We propose to codify the low expenditure threshold 
requirement as part of the definition of applicable laboratory in Sec.  
414.502.
    We are not proposing a low volume threshold at this time. Once we 
obtain applicable information under the new payment system, however, we 
may decide to reevaluate the threshold options in future years and 
propose different or revised policies, as necessary, which we would do 
through notice and comment rulemaking.
    In summary, an applicable laboratory means an entity that reports 
tax-related information to the IRS under a TIN with which all of the 
NPIs in the entity are associated. An applicable laboratory is either 
itself a laboratory, as defined in Sec.  493.2, or, if it is not itself 
a laboratory, has at least one component that is. In a data collection 
period, an applicable laboratory must receive, collectively with its 
associated NPI entities, more than 50 percent of its Medicare revenues 
from either the CLFS or PFS. For the data collection period from July 
1, 2015 through December 31, 2015, for purposes of calculating CY 2017 
payment rates, the applicable laboratory must receive, collectively 
with its associated NPI entities, at least $25,000 of its Medicare 
revenues from the CLFS, and for all subsequent data collection periods, 
at least $50,000 of its Medicare revenues from the CLFS. We propose to 
codify this definition of applicable laboratory in Sec.  414.502.

B. Definition of Applicable Information

    Section 1834A(a)(3) of the Act defines the term ``applicable 
information'' as (1) the payment rate that was paid by each private 
payor for a test during the data collection period, and (2) the volume 
of such tests for each such payor during the data collection period. 
Under section 1834A(a)(5) of the Act, the payment rate reported by a 
laboratory must reflect all discounts, rebates, coupons, and other 
price concessions, including those described in section 1847A(c)(3) of 
the Act relating to a manufacturer's average sales price for drugs or 
biologicals. Section 1834A(a)(6) of the Act states that if there is 
more than one payment rate for the same payor for the same test, or 
more than one payment rate for different payors for the same test, the 
applicable laboratory must report each payment rate and corresponding 
volume for the test. Section 1834A(a)(3)(B) of the Act provides that 
applicable information must not include information about a laboratory 
test for which payment is made on a capitated basis or other similar 
payment basis during the data collection period.
    We are proposing to define applicable information in Sec.  414.502 
as, with respect to each CDLT for a data collection period, each 
private payor rate, the associated volume of tests performed 
corresponding to each private payor rate, the specific HCPCS code 
associated with the test, and not information about a test for which 
payment is made on a capitated basis.
    Several terms and concepts in our proposed definition require 
explanation. First, we address the term ``private payor rate.'' The 
statutory definition of applicable information refers to ``payment 
rate'' as opposed to private payor rate; however, we often use payment 
rate generically to refer to the amount paid by Medicare under the 
CLFS. We believe it could be confusing to the public if we use the term 
``payment rate'' as it relates to both applicable information and the 
amount paid under the CLFS. Because the statute says the payment rate 
is the amount paid by private payors, we believe ``private payor rate'' 
could be used in the context of applicable information rather than 
payment rate. Therefore, hereafter, we refer to the private payor rate 
in regard to applicable information, and we do so even when we are 
referring to the

[[Page 59395]]

statutory language that specifically references payment rate. When we 
use the term ``payment rate'' hereafter, unless we indicate otherwise, 
we are referring to the Medicare payment amount under the CLFS. In our 
proposed definition of private payor rate, we attempt to be clear that 
we are limiting the term to its use in the definition of applicable 
information.
    Regarding the definition of ``private payor rate,'' the statute 
indicates that applicable laboratories are to report the private payor 
rate ``that was paid by each private payor,'' and that the private 
payor rate must reflect all price concessions. The private payor rate, 
as we noted previously, is the amount that was paid by a private payor 
for a CDLT, and we are proposing to incorporate that element into our 
proposed definition of private payor rate. To calculate a CLFS amount, 
we believe it is necessary to include in private payor rates patient 
deductible and coinsurance amounts. (Note: In the discussion below, 
``patient'' refers to a privately insured individual while 
``beneficiary'' refers to a Medicare beneficiary.) For example, if a 
private payor paid a laboratory $80 for a particular test, but the 
payor required the patient to pay the laboratory 20 percent of the cost 
of that test as coinsurance, meaning the private payor actually paid 
the laboratory only $64, the laboratory would report a private payor 
rate of $80 (not $64), to reflect the patient coinsurance. The 
alternative would be for private payor rates to not include patient 
deductibles and coinsurance (such policy would yield $64 in the above 
example). Thus, the issue of whether we propose to include or exclude 
patient deductible and coinsurance in the definition of private payor 
rate has a material effect on the private payor rate and, ultimately, 
the payment amount determined by CMS. As CMS generally does not require 
a beneficiary to pay a deductible or coinsurance on CLFS services, we 
believe it is important for private payor rates to be reported 
analogous to how they will be used by CMS to determine the Medicare 
payment amount for CDLTs under the new payment methodology. For this 
reason, we are proposing that applicable laboratories must report 
private payor rates inclusive of all patient cost sharing amounts.
    With regard to price concessions, section 1834A of the Act is clear 
that the private payor rate is meant to reflect the amount paid by a 
private payor less any price concessions that were applied to a CDLT. 
For example, there may be a laboratory that typically charges $10 for a 
particular test, but offers a discount of $2 per test if a payor 
exceeds a certain volume threshold for that test in a given time 
period. If the payor exceeds the volume threshold, the private payor 
rate for that payor for that test, taking into account the $2 discount, 
is $8. The statute lists specific price concessions in section 
1834A(a)(5) of the Act--discounts, rebates, and coupons; and in section 
1847A(c)(3) of the Act--volume discounts, prompt pay discounts, cash 
discounts, free goods that are contingent on any purchase requirement, 
chargebacks, and rebates (except for Medicaid rebates under section 
1927 of the Act). These lists are examples of price concessions, and, 
we believe, are not meant to be exhaustive. Other price concessions 
that are not specified in section 1834A of the Act might be applied to 
the amounts paid by private payors, and we would expect those to be 
accounted for in the private payor rate. Within our definition of 
private payor rate, we are proposing that the amount paid by a private 
payor for a CDLT must be the amount after all price concessions were 
applied.
    We propose to codify the definition of private payor rate in Sec.  
414.502. Specifically, we propose that the private payor rate, with 
respect to applicable information, is the amount that was paid by a 
private payor for a CDLT after all price concessions were applied, and 
includes any patient cost sharing amounts, if applicable.
    Next, we address the definition of ``private payor.'' Section 
1834A(a)(3)(i) of the Act specifies that applicable information is the 
private payor rate paid by each private payor. Section 1834A(a)(8) of 
the Act defines private payor as (A) a health insurance issuer and a 
group health plan (as such terms are defined in section 2791 of the 
Public Health Service Act), (B) a Medicare Advantage plan under part C, 
and (C) a Medicaid managed care organization (as defined in section 
1903(m) of the Act).
    A health insurance issuer is defined in section 2791(b)(2) of the 
Public Health Service (PHS) Act in relevant part, as an insurance 
company, insurance service, or insurance organization (including a 
health maintenance organization) which is licensed to engage in the 
business of insurance in a State and which is subject to State law 
which regulates insurance (within the meaning of section 514(b)(2) of 
the Employee Retirement Income Security Act of 1974 (ERISA)). Such term 
does not include a group health plan. We would incorporate this 
definition of health insurance issuer into our proposed definition of 
private payor by referring to the definition at section 2791(b)(2) of 
the PHS Act.
    Section 2791(a)(1) of the PHS Act defines a group health plan, in 
relevant part, as an employee welfare benefit plan (as defined in 
section 3(1) of ERISA to the extent that the plan provides medical care 
and including items and services paid for as medical care) to employees 
or their dependents (as defined under the terms of the plan) directly 
or through insurance, reimbursement, or otherwise. We would incorporate 
this definition of group health plan into our definition of private 
payor by referring to the definition at section 2791(a)(1) of the PHS 
Act.
    A Medicare Advantage plan under part C is defined in section 
1859(b)(1) of the Act as health benefits coverage offered under a 
policy, contract, or plan by a Medicare+Choice organization pursuant to 
and in accordance with a contract under section 1857. We would 
incorporate this definition of Medicare Advantage plan into our 
definition of private payor by referring to the definition in section 
1859(b)(1) of the Act.
    A Medicaid managed care organization is defined in section 
1903(m)(1)(A) of the Act, in relevant part, as a health maintenance 
organization, an eligible organization with a contract under section 
1876 or a Medicare+Choice organization with a contract under Medicare 
Part C, a provider sponsored organization, or any other public or 
private organization, which meets the requirement of section 1902(w) of 
the Act and (i) makes services it provides to individuals eligible for 
benefits under Medicaid accessible to such individuals, within the area 
served by the organization, to the same extent as such services are 
made accessible to individuals (eligible for medical assistance under 
the State plan) not enrolled with the organization, and (ii) has made 
adequate provision against the risk of insolvency, which provision is 
satisfactory to the State, meets the requirements under section 
1903(m)(1)(C)(i) of the Act (if applicable), and which assures that 
individuals eligible for benefits under Medicaid are in no case held 
liable for debts of the organization in case of the organization's 
insolvency. An organization that is a qualified health maintenance 
organization (as defined in section 1310(d) of the PHS Act) is deemed 
to meet the requirements of clauses (i) and (ii). We would incorporate 
this definition of Medicaid managed care organization into our 
definition of private payor by referring to the definition at section 
1903(m)(1)(A) of the Act.
    We propose to codify the definition of ``private payor'' in Sec.  
414.502 as a health

[[Page 59396]]

insurance issuer, as defined in section 2791(b)(2) of the PHS Act; a 
group health plan, as defined in section 2791(a)(1) of the PHS Act; a 
Medicare Advantage plan under Medicare Part C, as defined in section 
1859(b)(1) of the Act; or a Medicaid managed care organization, as 
defined in section 1903(m)(1)(A) of the Act.
    Next, section 1834A(a)(3) of the Act requires that applicable 
information include the private payor rate for each test and the 
``volume of such tests'' for each private payor. Regarding the volume 
reporting requirement, we are aware that sometimes laboratories are 
paid different amounts for the same CDLT by a payor. And, sometimes 
laboratories are paid different amounts for the same CDLT by different 
payors. Section 1834A(a)(6) of the Act specifies that an applicable 
laboratory must report each such private payor rate and associated 
volume for the CDLT. Accordingly, we are proposing that each applicable 
laboratory must report each private payor rate for each CDLT and its 
corresponding volume. For example, an applicable laboratory and private 
payor may agree on a volume discount for a particular test whereby the 
first 100 tests will be reimbursed at $100. The 101st test (and all 
thereafter) will be reimbursed at $90. In reporting to CMS, the 
laboratory would report two different private payor rates for this 
private payor. The first would be 100 tests at a private payor rate of 
$100 per test, and the second, $90 for all tests reimbursed thereafter. 
We are proposing to implement the volume reporting requirement by 
including in the proposed definition of applicable information in Sec.  
414.502 that, in addition to ``each'' private payor rate for ``each'' 
CDLT, applicable information is the associated volume of tests 
performed corresponding to each private payor rate.
    We will also need to be able to identify the particular test for 
which private payor information is being reported. As CLFS tests are 
identified by HCPCS codes (see section II.G. of this proposed rule for 
discussion of coding), applicable laboratories will need to report a 
HCPCS code for each test that specifically identifies the test being 
reported. We are proposing to include in Sec.  414.502 that applicable 
information includes the specific HCPCS code associated with each CDLT. 
Some laboratory tests are currently billed using unlisted CPT codes or 
HCPCS level II miscellaneous/not otherwise classified (NOC) codes. 
Because NOC codes and unlisted CPT codes do not describe a single test 
and may be used to bill and pay for multiple types of tests, we would 
not be able to determine the specific laboratory test corresponding to 
a reported private payor rate if either was used for reporting. 
Therefore, to ensure that applicable laboratories do not report 
applicable information with a NOC code or an unlisted CPT code, we are 
also proposing to define ``specific HCPCS code'' in Sec.  414.502 as a 
HCPCS code that does not include an unlisted CPT code, as established 
by the American Medical Association, or a NOC code, as established by 
the CMS HCPCS Workgroup.
    Finally, the statute specifies that applicable information does not 
include certain information listed in section 1834A(a)(3)(B) of the 
Act--information for a laboratory test for which payment is made on a 
capitated basis or other similar payment basis during the data 
collection period. A capitated payment is made for health care services 
based on a set amount for each enrolled beneficiary in the plan for a 
given period of time, regardless of whether the particular beneficiary 
receives services during the period covered by the payment. Payment is 
typically made on a capitated basis under a managed care arrangement. 
As there is no way to determine payment specifically for a given test, 
it cannot be reported as applicable information. Therefore, we are 
proposing to specify in the definition of applicable information in 
Sec.  414.502 that the term does not include information about a test 
for which payment is made on a capitated basis. We do not believe that 
providing a discount based on volume of tests furnished is an example 
of a payment made on a capitated basis or other similar payment basis.

C. Definition of Advanced Diagnostic Laboratory Tests (ADLTs) and New 
ADLTs

    The statute applies different reporting and payment requirements to 
ADLTs than to other CDLTs, and further distinguishes a subset of ADLTs 
called ``new ADLTs.'' In this section, we discuss our proposed 
definitions for the terms ``advanced diagnostic laboratory test'' and 
``new advanced diagnostic laboratory test.''
1. Definition of ADLT
    Section 1834A(d)(5) of the Act defines an ADLT as a CDLT covered 
under Medicare Part B that is offered and furnished only by a single 
laboratory and not sold for use by a laboratory other than the original 
developing laboratory (or a successor owner) and that meets one of the 
following criteria: (1) The test is an analysis of multiple biomarkers 
of DNA, RNA, or proteins combined with a unique algorithm to yield a 
single patient-specific result; (2) the test is cleared or approved by 
the FDA; (3) the test meets other similar criteria established by the 
Secretary. Sections 1834A(d)(1) and (2) of the Act recognize special 
reporting and payment requirements for ADLTs for which payment has not 
been made under the CLFS prior to April 1, 2014 (PAMA's enactment 
date). In establishing a regulatory definition for ADLT, we considered 
each component of the statutory definition at section 1834A(d)(5) of 
the Act, and we explain here how we interpret and incorporate key 
statutory terms and phrases.
    We believe that, by including these provisions for ADLTs, the 
statute seeks to establish special payment status for tests that are 
unique and are provided only by the laboratory that developed the test, 
or a subsequent owner of that laboratory. In other words, we view the 
statute as intending to award special payment status to the one 
laboratory that is expending the resources for all aspects of the 
test--developing it, marketing it to the public, performing it, and 
selling it. It is with this understanding that we developed our 
proposed policies for defining ADLTs.
    First, to be an ADLT, a test must meet the requirements specified 
in the first part of the definition at section 1834A(d)(5) of the Act, 
that is, it must be a CDLT covered under Medicare Part B that is 
offered and furnished only by a single laboratory and not sold for use 
by a laboratory other than the original developing laboratory (or a 
successor owner). With regard to the meaning of ``single laboratory,'' 
we believe the statute intends to ensure that we grant ADLT status to 
the one laboratory that offers and furnishes in the particular test, to 
the exclusion of all other laboratories. The way we propose to ensure 
this is the case, is to require the laboratory to be a facility with a 
single CLIA certificate as described in Sec.  493.43(a) and (b) because 
we believe, in most instances, the laboratory's single CLIA certificate 
will correspond to one laboratory location, or facility. Under our 
proposal, an entity with multiple CLIA certificates would not be a 
single laboratory. For example, a test offered by a health system 
consisting of multiple entities, including physician offices and 
independent laboratories, and that has multiple CLIA certificates 
associated with its multiple testing locations, would not be eligible 
for ADLT status, even if the test met all other ADLT criteria. Section 
493.43(b) includes several narrow exceptions for certain types of 
laboratories that may

[[Page 59397]]

have multiple locations.\1\ We do not believe those exceptions would 
apply to most or all laboratories seeking ADLT status for a given test 
and, even if they did, we do not believe those particular exceptions 
would undermine our effort to identify the single laboratory. We 
request comment on the impact of using the CLIA certificate to 
designate a single laboratory.
---------------------------------------------------------------------------

    \1\ Section 493.43(b) includes the following exceptions: (1) 
Laboratories that are not at a fixed location; (2) not-for-profit or 
Federal, State, or local government laboratories that engage in 
limited (not more than a combination of 15 moderately complex or 
waived tests per certificate) public health testing; and (3) 
laboratories that are within a hospital that are located at 
contiguous buildings on the same campus and under common direction.
---------------------------------------------------------------------------

    Next, the statute directs that the test must be ``offered and 
furnished'' by a laboratory seeking ADLT status for the test. It also 
requires that the test be ``not sold for use by a laboratory other than 
the original developing laboratory.'' We interpret the original 
developing laboratory referenced in the statute to be the same 
laboratory that offers and furnishes the test. This interpretation is 
consistent with our understanding that the statute intends for special 
payment status to be awarded to the one laboratory that is expending 
the resources for all aspects of the test. Within the two 
requirements--(1) that a laboratory seeking ADLT status must offer and 
furnish the test and (2) that the test is not sold for use by a 
laboratory other than the original developing laboratory--there are 
several components for us to parse, and we do so consistent with our 
view of the statutory intent. First, we believe a laboratory offers and 
furnishes a test when it markets and performs the test. The laboratory 
that markets and performs the test must also be the only one to sell 
it, that is, to receive remuneration in exchange for performing the 
test. In addition, that laboratory must also be the one that developed 
the test, which means the laboratory designed it. We are aware that, in 
certain circumstances, a referring laboratory may bill for a test under 
section 1833(h)(5)(A) of the Act. The referring laboratory is a 
laboratory that receives a specimen to be tested and refers it to 
another laboratory, the reference laboratory, to perform the test. In 
these situations, because the reference laboratory performed the test, 
it would be the laboratory that offered and furnished the test for 
purposes of the ADLT definition.
    Accordingly, under our proposal, only one laboratory may design, 
market, perform, and sell the test. If more than the one laboratory 
engages in any of one of those activities, the test would not meet the 
criteria to be an ADLT. If our proposal is finalized, we would not 
expect to see more than one applicable laboratory report applicable 
information for an ADLT.
    Next, the statute permits a successor owner to the original 
developing laboratory to sell the test without disqualifying the test 
for ADLT status. We propose to define successor owner as a laboratory 
that has assumed ownership of the original developing laboratory, and 
meets all other aspects of the ADLT definition (except for being the 
original developing laboratory). This means the successor owner is a 
single laboratory that markets, performs, and sells the ADLT.
    In considering how to define successor owner, we looked to our 
regulations at Sec.  489.18(a), which describe what constitutes a 
change of ownership for Medicare providers. Although laboratories are 
suppliers and not providers, we believe the language in this regulation 
appropriately applies to the wide range of potential changes in 
ownership for laboratories. Specifically, we propose to incorporate the 
scenarios described in Sec.  489.18(a) as follows. A successor owner, 
for purposes of an ADLT, means a single laboratory that has assumed 
ownership of the laboratory that designed the test through any of the 
following circumstances:
     Partnership. In the case of a partnership, the removal, 
addition, or substitution of a partner, unless the partners expressly 
agree otherwise, as permitted by applicable State law, constitutes 
change of ownership.
     Unincorporated sole proprietorship. Transfer of title and 
property to another party constitutes change of ownership.
     Corporation. The merger of the original developing 
laboratory corporation into another corporation, or the consolidation 
of two or more corporations, including the original developing 
laboratory, resulting in the creation of a new corporation constitutes 
change of ownership. However, a transfer of corporate stock or the 
merger of another corporation into the original developing laboratory 
corporation does not constitute change of ownership.
     Leasing. The lease of all or part of the original 
developing laboratory facility constitutes change of ownership of the 
leased portion.
    In the case of a lease, all of or part of the original developing 
laboratory is leased by the owner(s) of the original developing 
laboratory to another entity who takes over the continued production of 
the test, and the owner(s) of the original developing laboratory 
becomes the lessor of the laboratory where it formerly provided 
laboratory tests. In this situation, there would be a change of 
ownership of the leased portion of the laboratory, and the lessee would 
become the successor owner that could be paid for performing an ADLT, 
provided the test meets all other criteria for being an ADLT.
    As we noted above, the successor owner would need to be a single 
laboratory and meet all other aspects of the ADLT definition. For 
example, under our proposal, if an original developing laboratory 
corporation is merged into another laboratory corporation that has 
multiple CLIA certificates, while the test would still be a CDLT, it 
would no longer be considered an ADLT. If this proposal is finalized, 
we would expect a laboratory that obtains CMS approval of ADLT status 
for a test to maintain documentation on changes of ownership with 
transfer of rights to market, perform, and sell the ADLT to support 
correct claims submission and payment. We are soliciting comments on 
our proposed definition of successor owner and, in particular, whether 
different change of ownership requirements may be more appropriate for 
the laboratory industry.
    To summarize, we propose to implement the first part of the ADLT 
definition in section 1834A(d)(5) of the Act by stating that an ADLT is 
a CDLT covered under Medicare Part B that is marketed and performed 
only by a single laboratory and not sold for use by a laboratory other 
than the laboratory that designed the test or a successor owner of that 
laboratory. We would define the terms ``single laboratory'' and 
``successor owner'' in Sec.  414.502. If this proposal is finalized, we 
plan to monitor compliance by confirming that applicable information 
for each ADLT is reported by a single laboratory. As part of that 
process, we would confirm that each applicable laboratory that reports 
applicable information for an ADLT has a single CLIA certificate.
    Next, in addition to meeting the first part of the ADLT definition 
at section 1834A(d)(5) of the Act, the statute requires that an ADLT 
must meet one of the criteria described in paragraphs (5)(A), (5)(B), 
or (5)(C). Criterion A of section 1834A(d)(5) of the Act states that 
the test is an analysis of multiple biomarkers of DNA, RNA, or proteins 
combined with a unique algorithm to yield a single patient-specific 
result. We interpret this provision to require that the test analyze, 
at a minimum, biomarkers of DNA or RNA. Tests that analyze nucleic 
acids (DNA or RNA) are

[[Page 59398]]

molecular pathology analyses. Therefore, we are proposing that, under 
criterion A, a test must be a molecular pathology analysis of DNA or 
RNA. Examples of such tests include those that analyze the expression 
of a gene, the function of a gene, or the regulation of a gene. The 
statute also requires that the test analyze ``multiple'' biomarkers of 
DNA, RNA, or proteins. Therefore, an ADLT might consist of one test 
that analyzes multiple biomarkers or it might consist of multiple tests 
that each analyzes one or more biomarkers.
    That the analysis of the biomarkers must be ``combined with a 
unique algorithm to yield a single patient-specific result'' indicates 
to us that the algorithm must be empirically derived, and that the 
ultimate test result must be diagnostic of a certain condition, a 
prediction of the probability of an individual developing a certain 
condition(s), or the probability of an individual's response to a 
particular therapy(ies). Furthermore, the statute requires the result 
to be a single patient-specific one, so the test must diagnose a 
certain condition for an individual, or predict the probability that a 
specific individual patient will develop a certain condition(s) or 
respond to a particular therapy(ies). We are also proposing that the 
test must provide new clinical diagnostic information that cannot be 
obtained from any other existing test on the market or combination of 
tests (for example, through a synthesis of the component molecular 
pathology assays included in the laboratory test in question). We 
considered requiring that a new ADLT be clinically useful, as well as 
new, but decided against such a policy due to statutory limitations. 
These proposed policies for implementing criterion A derive from our 
view that ADLTs that meet the criterion are innovative tests that are 
new and different from any prior test already on the market and provide 
the individual patient with valuable genetic information to predict the 
trajectory of the patient's disease process or response to treatment of 
the patient's disease that could not be gained from another test or 
tests on the market. Finally, we expect that an ADLT could include 
assays in addition to the biomarker assay(s) described above. For 
example, in addition to an analysis of a DNA biomarker, an ADLT might 
also include a component that analyzes proteins. We would not 
disqualify a test from ADLT status consideration if that is the case. 
In summary, we propose that to qualify as an ADLT under criterion A of 
section 1834A(d)(5) of the Act, a test: (i) Must be a molecular 
pathology analysis of multiple biomarkers of DNA, or RNA; (ii) when 
combined with an empirically derived algorithm, yields a result that 
predicts the probability a specific individual patient will develop a 
certain condition(s) or respond to a particular therapy(ies); (iii) 
provides new clinical diagnostic information that cannot be obtained 
from any other test or combination of tests; and (iv) may include other 
assays. We reflect this proposed requirement in paragraph (1) of the 
ADLT definition in Sec.  414.502.
    Criterion B of section 1834A(d)(5) of the Act states that the test 
is cleared or approved by the FDA. The FDA considers CDLTs to be 
medical devices, and has two distinct application processes for 
clearing and approving medical devices. To receive FDA clearance to 
market a new device, a Premarket Notification submission, also referred 
to as a 510(k), is submitted to FDA for review at least 90 days before 
introducing, or delivering for introduction, the device into interstate 
commerce. Before FDA can clear a 510(k) and allow a device to be 
commercialized, the 510(k) submitter must demonstrate that their 
medical device is ``substantially equivalent'' to a device that is 
legally marketed for the same use and for which a Premarket Approval 
Application (PMA) is not required. A request for FDA approval of a 
device is typically submitted through a PMA, which is the most 
stringent type of device marketing application required by FDA. 
According to the FDA's ``Overview of Medical Devices and Their 
Regulatory Pathways'' (available on the FDA's Web site at https://www.fda.gov/), a PMA refers to the scientific and regulatory review 
necessary to evaluate the safety and effectiveness of devices that were 
found either not substantially equivalent through the 510(k) [Premarket 
Notification] process or devices for which insufficient information 
exists to determine that general controls (Class I) and special 
controls (Class II) would provide a reasonable assurance of its safety 
and effectiveness. To obtain FDA approval of a device, an applicant 
must submit a PMA which contains valid scientific evidence to assure 
that the device is safe and effective for its intended use(s). We 
further note that FDA regulations exempt certain low-risk devices from 
approval or clearance and allow them to be legally marketed immediately 
without any form of premarket approval or clearance. Since criterion B 
of section 1834A(d)(5) of the Act requires FDA approval or clearance, 
we do not intend for this criterion to cover any devices that are, by 
regulation, exempt from FDA approval or clearance. We propose that a 
laboratory test can be considered an ADLT if it is cleared or approved 
by the FDA and meets all other aspects of the ADLT definition. Under 
criterion B, laboratories would have to submit documentation of their 
FDA clearance or approval for the test. This process would be outlined 
through subregulatory processes prior to January 1, 2016.
    To implement criteria A and B, we would establish guidelines for 
laboratories to apply for ADLT status and submit documentation to 
support their application. For example, if our proposed definition of 
criterion A is finalized, laboratories would have to submit to CMS 
evidence of their empirically derived algorithms and show how their 
test provides new clinical diagnostic information that cannot be 
obtained from any other test or combination of tests. As we note in 
section II.F. of this proposed rule, section 1834A(a)(10) of the Act 
provides for confidentiality of the information disclosed by a 
laboratory under section 1834A(a) of the Act. As this statutory 
provision is limited to ``this subsection'' (that is, subsection (a)), 
it does not apply to subsection (d) of section 1834A of the Act, which 
relates to information provided to the Secretary to determine whether a 
test is an ADLT. While we do not expect to make information in an ADLT 
application available to the public, that information is not explicitly 
protected from disclosure under the confidentiality provisions of the 
statute, nor is it explicitly protected from disclosure in response to 
a Freedom of Information Act (FOIA) request, as is information 
disclosed by a laboratory under subsection (a), per section 
1834A(a)(11) of the Act. However, we note that FOIA includes an 
exemption for trade secrets and commercial or financial information 
obtained from a person that is privileged or confidential. An ADLT 
applicant should be aware that information in an ADLT application may 
not be protected from public disclosure even if it is marked as 
confidential and proprietary. We cannot guarantee that information 
marked as proprietary and confidential will not be subject to release 
under FOIA. While a party may mark information as confidential and 
proprietary, the information may be subject to disclosure under FOIA 
unless, consistent with FOIA exemption (b)(4), the information relates 
to trade secrets and commercial or financial information that is exempt 
from disclosure. The ADLT applicant would need to substantiate this

[[Page 59399]]

confidentiality by expressly claiming substantial competitive harm if 
the information is disclosed and demonstrating such in a separate 
statement how the release would cause substantial competitive harm 
pursuant to the process in E.O. 12600 for evaluation by CMS (please see 
Section II.F of this rule for further discussion of the confidentiality 
and public release of data).
    Criterion C of section 1834A(d)(5) of the Act gives the Secretary 
the authority to establish and apply other similar criteria by which to 
determine that a test is an ADLT. At this time, we are not proposing to 
exercise this authority; if we do so in the future, it would be through 
notice and comment rulemaking.
2. Definition of New ADLT
    Section 1834A(d) of the Act is titled ``Payment for New Advanced 
Diagnostic Laboratory Tests.'' As previously discussed in this section, 
section 1834A(d)(1)(A) provides special payment rules for ADLTs for 
which payment has not been made under the CLFS prior to April 1, 2014, 
the enactment date of PAMA. Section 1834A(i) of the Act, titled 
``Transitional Rule,'' provides that during the period beginning on 
April 1, 2014, PAMA's enactment date, and ending on December 31, 2016, 
for ADLTs under Medicare Part B, the Secretary shall use the 
methodologies for pricing, coding, and coverage in effect on the day 
before April 1, 2014, which may include crosswalking or gapfilling 
methods. We interpret section 1834A(i) of the Act to mean that we must 
use the current CLFS payment methodologies for ADLTs that are furnished 
between April 1, 2014, and December 31, 2016.
    Accordingly, we propose to define a new ADLT as an ADLT for which 
payment has not been made under the CLFS prior to January 1, 2017. Any 
ADLT paid for under the CLFS prior to January 1, 2017, would be an 
existing ADLT and would be paid in accordance with the current 
regulations at 42 CFR part 414, subpart G, including gapfilling and 
crosswalking methodologies. In other words, there would be no new ADLTs 
until January 1, 2017, and they would be first paid on the CLFS using 
the payment methodology for new ADLTs proposed in Sec.  414.522. We 
would codify the definition of ``new ADLT'' at Sec.  414.502 to mean an 
ADLT for which payment has not been made under the CLFS prior to 
January 1, 2017. A full discussion of our proposed payment policies for 
new ADLTs is provided in section II.H.3. of this proposed rule.

D. Data Collection and Data Reporting

1. Definitions
    Section 1834A(a) of the Act requires applicable laboratories to 
report applicable information. The information is gathered or collected 
during a ``data collection period'' and then reported to the Secretary 
during a ``data reporting period.'' Under the statute, the Secretary is 
to specify the period of time that is the data collection period and 
the timeframe for the data reporting period. In this section, we 
propose to define the terms ``data collection period'' and ``data 
reporting period.'' In determining what the data collection and data 
reporting periods should be, we considered our objectives to: (1) 
Provide applicable laboratories sufficient notice of their obligation 
to collect and report applicable information to CMS; (2) allow 
applicable laboratories enough time to collect and report applicable 
information; (3) give CMS enough time to process applicable information 
to determine a CLFS payment rate for each laboratory test; and (4) 
publish new CLFS payment rates at least 60 days in advance of January 1 
so laboratories will have sufficient time to review the data used to 
calculate CLFS payment rates and prepare for implementation of the new 
CLFS rates on January 1.
    Section 1834A(a)(4) of the Act defines the term ``data collection 
period'' as a period of time, such as a previous 12-month period, 
specified by the Secretary. Except for the first data collection period 
(which we discuss in this section), we believe the data collection 
period should be a full calendar year, for example, January 1 through 
December 31, because a full calendar year of applicable information 
would provide a comprehensive set of data for calculating CLFS rates. 
In addition, we have chosen to define a data collection period as a 
calendar year as opposed to, for example, a federal fiscal year 
(October through September), so the data collection period coordinates 
with the timing of the CLFS payment schedule, wherein updated CLFS 
payment rates are in effect on January 1 of each year. We also believe 
the data collection period should immediately precede the data 
reporting period, which is the time period during which applicable 
laboratories must report applicable information to CMS. For example, 
the data reporting period for the 2018 data collection period (January 
1, 2018, through December 31, 2018) would begin on January 1, 2019. We 
believe that having the data collection period immediately precede the 
data reporting period will result in more accurate reporting by 
laboratories and, thus, more accurate rate setting by CMS, because 
laboratories will have more recent experience, and therefore, be more 
familiar with the information they are reporting. Further, starting the 
data reporting period immediately after the data collection period will 
limit the lag time between reporting applicable information and the use 
of that applicable information to determine Medicare CLFS payments, 
thus ensuring that CMS is using the most recent data available to set 
CLFS payment rates. For these reasons, we propose to codify in Sec.  
414.502 that the data collection period is the calendar year during 
which an applicable laboratory collects applicable information and that 
immediately precedes the data reporting period.
    We are proposing a special rule for the 2015 data collection 
period, which would begin July 1, 2015, and end December 31, 2015. 
While our preference would have been for the data collection period to 
be a full calendar year, as we are proposing for subsequent data 
collection periods, and for it to begin after publication of proposed 
and final rules implementing section 1834A of the Act, we believe the 
statute contemplates that the first data collection period would begin 
prior to publication of regulations establishing the parameters for 
data collection. Given that the statute, which was enacted on April 1, 
2014, requires us to establish the parameters for data collection 
through rulemaking by June 30, 2015, the first data collection period 
that would allow for reporting in 2016 and implementation of the new 
payment system on January 1, 2017, would have to be in 2015. As the 
statute indicates that a data collection period could be a 12-month 
period, and data collection requirement regulations do not have to be 
complete until June 30, 2015, we believe the statute anticipates that 
the first data collection period would begin prior to publication of 
the June 30, 2015 regulations, that is, 6 months prior to a final 
regulation. In addition, section 1834A(a)(4) of the Act does not 
require the data collection period to be a 12-month period, but rather, 
suggests that it could be, and provides CMS the authority to determine 
the length of the period. Therefore, although we could have chosen to 
make the 2015 data collection period a full calendar year, given that 
laboratories would not have notice of the data collection period until 
our regulations were proposed and finalized, we believe it is 
reasonable to limit the time period of the first data collection period 
to 6 months, which is consistent with the length of time the data 
collection period would have been

[[Page 59400]]

in effect prior to a final rule if we had adopted a full calendar year 
data collection period in 2015 and published regulations specifying 
that to be the case on June 30, 2015. While we believe a full calendar 
year of data will be the most robust and comprehensive for setting CLFS 
payment rates, we believe the 6-month data collection period in 2015 
will still provide sufficient, reliable data with which to set rates 
that accurately reflect private payor rates. Therefore, we are 
proposing to include in the definition of data collection period in 
Sec.  414.502 that the data collection period for 2015 is July 1, 2015 
through December 31, 2015.
    Under section 1834A(a)(1) of the Act, beginning January 1, 2016, 
and every 3 years thereafter (or annually in the case of an ADLT), each 
applicable laboratory must report applicable information to the 
Secretary at a time specified by the Secretary. We believe applicable 
laboratories should have 3 months during which to submit applicable 
information from the corresponding data collection period, that is, the 
calendar year immediately preceding the data reporting period. For 
example, for purposes of calculating CY 2017 CLFS rates, the data 
collection period would begin on July 1, 2015, and end on December 31, 
2015, and the data reporting period would be January 1, 2016 through 
March 31, 2016. We believe a 3-month data reporting period is a 
sufficient amount of time for applicable laboratories to report 
applicable information to CMS. It would give CMS adequate time to 
calculate CLFS payment amounts, upload the CLFS rates on Medicare's 
claims processing systems, and make that data publicly available 
(tentatively, first in September and then a final version in November) 
before the CLFS rates go into effect on the following January 1. Given 
the magnitude of the potential changes in CLFS payment rates, to give 
the industry sufficient time to prepare for the next year's fee 
schedule, we believe final CLFS rates for the following year should be 
published at least 60 days prior to the beginning of the next calendar 
year, or no later than November 1. For these reasons, we are proposing 
that the definition of ``data reporting period'' in Sec.  414.502 is 
the 3-month period during which an applicable laboratory reports 
applicable information to CMS and that immediately follows the data 
collection period.
    Table 1 illustrates the data collection period, the data reporting 
period, and CLFS rate year for which the data will be used under our 
proposal for CDLTs.

------------------------------------------------------------------------

    As indicated below, applicable information must be reported 
annually for ADLTs and will follow the above data collection schedule 
on an annual basis after the first data collection period, which will 
be for the first and second quarters of the new ADLT initial period, 
and reported to CMS by the end of the second quarter of the new ADLT 
initial period (described in more detail below).
2. General Data Collection and Data Reporting Requirements
    Section 1834A(a)(1) of the Act requires applicable laboratories, 
beginning January 1, 2016, to report applicable information on CDLTs 
that are not ADLTs every 3 years, and every year for ADLTs, at a time 
specified by the Secretary. As discussed in section II.D.1., we are 
proposing that the data collection period during which applicable 
laboratories collect applicable information would be the calendar year 
immediately prior to the data reporting period. Thus, the data 
reporting period would occur each year for ADLTs, from January 1 
through March 31, and every third year, from January 1 through March 
31, for all other CDLTs (for example, 2016, 2019, 2022, etc.). We 
propose to establish these data reporting requirements in Sec.  
414.504(a) of the regulations.
    Section 1834A(a)(3)(A) of the Act requires applicable information 
to be the rate paid by each private payor for the test and the 
associated volume of such tests for each such payor during the data 
collection period. In addition, section 1834A(a)(6) of the Act 
specifies that, in the case where an applicable laboratory has more 
than one payment rate for the same payor for the same test or more than 
one payment rate for different payors for the same test, the applicable 
laboratory must report each such payment rate and the volume for the 
test at each such rate. Furthermore, section 1834A(a)(6) of the Act 
provides that, beginning January 1, 2019, the Secretary may establish 
rules to aggregate reporting, that is, permit applicable laboratories 
to combine the prices and volumes for individual tests; we understand 
this to mean that, absent rules set by the Secretary (in 2019 or 
later), applicable laboratories may not aggregate data by laboratory 
test in reporting applicable information. Taken together, these 
provisions indicate that an applicable laboratory must report 
applicable information for every test it performs for each private 
payor, including both the amounts paid and volume. This means, should a 
rate for a private payor change during the data collection period, an 
applicable laboratory would report both the old and new rates and the 
volume of tests associated with each rate. We realize the amount of 
applicable information could be voluminous for those applicable 
laboratories that offer a large number of tests. However, we believe 
the statute requires comprehensive reporting of applicable information 
so the Medicare CLFS rates accurately reflect the rates paid by private 
payors to laboratories. Our proposed definition of applicable 
information in Sec.  414.502 states that applicable information, with 
respect to each CDLT for a data collection period, includes each 
private payor rate and the associated volume of tests performed 
corresponding to each private payor rate, so our proposed requirement 
at Sec.  414.504(a) covers the requirement for applicable laboratories 
to report the private payor rate for every laboratory test it performs, 
and to account for the volume of tests furnished at each rate. This 
requirement means that an applicable laboratory that has more than one 
payment rate for the same payor for the same test, or more than one 
payment rate for different payors for the same test, must report each 
such payment rate and the volume for the test at each such rate.
    To minimize the reporting burden on applicable laboratories and to 
avoid collecting personally identifiable information, we would only 
require applicable laboratories to report the minimum information 
necessary to

[[Page 59401]]

enable us to set CLFS payment rates. We will specify the form and 
manner for reporting applicable information in guidance prior to the 
first data reporting period, but generally, in reporting applicable 
information, we will expect laboratories to report the specific HCPCS 
code associated with each laboratory test, the private payor rate or 
rates associated with the HCPCS code, and the volume of laboratory 
tests performed by the laboratory at each private payor rate. We would 
not permit applicable laboratories to report individual claims because 
claims include more information than we need to set payment rates and 
they contain personally identifiable information. We also would not 
permit applicable laboratories to report private payor names because 
section 1834A(a)(11) of the Act prohibits a payor from being identified 
on information reported by the applicable laboratory. Our guidance 
would reflect these instructions. Accordingly, we are proposing to 
include in our data reporting requirements at Sec.  414.504(b), that 
applicable information must be reported in the form and manner 
specified by CMS.
3. Data Reporting Requirements for New ADLTs
    Section 1834A(d)(1)(A) of the Act requires the payment amount for 
new ADLTs to be based on actual list charge for an ``initial period'' 
of 3 quarters, but does not specify when this initial period of 3 
quarters begins. We believe the initial period should start and end on 
the basis of a calendar quarter, so that the first day of the initial 
period would be the first day of a calendar quarter, and the last day 
of the initial period would be the last day of a calendar quarter (for 
example, January 1 and March 31, April 1 and June 30, July 1 and 
September 30, or October 1 and December 31). We are proposing this 
policy to be consistent with how applicable information would be 
reported for CDLTs (on the basis of a calendar year, that is, 4 
quarters of applicable information) and how CLFS payment rates would be 
updated (also on the basis of a calendar year). This consistency is 
important so that after the new ADLT initial period is over, all CLFS 
payment rates (for CDLTs and ADLTs) will be posted publicly at the same 
time. Further, CMS updates all of its payment systems on the basis of a 
calendar quarter, and we believe consistency with all other CMS data 
systems will facilitate implementation and updates to the CLFS. 
Beginning and ending the new ADLT initial period on the basis of a 
calendar quarter would also be consistent with average sales price 
reporting for Medicare Part B drugs under section 1847A of the Act and 
desirable for the reasons stated above. If we were to start the initial 
period during a calendar quarter, then the end of the Q2 (the time by 
which applicable laboratories must report applicable information for 
new ADLTs) would also occur during a calendar quarter, which would mean 
that applicable laboratories would be reporting applicable information 
for new ADLTs during a calendar quarter. Further, if an initial period 
of three quarters ends during a calendar quarter, CMS would have to 
begin paying for the ADLT using the methodology under section 1834A(b) 
of the Act during a calendar quarter. For these reasons, we propose to 
start the initial period on the first day of the first full calendar 
quarter following first day on which a new ADLT is performed. We 
propose to refer to the initial period for new ADLTs as the ``new ADLT 
initial period,'' and to codify the definition in Sec.  414.502.
    Section 1834A(d)(2) of the Act requires applicable laboratories to 
report applicable information for new ADLTs not later than the last day 
of the Q2 of the initial period. The applicable information will be 
used to determine the CLFS payment amount (using the weighted median 
methodology; see our discussion of the CDLT payment methodology in 
section II.H.1.) for a new ADLT after the new ADLT initial period. We 
propose to codify the reporting requirement for new ADLTs in Sec.  
414.504(a)(3).
    The following is an example of the reporting and payment schedule 
for a new ADLT: A new ADLT that is first performed by an applicable 
laboratory during the Q1 of 2017 (for example, February 4, 2017) would 
start its initial period on the first day of the Q2 of 2017 (April 1, 
2017). The new ADLT initial period would last for three full quarters, 
until the end of the Q4 of 2017 (December 31, 2017). The applicable 
laboratory would be required to report applicable information for the 
new ADLT by the end of the Q2 of the new ADLT initial period, which 
would be, in this example, the end of the Q3 of 2017 (September 30, 
2017). These data would be used to calculate the payment amount for the 
new ADLT, which would be applied after the end of the new ADLT initial 
period, which would be the Q1 2018 (January 1, 2018). This payment 
amount would last through the remainder of CY 2018. The new ADLT would 
then follow the annual reporting schedule for existing ADLTs, that is, 
CY 2017 applicable information would be reported between January 1, 
2018 through March 31, 2018, and the applicable information would then 
be used to establish the payment amount for the ADLT that takes effect 
on January 1, 2019.
    Table 2 illustrates the proposed data collection and reporting 
periods for a new ADLT using the above example.

----------------------------------------------------------------------------------------------------------------

    We welcome comments on these proposals and on how to make the data 
reporting process work as efficiently as possible.

E. Data Integrity

1. Penalties for Non-Reporting
    Section 1834A(a)(9)(A) of the Act authorizes the Secretary to apply 
a CMP if the Secretary determines that an applicable laboratory has 
failed to report, or has made a misrepresentation or omission in 
reporting, information under section 1834A(a) of the Act for a CDLT. In 
these cases, the Secretary may apply a CMP in an amount of up to 
$10,000 per day for each failure to report or each such 
misrepresentation or omission. Section 1834A(a)(9)(B) of the Act 
further provides that the provisions of section 1128A of the Act (other 
than subsections (a) and (b)) shall apply to a CMP under this paragraph 
in the same manner as they apply to a CMP or proceeding under section 
1128A(a) of the Act. Section 1128A of the Act governs CMPs that apply 
to all federal health care programs. Thus the provisions of section 
1128A of the Act (specifically sections 1128A(c) through 1128A(n) of 
the Act) apply to a CMP under section 1834A(a)(9) of the Act in

[[Page 59402]]

the same manner as they apply to a CMP or proceeding under section 
1128A(a) of the Act. We note that a similar provision is included in 
the law under section 1847A(d)(4) of the Act with regard to the 
reporting of average sales price by the manufacturer of a drug or 
biological. Given the similarity between sections 1834A(a)(9)(A) and 
1847A(d)(4) of the Act, we are proposing to adopt a provision in Sec.  
414.504(e) for implementing section 1834A(a)(9)(A) of the Act that is 
similar to Sec.  414.806, the regulation governing drug manufacturers' 
reporting of Part B drug prices under section 1847A(d)(4) of the Act. 
Following the final publication of this rule, we anticipate issuing 
guidance further clarifying these requirements.
2. Data Certification
    Section 1834A(a)(7) of the Act requires that an officer of each 
applicable laboratory must certify the accuracy and completeness of the 
reported information required by section 1834A(a) of the Act. We 
propose to implement this provision by requiring in Sec.  414.504(d) 
that the President, CEO, or CFO of an applicable laboratory or an 
individual who has been delegated authority to sign for, and who 
reports directly to, the laboratory's President, CEO, or CFO, must sign 
a certification statement and be responsible for assuring that the 
applicable information provided is accurate, complete, and truthful, 
and meets all the reporting parameters. We will specify the processes 
for certification in subregulatory guidance prior to January 1, 2016.

F. Confidentiality and Public Release of Limited Data

    Section 1834A(a)(10) of the Act addresses the confidentiality of 
the information disclosed by a laboratory under section 1834A(a) of the 
Act. Specifically, this paragraph provides that, notwithstanding any 
other provision of law, information disclosed by a laboratory under 
section 1834A(a) of the Act is confidential and must not be disclosed 
by the Secretary or a Medicare contractor in a form that discloses the 
identity of a specific payor or laboratory, or prices charged or 
payments made to any such laboratory, except as follows:
     As the Secretary determines to be necessary to carry out 
section 1834A of the Act;
     To permit the Comptroller General to review the 
information provided;
     To permit the Director of the Congressional Budget Office 
(CBO) to review the information provided; and
     To permit MedPAC to review the information provided.
    These confidentiality provisions apply to information disclosed by 
a laboratory under section 1834A(a) of the Act, the paragraph that 
addresses reporting of applicable information for purposes of 
establishing CLFS rates, and therefore we interpret these protections 
as applying to the applicable information that applicable laboratories 
report to CMS under proposed Sec.  414.504(a). We do not read section 
1834A(a)(10) of the Act as applying to other information laboratories 
may submit to CMS that does not constitute applicable information, for 
example, information regarding an applicable laboratory's business 
structure, such as its associated NPI entities, or information 
submitted in connection with an application for ADLT status under 
section 1834A(d) of the Act (including evidence of a laboratory's 
empirically derived algorithms and how the test provides new clinical 
diagnostic information that cannot be obtained from any other test or 
combination of tests).
    As we discuss in more detail in section II.H.1., we will use the 
applicable information reported under proposed Sec.  414.504 to set 
CLFS payment rates, and intend to make available to the public a list 
of test codes and the CLFS payment rates associated with those codes, 
which is the same CLFS information we currently make available. This 
information would not reveal the identity of a specific payor or 
laboratory, or prices charged or payments made to a specific laboratory 
(except as noted below), and thus, we believe continuing to publish 
this limited information would allow us to be compliant with section 
1834A(a)(10) of the Act while continuing to provide necessary 
information to the public on CLFS payment amounts.
    As noted above, section 1834A(a)(10) of the Act lists four 
instances when the prohibition on disclosing information reported by 
laboratories under section 1834A(a) of the Act would not apply, the 
first being when the Secretary determines disclosure is necessary to 
carry out section 1834A of the Act. We believe certain disclosures will 
be necessary for CMS to administer and enforce the new Medicare payment 
system for CDLTs. For example, it may be necessary to disclose to the 
HHS Office of Inspector General confidential data needed to conduct an 
audit, evaluation, or investigation or to assess a CMP, or to disclose 
to other law enforcement entities such as the Department of Justice 
confidential data needed to conduct law enforcement activities. 
Therefore, we are proposing to add those entities to the list of 
entities in Sec.  414.504(f) to which CMS may disclose applicable 
information that is otherwise confidential. Additionally, there may be 
other circumstances that require the Secretary to disclose confidential 
information regarding the identity of a specific laboratory or private 
payor. In the event we determine it necessary to disclose confidential 
information for other circumstances, we would notify the public of the 
reasons through a Federal Register announcement or via a CMS Web site 
publication.
    Also, we believe that codes and associated CLFS payment rates 
published for ADLTs may indirectly disclose the identity of the 
specific laboratories selling those tests, and, for new ADLTs, payments 
made to those laboratories. That is because, as explained in section 
II.C. of this proposed rule, ADLTs are offered and furnished only by a 
single laboratory. Thus, we believe publishing the test code and 
associated CLFS payment rate for an ADLT would indirectly reveal the 
identity of the laboratory because only the single laboratory is 
offering and furnishing that test. Moreover, because Medicare will pay 
actual list charge for a new ADLT during the new ADLT initial period, 
publishing the test code and associated CLFS rate for a new ADLT would, 
we believe, reveal the payments made to the laboratory offering and 
furnishing that test. We believe section 1834A(a)(10)(A) of the Act 
authorizes us to publish the test codes and associated CLFS payment 
rates for ADLTs because we need to publish the CLFS rates for ADLTs and 
we do not believe we can do so without indirectly revealing ADLT 
laboratory identities and payments made to those laboratories. However, 
because the actual list charge for a new ADLT would already be publicly 
available, we do not believe laboratories will be harmed by our 
publishing the CLFS rates for new ADLTs. We will not publish 
information that directly discloses a laboratory's identity, but we 
cannot prevent the public from associating CLFS payment information for 
an ADLT to the single laboratory offering and furnishing the test.
    Section 1834A(a)(10) of the Act also prohibits a Medicare 
contractor from disclosing information under section 1834A(a) of the 
Act in a form that reveals the identity of a specific payor or 
laboratory, or prices charged or payments made to any such laboratory. 
We do not expect this prohibition to be problematic as applicable 
laboratories will be reporting applicable information

[[Page 59403]]

to CMS and not the MACs. When a MAC sets rates under our new policies, 
we would expect the MAC will follow its current practice for pricing 
when developing a local payment rate for an item or service that does 
not have a national payment rate, which is, it would only disclose 
pricing information to the extent that it needs to process and pay a 
claim.
    We propose to implement the confidentiality requirements of section 
1834A(a)(10) of the Act in Sec.  414.504(f).

G. Coding for Certain Clinical Diagnostic Laboratory Tests (CDLTs) on 
the CLFS

    Section 1834A(e) of the Act includes coding requirements for 
certain new and existing ADLTs and laboratory tests that are cleared or 
approved by the FDA. In this section, we describe our current coding 
system for the CLFS and how we propose to utilize aspects of this 
system to implement the coding provisions in section 1834A(e) of the 
Act.
1. Background
    Currently, new tests on the CLFS receive HCPCS level I codes (CPT) 
from the American Medical Association (AMA). The CPT is a uniform 
coding system consisting of descriptive terms and codes that are used 
primarily to identify medical services and procedures furnished by 
physicians, suppliers, and other health care professionals. Decisions 
regarding the addition, deletion, or revision of CPT codes are made by 
the AMA, and published and updated annually by the AMA. Level II of the 
HCPCS is a standardized coding system used primarily to identify 
products, supplies, and services not included in the CPT codes, such as 
ambulance services and durable medical equipment, prosthetics, 
orthotics and supplies (DMEPOS). Because Medicare and other insurers 
cover a variety of services, supplies, and equipment that are not 
identified by CPT codes, the HCPCS level II codes were established for 
submitting claims for these items.
    Within CMS, the CMS HCPCS Workgroup, which is comprised of 
representatives of major components of CMS and consultants from 
pertinent Federal agencies, is responsible for all revisions, 
deletions, and addition to the HCPCS level II codes. As part of its 
deliberations, the CMS HCPCS Workgroup may develop temporary and 
permanent national alpha-numeric HCPCS level II codes. Permanent HCPCS 
level II codes are established and updated annually, whereas temporary 
HCPCS level II codes are established and updated on a quarterly basis. 
Temporary codes are useful for meeting, in a short time frame, the 
national program operational needs of a particular insurer that are not 
addressed by an already existing national code. For example, Medicare 
may need additional codes before the next annual HCPCS update to 
implement newly issued coverage policies or legislative requirements.
    Temporary HCPCS level II codes do not have established expiration 
dates, however, a temporary code may be replaced by a CPT code, or the 
CMS HCPCS Workgroup may decide to replace a temporary code with a 
permanent HCPCS level II code. For example, a laboratory may request a 
code for a test in the middle of a year. Because permanent codes are 
assigned only once a year, the CMS HCPCS Workgroup may assign the 
laboratory test a temporary HCPCS level II code. The temporary code may 
be used indefinitely or until a permanent code is assigned to the test. 
Whenever the CMS HCPCS Workgroup establishes a permanent code to 
replace a temporary code, the temporary code is cross-referenced to the 
new permanent code and deleted.
    ``G codes'' are temporary HCPCS level II codes used by CMS to 
identify professional health care procedures and services, including 
laboratory tests, that would otherwise be identified by a CPT code, but 
for which there is no CPT code. CMS has used G codes for laboratory 
tests that do not have CPT codes but for which CMS makes payment, or in 
situations where CMS wants to treat the codes differently from the CPT 
code descriptor for Medicare payment purposes.
2. Coding Under PAMA
    Section 1834A(e) of the Act includes three provisions that relate 
to coding: (a) Temporary codes for certain new tests; (b) coding for 
existing tests; and (c) establishment of unique identifiers for certain 
tests. The effect of section 1834A(e) of the Act is to require the 
Secretary to establish codes, whereas prior to the enactment of PAMA, 
the Secretary had discretion, but was not required to do so. Before we 
discuss each of the three provisions, we address several specific 
references in the statute that we believe need clarification.
    In the three coding provisions, the statute requires us to 
``adopt,'' ``assign,'' and ``establish'' codes or identifiers. We 
believe those terms are interchangeable. There is no practical 
difference between them for purposes of CMS's obligation under section 
1834A(e) of the Act, which is, essentially, to ensure that certain 
laboratory tests can be identified by a HCPCS code, or in the case of 
section 1834A(e)(3) of the Act, a unique identifier. The statute also 
refers to ``new laboratory tests'' and ``existing clinical diagnostic 
laboratory test[s]'' in sections 1834A(e)(1)(A) and (2), respectively. 
We believe new laboratory tests here refers to CDLTs (that are cleared 
or approved by the FDA) paid under the CLFS on or after January 1, 
2017, and existing CDLTs refers to CDLTs (that are approved or cleared 
by the FDA) paid under the CLFS prior to that date.
a. Temporary Codes for Certain New Tests
    Section 1834A(e)(1)(A) of the Act requires the Secretary to adopt 
temporary HCPCS codes to identify new ADLTs and new laboratory tests 
that are cleared or approved by the FDA. In section II.C.1. of this 
proposed rule, we proposed a definition for new ADLTs, and in section 
II.C.2., we discuss what it means for a laboratory test to be cleared 
or approved by the FDA. We are applying those interpretations here. We 
understand the statute to be requiring us to adopt temporary HCPCS 
level II codes for these two types of laboratory tests if they have not 
already been assigned a HCPCS code. Therefore, we would utilize the 
existing HCPCS coding process for these tests. This means, if a new 
ADLT or a new CDLT that is FDA cleared or approved is not already 
assigned a CPT code or HCPCS level II code, we would assign a G code to 
the test. The statute further directs that the temporary code be 
effective for up to 2 years until a permanent HCPCS code is 
established, although the statute permits the Secretary to extend the 
length of time as appropriate. Therefore, any G code that we adopt 
under this provision would be effective for up to two years, unless we 
believe it is appropriate to continue to use the G code. For instance, 
we may create a G code to describe a test for prostate specific antigen 
(PSA) that may be covered by Medicare under sections 1861(s)(2)(P) and 
1861(oo)(2)(B) of the Act as a prostate cancer screening test. At the 
end of 2 years, if the AMA has not created a CPT code to describe that 
test but Medicare continues to have a need to pay for the test 
described by the G code, we would continue to use the G code.
b. Coding and Publication of Payment Rates for Existing Tests
    Section 1834A(e)(2) of the Act stipulates that not later than 
January 1, 2016, for each existing ADLT and each existing CDLT that is 
cleared or approved by the FDA for which

[[Page 59404]]

payment is made under Medicare Part B as of PAMA's enactment date 
(April 1, 2014), if such test has not already been assigned a unique 
HCPCS code, the Secretary shall (1) assign a unique HCPCS code for the 
test and (2) publicly report the payment rate for the test.
    As with the requirement for us to adopt codes for certain new tests 
under section 1834A(e)(1) of the Act, we believe our existing coding 
process is consistent with the requirements of section 1834A(e)(2) of 
the Act. Accordingly, we would utilize the existing HCPCS coding 
process for these tests, meaning, if an existing ADLT or existing CDLT 
is not already assigned a CPT code or a HCPCS level II code, we would 
assign a G code to the test.
    One aspect of section 1834A(e)(2) of the Act (applying to existing 
tests) that is different than section 1834A(e)(1) of the Act (applying 
to certain new tests) is the requirement for us to assign a ``unique'' 
HCPCS code. We understand a unique HCPCS code to describe only a single 
test. An ADLT is a single test, so each existing ADLT would be assigned 
its own G code. However, it is possible that one HCPCS code is used to 
describe more than one existing CDLT that is cleared or approved by the 
FDA. For instance, we understand there are different versions of 
laboratory tests for the Kirsten rat sarcoma viral oncogene homolog 
(KRAS)--one version that is FDA-approved and others that are not FDA 
cleared or approved. Currently, the same HCPCS code is used for both 
the FDA-approved laboratory test for KRAS and the non-FDA cleared or 
approved versions of the test. Thus, the current HCPCS code is not 
unique in describing only the FDA-approved version of the KRAS test. 
Under section 1834A(e)(2) of the Act, we are required to ensure that 
FDA cleared or approved versions of the KRAS test are assigned their 
own unique codes.
    Section 1834A(e)(2)(B) of the Act requires CMS to publicly report 
the payment rate for the existing ADLT or test that is cleared or 
approved by the FDA by January 1, 2016. It is possible there are 
existing ADLTs or CDLTs cleared or approved by the FDA that are 
currently being priced under our existing regulations using 
crosswalking or gapfilling. For instance, some tests are currently 
being priced using gapfilling (see https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/ClinicalLabFeeSched/Downloads/CY2015-CLFS-Codes-Final-Determinations.pdf). If any of the tests that are 
currently being priced using gapfilling fall within the category of 
section 1834A(e)(2) existing laboratory tests, we would be able to 
report the payment rate for them by January 1, 2016. There may be other 
tests in the category of section 1834A(e)(2) existing laboratory tests 
that are currently being priced for January 1, 2016, and that are 
already being paid by the MACs. (See https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/ClinicalLabFeeSched/Downloads/Clinical-Lab-Codes-for-CY-2016.pdf for a list of codes discussed at the 
Annual Public Meeting on July 16, 2015 that we are currently in the 
process of pricing for January 1, 2016.) As these tests are already 
being paid by MACs, we would be able to publicly report their payment 
amounts by January 1, 2016.
    To fulfill the requirement to publicly report payment rates, we 
will include the codes and payment amounts on the electronic CLFS 
payment file that we make available on the CMS Web site prior to 
January 1, 2016. We are currently considering how we would present the 
information. We expect to provide a separate field with a special 
identifier indicating when a HCPCS code uniquely describes an existing 
laboratory test, although we may separately identify those codes that 
uniquely identify an existing test in separate documentation describing 
the file.
c. Establishing Unique Identifiers for Certain Tests
    Section 1834A(e)(3) of the Act requires the establishment of a 
unique identifier for certain tests. Specifically, section 1834A(e)(3) 
of the Act provides that, for purposes of tracking and monitoring, if a 
laboratory or a manufacturer requests a unique identifier for an ADLT 
or a laboratory test that is cleared or approved by the FDA, the 
Secretary shall utilize a means to uniquely track such test through a 
mechanism such as a HCPCS code or modifier. Section 1834A(e)(3) of the 
Act applies only to those laboratory tests that are addressed by 
sections 1834A(e)(1) and (2) of the Act, that is, new and existing 
ADLTs and new and existing CDLTs that are cleared or approved by the 
FDA.
    The statute does not define ``tracking and monitoring.'' However, 
in the context of a health insurance program like Medicare, tracking 
and monitoring would typically be associated with enabling or 
facilitating the obtaining of information included on a Medicare claim 
for payment to observe such factors as: Overall utilization of a given 
service; regional utilization of the service; where a service was 
provided (for example, office, laboratory, hospital); who is billing 
for the service (for example, physician, laboratory, other supplier); 
which beneficiary received the service; and characteristics of the 
beneficiary receiving the service (for example, male/female, age, 
diagnosis). As the HCPCS code is the fundamental variable used to 
identify an item or service, and can serve as the means to uniquely 
track and monitor many various aspects of a laboratory test, we believe 
the requirements of this section will be met by the existing HCPCS 
coding process. Therefore, we intend to implement section 1834A(e)(3) 
of the Act using our current HCPCS coding system. If a laboratory or 
manufacturer specifically requests from us a unique identifier for 
tracking and monitoring an ADLT or an FDA cleared or approved or 
cleared CDLT, we would assign it a unique HCPCS code if it does not 
already have one.

H. Payment Methodology

1. Calculation of Weighted Median
    Section 1834A(b) of the Act establishes a new methodology for 
determining Medicare payment amounts for CDLTs on the CLFS. Section 
1834A(b)(1)(A) of the Act establishes the general requirement that the 
Medicare payment amount for a CDLT furnished on or after January 1, 
2017, shall be equal to the weighted median determined for the test for 
the most recent data collection period. Section 1834A(b)(2) of the Act 
requires the Secretary to calculate a weighted median for each 
laboratory test for which information is reported for the data 
collection period by arraying the distribution of all private payor 
rates reported for the period for each test weighted by volume for each 
private payor and each laboratory. As discussed later in this section, 
the statute includes special payment requirements for new ADLTs and new 
CDLTs that are not ADLTs.
    To illustrate how we propose to calculate the weighted median for 
CDLTs, we are providing examples of several different scenarios. These 
examples are meant to show how we plan to determine the weighted median 
and not to be exhaustive of every possible pricing scenario. As 
depicted in Table 3, suppose that applicable laboratories report the 
following private payor rate and volume information for three different 
CDLTs.

--------------------------------------------------------------------------------------------------------------------------------------------------------

    In this example, there are five different private payor rates for 
each test. Table 3 is shown again as Table 4 with each test arrayed by 
order of the lowest to highest private payor rate, with each private 
payor rate appearing one time only so as to not reflect volume 
weighting.

    With five different private payor rates for each test, the 
unweighted median is the middle value or the third line in the table 
where there are an equal number of private payor rates listed above and 
below the third line in the table. The unweighted median private payor 
rate for each test would be:
     Test 1 = $5.00
     Test 2 = $23.50
     Test 3 = $41.00
    These results are obtained by arraying the distribution of all 
private payor rates reported for the period for each test without 
regard to the volume reported for each private payor and each 
laboratory. To obtain the weighted median, we would do a similar array 
to the one in Table 4 except we would list each distinct private payor 
rate repeatedly by the same number of times as its volume. This is 
illustrated for Test 1 in Table 5.

    Thus, for Test 1, the array would show the lowest private payor 
rate of $2.50 five thousand times. The ellipsis (``. . .'') represents 
the continuation of the sequence between lines 2 and 4,999. The next 
private payor rate in the sequence ($4.00) would appear on line 5,001 
and would be listed 3,000 times until we get to line 8,000. This 
process would continue with the remaining private payor rates listed as 
many times as the associated volumes, with the continuing sequence 
illustrated by ellipses. Continuing the array, the next highest private 
payor rate in the sequence would be: $5.00 listed 1,000 times; $6.00 
listed 900 times; and $9.00 listed 1,100 times. The total number of 
lines in the array would be 11,000, as that is the total volume for 
Test 1 furnished by the five applicable laboratories. Because the total 
volume for Test 1 is 11,000, the weighted median private payor rate 
would be the average of the 5,500th and 5,501st entry, which would be 
$4.00.
    Repeating this process for Test 2 (see Table 6), the total volume 
for Test 2 is 7,600 units; therefore, the weighted median private payor 
rate would be the average of the 3,800th and 3,801st entry, which would 
be $18.00.

------------------------------------------------------------------------

    For Test 3 (see Table 7), the total volume is 3,550 units; 
therefore, the weighted median private payor rate would be the average 
of the 1,775th and 1,776th entry, which would be $41.00.

    In this example, weighting changed the median private payor rate 
from $5.00 to $4.00 for Test 1, from $23.50 to $18.00 for Test 2, and 
resulted in no

[[Page 59406]]

change ($41.00 both unweighted and weighted) for Test 3.
    For simplicity, the above example shows only one private payor rate 
per test. We expect laboratories commonly have multiple private payor 
rates for each CDLT they perform. For each test performed by applicable 
laboratories having multiple private payor rates, we would use the same 
process shown above, irrespective of how many different private payor 
rates there are for a given test. In other words, we would list each 
private payor rate and its volume at that private payor rate, and 
determine the median as we did above for each payor and each 
laboratory, and then compute the volume-weighted median rate. The 
following example in Table 8 illustrates how we propose to calculate 
the weighted median rate for a test under this scenario:

                                                                     Table 8--Test 4

    To calculate the weighted median for Test 4, we would array all 
private payor rates, listed the number of times for each respective 
test's volume, and then determine the median value (as illustrated in 
Table 9).

6.00....................................................               5
6.00....................................................               5
------------------------------------------------------------------------

    The total volume for Test 4 is 195. Therefore, the median value 
would be at the 98th entry, which would be 4.75. We are proposing to 
describe this process in Sec.  414.507(b).
    Section 1834A(b)(1)(B) of the Act states that the Medicare payment 
amounts established under section 1834A of the Act shall apply to a 
CDLT furnished by a hospital laboratory if such test is paid for 
separately, and not as part of a bundled payment under section 1833(t) 
of the Act (the statutory section pertaining to the OPPS). In CY 2014, 
we finalized a policy to package certain CDLTs in the OPPS (78 FR 74939 
through 74942 and 42 CFR 419.2(b)(17)). Under current policy, certain 
CDLTs that are listed on the CLFS are packaged in the OPPS as integral, 
ancillary, supportive, dependent, or adjunctive to the primary service 
or services provided in the hospital outpatient setting on the same 
date of service as the laboratory test. Specifically, we conditionally 
package laboratory tests and only pay separately for a laboratory test 
when (1) it is the only service provided to a beneficiary on a given 
date of service or (2) it is conducted on the same date of service as 
the primary service, but is ordered for a different purpose than the 
primary service and ordered by a practitioner different than the 
practitioner who ordered the other OPPS services. Also excluded from 
this conditional packaging policy are molecular pathology tests 
described by CPT codes in the ranges of 81200 through 81383, 81400 
through 81408, and 81479 (78 FR 74939 through 74942). When laboratory 
tests are not packaged under the OPPS and are listed on the CLFS, they 
are paid at the CLFS payment rates outside the OPPS under Medicare Part 
B. Section 1834A(b)(1)(B) of the Act would require us to pay the CLFS 
payment amount determined under section 1834A(b)(1)(B) of the Act for 
CDLTs that are provided in the hospital outpatient department and not 
packaged into Medicare's OPPS payment. This policy would apply to any 
tests currently paid separately in the hospital outpatient department 
or in the future if there are any changes to OPPS packaging policy.\2\ 
As these are payment policies that pertain to the OPPS, we will 
implement them in OPPS annual rulemaking.
---------------------------------------------------------------------------

    \2\ For the CY 2016 OPPS proposed rule, we have proposed changes 
to the packaging policy described above. See 80 FR 39235 for more 
information.
---------------------------------------------------------------------------

    Next, section 1834A(b)(4)(A) of the Act states that the Medicare 
payment amounts under section 1834A(b) shall continue to apply until 
the year following the next data collection period. We propose to 
implement this requirement in proposed Sec.  414.507(a) by stating that 
each payment rate will be in effect for a period of 1 calendar year for 
ADLTs and 3 calendar years for all other CDLTs, until the year 
following the next data collection period.
    Section 1834A(b)(4)(B) of the Act states that the Medicare payment 
amounts under section 1834A of the Act shall not be subject to any 
adjustment (including any geographic adjustment, budget neutrality 
adjustment, annual update, or other adjustment). As discussed 
previously in this section, the new payment methodology for CDLTs 
established under section 1834A(b) of the Act will apply to all tests 
furnished on or after January 1, 2017, and replace the current 
methodology for calculating Medicare payment amounts for CDLTs under 
sections 1833(a), (b), and (h) of the Act, including the annual updates 
for inflation based on the percentage change in the CPI-U and reduction 
by a multi-factor productivity adjustment (see section 1833(h)(2)(A) of 
the Act). We believe section 1834A(b)(4)(B) of the Act is clear that 
Congress intended there be no annual update adjustment for tests paid 
under section 1834A of the Act. Therefore, we are proposing to include 
in Sec.  414.507(c) that the payment amounts established under this 
section are not subject to any adjustment, such as any geographic, 
budget neutrality, annual update, or other adjustment.
2. Phased-In Payment Reduction
    Section 1834A(b)(3) of the Act limits the reduction in payment 
amounts that may result from implementation of the new payment 
methodology under section 1834A(b) of the Act within the first 6 years. 
Specifically, section 1834A(b)(3)(A) of the Act states that the payment 
amounts determined for a CDLT for a year cannot be reduced by more than 
the applicable percent from the preceding year for each of 2017 through 
2022. Under section

[[Page 59407]]

1834A(b)(3)(B) of the Act, the applicable percent is 10 percent for 
each of 2017 through 2019, and 15 percent for each of 2020 through 
2022. These provisions do not apply to new ADLTs, or new CDLTs that are 
not ADLTs (defined in Sec.  414.502 and discussed in sections II.H.3. 
and H.6. of this proposed rule).
    For example, if a test that is not a new ADLT or new CDLT has a CY 
2016 Medicare payment amount of $20.00, the maximum reduction in the 
Medicare payment amount for CY 2017 is 10 percent, or $2. Following the 
CY 2016 data reporting period, CMS calculates a weighted median of 
$15.00 (a reduction of 25 percent from a Medicare payment amount of 
$20.00) based on the applicable information reported for the test. 
Because the maximum payment reduction permitted under the statute for 
2017 is 10 percent, the Medicare payment amount for CY 2017 will be 
$18.00 ($20.00 minus $2.00). The following year, a 10 percent reduction 
from the CY 2017 payment of $18.00 would equal $1.80, lowering the 
total Medicare payment amount to $16.20 for CY 2018. As a second 
example, if a test that is not a new ADLT or new CDLT has a CY 2016 
Medicare payment amount of $17.00, the maximum reduction for CY 2017 is 
10 percent or $1.70. Following the CY 2016 data reporting period, CMS 
calculates a weighted median of $15.00 (a reduction of 11.8 percent 
from the CY 2016 Medicare payment amount of $17). Because the maximum 
reduction is 10 percent, the Medicare payment amount for CY 2017 will 
be $15.30 or the maximum allowed reduction of $1.70 from the preceding 
year's (CY 2016) Medicare payment amount of $17.00. The following year 
(CY 2018), the Medicare payment amount will be reduced to $15.00, or 
$0.30 less, which is less than a 10 percent reduction from the prior 
year's (CY 2017) Medicare payment amount of $15.30. We believe applying 
the maximum applicable percentage reduction from the prior year's 
Medicare payment amount, rather than from the weighted median rate for 
CY 2016, is most consistent with the statute's mandate that the 
reduction ``for the year'' (that is, the calendar year) not be 
``greater than the applicable percent . . . of the amount of payment 
for the test for the preceding year.''
    To apply the phase-in reduction provisions beginning in CY 2017, we 
must look at the CLFS rates established for CY 2016 under the payment 
methodology set forth in sections 1833(a), (b), and (h) of the Act. As 
discussed in section II.B.1. of this proposed rule, CDLTs furnished on 
or after July 1, 1984, and before January 1, 2017, in a physician's 
office, by an independent laboratory, or, in limited circumstances, by 
a hospital laboratory for its outpatients or non-patients, are paid 
under the Medicare CLFS, with certain exceptions. Payment is the lesser 
of:
     The amount billed;
     The state or local fee schedule amount established by 
Medicare contractors; or
     An NLA, which is a percentage of the median of all the 
state and local fee schedules.
    The NLA is 74 percent of the median of all local Medicare payment 
amounts for tests for which the NLA was established before January 1, 
2001. The NLA is 100 percent of the median of the local fee schedule 
amount for tests for which the NLA was first established on or after 
January 1, 2001 (see section 1833(h)(4)(B)(viii) of the Act). Medicare 
typically pays either the lower of the local fee schedule amount or the 
NLA, as it uncommon for the amount billed to be less than either of 
these amounts. As the local fee schedule amount may be lower than the 
NLA, Medicare payment amounts for CDLTs are not uniform across the 
nation. Thus, we must decide which CY 2016 CLFS payment amounts to 
consider--the lower of the local fee schedule amount or the NLA, or 
just the NLA--when applying the phase-in reduction provisions to the 
CLFS rates for CY 2017. Under option 1, we would apply the 10 percent 
reduction limitation to the lower of the NLA or the local fee schedule 
amount. This option would retain some of the features of the current 
payment methodology under sections 1833(a), (b), and (h) of the Act 
and, we believe, would be the most consistent with the requirement in 
section 1834A(b)(3)(A) of the Act to apply the applicable percentage 
reduction limitation to the ``amount of payment for the test'' for the 
preceding year. As noted above, for each of CY 2018 through 2022, we 
would apply the applicable percentage reduction limitation to the 
Medicare payment amount for the preceding year. Under this option, 
though, the Medicare payment amounts may be local fee schedule amounts, 
so there could continue to be regional variation in the Medicare 
payment amounts for CDLTs.
    Alternatively, under option 2, we would consider only the NLAs for 
CY 2016 when applying the 10 percent reduction limitation. This option 
would eliminate the regional variation in Medicare payment amounts for 
CDLTs, and, we believe, would be more consistent with section 
1834A(b)(4)(B) of the Act, which, as noted above, prohibits the 
application of any adjustments to CLFS payment amounts determined under 
section 1834A of the Act, including any geographic adjustments.
    We are proposing option 2 (NLAs only) for purposes of applying the 
10 percent reduction limit to CY 2017 payment amounts because we 
believe the statute intends CLFS rates to be uniform nationwide, which 
is why it precludes any geographic adjustment. In other words, we are 
proposing that if the weighted median calculated for a CDLT based on 
applicable information for CY 2017 would be more than 10 percent less 
than the CY 2016 NLA for that test, we would establish a Medicare 
payment amount for CY 2017 that is no less than 90 percent of the NLA 
(that is, no more than a 10 percent reduction). For each of CY 2018 
through 2022, we would apply the applicable percentage reduction 
limitation to the Medicare payment amount for the preceding year.
    We are proposing to codify the phase-in reduction provisions in 
Sec.  414.507(d) to specify that for years 2017 through 2022, the 
payment rates established under this section for each CDLT that is not 
a new ADLT or new CDLT, may not be reduced by more than the following 
amounts for--
     2017--10 percent of the NLA for the test in 2016.
     2018--10 percent of the payment rate established in 2017.
     2019--10 percent of the payment rate established in 2018.
     2020--15 percent of the payment rate established in 2019.
     2021--15 percent of the payment rate established in 2020.
     2022--15 percent of the payment rate established in 2021.
    Table 10 illustrates the phase-in reduction for the two 
hypothetical examples presented above:

3. Payment for New ADLTs
    Section 1834A(d)(1)(A) of the Act provides that the payment amount 
for a new ADLT shall be based on the actual list charge for the 
laboratory test during an initial period of 3 quarters. Section 
1834A(d)(2) of the Act requires applicable laboratories to report 
applicable information for a new ADLT not later than the last day of 
the Q2 of the initial period. Section 1834A(d)(3) of the Act requires 
the Secretary to use the weighted median methodology under subsection 
(b) to establish Medicare payment rates for new ADLTs after the initial 
period. Under section 1834A(d)(3) of the Act, such payment rates 
continue to apply until the year following the next data collection 
period.
    In section II.D.3. of this proposed rule, we discuss our proposal 
to require the initial period, which we propose to call the ``new ADLT 
initial period,'' to begin on the first day of the first full calendar 
quarter following the first day on which a new ADLT is performed. In 
accordance with section 1834A(d)(1)(A) of the Act, we are proposing 
that the payment amount for the new ADLT will equal the actual list 
charge, as defined below, during the new ADLT initial period. 
Accordingly, we propose to codify Sec.  414.522(a)(1) to specify the 
payment rate for a new ADLT during the new ADLT initial period is equal 
to its actual list charge.
    Section 1834A(d)(1)(B) of the Act states that actual list charge 
means the publicly available rate on the first day at which the test is 
available for purchase by a private payor for a laboratory test. We 
believe the ``publicly available rate'' is the amount charged for an 
ADLT that is readily accessible in such forums as a company Web site, 
test registry, or price listing, to anyone seeking to know how much a 
patient who does not have the benefit of a negotiated rate would pay 
for the test. This interpretation of publicly available rate is 
distinguishable from a private payor rate in that the former is readily 
available to a consumer, while the latter may be negotiated between a 
private payor and a laboratory and is not readily available to a 
consumer. We recognize there may be more than one publicly available 
rate, in which case we believe the lowest rate should be the actual 
list charge amount so that Medicare is not paying more than the lowest 
rate that is publicly available to any consumer. We would define 
publicly available rate in Sec.  414.502 as the lowest amount charged 
for an ADLT that is readily accessible in such forums as a company Web 
site, test registry, or price listing, to anyone seeking to know how 
much a patient who does not have the benefit of a negotiated rate would 
pay for the test.
    In our view, the first day a new ADLT is available for purchase by 
a private payor is the first day an ADLT is offered to a patient who is 
covered by private insurance. The statutory phrase ``available for 
purchase'' suggests to us that the test only has to be available to 
patients who have private insurance even if the test has not actually 
been performed yet by the laboratory. That is, it is the first day the 
new ADLT is obtainable by a patient, or marketed to the public as a 
test that a patient can receive, even if the test has not yet been 
performed on that date. We propose to incorporate this interpretation 
into our proposed definition of actual list charge in Sec.  414.502 to 
specify actual list charge is the publicly available rate on the first 
day the new ADLT is obtainable by a patient who is covered by private 
insurance, or marketed to the public as a test a patient can receive, 
even if the test has not yet been performed on that date.
    Because we cannot easily know the first date on which a new ADLT is 
performed or the actual list charge amount for a new ADLT, we would 
require the laboratory seeking ADLT status for its test to inform us of 
both the date the test is first performed and the actual list charge 
amount. Accordingly, we are proposing in Sec.  414.504(c), that, in its 
new ADLT application, the laboratory seeking new ADLT status for its 
test must attest to the actual list charge and the date the new ADLT is 
first performed. We will outline the new ADLT application process in 
detail in subregulatory guidance prior to January 1, 2017.
    Because the new ADLT initial period starts on the first day of the 
next calendar quarter following the first day on which a new ADLT is 
performed, there will be a span of time between when the test is first 
performed and when the test is paid the actual list charge amount. We 
need to establish a payment amount for the test during that span of 
time. Similar to how CMS pays for a test under the PFS, the CLFS, or 
other payment systems, for a service that does not yet have a national 
payment amount, the MAC would work with a laboratory to develop a 
payment rate for a new ADLT for the period of time before CMS pays at 
actual list charge. For example, if an ADLT is first performed on 
February 4, 2017, the new ADLT initial period would begin on April 1, 
2017. While the new ADLT would be paid the actual list charge amount 
from April 1 through December 31, 2017, the MAC would determine the 
payment amount for the test from February 4 through March 31, 2017, as 
it does currently for tests that need to be paid prior to having a 
national payment amount. We propose to reflect the payment amount for a 
new ADLT prior to the new ADLT initial period at Sec.  414.522(a)(2) to 
specify the payment amount is determined by the MAC based on 
information provided by the laboratory seeking new ADLT status for its 
laboratory test.
    According to section 1834A(d)(3) of the Act, the weighted median 
methodology used to calculate the payment amount for CDLTs that are not 
new ADLTs will be used to establish the payment amount for a new ADLT 
after the new ADLT initial period; the payment amount will be based on 
applicable information reported by an applicable laboratory before the 
last day of the second quarter of the new ADLT initial period, per 
section 1834A(d)(2) of the Act. We propose to codify these provisions 
in Sec.  414.522(b) as follows: After the new ADLT initial period, the 
payment rate for a new ADLT is equal to the weighted median established 
under the payment methodology described in Sec.  414.507(b).
    The payment rate based on the first 2 quarters of the new ADLT 
initial period will continue to apply until the year following the next 
data collection period, per section 1834A(d)(3) of the Act. The 
following is an example of how the various time frames for new ADLT 
payment rates would work. If the first day a new ADLT is available for 
purchase by a private payor is in the middle of Q1 of 2017, the new 
ADLT

[[Page 59409]]

initial period would begin on the first day of Q2 of CY 2017. The test 
would be paid actual list charge through the end of Q4 of CY 2017. The 
applicable laboratory that furnishes the test would collect applicable 
information in Q2 and Q3 of CY 2017, and report it to CMS by the last 
day of Q3 of CY 2017. CMS would calculate a weighted median based on 
that applicable information and establish a payment rate that would be 
in effect from January 1, 2018, through the end of 2018. The applicable 
laboratory would report applicable information from the CY 2017 data 
collection period to CMS during the January through March data 
reporting period in 2018, which would be used to establish the payment 
rate that would go into effect on January 1, 2019.
4. Recoupment of Payment for New ADLTs if Actual List Charge Exceeds 
Market Rate
    Section 1834A(d)(4) of the Act requires that after the new ADLT 
initial period, if the Medicare payment amount during the new ADLT 
initial period (that is, the actual list charge) is more than 130 
percent of the Medicare payment amount determined using the weighted 
median of private payor rates that is applicable after the new ADLT 
initial period, the Secretary shall recoup the difference between the 
Medicare payment amounts during the initial period and the Medicare 
payment amount based on the weighted median of private payor rates. We 
believe the statute is directing the Secretary to recoup the entire 
amount of the difference between the Medicare payment amount during the 
new ADLT initial period and the Medicare payment amount based on the 
weighted median of private payor rates--not the difference between the 
Medicare payment amount during the initial period and 130 percent of 
the weighted median rate. For example, if the Medicare payment amount 
using actual list charge is $150 during the new ADLT initial period and 
the weighted median rate is $100, the Medicare payment amount is 150 
percent of the Medicare payment amount based on the weighted median 
rate. We believe the statute is directing the Secretary to use 130 
percent as the threshold for invoking the recoupment provision but once 
invoked, collect the entire amount of the difference in Medicare 
payment amounts ($50 in this example).
    The statute refers to ``Such amounts'' which means the Medicare 
payment amount based on actual list charge and the Medicare payment 
amount based on the weighted median rate. The statute directs 
recoupment of the full amount of that difference as the 130 percent is 
only being used in making the threshold determination of whether the 
recoupment provision will apply. For this reason, we are proposing at 
Sec.  414.522(c) to specify that if the difference between the Medicare 
payment amounts for an ADLT during the new ADLT initial period based on 
actual list charge and the weighted median rate exceeds 130 percent, 
CMS will recoup the entire amount of the difference between the 
Medicare payment amounts. We further note that if the 130 percent 
statutory threshold is not exceeded, we are proposing to not recoup at 
all. Thus, for instance, if the weighted median rate is $100 and the 
Medicare payment amount during the initial period is $130 or lower, the 
statutory threshold of 130 percent is not exceeded and we will not 
pursue any recoupment of payment.
    To determine whether the recoupment provision applies, we propose 
to compare the Medicare payment amount based on actual list charge paid 
during the new ADLT initial period and the weighted median rate (as 
calculated from the first time reporting of new ADLT applicable 
information) for each ADLT. If the difference between these two amounts 
exceeds 130 percent, the laboratory will be required to refund the 
difference in total Medicare payments based on actual list charge and 
the weighted median rates. In other words, if the actual list charge 
for a new ADLT is more than 130 percent of the weighted median rate (as 
calculated from applicable information received during the first 
reporting period), claims paid during the new ADLT initial period would 
be re-priced using the weighted median rate. To that end, CMS would 
issue a Technical Direction Letter instructing the MACs to re-price 
claims previously paid during the new ADLT initial period at the 
weighted median rate (instead of the actual list charge for the new 
ADLT). CMS also intends to issue further guidance on the operational 
procedures for recoupment of the new ADLTs that exceed the 130 percent 
threshold.
5. Payment for Existing ADLTs
    Section 1834A(i) of the Act requires the Secretary, for the period 
of April 1, 2014, through December 31, 2016, to use the methodologies 
for pricing, coding, and coverage for ADLTs in effect on the day before 
the enactment of PAMA (April 1, 2014), and provides that those 
methodologies may include crosswalking or gapfilling. Thus, section 
1834A(i) of the Act authorizes us to use crosswalking and gapfilling to 
pay for existing ADLTs, that is, those ADLTs that are paid for under 
the CLFS prior to January 1, 2017. The methodologies in effect on March 
31, 2014 were gapfilling and crosswalking. Therefore, we are proposing 
to use crosswalking and gapfilling to establish the payment amounts for 
existing ADLTs. We would reflect this requirement at Sec.  414.507(h) 
to state that for ADLTs that are furnished between April 1, 2014 and 
December 31, 2016, payment is made based on crosswalking or gapfilling 
methods described in proposed Sec.  414.508(a).
6. Payment for New CDLTs That Are Not ADLTs
    Section 1834A(c) of the Act establishes special provisions for 
determining payment for new CDLTs that are not ADLTs. Section 
1834A(c)(1) of the Act states that payment for a CDLT that is assigned 
a new or substantially revised HCPCS code on or after the April 1, 2014 
enactment date of PAMA, which is not an ADLT, will be determined using 
crosswalking or gapfilling during an initial period until payment rates 
under section 1834A(b) of the Act are established. The test must either 
be crosswalked (as described in Sec.  414.508(a) or any successor 
regulation) to the most appropriate existing test on the CLFS or, if no 
existing test is comparable, paid according to a gapfilling process 
that takes into account specific sources of information, which we 
describe later in this section.
    We developed our current procedures for crosswalking and gapfilling 
new CDLTs pursuant to section 1833(h)(8) of the Act. Section 
1833(h)(8)(A) of the Act requires the Secretary to establish by 
regulation procedures for determining the basis for, and amount of, 
payment for any CDLT for which a new or substantially revised HCPCS 
code is assigned on or after January 1, 2005. Section 1833(h)(8)(B) of 
the Act specifies the annual public consultation process that must take 
place before the Secretary can determine payment amounts for such 
tests, and section 1833(h)(8)(C) of the Act requires the Secretary to 
set forth the criteria for making such determinations and make 
available to the public the data considered in making such 
determinations. We implemented these provisions in the CY 2007 PFS 
final rule (71 FR 69701-69704) published on December 1, 2006.
    We interpret section 1834A(c) of the Act to generally require us to 
use the existing procedures we implemented in 42 CFR part 414, subpart 
G. However, we will need to make some changes to our current 
regulations to reflect

[[Page 59410]]

specific provisions in section 1834A(c) of the Act, as well as other 
aspects of section 1834A of the Act and this proposed rule. In this 
section, we describe those proposed changes and how they would affect 
our current process for setting payment rates for new CDLTs. To 
incorporate section 1834A of the Act within the basis and scope of 
payment for CDLTs, we propose to add a reference to 42 CFR part 414, 
subpart A, entitled ``General Provisions,'' in Sec.  414.1. In 
addition, we propose to change the title of 42 CFR part 414, subpart G, 
to reflect that it applies to payment for all CDLTs, not just new 
CDLTs. We also propose to add a reference to section 1834A of the Act 
in Sec.  414.500. To reflect that Sec.  414.500 would apply to a 
broader scope of laboratory tests than just those covered by section 
1833(h)(8) of the Act, we propose to delete ``new'' and ``with respect 
to which a new or substantially revised Healthcare Common Procedure 
Coding System code is assigned on or after January 1, 2005.''
a. Definitions
    As noted previously, section 1834A(c) of the Act addresses payment 
for a CDLT that is not an ADLT and that is assigned a new or 
substantially revised HCPCS code on or after April 1, 2014, PAMA's 
enactment date. Our current regulations apply throughout to a ``new 
test,'' which we currently define in Sec.  414.502 as any CDLT for 
which a new or substantially revised HCPCS code is assigned on or after 
January 1, 2005. We are proposing to replace ``new test'' with ``new 
CDLT'' in Sec.  414.502 and to make conforming changes throughout the 
regulations to distinguish between the current requirements that apply 
to new tests and the proposed requirements that would apply to new 
CDLTs. Our proposed definition would specify that a new CDLT means a 
CDLT that is assigned a new or substantially revised Healthcare Common 
Procedure Coding System (HCPCS) code, and that does not meet the 
definition of an ADLT. Section 1834A(c)(1) of the Act uses the same 
terminology as section 1833(h)(8)(A) of the Act, ``new or substantially 
revised HCPCS code,'' which we specifically incorporated into the 
definition of new test in Sec.  414.502. We also defined 
``substantially revised HCPCS code'' in Sec.  414.502 based on the 
statutory definition in section 1833(h)(8)(E)(ii) of the Act to mean a 
code for which there has been a substantive change to the definition of 
the test or procedure to which the code applies (such as a new analyte 
or a new methodology for measuring an existing analyte-specific test). 
Because section 1834A(c)(1) of the Act uses terminology that we have 
already defined, and is consistent with our current process, we are not 
proposing any changes to the phrase ``new or substantially revised 
HCPCS code'' in our proposed definition of new CDLT or to the existing 
definition for ``substantially revised HCPCS code.''
b. Crosswalking and Gapfilling
    Background: As we explained in the CY 2008 PFS final rule with 
comment period (71 FR 66275-76), under current Sec.  414.508, we use 
one of two bases for payment to establish a payment amount for a new 
test. Under Sec.  414.508(a), the first basis, called ``crosswalking,'' 
is used if a new test is determined to be comparable to an existing 
test, multiple existing test codes, or a portion of an existing test 
code. If we use crosswalking, we assign to the new test code the local 
fee schedule amount and NLA of the existing test code or codes. If we 
crosswalk to multiple existing test codes, we determine the local fee 
schedule amount and NLA based on a blend of payment amounts for the 
existing test codes. Under Sec.  414.508(a)(2), we pay the lesser of 
the local fee schedule amount or the NLA. The second basis for payment 
is ``gapfilling.'' Under Sec.  414.508(b), we use gapfilling when no 
comparable existing test is available. We instruct each MAC to 
determine a contractor-specific amount for use in the first year the 
new code is effective. (We note that we are proposing to replace 
``carrier'' with contractor to reflect that Medicare has replaced 
fiscal intermediaries and carriers with MACs.) The sources of 
information MACs examine in determining contractor-specific amounts 
include:
     Charges for the test and routine discounts to charges;
     Resources required to perform the test;
     Payment amounts determined by other payers; and
     Charges, payment amounts, and resources required for other 
tests that may be comparable (although not similar enough to justify 
crosswalking) or otherwise relevant.
    During the first year a new test code is paid using the gapfilling 
method, contractors are required to establish contractor-specific 
amounts on or before March 31. Contractors may revise their payment 
amounts, if necessary, on or before September 1, based on additional 
information. After the first year, the contractor-specific amounts are 
used to calculate the NLA, which is the median of the contractor-
specific amounts, and under Sec.  414.508(b)(2), the test code is paid 
at the NLA in the second year. We instruct MACs to use the gapfilling 
method through program instruction, which lists the specific new test 
code and the timeframes to establish contractor-specific amounts.
    In the CY 2007 PFS final rule with comment period (71 FR 69702), we 
also described the timeframes for determining the amount of and basis 
for payment for new tests. The codes to be included in the upcoming 
year's fee schedule (effective January 1) are available as early as 
May. We list the new clinical laboratory test codes on our Web site, 
usually in June, along with registration information for the public 
meeting, which is held no sooner than 30 days after we announce the 
meeting in the Federal Register. The public meeting is typically held 
in July. In September, we post our proposed determination of the basis 
for payment for each new code and seek public comment on these proposed 
determinations. The updated CLFS is prepared in October for release to 
our contractors during the first week in November so that the updated 
CLFS is ready to pay claims effective January 1 of the following 
calendar year. Under Sec.  414.509, for a new test for which a new or 
substantially revised HCPCS code was assigned on or after January 1, 
2008, CMS accepts reconsideration requests in written format for 60 
days after making a determination of the basis for payment (either 
crosswalking or gapfilling) regarding whether CMS should reconsider the 
basis for payment and/or amount of payment assigned to the new test. If 
a requestor recommends that the basis for payment should be changed 
from gapfilling to crosswalking, the requestor may also recommend the 
code or codes to which to crosswalk the new test. The reconsideration 
request would be presented for public comment at the next public 
meeting, the following year. After considering the public comments, if 
CMS decides to change the amount of payment for the code, the new 
payment amount would be effective January 1 of the year following the 
reconsideration.
    Section 1834A(c)(1) of the Act refers to payment for CDLTs for 
which a new or substantially revised HCPCS code is assigned on or after 
the April 1, 2014 enactment date of PAMA. We note that the annual 
crosswalking and gapfilling process has already occurred for codes on 
the 2015 CLFS, and is currently underway for codes on the 2016 CLFS. We 
are proposing to continue using the current crosswalking and gapfilling 
processes for CDLTs assigned new or substantially revised HCPCS codes 
prior to January 1, 2017 because: section 1834A(c)(1)(A) of the Act 
refers to our

[[Page 59411]]

existing crosswalking process under Sec.  414.508(a); we would not have 
been able to finalize new crosswalking requirements as of PAMA's April 
1, 2014 enactment date; and the current payment methodology involving 
NLAs and local fee schedule amounts will remain in effect until January 
1, 2017. We would update Sec.  414.508 by changing the introductory 
language to limit paragraphs (a) and (b) (which would be redesignated 
as paragraphs (a)(1) and (a)(2)) to tests assigned new or substantially 
revised HCPCS codes ``between January 1, 2005 and December 31, 2016,'' 
and adding introductory language preceding new proposed paragraphs 
(b)(1) and (b)(2) to reflect our proposal to pay for a CDLT that is 
assigned a new or substantially revised HCPCS code on or after January 
1, 2017 based on either crosswalking or gapfilling.
    For CDLTs that are assigned a new or substantially revised HCPCS 
codes on or after January 1, 2017, we are proposing to use comparable 
crosswalking and gapfilling processes that are modified to reflect the 
new market-based payment system under section 1834A of the Act. As 
discussed previously, beginning January 1, 2017, the payment 
methodology established under section 1834A(b) of the Act will replace 
the current payment methodology under sections 1833(a), (b), and (h) of 
the Act, including NLAs and local fee schedule amounts. Thus, we are 
proposing to establish Sec.  414.508(b)(1) and (2) to describe 
crosswalking and gapfilling processes that do not involve NLAs or local 
fee schedule amounts.
    Regarding the crosswalking process, because section 1834A(c)(1)(A) 
of the Act specifically references our existing process under Sec.  
414.508(a), we are not proposing to change the circumstances when we 
use crosswalking, that is, when we determine the new CDLT is comparable 
to an existing test, multiple existing test codes, or a portion of an 
existing test code. For a CDLT assigned a new or substantially revised 
HCPCS code on or after January 1, 2017, we are proposing to establish 
the following crosswalking process in Sec.  414.508(b)(1), which does 
not rely on NLAs or local fee schedule amounts:
    Crosswalking: Crosswalking is used if it is determined that a new 
CDLT is comparable to an existing test, multiple existing test codes, 
or a portion of an existing test code.
     CMS assigns to the new CDLT code, the payment amount 
established under Sec.  414.507 for the existing test.
     Payment for the new CDLT code is made at the payment 
amount established under Sec.  414.507 for the existing test.
    Regarding the gapfilling process, section 1834A(c)(2) of the Act 
requires the use of gapfilling if no existing test is comparable to the 
new test. Section 1834A(c)(2) of the Act specifies that this gapfilling 
process must take into account the following sources of information to 
determine gapfill amounts, if available:
     Charges for the test and routine discounts to charges.
     Resources required to perform the test.
     Payment amounts determined by other payors.
     Charges, payment amounts, and resources required for other 
tests that may be comparable or otherwise relevant.
     Other criteria the Secretary determines appropriate.
    The first four criteria are identical to the criteria currently 
specified in Sec.  414.508(b)(1). For this reason, we are not proposing 
any substantive changes to the factors that must be considered in the 
gapfilling process. The fifth criterion authorizes the Secretary to 
establish other criteria for gapfilling as the Secretary determines 
appropriate. At this time, we are not proposing any additional factors 
to determine gapfill amounts. If we decide to establish additional 
gapfilling criteria, we will do so through notice and comment 
rulemaking.
    We are proposing to establish a gapfilling process for CDLTs 
assigned a new or substantially revised HCPCS code on or after January 
1, 2017, that would be similar to the gapfilling process currently 
included in Sec.  414.508(b), but would eliminate the reference to the 
NLA in Sec.  414.508(b)(2), as that term would no longer be applicable, 
and would substitute ``Medicare Administrative Contractor'' (MAC) for 
``carrier,'' as MACs are now Medicare's claims processing contractors. 
To determine a payment amount under this gapfilling process, we are 
proposing to pay the test code at an amount equal to the median of the 
contractor-specific payment amounts, consistent with the current 
gapfilling methodology at Sec.  414.508(b). Section Sec.  414.508(b)(2) 
would state that gapfilling is used when no comparable existing CDLT is 
available. We would state in Sec.  414.508(b)(2)(i) that, in the first 
year, Medicare Administrative Contractor-specific amounts are 
established for the new CDLT code using the following sources of 
information to determine gapfill amounts, if available:
     Charges for the test and routine discounts to charges;
     Resources required to perform the test;
     Payment amounts determined by other payers; and
     Charges, payment amounts, and resources required for other 
tests that may be comparable or otherwise relevant.
     Other criteria CMS determines appropriate.
    We would state in Sec.  414.508(b)(2)(ii) that, in the second year, 
the CDLT code is paid at the median of the MAC-specific amounts.
    We note that section 1834A(c)(1) of the Act requires the 
crosswalked and gapfilled payment amounts for new CDLTs to be in effect 
``during an initial period'' until payment rates under section 1834A(b) 
of the Act are established. As discussed previously, we typically list 
new CDLT codes on our Web site by June, and by January 1 of the 
following calendar year, we have either established payment amounts 
using crosswalking or indicated that a test is in its first year of the 
gapfilling process. Because we are proposing to largely continue our 
existing gapfilling and crosswalking processes, for CDLTs assigned new 
or substantially revised HCPCS codes on or after January 1, 2017, we 
believe the initial period is the period of time until applicable 
information is reported for a CDLT and can be used to establish a 
payment amount using the weighted median methodology in Sec.  
414.507(b).
    We would continue to permit reconsideration of the basis and amount 
of payment for CDLTs as we currently do under Sec.  414.509. For a new 
CDLT for which a new or substantially revised HCPCS code was assigned 
on or after January 1, 2008, CMS accepts reconsideration requests in 
written format for 60 days after making a determination of the basis 
for payment (either crosswalking or gapfilling) or the payment amount 
assigned to the new test code, per Sec.  414.509(a)(1), (b)(1)(i) and 
(b)(2)(ii). The requestor may also request to present its 
reconsideration request at the next annual public meeting, typically 
convened in July of each year under Sec.  414.509(a)(2)(i) and 
(b)(1)(ii)(A). Under Sec.  414.509(a)(1), if a requestor recommends 
that the basis for payment should be changed from gapfilling to 
crosswalking, the requestor may also recommend the code or codes to 
which to crosswalk the new test. After considering the comments 
received, CMS may reconsider the basis for payment under Sec.  
414.509(a)(3) and (b)(1)(iii) or its determination of the amount of 
payment, which could

[[Page 59412]]

include a revised NLA for the new code under Sec.  414.509(b)(2)(v). 
However, as previously noted in this section, the NLA will no longer be 
applicable on and after January 1, 2017, and we would instead refer to 
the national payment amount under crosswalking or gapfilling as the 
median of the contractor-specific payment amounts. Therefore, we 
propose to revise Sec.  414.509 to replace references to the ``national 
limitation amount'' with ``median of the Medicare Administrative 
Contractor-specific payment amount'' in Sec.  414.509(b)(2)(iv) and 
(b)(2)(v). We would also replace ``carrier-specific amount'' where it 
appears in Sec.  414.509 with ``Medicare Administrative Contractor-
specific payment amount'' because we now refer to our Medicare Part B 
claims processing contractors as Medicare Administrative Contractors.
c. Public Consultation Procedures
    Advisory Panel Recommendations: Our current procedures for public 
consultation for payment for a new test are addressed in Sec.  414.506. 
Section 1834A(c)(3) of the Act requires the Secretary to consider 
recommendations from the expert outside advisory panel established 
under section 1834A(f)(1) of the Act when determining payment using 
crosswalking or gapfilling processes. In section II.J.1, we describe 
the Advisory Panel on CDLTs (the Panel). We are proposing to specify 
that the public consultation process regarding payment for new CDLTs on 
or after January 1, 2017, must include the Panel's recommendations by 
adding Sec.  414.506(e) to specify that CMS will consult with an expert 
outside advisory panel, called the Advisory Panel on CDLTs, composed of 
an appropriate selection of individuals with expertise, which may 
include molecular pathologists, researchers, and individuals with 
expertise in laboratory science or health economics in issues related 
to CDLTs . This advisory panel will provide input on the establishment 
of payment rates under Sec.  414.508 and provide recommendations to CMS 
under this subpart.
    Explanation of Payment Rates: Section 1834A(c)(4) of the Act 
requires the Secretary to make available to the public an explanation 
of the payment rate for a new CDLT, including an explanation of how the 
gapfilling criteria are applied and how the recommendations of the 
Advisory Panel on CDLTs are applied. Currently, Sec.  414.506(d) 
provides that, considering the comments and recommendations (and 
accompanying data) received at the public meeting, CMS develops and 
makes available to the public (through an Internet Web site and other 
appropriate mechanisms) a list of:
     Proposed determinations with respect to the appropriate 
basis for establishing a payment amount for each code, with an 
explanation of the reasons for each determination, the data on which 
the determinations are based, and a request for public written comments 
within a specified time period on the proposed determination; and
     Final determinations of the payment amounts for tests, 
with the rationale for each determination, the data on which the 
determinations are based, and responses to comments and suggestions 
from the public.
    Section 414.506(d) already indicates that CMS will provide an 
explanation of the payment rate determined for each new CDLT and the 
rationale for each determination. As described above, under our current 
process, we make available to the public proposed payment rates with 
accompanying rationales and supporting data, as well as final payment 
rates with accompanying rationales and supporting data. However, this 
process has been used almost exclusively for new tests that are 
crosswalked. For tests that are gapfilled, we generally post the 
contractor-specific amounts in the first year of gapfilling on the CMS 
Web site and provide for a public comment period, but do not typically 
provide explanations of final payment amounts. Based on section 
1834A(c)(4) of the Act, we are proposing to amend Sec.  414.506 to 
explicitly indicate that, for a new CDLT on or after January 1, 2017, 
we will provide an explanation of gapfilled payment amounts and how we 
took into account the Panel's recommendations. Specifically, we are 
proposing to add paragraphs (3) and (4) to Sec.  414.506(d). In Sec.  
414.506(d)(3), we would specify that, for a new CDLT, in applying 
paragraphs (1) and (2), CMS will provide an explanation of how it took 
into account the recommendations of the Advisory Panel on CDLTs. In 
Sec.  414.506(d)(4), we would specify that, for a new CDLT, in applying 
paragraphs (1) and (2) and Sec.  414.509(b)(2)(i) and (iii) when CMS 
uses the gapfilling method described in Sec.  414.508(b)(2), CMS will 
make available to the public an explanation of the payment rate for the 
test.
    Under these provisions, we would publish the Medicare payment 
amounts for new CDLTs along with an explanation of the payment rate and 
how the gapfilling criteria and recommendations by the Advisory Panel 
on CDLTs were applied via the CMS CLFS Web site as we currently do for 
new tests. The CMS CLFS Web site may be accessed at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/ClinicalLabFeeSched/.
7. Medicare Payment for Tests Where No Applicable Information Is 
Reported
    While sections 1834A(b), (c), and (d), of the Act, respectively, 
address payment for CDLTs and ADLTs as of January 1, 2017, the statute 
does not address how we must pay for a laboratory test when no 
applicable information is reported by applicable laboratories.
    There are several possible reasons why no applicable information 
would be reported for a laboratory test. For example:
     Test is Not Performed for Any Privately Insured Patients 
During the Data Collection Period. One reason CMS may not receive any 
applicable information is that the test is not performed for a 
privately insured patient by an applicable laboratory during the data 
collection period.
     Test is Not Performed by Any Applicable 
Laboratories. Another reason why CMS may not receive applicable 
information is that none of the laboratories performing the test during 
a data collection period are applicable laboratories as defined in 
proposed Sec.  414.502. For example, the laboratories could be hospital 
laboratories that, in a data collection period, did not receive more 
than 50 percent of their Medicare revenues from the CLFS and the PFS. 
Or, they may be laboratories that received less than $50,000 a year in 
Medicare revenues under the CLFS (or less than $25,000 in Medicare 
revenues under the CLFS for the proposed 6-month data collection period 
for CY 2015). As we stated in section II.A. of this proposed rule, we 
estimate that in 2013 there were 17 laboratory tests with utilization 
completely attributed to entities that would not have been applicable 
laboratories because they did not meet the $50,000 threshold.
     Special Situations Involving ADLTs. It is also 
possible that a laboratory that performs a test that would qualify to 
be an ADLT, does not meet the definition of an applicable laboratory 
and, therefore, cannot report applicable information. As discussed in 
section II.C. of this proposed rule, an ADLT is a test that is 
performed by only a single laboratory. If that laboratory is not an 
applicable laboratory, we would not receive applicable information for 
the test. As discussed above, this situation could occur if the only 
laboratory performing the test did not receive more than 50 percent of 
its Medicare revenues from the CLFS and the PFS, or received less than 
$50,000 a year in Medicare revenues under the CLFS (or less than

[[Page 59413]]

$25,000 in Medicare revenues under the CLFS for the proposed 6-month 
data collection period for CY 2015).
     Other Reasons Not Specified. It is possible we 
may not receive applicable information for a laboratory test if an 
applicable laboratory fails to comply with the reporting requirements 
under section 1834A of the Act for which the laboratory may be 
penalized under section 1834A(a)(9) of the Act (we address CMPs for 
non-reporting in section II.E.1. of this proposed rule). There may also 
be other reasons we cannot anticipate where we might not receive 
applicable information for a laboratory test in a data collection 
period.
    In the event we do not receive applicable information for a 
laboratory test that is provided to a Medicare beneficiary, we would 
need to determine a payment amount for the test in the year following 
the data collection period. The statute does not specify the 
methodology we must use to establish the payment rate for an ADLT or 
CDLT for which we receive no applicable information in a data reporting 
period but for which we need to establish a payment amount. In such 
circumstances, we propose to use crosswalking and gapfilling using the 
proposed definitions in Sec.  414.508(b)(1) and (2) to establish a 
payment rate on or after January 1, 2017, which would remain in effect 
until the year following the next data reporting period. This policy 
would include the situation where we receive no applicable information 
for tests that were previously priced using gapfilling or crosswalking 
or where we had previously priced a test using the weighted median 
methodology. If CMS receives no applicable information in a subsequent 
data reporting period, we would use crosswalking or gapfilling 
methodologies to establish the payment amount for the test. In other 
words, if in a subsequent data reporting period, no applicable 
information is reported, CMS would reevaluate the basis for payment, of 
crosswalking or gapfilling, and the payment amount for the test.
    In exploring what we would do if we receive no applicable 
information for a CDLT, we alternatively considered carrying over the 
current payment amount for a test under the current CLFS, the payment 
amount for a test (if one was available) using the weighted median 
methodology based on applicable information from the previous data 
reporting period, or the gapfilled or crosswalked payment amount. 
However, we are not proposing this approach because we believe carrying 
over previous payment rates would not reflect changes in costs or 
pricing for the test over time. We understand the purpose of section 
1834A of the Act is to update the CLFS rates to reflect changes in 
market prices over time.
    As noted above, the statute does not address situations where we 
price a test using crosswalking or gapfilling because we received no 
applicable information with which to determine a CLFS rate. We believe 
reconsidering rates for tests in these situations would be consistent 
with the purpose of section 1834A of the Act, which requires us to 
periodically reconsider CLFS payment rates. In the case of tests for 
which we previously received applicable information to determine 
payment rates, section 1834A of the Act requires Medicare to follow 
changes in the market rates for private payors. Our proposal serves an 
analogous purpose by periodically reconsidering the payment rate of a 
test using gapfilling or crosswalking. We expect to continue to 
evaluate our proposed approach to setting rates for laboratory tests 
paid on the CLFS with no reported applicable information as we gain 
more programmatic experience under the new CLFS. Any revisions to how 
we determine a rate for laboratory tests without reported applicable 
information would be addressed in the future through notice and comment 
rulemaking.
    In summary, we propose that for a CDLT, including ADLTs, for which 
we receive no applicable information in a data reporting period, CMS 
will determine the payment amount based on either crosswalking or 
gapfilling. We propose to add paragraph (g) to Sec.  414.507 to specify 
that for CDLTs for which CMS receive no applicable information, payment 
is made based on the crosswalking or gapfilling methods described in 
Sec.  414.508(b)(1) and (2).

I. Local Coverage Determination Process and Designation of Medicare 
Administrative Contractors for Clinical Diagnostic Laboratory Tests

    Section 1834A(g) of the Act addresses issues related to coverage of 
CDLTs. Section 1834A(g)(1)(A) of the Act requires that coverage 
policies for CDLTs, when issued by a MAC, be issued in accordance with 
the LCD process. The current LCD development and implementation process 
is set forth in agency guidance. Section 1869(f)(2)(B) of the Act, 
however, defines an LCD as a determination by a MAC under part A or 
part B, as applicable, respecting whether or not a particular item or 
service is covered on a MAC jurisdiction-wide basis under such parts, 
in accordance with section 1862(a)(1)(A) of the Act.
    While the LCD development process is not enumerated in statute, 
CMS' Internet-Only Manual 100-08, Medicare Program Integrity Manual, 
Chapter 13, lays out the process for establishing LCDs. The manual 
outlines the steps in LCD development including: The posting of a draft 
LCD, a public comment period, and issuance of a final LCD followed by 
at least a 45-day notice period prior to the policy becoming effective. 
In addition, there are opportunities for public meetings. This LCD 
development process has been used by the MACs since 2003.
    In addition to addressing LCD development and implementation, 
section 1834A(g)(1)(A) of the Act states that the processes governing 
the appeal and review of LCDs for CDLTs must be consistent with the 
general LCD appeal and review rules that CMS has issued at 42 CFR part 
426. The LCD appeals process establishes a process for an ``aggrieved 
party'' to challenge an LCD or LCD provisions in effect at the time of 
the challenge. An aggrieved party is defined as a Medicare beneficiary, 
or the estate of a Medicare beneficiary, who is entitled to benefits 
under Part A, enrolled under Part B, or both (including an individual 
enrolled in fee-for-service Medicare, in a Medicare+Choice plan, or in 
another Medicare managed care plan), and is in need of coverage for an 
item or service that would be denied by an LCD, as documented by the 
beneficiary's treating physician, regardless of whether the service has 
been received.
    Section 1834A(g)(1)(B) of the Act provides that the CDLT-related 
LCD provisions referenced in section 1834A(g) do not apply to the NCD 
process (as defined in section 1869(f)(1)(B) of the Act). The NCD 
process is outlined in section 1862(l) and further articulated in the 
August 7, 2013 Federal Register (78 FR 48164).
    Section 1834A(g)(1)(C) of the Act specifies that the provisions 
pertaining to the LCD process for CDLTs, including appeals, shall apply 
to coverage policies issued on or after January 1, 2015.
    Beyond specifying how the Medicare LCD process will relate to 
CDLTs, section 1834A(g)(2) of the Act provides the Secretary the 
discretion to designate one or more (not to exceed four) MACs to either 
establish LCDs for CDLTs or to both establish LCDs and process Medicare 
claims for payment for CDLTs. Currently, there are 12 MACs that have 
authority to establish LCDs and process claims for CDLTs. We believe 
the statute authorizes CMS to reduce the number of MACs issuing LCDs 
for CDLTs, which

[[Page 59414]]

would result in fewer contractors issuing policies for larger 
geographic areas. If we were to exercise only the authority to reduce 
the number of MACs issuing LCDs for CDLTs, such a change could likely 
be finalized within the next 2 to 4 years. However, reducing the number 
of MACs processing claims for CDLTs would involve significantly more 
complex programmatic and operational issues. For instance, the 
consolidation of Medicare claims processing for CDLTs would require 
complex changes to Medicare's computer systems. Thus, such a transition 
could take several years to implement. To be consistent with the 
statute, we believe the agency needs to conduct the necessary analyses 
to determine the feasibility and program desirability of moving forward 
with consolidating the number of MACs making coverage policies and 
processing claims for CDLTs. We believe that the medical complexity and 
the volume of these test requires the agency to seriously consider 
consolidating all MAC CDLT processes into 1-4 MACs. Therefore, we are 
seeking input from stakeholders on the components and feasibility of 
moving forward with consolidation all MAC CDLT process into 1-4 MACs.
    For instance, should only coverage policies be developed by a 
smaller number of MACs, issues could arise for the other A/B MACs that 
would need to implement policies, edit claims and defend LCD policies 
that they did not author. Moreover, the same policy may be implemented 
differently among MACs based on the ability of their individual claims 
processing systems to support certain types of editing and/or their 
differing assessment of risk and technical solutions. Finally, if both 
LCD development and claims processing were combined and consolidated, 
CMS would need to consider that the MAC processing the laboratory claim 
will (in most cases) not be the same MAC that processes the claim of 
the ordering physician. This may complicate the development of a full 
profile of the ordering physicians' practice patterns for quality and 
medical necessity assessment purposes. Accordingly, at this time, we 
are requesting public comment on the benefits and disadvantages of 
implementing the new discretionary authority to consolidate the number 
of MACs developing LCDs for CDLTs. We are also soliciting comments on 
whether CMS should utilize the broadest discretion provided by the 
statute to task four or fewer MACs with the responsibility of both 
writing CDLT-related LCDs and processing all CDLT claims. We also 
invite comments on other alternatives permissible within the scope of 
the new legislative authority that CMS should consider which are not 
outlined here.
    The timing for implementation of section 1834A(g)(2) of the Act (if 
we chose to exercise this authority) would be largely dependent on the 
ability of the agency to develop statements of work, modify existing or 
develop new MAC contracts, and address the policy, information 
technology and technical aspects of the claims processing environment 
including the potential development of a new system. Implementing the 
fullest scope of the authority granted by this section, by which CMS 
would reduce both the number of MACs writing coverage policies for CDLT 
services and the number of MACs processing CDLT claims, could take 
upwards of 5 to 6 years. To establish centralized LCDs for all CDLTs 
would probably involve an initial build-up and then a steady-state 
investment of between $10 and $15M per year. To create regional lab 
claims processors (in addition to development of LCDs) would involve 
higher set-up costs, and some steady-state costs. The reduction in A/B 
MACs operating costs would likely not fully offset the cost of the 
specialty lab MACs since the A/B MACs would continue to develop LCDs 
for other Medicare benefits. CMS is not aware of PAMA funds for this 
activity, and so CMS would need to obtain any needed incremental 
implementation and operational funding through the regular Program 
Management appropriation process. However, prior to the agency 
committing to any direction regarding the number of MACs involved and 
the purview of their responsibilities, we are seeking public comment on 
the benefits and risks of implementing the various scenarios authorized 
by this section of the statute.

J. Other Provisions

1. Advisory Panel on Clinical Diagnostic Laboratory Tests
    Section 1834A(f) of the Act sets out several requirements for input 
from clinicians and technical experts on issues related to CDLTs. 
Section 1834A(f)(1) of the Act requires the Secretary to consult with 
an expert outside advisory panel that is to be established by the 
Secretary no later than July 1, 2015. This advisory panel must be 
composed of an appropriate selection of individuals with expertise, 
which may include molecular pathologists, researchers, and individuals 
with expertise in laboratory science or health economics, in issues 
related to CDLTs, which may include the development, validation, 
performance, and application of such tests.
    Section 1834A(f)(1)(A) of the Act provides that the advisory panel 
will generally provide input on the establishment of payment rates for 
new CDLTs, including whether to use crosswalking or gapfilling 
processes to determine payment for a specific new test and the factors 
used in determining coverage and payment processes for new CDLTs. 
Section 1834A(f)(1)(B) of the Act provides that the panel will provide 
recommendations to the Secretary under section 1834A of the Act. 
Section 1834A(f)(2) of the Act mandates that the panel comply with the 
requirements of the Federal Advisory Committee Act (5 U.S.C. App.) 
(FACA). As discussed in section II.H.6. of this proposed rule, we are 
proposing to add Sec.  414.506(e) to codify the establishment of the 
Advisory Panel on CDLTs.
    In the October 27, 2014 Federal Register (79 FR 63919), CMS 
announced the Advisory Panel on CDLTs. On April 16, 2015, CMS 
established the charter for the Panel. (See https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/ClinicalLabFeeSched/Downloads/PAMA-Tab-F-1635-N.pdf). As indicated in the charter, meetings 
will be held up to 4 times a year. Meetings will be open to the public 
except as determined otherwise by the Secretary or other official to 
whom the authority has been delegated in accordance with the Government 
in the Sunshine Act of 1976 (5 U.S.C. 552b(c)) and FACA. Notice of all 
meetings will be published in the Federal Register as required by 
applicable laws and Departmental regulations. Meetings will be 
conducted, and records of the proceedings kept, as required by 
applicable laws and departmental regulations. Additionally, in the 
August 7, 2015 Federal Register (80 FR 47491), CMS announced membership 
appointments to the Panel along with the first meeting date for the 
Panel. As we do with the Advisory Panel on Hospital Outpatient Payment 
(see https://www.cms.gov/Regulations-and-Guidance/Guidance/FACA/AdvisoryPanelonAmbulatoryPaymentClassificationGroups.html), we will 
make the Advisory Panel on CDLT's recommendations publicly available on 
the CMS Web site shortly after the panel's meeting. The first meeting 
of the panel was held at CMS on August 26, 2015. Information regarding 
the Panel is available at https://www.cms.gov/Regulations-and-Guidance/Guidance/FACA/AdvisoryPanelonClinicalDiagnosticLaboratoryTests.html.

[[Page 59415]]

2. Exemption From Administrative and Judicial Review
    Section 1834A(h)(1) of the Act states that there shall be no 
administrative or judicial review under section 1869 of the Act, 
section 1878 of the Act, or otherwise, of the establishment of payment 
amounts under section 1834A of the Act. We are proposing to codify this 
provision in Sec.  414.507(e).
3. Sample Collection Fee
    Section 1834A(b)(5) of the Act increases by $2 the nominal fee that 
would otherwise apply under section 1833(h)(3)(A) of the Act for a 
sample collected from an individual in a SNF or by a laboratory on 
behalf of a HHA. This provision was implemented via Medicare Change 
Request (CR) transmittal effective December 1, 2014 (Transmittal 
#R3056CP; CR #8837). We propose to reflect this policy in Sec.  
414.507(f).

III. Collection of Information Requirements

    As stated in section 1834A(h)(2) of the Act, Chapter 35 of title 
44, United States Code, shall not apply to the information collection 
requirements contained in section 1834A of the Act. Consequently, the 
information collection requirements contained in this notice of 
proposed rulemaking need not be reviewed by the Office of Management 
and Budget.

IV. Response to Comments

    Because of the large number of public comments we normally receive 
on Federal Register documents, we are not able to acknowledge or 
respond to them individually. We will consider all comments we receive 
by the date and time specified in the DATES section of this preamble, 
and, when we proceed with a subsequent document, we will respond to the 
comments in the preamble to that document.

V. Regulatory Impact Analysis

A. Statement of Need

    This proposed rule is necessary to establish a methodology for 
implementing the requirements in section 1834A of the Act, including a 
proposed process for data collection and reporting, a proposed weighted 
median calculation methodology, and proposed requirements for how and 
to whom these policies would apply.

B. Overall Impact

    We have examined the impacts of this rule as required by Executive 
Order 12866 on Regulatory Planning and Review (September 30, 1993), 
Executive Order 13563 on Improving Regulation and Regulatory Review 
(January 18, 2011), the Regulatory Flexibility Act (RFA) (September 19, 
1980, Pub. L. 96-354), section 1102(b) of the Act, section 202 of the 
Unfunded Mandates Reform Act of 1995 (March 22, 1995; Pub. L. 104-4), 
Executive Order 13132 on Federalism (August 4, 1999) and the 
Congressional Review Act (5 U.S.C. 804(2).
    Executive Orders 12866 and 13563 direct agencies to assess all 
costs and benefits of available regulatory alternatives and, if 
regulation is necessary, to select regulatory approaches that maximize 
net benefits (including potential economic, environmental, public 
health and safety effects, distributive impacts, and equity). Section 
3(f) of Executive Order 12866 defines a ``significant regulatory 
action'' as an action that is likely to result in a rule: (1) Having an 
annual effect on the economy of $100 million or more in any 1 year, or 
adversely and materially affecting a sector of the economy, 
productivity, competition, jobs, the environment, public health or 
safety, or state, local or tribal governments or communities (also 
referred to as ``economically significant''); (2) creating a serious 
inconsistency or otherwise interfering with an action taken or planned 
by another agency; (3) materially altering the budgetary impacts of 
entitlement grants, user fees, or loan programs or the rights and 
obligations of recipients thereof; or (4) raising novel legal or policy 
issues arising out of legal mandates, the President's priorities, or 
the principles set forth in the Executive Order.
    A regulatory impact analysis (RIA) must be prepared for major rules 
with economically significant effects ($100 million or more in any 1 
year). This proposed rule is an economically significant rule because 
we believe that the changes to how CLFS payment rates will be developed 
will overall decrease payments to entities paid under the CLFS. We 
estimate that this rulemaking is ``economically significant'' as 
measured by the $100 million threshold, and hence also a major rule 
under the Congressional Review Act. Accordingly, we have prepared a 
Regulatory Impact Analysis that, to the best of our ability, presents 
the costs and benefits of the rulemaking.

C. Limitations of Our Analysis

    Our analysis presents the projected effects of our proposed 
implementation of new section 1834A of the Act. As described earlier in 
this proposed rule, a part of this proposed rule describes a schedule 
and process for collecting private payor rate information from certain 
laboratories. Until such time that these data are available, we are 
limited in our ability to estimate effects of our proposed CLFS payment 
policies under different scenarios.

D. Anticipated Effects

1. Effects on Entities Paid Under the CLFS
    The RFA requires agencies to analyze options for regulatory relief 
of small entities if a rule has a significant impact on a substantial 
number of small entities. For purposes of the RFA, we estimate that 
most of the entities paid under the CLFS are small entities as that 
term is used in the RFA (including small businesses, nonprofit 
organizations, and small governmental jurisdictions). The great 
majority of hospitals and most other health care providers and 
suppliers are small entities, either by being nonprofit organizations 
or by meeting the SBA definition of a small business (having revenues 
of less than $7.5 million to $38.5 million in any 1 year).
    For purposes of the RFA, we estimate that most entities furnishing 
laboratory tests paid under the CLFS are considered small businesses 
according to the Small Business Administration's size standards with 
total revenues of $15 million or less in any 1 year: $15 million for 
testing laboratories and $11 million for doctors. Individuals and 
states are not included in the definition of a small entity. Using the 
codes for laboratories in the North American Industry Classification 
System (NAICS), 93 percent of medical laboratories would be considered 
small businesses. This rule will have a significant impact on a 
substantial number of small businesses or other small entities even 
with an exception for low expenditure laboratories.
    As discussed previously in this proposed rule, we are proposing to 
define applicable laboratory at the TIN level. Approximately 68,000 
unique TIN entities are enrolled in the Medicare program as a 
laboratory and paid under the CLFS. Of these unique TIN entities, 94 
percent are enrolled as a physician office laboratory, 3 percent are 
enrolled as independent laboratories while the remaining 3 percent are 
attributed to other types of laboratories such as those operating 
within a rural health clinic or a skilled nursing facility. Given that 
well over 90 percent of the Medicare enrolled laboratories paid under 
the CLFS are physician office laboratories, we estimate the majority of 
Medicare enrolled laboratories would meet the SBA definition of a small 
business.

[[Page 59416]]

    As discussed in section II.D. of this proposed rule, applicable 
laboratories will be required to report applicable information to CMS, 
which includes each private payor rate, the associated volume of tests 
performed corresponding to each private payor rate, and the specific 
HCPCS code associated with the test. We are specifically proposing to 
minimize the reporting burden by only requiring the minimum information 
necessary to enable us to set CLFS payment rates. We are not requiring 
(or permitting) applicable laboratories to report individual claims 
because claims include more information than we need to set payment 
rates (and also raises concerns about reporting personally identifiable 
information). We believe that each of these proposals will 
substantially reduce the reporting burden for applicable laboratories 
in general and small businesses in particular. We discuss reporting 
requirements further in section V.E. of this proposed rule.
    Given that we have never collected information about private payor 
rates for tests from laboratories, we do not have the specific payment 
amounts from the weighted median of private payor rates that will 
result from implementation of section 1834A of the Act. For this 
reason, it is not possible to determine an impact at the level of the 
individual laboratory or physician office laboratory much less 
distinctly for small and other businesses. While the information 
provided elsewhere in this impact statement provide the aggregate level 
of changes in payments, these estimates were done by comparing the 
differences in payment amounts for laboratory tests from private payers 
with the Medicare CLFS payment adjusted for changes expected to occur 
by CY 2017. While this methodology can be used to estimate an overall 
aggregate change in payment for services paid using the CLFS, the 
impact on any individual laboratory will depend on the mix of 
laboratory services provided by the individual laboratory or physician 
office. A proposed regulation is generally deemed to have a significant 
impact on small businesses if the rule is estimated to have an impact 
greater than a 3 to 4 percentage change to their revenue. As discussed 
previously in this section, we estimate that most entities furnishing 
laboratory tests paid under the CLFS would be considered a small 
business. Therefore, we believe our accounting statement would provide 
a reasonable representation of the impact of the proposed changes to 
the CLFS on small businesses (see Table 11). As illustrated in Table 
11, the effect on the Medicare program is expected to be $360 million 
less in Part B program payments for CLFS tests furnished in FY 2017. 
The 5-year impact is estimated to be $2.94 billion less and the 10-year 
impact is expected to result in $5.14 billion less in program payments. 
As discussed in section I.B., overall, Medicare pays approximately $8 
billion a year under the current CLFS for CDLTs. Using our estimated 
amount of proposed changes in CLFS spending, we estimate an overall 
percentage reduction in revenue of approximately -4.5 percent for FY 
2017 (-$360 million/$8 billion = -4.5 percent); a 5-year percentage 
reduction of about 7.4 percent (-$2.94 billion/$40 billion = -7.35 
percent) and a 10-year percentage reduction of approximately 6.4 
percent (-$5.14 billion/$80 billion = -6.43 percent). As such, we 
estimate that the proposed revisions to the CLFS as authorized by PAMA 
would have a significant impact on small businesses.
    In addition, section 1102(b) of the Act requires us to prepare a 
regulatory impact analysis if a rule may have a significant impact on 
the operations of a substantial number of small rural hospitals. This 
analysis must conform to the provisions of section 603 of the RFA. For 
purposes of section 1102(b) of the Act, we define a small rural 
hospital as a hospital that is located outside of a metropolitan 
statistical area and has fewer than 100 beds. This proposed rule will 
not have a significant impact on small rural hospitals because the 
majority of entities paid under the CLFS and affected by this proposal 
are independent laboratories and physician offices. To the extent that 
rural hospitals own independent laboratories and to the extent that 
rural hospitals are paid under the CLFS, there could be a significant 
impact on those facilities. Since most payments for laboratory tests to 
hospitals are bundled in Medicare severity Diagnosis Related Group 
payments under Part A, the Secretary has determined that this proposed 
rule will not have a significant impact on the operations of a 
substantial number of small rural hospitals. We request comment from 
small rural hospitals on (1) their relationships with independent 
clinical laboratories and (2) the potential impact of a reduction in 
CLFS payments on their revenues and profits.
    Section 202 of the Unfunded Mandates Reform Act of 1995 (UMRA) also 
requires that agencies assess anticipated costs and benefits before 
issuing any rule whose mandates require spending in any 1 year of $100 
million in 1995 dollars, updated annually for inflation. In 2015, that 
is approximately $144 million. This proposed rule does not contain 
mandates that will impose spending costs on State, local, or tribal 
governments in the aggregate, or by the private sector.
    Executive Order 13132 establishes certain requirements that an 
agency must meet when it promulgates a proposed rule (and subsequent 
final rule) that imposes substantial direct costs on State and local 
governments, preempts State law, or otherwise has Federalism 
implications. We have examined the CLFS provisions included in this 
proposed rule in accordance with Executive Order 13132, Federalism, and 
have determined that they will not have a substantial direct effect on 
State, local or tribal governments, preempt State law, or otherwise 
have a Federalism implication. While we have limited information about 
entities billing the CLFS with government ownership, the limited amount 
of information we currently have indicates that the number of those 
entities, as well as CLFS payment amounts associated with them, are 
minimal. Based on 2013 claims data, we received only 21,627 claims for 
CLFS services from a total of 50 state or local public health clinics 
(0.1 percent of total labs that billed under the CLFS). However, we 
note that this proposed rule will potentially affect payments to a 
substantial number of laboratory test suppliers, and some effects may 
be significant.
2. Effects on the Medicare and Medicaid Programs
    The effect on the Medicare program is expected to be $360 million 
less in program payments for CLFS tests furnished in FY 2017. We first 
established a baseline difference between Medicare CLFS payment rates 
and private payor rates based on a study by the Office of Inspector 
General, ``Comparing Lab Test Payment Rates: Medicare Could Achieve 
Substantial Savings'', OEI-07-11-00010, June 2013. The OIG study showed 
that Medicare paid between 18 and 30 percent more than other insurers 
for 20 high-volume and/or high-expenditure lab tests. We assumed the 
private payor rates to be approximately 20 percent lower than the 
Medicare CLFS payment rates for all tests paid under the CLFS. We then 
accounted for the legislated 5 years of 1.75 percent cuts to laboratory 
payments, as required by section 1833(h)(2)(A)(iv)(II) of the Act, as 
well as 7 years of multi-factor productivity adjustments, as required 
by 1833(h)(2)(A) of the Act, to establish a new baseline difference 
between private payor rates and Medicare CLFS payment

[[Page 59417]]

rates of approximately 6.4 percent in 2017. The new baseline difference 
between Medicare CLFS payment rates and private payor rates (6.4 
percent) results in an approximate savings to the Medicare program of 
$360 million in FY 2017. We projected the FY 2017 Medicare savings of 
$360 million forward by assuming a rate of growth proportional to the 
growth in the CLFS (that is approximately 8.2 percent annually over the 
projection window FY 2016 through FY 2026) after adjusting for 
additional productivity adjustments to determine a 10 year cost savings 
estimate (as illustrated in Table 11). The effect on the Medicaid 
program is expected to be limited to payments that Medicaid may make on 
behalf of Medicaid recipients who are also Medicare beneficiaries. We 
note that section 6300.2 of the CMS State Medicaid Manual states that 
Medicaid reimbursement for CDLTs may not exceed the amount that 
Medicare recognizes for such tests.

E. Alternatives Considered

    This proposed rule contains a range of policies, including some 
provisions related to specific statutory provisions. The preceding 
sections of this proposed rule provide descriptions of the statutory 
provisions that are addressed, identify proposed policies where the 
statute recognizes the Secretary's discretion, present the rationale 
for our proposals and, where relevant, alternatives that were 
considered.
    In developing this proposed rule, we considered numerous 
alternatives to the presented proposals. Key areas where we considered 
alternatives include the organizational level associated with an 
applicable laboratory, authority to develop a low volume or low 
expenditure threshold to reduce reporting burden for small businesses, 
whether to include coinsurance amounts as part of the applicable 
information, the definition of the initial reporting period for ADLTs, 
and how to set rates for CDLTs for which the agency receives no 
applicable information. Below, we discuss alternative policies 
considered. We recognize that all of the alternatives considered could 
have a potential impact on the cost or savings under the CLFS. However, 
we do not have any private payor rate information with which to price 
these alternative approaches.
    Definition of applicable laboratory--TIN vs. NPI. We considered 
defining an applicable laboratory by NPI instead of TIN. As discussed 
in section II.A. of this proposed rule, we believe that defining an 
applicable laboratory for reporting applicable information to CMS by 
TIN, rather than by NPI, will result in the same applicable information 
being reported at a higher level and will require less reporting and 
will, therefore, be less burdensome to applicable laboratories. 
Therefore, we are proposing to define applicable laboratory by TIN 
rather than by NPI.
    Authority to develop a low volume or low expenditure threshold to 
reduce reporting burden for small businesses. We are proposing to 
exercise our authority to develop a low expenditure threshold to 
exclude small businesses from having to report applicable information. 
As discussed in section II.A. of this proposed rule, we are proposing 
that any entity that would otherwise be an applicable laboratory, but 
that receives less than $50,000 in Medicare revenues under section 
1834A and section 1833(h) of the Act for tests furnished during a data 
collection period, would not be an applicable laboratory. We considered 
the alternative of not proposing a low volume or low expenditure 
threshold which would require all entities meeting the definition of 
applicable laboratory to report applicable information to CMS. However, 
by proposing a low expenditure threshold we were able to substantially 
reduce the number of entities required to report applicable information 
to CMS (94 percent of physician office laboratories and 52 percent of 
independent laboratories would not be required to report applicable 
information) while retaining a high percentage of Medicare utilization 
(that is, 96 percent of CLFS spending on physician office laboratories 
and more than 99 percent of CLFS spending on independent laboratories) 
from applicable laboratories that would be required to report. We did 
not pursue a low volume threshold because it could potentially exclude 
laboratories that perform a low volume of very expensive tests from 
reporting applicable information. We believe that the proposed low 
expenditure threshold will significantly reduce the reporting burden 
for small businesses.
    Applicable information--Private payor rates inclusive of patient 
cost-sharing amounts (coinsurance, deductible) vs. private payor rates 
exclusive of patient cost-sharing amounts. As we discussed in section 
II.B. of this proposed rule, because Medicare generally does not 
require the beneficiary to pay a deductible or coinsurance on CLFS 
services, we believe it is important for private payor rates to be 
reported analogous to how they will be used by Medicare to determine 
the Medicare payment amount (that is, without any beneficiary cost-
sharing). For this reason, we are proposing that applicable 
laboratories report private payor rates inclusive of all patient cost 
sharing. We did not propose defining applicable information as private 
payor payment amounts after the application of beneficiary cost 
sharing, because reporting rates absent of deductible and coinsurance 
amounts would be inconsistent with how rates are determined under the 
CLFS.
    Definition of New ADLT Initial Period. As explained in sections 
II.C.1. and II.D.3 of this proposed rule, section 1834A(d)(1)(A) of the 
Act requires an ``initial period'' of three quarters during which 
payment for new ADLTs is based on the actual list charge for the 
laboratory test. The statute does not specify when this initial period 
of three quarters is to begin. Section 1834A(d)(2) of the Act requires 
reporting of applicable information not later than the last day of the 
Q2 of the initial period. These private payor rates will be used to 
determine the CLFS rate after the new ADLT initial period ends. We 
considered starting the initial period on the day the new ADLT is first 
performed (which in most cases would be after a calendar quarter 
begins). However, as noted previously in this proposed rule, if we were 
to start the initial period after the beginning of a calendar quarter, 
the 2nd quarter would also begin in the midst of a calendar quarter 
requiring the laboratory to report applicable information from the 
middle of the calendar quarter rather than on a calendar quarter basis. 
Further, if an initial period of three quarters would also end during a 
calendar quarter, the laboratory would start getting paid the weighted 
median rate in the middle of the calendar quarter rather at the 
beginning of a calendar quarter. This may be burdensome and confusing 
for laboratories. As such, we believe that the new ADLT initial period 
should start and end on the basis of a calendar quarter (for example, 
January 1 through March 31, April 1 through June 30, July 1 through 
September 30, or October 1 through December 31) for consistency with 
how private payor rates will be reported and determined for CDLTs (on 
the basis of a calendar year which is four quarters aggregated) and how 
CLFS rates will be paid (also on the basis of a calendar year).
    CMPs. With regard to CMPs, we are proposing to adopt a similar 
regulation for implementing section 1834A(a)(9)(A) of the Act that 
applies to drug manufacturers reporting Part B drug prices under 
section 1847A(d)(4) of the Act. We did not include in this proposed 
rule a specific proposal for

[[Page 59418]]

effecting CMPs under the proposed CLFS. Given that CMP collections have 
been limited for drug manufacturers (only one case), we do not have 
data to provide an estimate of CMP collections under the revised CLFS 
established under PAMA. Nevertheless, if compliance with the section 
1834A of the Act and this proposed rule is as high as occurred with 
reporting Part B drug prices, we expect CMP collections to be a rare 
event.
    Medicare payment for tests where no applicable information is 
reported. As discussed in section II.H.7. of this proposed rule, in the 
event we do not receive applicable information for a laboratory test 
that is provided to a Medicare beneficiary, we propose to use 
crosswalking and gapfilling using the proposed definitions in Sec.  
414.508(b)(1) and (2) to establish a payment rate on or after January 
1, 2017, which would remain in effect until the year following the next 
data reporting period. This policy would include the situation where we 
receive no applicable information for tests that were previously priced 
using gapfilling or crosswalking or where we had previously priced a 
test using the weighted median methodology. If CMS receives no 
applicable information in a subsequent data reporting period, we would 
use crosswalking or gapfilling methodologies to establish the payment 
amount for the test. In other words, if in a subsequent data reporting 
period, no applicable information is reported, CMS would reevaluate the 
basis for payment, of crosswalking or gapfilling, and the payment 
amount for the test. In exploring what we would do if we receive no 
applicable information for a CDLT, we alternatively considered carrying 
over the current payment amount for a test under the current CLFS, the 
payment amount for a test (if one was available) using the weighted 
median methodology based on applicable information from the previous 
data reporting period, or the gapfilled or crosswalked payment amount. 
However, we are not proposing this approach because we believe carrying 
over previous payment rates would not reflect changes in costs or 
pricing for the test over time. As noted in section II.H.7., we believe 
reconsidering payment rates for tests in these situations would be 
consistent with the purpose of section 1834A of the Act, which requires 
us to periodically reconsider CLFS payment rates.
    Cost of data reporting activities. As discussed in section II.D. of 
this proposed rule, applicable laboratories will be required to report 
applicable information to CMS. Section II.E.1. addresses penalties for 
non-reporting. We believe there could be substantial costs associated 
with compliance with section 1834A. As we do not have information upon 
which to develop a cost estimate for reporting applicable information, 
we cannot provide more information at this time. The CLFS has grown 
from approximately 400 tests to over 1,300 tests. While we are not able 
to ascertain how many private payors and private payor rates there are 
for each applicable laboratory, we are providing a hypothetical example 
to illustrate the number of records (with one record being the specific 
HCPCS code, the associated private payor rate, and volume) that an 
applicable laboratory would be required to report under this proposed 
rule. If an applicable laboratory had 30 different private payor rates 
for a given test and it received private payor payment for each test on 
the CLFS, it would be reporting 39,000 records (1,300 tests x 30) and 
117,000 data points (one data point each for the HCPCS code and its 
associated private payor rate and volume). Of course, this example is 
hypothetical and illustrative only but demonstrates the potential 
volume of information a given laboratory may be required to report. It 
seems likely that most applicable laboratories will not have private 
payor rates for each test on the CLFS and that a small number of tests 
will have the highest volume and more associated private payor rates. 
To the extent that a laboratory receives private payor payment for 
fewer than the 1,300 tests paid under the CLFS, the reporting burden 
will be less (and accordingly the 1,300 multiplier will be less) than 
in the above example. To the extent a private payor has more or less 
than 30 private payor rates, the multiplier will differ from 30 in the 
above example.
    To better understand the projected reporting, recordkeeping or 
other compliance requirements of the proposed rule, we are interested 
in public comments from applicable laboratories on the following 
questions:
     How many tests on the CLFS does the applicable laboratory 
perform?
     For each test, how many different private payor rates does 
the applicable laboratory have in a given period (for example, calendar 
year or other 12 month reporting period)?
     Does the applicable laboratory receive more than one rate 
from a private payor in a given period (for example, calendar year or 
other 12 month reporting period)?
     Is the information that laboratories are required to 
report readily available in the applicable laboratories' record 
systems?
     How much time does the applicable laboratory expect will 
be required to assemble and report applicable information?
     What kind of personnel will the applicable laboratory be 
using to report applicable information?
     What is the salary per hour for these staff?
     Is there other information not requested in the above 
questions that will inform the potential reporting burden being imposed 
by section 1834A of the Act?
    We believe that these items would be important factors to consider 
before projecting data reporting and or record keeping requirements. We 
welcome comments on these questions from the public.
    Phased-in Payment Reduction. As discussed in section II.H.2. of 
this proposed rule, we are proposing to use the NLAs for purposes of 
applying the 10 percent reduction limit to CY 2017 payment amounts 
instead of using local fee schedule amounts. As previously explained in 
section II.H.2., we believe the statute intends CLFS rates to be 
uniform nationwide, which is why it precludes any geographic 
adjustment. In other words, we are proposing that if the weighted 
median calculated for a CDLT based on applicable information for CY 
2017 would be more than 10 percent less than the CY 2016 NLA for that 
test, we would establish a Medicare payment amount for CY 2017 that is 
no less than 90 percent of the NLA (that is, no more than a 10 percent 
reduction). For each of CY 2018 through 2022, we would apply the 
applicable percentage reduction limitation to the Medicare payment 
amount for the preceding year. The alternative would be to apply the 10 
percent reduction limitation to the lower of the NLA or the local fee 
schedule amount. This option would retain some of the features of the 
current payment methodology. Under this option, though, the Medicare 
payment amounts may be local fee schedule amounts, so there could 
continue to be regional variation in the Medicare payment amounts for 
CDLTs. We believe that Medicare infrequently pays less than the NLA and 
there would be significant burden for CMS to establish systems logic to 
establish transition payment based on the less of the local fee 
schedule amount or the NLA. For this reason, and because we believe the 
statute intends there to be uniform national payment for CLFS services, 
we decided not to adopt this option.

F. Accounting Statement and Table

    As required by OMB Circular A-4 (available on the Office of 
Management and Budget Web site at: https://www.whitehouse.gov/sites/default/files/omb/assets/regulatory_matters_pdf/a-4.pdf), we have 
prepared an accounting statement in Table 11 to illustrate the impact 
of this proposed rule. The following table illustrates the estimated 
amount of change in CLFS spending under the proposed policies set forth 
in this proposed rule.

G. Cost to the Federal Government

    If these requirements are finalized, CMS will create a data 
collection system, develop HCPCS codes for laboratory tests when 
needed, convene a FACA advisory committee to make recommendations on 
how to pay for new CDLTs including reviewing and making recommendations 
on applications for ADLTs, and undertake other implementation 
activities. To implement these new standards, we anticipate initial 
federal start-up costs to be approximately $4 million. Once 
implemented, ongoing costs to collect data, review ADLTs, maintain data 
collection systems, and provide other upkeep and maintenance services 
will require an estimated $3 million annually in federal costs. We will 
continue to examine and seek comment on the potential impacts to both 
Medicare and Medicaid.

H. Conclusion

    The changes that we are proposing in this proposed rule would 
affect suppliers who receive payment under the CLFS, primarily 
independent laboratories and physician offices. We are limited in our 
ability to determine the specific impact on different classes of 
suppliers at this time due to the data limitations noted earlier in 
this section. However, we anticipate that the updated information 
through this proposed data collection process in combination with the 
exclusion of adjustments (geographic adjustment, budget neutrality 
adjustment, annual update, or other adjustment that may apply under 
other Medicare payment systems), as described in section 1834A(b)(4)(B) 
of the Act, will reduce aggregate payments made through the CLFS, and 
therefore, some supplier level payments. We note that this proposed 
rule includes proposed changes which may affect different laboratory 
test suppliers differently, based on the types of tests that they 
provide.
    The previous analysis, together with the remainder of this 
preamble, provides an initial Regulatory Flexibility Analysis. In 
accordance with the provisions of Executive Order 12866, this 
regulation was reviewed by the Office of Management and Budget.

* * * * *
    Actual list charge means the publicly available rate on the first 
day the new advanced diagnostic laboratory test (ADLT) is obtainable by 
a patient who is covered by private insurance, or marketed to the 
public as a test a patient can receive, even if the test has not yet 
been performed on that date.
    Advanced diagnostic laboratory test (ADLT) means a CDLT covered 
under Medicare Part B that is marketed and performed only by a single 
laboratory and not sold for use by a laboratory other than the 
laboratory that designed the test or a successor owner of that 
laboratory, and meets one of the following criteria:
    (1) The test--
    (i) Must be a molecular pathology analysis of multiple biomarkers 
of deoxyribonucleic acid (DNA), or ribonucleic acid (RNA);
    (ii) When combined with an empirically derived algorithm, yields a 
result that predicts the probability a specific individual patient will 
develop a certain condition(s) or respond to a particular therapy(ies);
    (iii) Provides new clinical diagnostic information that cannot be 
obtained from any other test or combination of tests; and
    (iv) May include other assays.
    (2) The test is cleared or approved by the Food and Drug 
Administration.
    Applicable information means, with respect to each CDLT for a data 
collection period--
    (1) Each private payor rate.
    (2) The associated volume of tests performed corresponding to each 
private payor rate.
    (3) The specific HCPCS code associated with the test.
    (4) Does not include information about a test for which payment is 
made on a capitated basis.
    Applicable laboratory means an entity that:
    (1) Reports tax-related information to the Internal Revenue Service 
(IRS) under a Taxpayer Identification Number (TIN) with which all of 
the National Provider Identifiers (NPIs) in the entity are associated,

    (a) General Rule: In a data reporting period, an applicable 
laboratory must report applicable information for each CDLT furnished 
during the corresponding data collection period, as follows--
    (1) For CDLTS that are not new CDLTs, every 3 years beginning 
January 1, 2016.
    (2) For ADLTs that are not new ADLTs, every year beginning January 
1, 2016.
    (3) For new ADLTs--
    (i) Initially, no later than the last day of the second quarter of 
the new ADLT initial period; and
    (ii) Thereafter, every year.
    (b) Applicable information must be reported in the form and manner 
specified by CMS.
    (c) A laboratory seeking new ADLT status for its test must, in its 
new ADLT application, attest to the actual list charge and the date the 
new ADLT is first performed.
    (d) To certify data integrity, the President, CEO, or CFO of an 
applicable laboratory or an individual who has been delegated authority 
to sign for, and who reports directly to, such an officer, must sign 
the certification statement and be responsible for assuring that the 
data provided are accurate, complete, and truthful, and meets all the 
reporting parameters described in this section.
    (e) If the Secretary determines that an applicable laboratory has 
failed to report, or made a misrepresentation or omission in reporting, 
applicable information, the Secretary may apply a civil monetary 
penalty in an amount of up to $10,000 per day for each failure to 
report or each such misrepresentation or omission. The provisions for 
civil monetary penalties that apply in general to the Medicare program 
under 42 U.S.C. 1320a-7b apply in the same manner to the laboratory 
data reporting process under this section.

7. Section 414.506 is amended by revising the introductory text and 
paragraph (d)(1), and adding paragraphs (d)(3), (d)(4), and (e) to read 
as follows:


Sec.  414.506  Procedures for public consultation for payment for a new 
clinical diagnostic laboratory test.

    For a new CDLT, CMS determines the basis for and amount of payment 
after performance of the following:
* * * * *
    (d) * * *
    (1) Proposed determinations with respect to the appropriate basis 
for establishing a payment amount for each code, with an explanation of 
the reasons for each determination, the data on which the 
determinations are based, including recommendations from the Advisory 
Panel on CDLTs described in paragraph (e), and a request for written 
public comments within a specified time period on the proposed 
determination; and
* * * * *
    (3) On or after January 1, 2017, in applying paragraphs (d)(1) and

8. Section 414.507 is added to read as follows:


Sec.  414.507  Payment for clinical diagnostic laboratory tests.

    (a) General rule. Except as provided in paragraph (d) of this 
section, and Sec.  414.508 and Sec.  414.522, the payment rate for a 
CDLT furnished on or after January 1, 2017, is equal to the weighted 
median for the test, as calculated under paragraph (b) of this section. 
Each payment rate will be in effect for a period of one calendar year 
for ADLTs and three calendar years for all other CDLTs, until the year 
following the next data collection period.
    (b) Methodology. For each test under paragraph (a) of this section 
for which applicable information is reported, the weighted median is 
calculated by arraying the distribution of all private payor rates, 
weighted by the volume for each payor and each laboratory.
    (c) The payment amounts established under this section are not 
subject to any adjustment, such as geographic, budget neutrality, 
annual update, or other adjustment.
    (d) Phase-in of payment reductions. For years 2017 through 2022, 
the payment rates established under this section for each CDLT that is 
not a new ADLT or new CDLT, may not be reduced by more than the 
following amounts for--
    (1) 2017--10 percent of the national limitation amount for the test 
in 2016.
    (2) 2018--10 percent of the payment rate established in 2017.
    (3) 2019--10 percent of the payment rate established in 2018.
    (4) 2020--15 percent of the payment rate established in 2019.
    (5) 2021--15 percent of the payment rate established in 2020.
    (6) 2022--15 percent of the payment rate established in 2021.
    (e) There is no administrative or judicial review under sections 
1869 and 1878 of the Social Security Act, or otherwise, of the payment 
rates established under this subpart.
    (f) Effective December 1, 2014, the nominal fee that would 
otherwise apply for a sample collected from an individual in a Skilled 
Nursing Facility (SNF) or by a laboratory on behalf of a Home Health 
Agency (HHA) is $5.
    (g) For a CDLT for which CMS receives no applicable information, 
payment is made based on the crosswalking or gapfilling methods 
described in Sec.  414.508(b)(1) and (2).
    (h) For ADLTs that are furnished between April 1, 2014 and December 
31, 2016, payment is made based on the crosswalking or gapfilling 
methods described in Sec.  414.508(a).

9. Section 414.508 is revised to read as follows:


Sec.  414.508  Payment for a new clinical diagnostic laboratory test.

    (a) For a new CDLT that is assigned a new or substantially revised 
code between January 1, 2005 and December 31, 2016, CMS determines the 
payment amount based on either of the following:
    (1) Crosswalking. Crosswalking is used if it is determined that a 
new CDLT is comparable to an existing test, multiple existing test 
codes, or a portion of an existing test code.
    (i) CMS assigns to the new CDLT code, the local fee schedule 
amounts and national limitation amount of the existing test.
    (ii) Payment for the new CDLT code is made at the lesser of the 
local fee schedule amount or the national limitation amount.
    (2) Gapfilling. Gapfilling is used when no comparable existing CDLT 
is available.
    (i) In the first year, Medicare Administrative Contractor-specific 
amounts are established for the new CDLT code using the following 
sources of information to determine gapfill amounts, if available:
    (A) Charges for the CDLT and routine discounts to charges;
    (B) Resources required to perform the CDLT;
    (C) Payment amounts determined by other payors; and
    (D) Charges, payment amounts, and resources required for other 
tests that may be comparable or otherwise relevant.
    (ii) In the second year, the test code is paid at the national 
limitation amount, which is the median of the contractor-specific 
amounts.
    (iii) For a new CDLT for which a new or substantially revised HCPCS 
code was assigned on or before December 31, 2007, after the first year 
of gapfilling, CMS determines whether the contractor-specific amounts 
will pay for the test appropriately. If CMS determines that the 
contractor-specific amounts will not pay for the test appropriately, 
CMS may crosswalk the test.
    (b) For a new CDLT that is assigned a new or substantially revised 
HCPCS code on or after January 1, 2017, CMS determines the payment 
amount based on either of the following until applicable information is 
available to establish a payment amount under the methodology described 
in Sec.  414.507(b):
    (1) Crosswalking. Crosswalking is used if it is determined that a 
new CDLT is comparable to an existing test, multiple existing test 
codes, or a portion of an existing test code.
    (i) CMS assigns to the new CDLT code, the payment amount 
established under Sec.  414.507 of the comparable existing CDLT.
    (ii) Payment for the new CDLT code is made at the payment amount 
established under Sec.  414.507.
    (2) Gapfilling. Gapfilling is used when no comparable existing CDLT 
is available.
    (i) In the first year, Medicare Administrative Contractor-specific 
amounts are established for the new CDLT code using the following 
sources of information to determine gapfill amounts, if available:
    (A) Charges for the test and routine discounts to charges;
    (B) Resources required to perform the test;
    (C) Payment amounts determined by other payors;
    (D) Charges, payment amounts, and resources required for other 
tests that may be comparable or otherwise relevant; and
    (E) Other criteria CMS determines appropriate.
    (ii) In the second year, the CDLT code is paid at the median of the 
Medicare Administrative Contractor-specific amounts.

10. Section 414.509 is amended by revising the introductory text and 
paragraphs (b)(2)(i) through (v) to read as follows:


Sec.  414.509  Reconsideration of basis for and amount of payment for a 
new clinical diagnostic laboratory test.

    For a new CDLT, the following reconsideration procedures apply:
* * * * *
    (b) * * *
    (2) * * *
    (i) By April 30 of the year after CMS makes a determination under 
Sec.  414.506(d)(2) or Sec.  414.509(a)(3) that the basis for payment 
for a CDLT will be gapfilling, CMS posts interim Medicare 
Administrative Contractor-specific amounts on the CMS Web site.
    (ii) For 60 days after CMS posts interim Medicare Administrative 
Contractor-specific amounts on the CMS Web site, CMS will receive 
public comments in written format regarding the interim Medicare 
Administrative Contractor-specific amounts.
    (iii) After considering the public comments, CMS will post final 
Medicare Administrative Contractor-specific amounts on the CMS Web 
site.
    (iv) For 30 days after CMS posts final Medicare Administrative 
Contractor-specific payment amounts on the CMS Web site, CMS will 
receive reconsideration requests in written format regarding whether 
CMS should reconsider the final Medicare Administrative Contractor-
specific payment amount and median of the Medicare Administrative 
Contractor-specific payment amount for the CDLT.
    (v) Considering reconsideration requests received, CMS may 
reconsider its determination of the amount of payment. As the result of 
a reconsideration, CMS may revise the median of the Medicare 
Administrative Contractor-specific payment amount for the CDLT.

11. Section 414.522 is added to subpart G to read as follows:


Sec.  414.522  Payment for new advanced diagnostic laboratory tests.

    (a) The payment rate for a new ADLT--
    (1) During the new ADLT initial period, is equal to its actual list 
charge.
    (2) Prior to the new ADLT initial period, is determined by the 
Medicare Administrative Contractor based on information provided by the 
laboratory seeking new ADLT status for its laboratory test.
    (b) After the new ADLT initial period, the payment rate for a new 
ADLT is equal to the weighted median established under the payment 
methodology described in Sec.  414.507(b).
    (c) If, after the new ADLT initial period, the difference between 
the actual list charge of a new ADLT and the weighted median 
established under the payment methodology described in Sec.  414.507 
exceeds 130 percent, CMS will recoup the entire amount of the 
difference between the ADLT actual list charge and the weighted median.
    (d) If CMS does not receive any applicable information for a new 
ADLT by the last day of the second quarter of the new ADLT initial 
period, the payment rate for the test is determined either by the 
gapfilling or crosswalking method as described in Sec.  414.508(b)(1) 
and (2).
