SUPPLEMENTARY INFORMATION: VA published a proposed rule in the Federal 
Register at 80 FR 46888 on August 6, 2015, to amend the portion of the 
VASRD dealing with the hematologic and lymphatic systems. VA provided a 
60-day public comment period and invited interested persons to submit 
written comments, suggestions, or objections on or before October 5, 
2015. VA received 11 comments.

I. Purpose of the Final Rule

    VA revises the section of the VASRD that addresses the hematologic 
and lymphatic systems. This final rule updates medical terminology, 
adds certain hematologic diseases, and provides detailed and updated 
criteria for evaluating conditions pertaining to the hematologic and 
lymphatic systems.

II. Technical Corrections

    In the proposed rule, VA proposed a new diagnostic code (DC) 7720, 
Iron deficiency anemia. In its review of the final rule, VA realized 
that the proposed text for 10 percent disability rating contained an 
error. Namely, VA required continuous treatment with high-dose oral 
supplementation for a 10 percent disability rating, rather than 
intravenous iron infusions at least 1 time but less than 4 times per 
12-month period, or continuous treatment with oral supplementation. 
This document corrects this error by amending the proposed text to read 
as follows: ``Requiring intravenous iron infusions at least 1 time but 
less than 4 times per 12-month period, or requiring continuous 
treatment with oral supplementation.'' The proposed rule specified that 
a zero-percent rating would be warranted if the condition is 
asymptomatic or treatable by dietary restrictions only. Implicit in the 
proposed rule was the premise that, if the condition requires 
intravenous treatment less often than required for a 30-percent rating, 
then a 10 percent rating would be warranted. This final rule makes that 
premise explicit in DC 7720.
    In the proposed rule, VA introduced amended criteria for the 100 
percent evaluation in DC 7702 based on the requirement for bone marrow 
transplant or infections recurring at least once every six weeks per 
12-month period. Upon further review, VA inadvertently omitted a 
semicolon between these two criteria, which could lead to confusion as 
to the application of the 100 percent criteria. To clarify that these 
two criteria are separate and distinct and that only one is required to 
establish a 100 percent evaluation, VA is inserting a semicolon after 
``transplant'';
    In the proposed rule, VA introduced criteria for DCs 7714, 7720, 
7723, and 7725 which measured the occurrence of infections (7725), 
painful episodes (7714), transfusions (7725), infusions (7720), or 
medication usage (7723) based on the ``average'' number of episodes per 
12-month period. Upon further review, VA determined that including 
``average'' in calculating the number of episodes required by the given 
criteria will result in unclear guidance and inconsistent application 
of the VASRD, in direct conflict with one of the stated goals of the 
VASRD revisions. Additionally, references to the average number of 
episodes per 12-month period might suggest that evaluations should in 
all instances be based on the average frequency of the episodes over an 
unspecified number of years. Although VA must evaluate conditions ``in 
relation to [their] history,'' 38 CFR 4.1, there may be instances where 
there has been a discernible change in the severity of a condition and 
it is more appropriate to evaluate the disability primarily on current 
manifestations than on an average of the manifestations over a number 
of prior years. Accordingly, to increase consistency in the application 
of the criteria, promote clarity in the requirements for each 
evaluation level, and to ensure that evaluations may reflect changes in 
a condition's severity and the frequency of episodes, VA will remove 
the reference to ``average'' from the criteria in DCs 7714, 7720, 7723, 
and 7725 and replace it with a quantifiable range at each criteria 
level. This change to the language does not result to any substantive 
changes to the criteria in the identified DCs.
    Additionally, in DC 7705, VA inadvertently omitted semicolons 
between these distinct criteria in the 100, 70, and 0 percent 
evaluations, which could lead to confusion as to the application of 
these evaluation levels. To reiterate and clarify that the criteria in 
these evaluation levels are separate and distinct, and that only one is 
required to establish a given evaluation, VA is inserting a semicolon 
between the criteria for clarification purposes. No substantive change 
to the evaluation criteria results from this change.
    In the proposed rule, VA introduced several changes to DC 7704, 
Polycythemia vera, including a revision for a 30 percent disability 
rating. Namely, for a 30 percent disability rating, VA required 
phlebotomy 4-5 times per 12-month period or continuous biologic therapy 
or myelosuppressive agents to maintain platelets <200,000 or white 
blood cells (WBC) <12,000. VA would like to clarify that 
myelosuppressive agents, which are used to maintain platelets <200,000 
or white blood cells (WBC) <12,000, include interferon. This document 
includes this clarification by amending the proposed text to read as 
follows: ``Requiring phlebotomy 4-5 times per 12-month period, or if 
requiring continuous biologic therapy or myelosuppressive agents, to 
include interferon, to maintain platelets <200,000 or white blood cells 
(WBC) <12,000.'' VA also makes a clarifying change in the proposed text 
for 60 percent disability amending the reference to ``targeted agents 
such as imatinib or ruxolitinib'' to ``molecularly targeted therapy,'' 
which includes imatinib, ruxolitinib, and other agents. Upon further 
review, VA has determined that including the ``chemotherapy'' reference 
in the evaluation criteria at both the 60 percent and 100 percent 
levels in the proposed rule would create a conflict such that the 
criteria could not be applied consistently and accurately, potentially 
resulting in over- and under-evaluation. Accordingly, to increase 
consistency in the application of the criteria, promote clarity in the 
requirements for each evaluation level, and to ensure the VASRD 
criteria do not conflict with the guidance set forth in Note 3, VA will 
remove the reference to ``chemotherapy'' from the criteria in proposed 
DC 7704 for the 60 percent rating criteria. Because the requirement for 
chemotherapy supports a 100 percent rating, this change to the criteria 
for the lower 60 percent rating will not affect any claims but will 
eliminate potential confusion. Additionally, VA made an editorial 
change to the proposed language. Namely, VA clarified the 60 percent 
disability rating criteria to read as follows: ``Requiring phlebotomy 6 
or more times per 12-month period or molecularly targeted therapy for 
the purpose of controlling RBC count.'' This change to the language 
does not result in any substantive changes to the criteria in the 
identified DC.
    VA also corrects the spelling of ``myelosuppressive,'' which was 
misspelled in the proposed regulatory text.
    Additionally, VA realized that the proposed text for 10 percent 
disability rating under DC 7704 contained a grammatical error that 
would have made the rule more confusing and difficult to apply than VA 
intended. Namely, VA identified a 10 percent disability rating in the 
proposed rule as: ``Requiring phlebotomy, biologic therapy, or 
interferon on an intermittent basis, as needed, 3 or fewer times per 
12-month

[[Page 54252]]

period.'' VA did not intend to apply two different frequency 
standards--i.e., ``on an intermittent basis'' and ``3 or fewer times 
per 12-month period''--to the same events, but the proposed text could 
suggest that both standards apply to each of the listed events. Rather, 
consistent with the requirements for the 60 percent and 30 percent 
ratings, VA intended that the ``3 or fewer times per 12-month period'' 
requirement would apply only to phlebotomy, and that the ``on an 
intermittent basis'' requirement would apply to the other listed 
treatments. In order to increase consistency in the application of the 
criteria and promote clarity in the requirements for each evaluation 
level, VA has included additional reference to the outcome of the 
treatment for polycythemia vera for 10 percent and 100 percent 
evaluation levels. This document corrects the above-referenced 
grammatical error and includes additional guidance by amending the 
proposed text for 10 percent evaluation to read as follows: ``Requiring 
phlebotomy 3 or fewer times per 12-month period or if requiring 
biologic therapy or interferon on an intermittent basis as needed to 
maintain all blood levels at reference range levels.'' Additionally, VA 
amends the proposed text for 100 percent evaluation to read as follows: 
``Requiring peripheral blood or bone marrow stem-cell transplant or 
chemotherapy (including myelosuppressants) for the purpose of 
ameliorating the symptom burden.''
    In the proposed rule, VA proposed several changes to DC 7705, 
including criteria based on platelet counts. VA specifically proposed 
to assign a 100 percent evaluation for platelet count below 30,000. 
However, for the 70 percent criteria, which apply in circumstances 
involving a platelet count higher than 30,000, VA omitted criteria for 
when platelet count is at 30,000. Accordingly, VA has changed the 100 
percent criteria to read ``platelet count 30,000 or below'' to avoid a 
gap in the platelet count range considered in the evaluation criteria.
    In the proposed rule, VA introduced several changes to DC 7716, 
Aplastic anemia, including a revision for a 60 percent disability 
rating. Namely, for a 60 percent rating, VA required the use of 
continuous immunosuppressive therapy. In order to capture the full 
range of therapeutic agents that are used to treat this condition, VA 
makes a clarifying change that amends the proposed text to reference 
the use of ``newer platelet stimulating factors'' in the evaluation 
criteria. Additionally, VA has added an explanatory note (2) regarding 
the definition of ``newer platelet stimulating factors'' for 
clarification purposes and redesignated the existing note as note (1).
    In the proposed rule, VA introduced several changes to DC 7718, 
Essential thrombocythemia and primary myelofibrosis, including 
revisions for 70 and 30 percent disability ratings. Namely, for 70 and 
30 percent ratings, VA required the use of continuous or intermittent 
myelosuppressive therapy. In order to capture the full range of 
therapeutic agents that are used to treat these conditions, VA makes a 
clarifying change that amends the proposed text for 70 percent 
disability rating to read as follows: ``Requiring continuous or 
intermittent myelosuppressive therapy, or chemotherapy, or interferon 
treatment to maintain platelet count < 500 x 10\9\/L.'' VA makes a 
clarifying change that amends the proposed text for 30 percent 
disability rating to read as follows: ``Requiring continuous or 
intermittent myelosuppressive therapy, or chemotherapy, or interferon 
treatment to maintain platelet count of 200,000-400,000, or white blood 
cell (WBC) count of 4,000-10,000.''
    In the proposed rule, VA introduced several changes to DC 7719, 
Chronic myelogenous leukemia (CML) (chronic myeloid leukemia or chronic 
granulocytic leukemia), including revisions for 60 and 30 percent 
disability ratings. Namely, for 60 and 30 percent ratings, VA required 
the use of targeted therapy with tyrosine kinase inhibitors. In order 
to capture the full range of targeted therapy agents that are used to 
treat these conditions, VA makes a clarifying change that amends the 
proposed text for 60 percent disability rating to read as follows: 
``Requiring intermittent myelosuppressive therapy, or molecularly 
targeted therapy with tyrosine kinase inhibitors, or interferon 
treatment when not in apparent remission.'' VA makes a clarifying 
change that amends the proposed text for 30 percent disability rating 
to read as follows: ``In apparent remission on continuous molecularly 
targeted therapy with tyrosine kinase inhibitors.''

III. Public Comments

    One commenter asked why the hematological system did not include 
Lyme disease. Lyme disease is an infectious disease evaluated under 38 
CFR 4.88b. DC 6319 specifically addresses Lyme disease and its 
residuals. Therefore, VA makes no changes based on this comment.
    One commenter urged VA to include in the rating schedule the 
debilitating side effects of daily tyrosine kinase inhibitors (TKIs) 
therapy for chronic myelogenous leukemia (CML). In the proposed rule, 
DC 7719 assigns a 60 percent evaluation for intermittent 
myelosuppressive therapy, or targeted therapy with TKIs, such as 
ruxolitinib, and a 100 percent evaluation for continuous 
myelosuppressive or immunosuppressive therapy. However, in cases of 
debilitating side effects of therapy for a service-connected disease, 
such as CML, VA may grant service connection on a secondary basis for 
disabilities that are proximately due to, or aggravated by, service-
connected disease or injury pursuant to 38 CFR 3.310. Therefore, VA 
makes no changes based on this comment.
    Another commenter suggested separating evaluations for pernicious 
anemia from evaluations for Vitamin B12 deficiency anemia. 
Pernicious anemia is caused by too little Vitamin B12; it is 
one form of Vitamin B12 deficiency anemia. VA recognizes the 
importance of separating pernicious anemia from Vitamin B12 
deficiency anemia for diagnosis and treatment. However, for disability 
compensation, VA evaluates common signs and symptoms and functional 
impairment of Vitamin B12 deficiency, also seen in 
pernicious anemia, under one diagnostic code. Therefore, VA makes no 
changes based on this comment.
    The same commenter noted that anemia secondary to autoimmune 
pernicious anemia is not corrected but maintained by Vitamin 
B12 injections. VA agrees. In the proposed rule, DC 7722 
provides a 10 percent evaluation for pernicious anemia and other forms 
of severe Vitamin B12 deficiency if it requires continuous 
treatment with Vitamin B12 injections, Vitamin 
B12 sublingual or high-dose oral tablets, or Vitamin 
B12 nasal spray or gel. Therefore, VA makes no changes based 
on this comment.
    The same commenter suggested including all body systems sequelae of 
pernicious anemia into hematologic system evaluations. In cases when 
debilitating effects of pernicious anemia affect other body systems, VA 
may grant service connection on a secondary basis for disabilities that 
are proximately due to, or aggravated by, service-connected disease or 
injury, pursuant to 38 CFR 3.310. Therefore, VA makes no changes based 
on this comment.
    The same commenter suggested VA conduct a study to determine 
whether the degree of neurologic or gastrointestinal residuals 
correlates with treatment variations. While VA appreciates this 
comment, it is beyond the scope of this rulemaking. Therefore, VA makes 
no changes based on it.

[[Page 54253]]

    The same commenter expressed concern regarding the application of 
38 CFR 3.105(e), which governs reduction in evaluation, to evaluate the 
debilitating residual effects of pernicious anemia. However, VA may 
grant service connection on a secondary basis for disabilities that are 
proximately due to, or aggravated by, service-connected disease or 
injury pursuant to 38 CFR 3.310. Therefore, VA makes no changes based 
on this comment.
    One commenter discussed his current treatment for chronic myeloid 
leukemia and its side effects. The commenter did not offer any specific 
suggestions or recommendations for this rulemaking. Therefore, VA makes 
no changes based on this comment.
    Another commenter urged the Federal Communications Commission (FCC) 
to reconsider regulating open-source software. This comment is beyond 
the scope of this rulemaking, so VA makes no changes based on it.
    Two commenters indicated that security and privacy issues are 
important to them. The commenters did not offer any specific 
suggestions or recommendations for this rulemaking. Therefore, VA makes 
no changes based on these comments.
    One commenter discussed his brother's diagnosis of chronic myeloid 
leukemia and military service in Vietnam. The commenter did not offer 
any specific suggestions or recommendations for this rulemaking. 
Therefore, VA makes no changes based on this comment.
    Another commenter discussed his diagnosis of chronic myeloid 
leukemia, its side effects, and his military service in Vietnam. The 
commenter expressed his satisfaction with updates to the hematologic 
section of the rating schedule, which includes evaluations for chronic 
myeloid leukemia. The commenter did not offer any specific suggestions 
or recommendations for this rulemaking. Therefore, VA makes no changes 
based on this comment.
    One commenter was supportive of many of the changes and additions 
made to the hematologic and lymphatic sections of the VASRD, which 
include new diagnostic codes for common disorders, clarifying notes on 
residuals affecting other body systems, and recognizing common side 
effects of various treatments. The commenter offered two minor 
suggestions regarding rating criteria for multiple myeloma (DC 7712) 
and acquired hemolytic anemia (DC 7723).
    The commenter suggests deleting Note 2, Note 3, and part of Note 1 
under DC 7712 in order to simplify the rating process. VA agrees and 
removes the references to specific laboratory values by deleting Note 
(2) and Note (3). VA edits Note (1) by removing the references to 
specific laboratory values and replaces them with more general 
references to what are acceptable for the diagnosis of multiple myeloma 
as defined by the American Society of Hematology (ASH) and 
International Myeloma Working Group. Lastly, VA renumbers the proposed 
Note (4) to become Note (2).
    The same commenter suggested including two additional treatment 
modalities for acquired hemolytic anemia under DC 7723. The commenter 
noted that, according to guidelines of the National Institutes of 
Health, the National Heart, Lung, and Blood Institute, and ASH, 
treatments for symptomatic acquired hemolytic anemia may include blood 
transfusion or plasmapheresis. VA identifies four levels of disability 
for symptomatic acquired hemolytic anemia, each of which includes blood 
transfusion or plasmapheresis. The defining feature for each level of 
disability is the frequency of immunosuppressive therapy or the need 
for a bone marrow transplant. Therefore, VA makes no changes based on 
this comment.
    Another commenter noted that further revisions are needed for 
hematologic and lymphatic section of the VASRD to ensure its congruency 
with current understanding of hematologic diseases. The commenter 
offered multiple recommendations on selected diagnostic codes.
    The commenter recommended deleting the references to obsolete or 
never used treatments. VA agrees and removes all references to 
treatment with radioactive phosphorus (DCs 7704, 7718, 7719, and 7725), 
imantib (DC 7704), interferon alpha (DC 7725), and multiple references 
to outdated laboratory values under DCs 7705 and 7712, Note (1). 
Proposed DC 7705 referred to a platelet count range from 20,000 to 
30,000 despite treatment under a 100-percent rating level. The final 
rule revises this value to include all platelet counts of 30,000 or 
below.
    The commenter noted that various anemia sections (DCs 7714, 7716, 
7720, 7722, and 7723) did not link to comorbidities, such as cardiac 
disease and chronic obstructive pulmonary disease. The commenter 
advised VA to revise anemia DCs to include comorbidities because 
different hemoglobin levels might have vastly different implications in 
patients with cardiac disease, chronic obstructive pulmonary disease, 
or other significant comorbid conditions. As the hematopoietic system 
supports other cells or organs of the body, VA assigns disability 
ratings resulting from identifiable defects in these organs due to 
hematologic disease. The hematologic rating does not generally include 
the physiologic effects on the function of other end-organs. For 
example, very severe anemia can reduce oxygen delivery to the point 
where the individual suffers a myocardial infarction. The disability 
ratings for both the anemia and the myocardial infarction would be 
rated separately and then combined. VA may grant service connection on 
a secondary basis for disabilities that are proximately due to, or 
aggravated by, service connected disease or injury pursuant to 38 CFR 
3.310. Therefore, VA makes no changes based on this comment.
    The commenter noted that current practice infrequently transplants 
bone marrow to treat agranulocytosis (DC 7702). Additionally, current 
medical protocol never uses platelet and red cell transfusions. Even 
though use of bone marrow transplants may be infrequent, the fact that 
it is still used for cases that do not respond to other types of 
treatment justifies including it as part of the 100 percent rating 
criteria. Additionally, the proposed rule does not refer to platelet 
and red cell transfusions for the treatment of agranulocytosis. 
Therefore, VA makes no changes based on this comment.
    The commenter indicated that current practice does not use 
radioactive phosphorus or interferon alpha to treat myelodysplastic 
syndromes (DC 7725). VA agrees and removes all references to such 
treatment from this DC.
    The commenter suggested editing platelet count reference for a 100 
percent evaluation under DC 7705, Immune thrombocytopenia. ASH 
guidelines for immune thrombocytopenia recommend treatment for patients 
with platelet counts below 30,000. VA agrees and replaces the reference 
to ``a platelet count from 20,000 to 30,000'' under DC 7705 with ``a 
platelet count 30,000 or below despite treatment''.
    The commenter noted that the 100 percent evaluation under DC 7705 
included chemotherapy but the relevance of immunosuppressive therapy to 
this evaluation was unclear. However, VA did not intend to include 
immunosuppressive therapy as part of a 100 percent evaluation. VA 
includes immunosuppressive therapy as part of a 70 percent evaluation. 
Therefore, VA makes no changes based on this comment.
    The commenter noted that recent advances in medicine have 
identified

[[Page 54254]]

conditions called monoclonal gammopathy of undetermined significance 
(MGUS) and smoldering myeloma, which are not acute myeloma but may 
indicate a future need for treatment. The commenter suggested removing 
an outdated reference to indolent myeloma from DC 7712 and replacing it 
with MGUS. VA agrees and removes the reference to indolent myeloma from 
DC 7712 and replaces the reference with MGUS.
    VA appreciates the comments submitted in response to the proposed 
rule. Based on the rationale stated in the proposed rule and in this 
document, the final rule is adopted with the changes noted.
    We are additionally adding updates to 38 CFR part 4, Appendices A, 
B, and C, to reflect changes to the hematologic and lymphatic systems 
rating criteria made by this rulemaking. VA designs the appendices for 
users of the VASRD. They do not contain substantive content regarding 
disability evaluations.

Executive Orders 12866, 13563 and 13771

    Executive Orders 12866 and 13563 direct agencies to assess the 
costs and benefits of available regulatory alternatives and, when 
regulation is necessary, to select regulatory approaches that maximize 
net benefits (including potential economic, environmental, public 
health and safety effects, and other advantages; distributive impacts; 
and equity). Executive Order 13563 (Improving Regulation and Regulatory 
Review) emphasizes the importance of quantifying both costs and 
benefits, reducing costs, harmonizing rules, and promoting flexibility. 
Executive Order 12866 (Regulatory Planning and Review) defines a 
``significant regulatory action'' requiring review by the Office of 
Management and Budget (OMB), unless OMB waives such review, as ``any 
regulatory action that is likely to result in a rule that may: (1) Have 
an annual effect on the economy of $100 million or more or adversely 
affect in a material way the economy, a sector of the economy, 
productivity, competition, jobs, the environment, public health or 
safety, or State, local, or tribal governments or communities; (2) 
Create a serious inconsistency or otherwise interfere with an action 
taken or planned by another agency; (3) Materially alter the budgetary 
impact of entitlements, grants, user fees, or loan programs or the 
rights and obligations of recipients thereof; or (4) Raise novel legal 
or policy issues arising out of legal mandates, the President's 
priorities, or the principles set forth in this Executive Order.''
    The economic, interagency, budgetary, legal, and policy 
implications of this regulatory action have been examined, and it has 
been determined not to be a significant regulatory action under 
Executive Order 12866. VA's impact analysis can be found as a 
supporting document at https://www.regulations.gov, usually within 48 
hours after the rulemaking document is published. Additionally, a copy 
of this rulemaking and its impact analysis are available on VA's 
website at https://www.va.gov/orpm/, by following the link for ``VA 
Regulations Published From FY 2004 Through Fiscal Year to Date.''
    This rule is not an Executive Order 13771 regulatory action because 
this rule is not significant under Executive Order 12866.

Regulatory Flexibility Act

    The Secretary hereby certifies that this final rule will not have a 
significant economic impact on a substantial number of small entities 
as defined in the Regulatory Flexibility Act, 5 U.S.C. 601-612. This 
final rule will not affect any small entities. Only certain VA 
beneficiaries could be directly affected. Therefore, pursuant to 5 
U.S.C. 605(b), this rulemaking is exempt from the initial and final 
regulatory flexibility analysis requirements of sections 603 and 604.

Unfunded Mandates

    The Unfunded Mandates Reform Act of 1995 requires, at 2 U.S.C. 
1532, that agencies prepare an assessment of anticipated costs and 
benefits before issuing any rule that may result in the expenditure by 
State, local, and tribal governments, in the aggregate, or by the 
private sector, of $100 million or more (adjusted annually for 
inflation) in any one year. This final rule will have no such effect on 
State, local, and tribal governments, or on the private sector.

Paperwork Reduction Act

    This final rule contains provisions constituting a collection of 
information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-
3521). Specifically, this final rule is associated with information 
collections related to the filing of disability claims (VA Form 21-
526EZ) as well as Disability Benefits Questionnaires (DBQs) which 
enable a claimant to gather the necessary information from his or her 
treating physician as to the current symptoms and severity of a 
disability. Both information collections are currently approved by the 
Office of Management and Budget (OMB) and have been assigned OMB 
control Numbers 2900-0749 and 2900-0779, respectively. There are no 
changes to any of these information collections and, thus, no 
incremental costs associated with this rulemaking.
