SUMMARY: The Department of Veterans Affairs (VA) proposes to revise the 
portion of the VA Schedule for Rating Disabilities (Rating Schedule) 
that addresses the endocrine system. The intended effects of these 
changes are to update medical terminology, add medical conditions not 
currently in the Rating Schedule, revise the criteria to reflect 
medical advances since the last revision in 1996, and clarify the 
criteria.

DATES: Comments must be received by VA on or before September 8, 2015.

ADDRESSES: Written comments may be submitted through 
www.Regulations.gov; by mail or hand-delivery to the Director, 
Regulations Policy and Management (02REG), Department of Veterans 
Affairs, 810 Vermont Avenue NW., Room 1068, Washington, DC 20420; or by 
fax to (202) 273-9026. Comments should indicate that they are submitted 
in response to ``RIN 2900-AO44-Schedule for Rating Disabilities--The 
Endocrine System.'' Copies of comments received will be available for

SUPPLEMENTARY INFORMATION: As part of the ongoing revision of the VA 
Schedule for Rating Disabilities (``Rating Schedule''), VA is proposing 
changes to 38 CFR 4.119, Schedule of ratings-endocrine system. This 
section was last updated in 1996. The endocrine system is made up of 
multiple hormone-producing glands. Hormones are chemical messengers 
that control the function of many body processes. While the actual 
dysfunction occurs at the site of the gland, the signs and symptoms 
manifest in the body systems on which the specific hormones act. For 
diagnosis and acute management of endocrine diseases, medical 
professionals focus on addressing the problem within the endocrine 
system. However, the residual effects of an endocrine disease may 
manifest within multiple body systems. Therefore, in general, VA 
proposes specific criteria for the initial rating of endocrine diseases 
within Sec.  4.119 to account for the unique functional impairments 
associated with attempts to bring the condition under control. Once the 
condition is effectively managed or has reached maximal medical 
outcome, VA proposes to evaluate for the residual effects of disease 
within the appropriate (adversely impacted) body system. For rating 
clarity, the most commonly impacted systems would be referenced within 
the specific diagnostic code (DC). By the revisions discussed herein, 
VA aims to update medical terminology, add medical conditions not 
currently in the Rating Schedule, revise the criteria to reflect 
medical advances, and clarify the criteria.
    In preparing this proposed revision, VA conducted a mini-summit in 
Washington, DC, on December 2, 2009. VA also researched current medical 
information and consulted with Veterans Health Administration (VHA) 
subject matter experts.

DC 7900: Hyperthyroidism, Including, But Not Limited to, Graves' 
Disease

    VA proposes to update the title of DC 7900. Currently, this DC is 
titled ``Hyperthyroidism.'' The most common cause of hyperthyroidism is 
Graves' disease, an autoimmune disease that affects multiple organ 
systems, including the eyes and skin. ``Hyperthyroidism (overactive 
thyroid),'' Mayo Clinic, https://www.mayoclinic.com/health/hyperthyroidism/DS00344/DSECTION =causes. Given the prevalence of 
hyperthyroidism due to Graves' Disease, VA proposes to explicitly 
recognize Graves' disease under this DC by changing the title of DC 
7900 from ``Hyperthyroidism'' to ``Hyperthyroidism, including, but not 
limited to, Graves' disease.'' This is not a substantive change, but 
simply an effort to increase rating efficiency. To account for less 
common causes of hyperthyroidism not addressed by other DCs, VA does 
not propose to limit this DC so that it is only applicable to Graves' 
disease.
    Hyperthyroidism refers to the excess synthesis or secretion of 
thyroid hormone. Regardless of the specific cause, the symptoms 
directly caused by excess thyroid hormone are the same. Therefore, VA 
proposes to evaluate the disability associated with excess thyroid 
hormone using a single set of rating criteria that reflects an earlier 
diagnosis and current treatment options. Medical advances have 
facilitated earlier diagnosis and treatment of hyperthyroidism. 
Treatment is directed at symptom relief and includes antithyroid 
medications, radioactive iodine therapy, and thyroidectomy (surgical 
removal of the thyroid gland). Earlier treatment has decreased the 
duration and severity of both acute and chronic symptoms of 
hyperthyroidism, as well as its disabling residual effects. Therefore, 
the existing evaluations of 100 and 60 percent for this condition are 
no longer appropriate and VA proposes to no longer assign them.
    In the majority of cases, by the time patients present with the 
symptoms currently reflected in the criteria for a 30 percent 
evaluation (tachycardia, tremor, and increased blood pressure or pulse 
pressure), treatment is initiated. With treatment, these symptoms 
generally resolve completely within three to six months. Therefore, VA 
proposes to evaluate hyperthyroidism at 30 percent for six months after 
initial diagnosis. Because symptoms generally resolve completely while 
the 30 percent evaluation is applicable, VA also proposes to no longer 
assign a 10 percent evaluation. To account for symptoms that do not 
resolve completely within six months, VA proposes adding a directive 
instructing VA personnel to ``rate residuals of disease or 
complications of medical treatment . . . within the appropriate body 
system.''
    Since cardiovascular abnormalities are common in hyperthyroidism, 
and some persist despite treatment with antithyroid medications, VA 
proposes an alternative to the current approach which rates certain 
cardiovascular manifestations within DC 7900 but refers VA personnel to 
DC 7008 (hyperthyroid heart disease) if heart disease is the 
predominant disability (see current Note (1)). Hyperthyroidism is 
associated with a variety of cardiovascular problems including 
tachycardia, systolic hypertension, cardiac arrhythmias particularly 
atrial fibrillation, supraventricular tachycardia, congestive heart 
failure or angina among others. See Faizel Osman et al., 
``Cardiovascular manifestations of hyperthyroidism before and after 
antithyroid therapy,'' 49 (1) J. Am. College of Cardiology, 71-81 
(2007). In order to address more specifically cardiovascular issues 
related to hyperthyroidism, VA proposes to modify the existing Note (1) 
to state that if cardiovascular or cardiac problems related to 
hyperthyroidism are present separately evaluate under DC 7008.
    In order to clarify a potentially confusing element in DC 7008 that 
directs hyperthyroid heart disease to be part of the overall evaluation 
of hyperthyroidism under DC 7900, VA

[[Page 39013]]

proposes to amend DC 7008 by directing that hyperthyroid heart disease 
be rated under the appropriate cardiovascular diagnostic code, 
depending on particular findings.
    Currently, DC 7008 states that only when atrial fibrillation is 
present hyperthyroidism may be evaluated either under DC 7900 or under 
7010 (supraventricular arrhythmia), whichever results in a higher 
evaluation. As described above, the potential cardiovascular conditions 
related to hyperthyroidism are numerous and complex, and the current 
approach limits the alternatives and precludes optimal assessment in 
instances other than for atrial fibrillation.
    Currently, Note (2) of DC 7900 states: ``If ophthalmopathy is the 
sole finding, evaluate as field vision, impairment of (DC 6080); 
diplopia (DC 6090); or impairment of central visual acuity (DC 6061-
6079).'' In the case of Graves' disease, which is evaluated under 
proposed DC 7900, eye abnormalities can occur independently and in the 
absence of hyperthyroidism. As such, it is not appropriate to limit 
evaluation of such manifestations under either DC 7900 or an 
appropriate DC within the eye body system. VA therefore proposes to 
revise current Note (2) to read: Separately evaluate eye involvement 
occurring as a manifestation of Graves' Disease as diplopia (DC 6090); 
impairment of central visual acuity (DCs 6061-6066); or under the most 
appropriate DCs in Sec.  4.79.

DC 7901: Thyroid Enlargement, Toxic

    VA proposes to update the title of DC 7901 from ``Thyroid gland, 
toxic adenoma of'' to ``Thyroid enlargement, toxic.'' When discussing 
thyroid enlargement, ``toxic'' is the term used by the medical 
community to indicate overactive thyroid function, also known as 
hyperthyroidism. Currently, the rating criteria accompanying this DC 
are identical to that accompanying current DC 7900. Therefore, rather 
than repeating the criteria for hyperthyroidism, VA proposes Note (1) 
to direct raters to evaluate toxic thyroid enlargement under proposed 
DC 7900 (hyperthyroidism, including, but not limited to, Graves' 
disease).
    An enlarged thyroid may cause a visible swelling at the base of the 
neck or thyroidectomy may result in disfigurement. To account for such 
disfigurement, VA proposes Note (2) directing VA personnel: If 
disfigurement of the neck is present due to thyroid disease or 
enlargement, separately evaluate under DC 7800 (burn scar(s) of the 
head, face, or neck; scar(s) of the head, face, or neck due to other 
causes; or other disfigurement of the head, face, or neck).

DC 7902: Thyroid Enlargement, nontoxic

    VA proposes to change the current title of DC 7902, ``Thyroid 
gland, nontoxic adenoma of,'' to ``Thyroid enlargement, nontoxic.'' In 
the context of thyroid function, ``nontoxic'' means that thyroid 
function is normal.
    Because thyroid function is normal, the disabling effects of 
nontoxic thyroid enlargement are a result of disfigurement or pressure 
on adjacent organs. A person with this condition may experience one or 
both of these effects. However, under the current criteria an 
evaluation may only be assigned for the more disabling effect. 
Therefore, to better reflect the full impact of the condition, VA 
proposes to amend the existing criteria to account for both effects 
occurring simultaneously.
    When the enlarged thyroid gland compresses adjacent organs, it may 
produce symptoms due to pressure on anterior neck structures, including 
the trachea (wheezing, cough), the esophagus (dysphagia), and the 
recurrent laryngeal nerve (hoarseness). The severity of disabilities 
related to pressure on adjacent organs is best evaluated under the 
DC(s) within the appropriate body system. Therefore, VA proposes to 
edit the current note under DC 7902, which would be proposed Note (1), 
to clarify VA's intention to evaluate the symptoms due to pressure on 
adjacent organs under the appropriate diagnostic code within the 
appropriate body system and to delete the current phrase ``if doing so 
would result in a higher evaluation than using this [DC].'' Currently, 
DC 7902 provides a 20 percent evaluation when there is disfigurement of 
the head or neck and a 0 percent evaluation when there is no such 
disfigurement. Disfigurement due to an enlarged thyroid gland is not 
defined in the existing criteria and, therefore, is subject to 
individual interpretation. Objective criteria for evaluating 
disfigurement of the neck already exist under DC 7800 (burn scar(s) of 
the head, face, or neck; scar(s) of the head, face, or neck due to 
other causes; or other disfigurement of the head, face, or neck). 
Because this set of criteria covers all types of disfigurement of the 
neck and provides a wider range of disability compensation, VA proposes 
deletion of the current criteria and addition of proposed Note (2) 
stating that disfigurement of the neck related to nontoxic thyroid 
enlargement should be evaluated under DC 7800.
    The proposed notes read as follows: ``Note (1): Evaluate symptoms 
due to pressure on adjacent organs (such as the trachea, larynx, or 
esophagus) under the appropriate diagnostic code(s) within the 
appropriate body system.'' ``Note (2): If disfigurement of the neck is 
present due to thyroid disease or enlargement, separately evaluate 
under DC 7800 (burn scar(s) of the head, face, or neck; scar(s) of the 
head, face, or neck due to other causes; or other disfigurement of the 
head, face, or neck).''

DC 7903: Hypothyroidism

    Hypothyroidism is currently evaluated at levels of 100, 60, 30, and 
10 percent. Severe hypothyroidism is characterized by myxedema (coma or 
crisis), a life-threatening form of hypothyroidism found predominantly 
in undiagnosed or undertreated individuals that requires inpatient 
hospitalization for stabilization. Medical advances in the diagnosis 
and treatment of hypothyroidism have decreased the incidence of 
myxedema to the point that myxedema coma occurs in only 0.1 percent of 
all cases of hypothyroidism. Erik D Schraga, MD, ``Hypothyroidism and 
Myxedema Coma in Emergency Medicine,'' Medscape Reference (Mar. 29, 
2012), https://emedicine.medscape.com/article/768053-overview. Symptoms 
of myxedema are currently evaluated at 100 and 60 percent. However, 
given the severity of the condition, a 60 percent evaluation is 
insufficient. Therefore, VA proposes a 100 percent evaluation for all 
instances of hypothyroidism with myxedema. VA proposes to add a note to 
provide: ``This evaluation shall continue for six months beyond the 
date that an examining physician has determined crisis stabilization. 
Thereafter, the residual effects of hypothyroidism shall be rated under 
the appropriate diagnostic code(s) within the appropriate body 
system(s) (e.g., eye, digestive, and mental disorders).''
    Medical management of hypothyroidism, in the absence of myxedema, 
results in improvement of laboratory values within a few weeks. 
However, alleviation of other clinical symptoms may take up to six 
months to resolve. See Bijay Vaidya, ``Management of Hypthyroidism,'' 
BMJ 337:a801 (2008). Therefore, VA proposes to evaluate hypothyroidism 
in the absence of myxedema at 30 percent for six months after initial 
diagnosis and would explain this in a note that would also provide 
that, thereafter, the residual effects of hypothyroidism shall be rated 
under the most appropriate diagnostic code(s) within the appropriate 
body

[[Page 39014]]

system(s) (e.g., eye, digestive, and mental disorders).
    VA also proposes to add a note to provide that eye involvement 
associated with hypothyroidism would also be evaluated under Sec.  
4.79. Specifically, the proposed note reads: ``If eye involvement, such 
as exophthalmos, corneal ulcer, blurred vision, or diplopia, is also 
present due to thyroid disease, also separately evaluate under 
appropriate diagnostic code(s) in Sec.  4.79, Schedule of Ratings--Eye 
(such as diplopia (DC 6090) or impairment of central visual acuity (DCs 
6061-6066)).''

DC 7904: Hyperparathyroidism

    Hyperparathyroidism, DC 7904, is currently evaluated at levels of 
100, 60, and 10 percent. Due to increased routine laboratory testing, 
hyperparathyroidism is usually diagnosed before patients develop severe 
disease and often before any signs or symptoms, such as kidney stones, 
gastrointestinal problems or weakness, are present. John I. Lew, 
``Surgical Management of Primary Hyperparathyroidism: State of the 
Art,'' 89 Surgical Clinics of N. Am. 1205-25 (2009); 
``Hyperparathyroidism,'' Mayo Clinic, https://www.mayoclinic.com/health/hyperparathyroidism/DS00396. Therefore, the existing criteria for 
evaluations at the 100 and 60 percent rating are no longer appropriate, 
and VA proposes revision of all the criteria consistent with medical 
advances.
    Individuals diagnosed with hyperparathyroidism, but without 
symptoms (asymptomatic), require annual monitoring of their serum 
calcium levels and creatinine clearance (renal function). Bone density 
monitoring is also required every one to two years. These tests help 
medical professionals monitor the progression of the disease and to 
determine when surgery is necessary. Therefore, VA proposes to evaluate 
asymptomatic hyperparathyroidism at 0 percent.
    Individuals with mild hyperparathyroidism may develop symptoms of 
hypercalcemia before surgery is determined to be necessary. Even after 
surgery, mild symptoms may persist. Therefore, VA proposes a 10 percent 
evaluation for the presence of symptoms, such as fatigue, anorexia, 
nausea, or constipation, despite surgery or in subjects deemed not to 
be candidates for surgery who require continuous medications for 
control.
    Potential complications of hyperparathyroidism include gastric 
ulcers, kidney stones, decrease kidney function, and decreased bone 
mass associated with fragility fractures. Early intervention through 
laboratory monitoring generally prevents these complications. An 
increase in serum calcium, decreases in creatinine clearance, and 
decreases in bone density are used as laboratory indicators for the 
worsening of disease and evaluation for surgical intervention. 
Therefore, VA proposes a 60 percent evaluation for hypercalcemia 
indicated by at least one of the following: Total Ca greater than 12mg/
dL (3-3.5 mmol/L), Ionized Ca greater than 5.6 mg/dL (2-2.5 mmol/L), 
creatinine clearance less than 60 mL/min, bone mineral density T-score 
less than 2.5 (SD below mean) at any site or previous fragility 
fracture). Because these findings indicate that surgical or 
pharmacologic intervention is warranted and such intervention usually 
resolves symptoms, VA proposes that the 60 percent evaluation shall 
continue until such intervention occurs. If surgery is not indicated, 
the 60 percent evaluation would continue for 6 months after 
pharmacological treatment begins. After six months, rating would be 
based on residuals under the appropriate diagnostic code(s) within the 
appropriate body system based on examination.
    Parathyroidectomy is the treatment of choice for symptomatic 
hyperparathyroidism. Therefore, VA proposes a 100 percent evaluation 
for six months after surgical intervention for hyperparathyroidism and 
thereafter, an evaluation based on the residuals of hyperparathyroidism 
or medical treatment under the appropriate diagnostic code(s) within 
the appropriate body system.
    VA proposes to amend the current note under DC 7904 by numbering 
the note as proposed Note (4) and clarifying that the residuals of 
hyperparathyroidism are to be rated under the appropriate DC. The 
current note reads: ``Following surgery or treatment, evaluate as 
digestive, skeletal, renal, or cardiovascular residuals or as endocrine 
dysfunction.'' The proposed Note (4) reads: ``Following surgery or 
other treatment, evaluate chronic residuals, such as nephrolithiasis 
(kidney stones), decreased renal function, fractures, vision problems, 
and cardiovascular complications, under the appropriate diagnostic 
codes.''

DC 7905: Hypoparathyroidism

    Parathyroid hormone controls the balance of calcium in the body. 
When there is not enough of this hormone, the condition is known as 
hypoparathyroidism. The predominant symptoms of hypoparathyroidism is 
neuromuscular irritability, including, but not limited to, paresthesias 
(tingling and numbness involving fingertips, toes, or perioral area), 
hyperirritability, fatigue, anxiety, mood swings and/or personality 
disturbances, seizures, hoarseness (due to laryngospasm), wheezing and 
dyspnea (due to bronchospasm), muscle cramps, and electrolyte 
imbalances (hypomagnesemia, hypokalemia, and alkalosis).
    Currently, evaluations are assigned based on some of these 
symptoms. However, because many of the symptoms of parathyroid hormone 
deficiency are caused by an imbalance of calcium in the body (decreased 
extracellular ionized calcium levels and hypocalcemia), when 
hypoparathyroidism is treated with calcium and vitamin D 
supplementation, the symptoms are generally eliminated. Paul 
Fitzgerald, ``Chapter 26. Endocrine Disorders'' (2014), https://accessmedicine.mhmedical.com/content.aspx?bookid=330&Sectionid=44291028. Therefore, VA proposes new 
evaluation criteria that account for this treatment. Specifically, VA 
proposes a 100 percent evaluation for three months after initial 
diagnosis and, thereafter, to rate residual effects, such as 
nephrolithiasis (kidney stones), cataracts, decreased renal function, 
and congestive heart failure under the appropriate DCs.

New DC 7906: Thyroiditis

    VA proposes to add a new DC for thyroiditis, which is inflammation 
of the thyroid gland. The condition most often results from an 
autoimmune disease (known as Hashimoto's thyroiditis), where the immune 
system attacks the thyroid gland.
    However, regardless of the specific cause, thyroiditis may manifest 
as hyperthyroidism, hypothyroidism, or with no change in thyroid 
function. Because hyperthyroidism and hypothyroidism would be addressed 
in the Rating Schedule as proposed DCs 7900 and 7903, respectively, VA 
proposes a note to clarify that these manifestations be rated under 
those DCs.
    While thyroiditis may also be present in a person with normal 
thyroid function, because thyroiditis increases the likelihood of 
developing hyperthyroidism or hypothyroidism, the thyroid function of 
these individuals must be monitored. This factor is not currently 
accounted for in the Rating Schedule. Therefore, for these individuals, 
VA proposes that a 0 percent evaluation for asymptomatic thyroiditis be 
associated with this DC.

[[Page 39015]]

DC 7907: Cushing's Syndrome

    Cushing's syndrome is the result of prolonged elevation in the 
amount of glucocorticoid in the body. The severity of the signs and 
symptoms is determined by the duration and level of glucocorticoid 
exposure.
    Currently, evaluations for Cushing's syndrome are assigned based in 
part on enlargement of the adrenal gland (which produces these 
hormones) and the pituitary gland (which produces hormones that trigger 
the adrenal gland). However, glandular enlargement is not indicative of 
disease severity. Exogenous glucocorticoid exposure (the intake of 
glucocorticoids), the most common cause of Cushing's syndrome, does not 
involve enlargement of the pituitary or adrenal glands. Therefore, VA 
proposes to delete the requirement for the presence of enlargement of 
the pituitary or adrenal gland as one of the criteria required for 100 
and 60 percent evaluations.
    The muscle weakness associated with Cushing's syndrome is a result 
of proximal muscle wasting and weakness caused by excess glucocorticoid 
hormones. This muscle wasting results in the inability to rise from a 
squatting position without assistance, and, in more severe cases, the 
inability to climb stairs or get up from a deep chair. Lynnette K. 
Nieman, MD, ``Epidemiology and clinical manifestations of Cushing's 
syndrome'' UpToDate (Oct. 22, 2013), https://www.uptodate.com/contents/epidemiology-and-clinical-manifestations-of-cushings-syndrome. To 
clarify the criteria for 100 and 60 percent evaluations, VA proposes to 
replace ``loss of muscle strength'' with the more specific criteria of 
``proximal upper and lower extremity muscle wasting that results in 
inability to rise from squatting position, climb stairs, rise from a 
deep chair without assistance, or raise arms.'' VA also proposes to 
remove ``weakness'' from the list of criteria for a 100 percent 
evaluation because it is already captured with language replacing 
``loss of muscle strength.'' With these proposed modifications, a 100 
percent evaluation would be assigned for Cushing's syndrome if there is 
``active, progressive disease, including areas of osteoporosis, 
hypertension, and proximal upper and lower extremity muscle wasting 
that results in inability to rise from a squatting position, climb 
stairs, rise from a deep chair without assistance, or raise arms.'' 
Similarly, VA proposes a 60 percent evaluation for Cushing's syndrome 
if there is ``[p]roximal upper or lower extremity muscle wasting that 
results in inability to rise from a squatting position, climb stairs, 
rise from a deep chair without assistance, or raise arms.'' VA proposes 
no change to the current 30 percent evaluation criteria.
    The treatment for Cushing's syndrome is determined by the 
glucocorticoid source. Endogenous hypercortisolism (overproduction of 
glucocorticoid hormones by the adrenal gland) is treated by surgical 
removal of the adrenal gland, medical adrenalectomy, surgical resection 
of a pituitary tumor, or radiation therapy of the pituitary gland. 
Exogenous hypercortisolism is treated via gradual reduction of the 
outside source, such as corticosteroid medications. Because early 
medical intervention has decreased the complications associated with 
Cushing's syndrome, VA proposes evaluations for Cushing's syndrome at 
the 100, 60, or 30 percent level for six months after initial 
diagnosis. Because treatment may not completely eliminated 
complications or may itself be associated with complications, after six 
months, VA proposes to rate residuals such as adrenal insufficiency, 
cardiovascular, psychiatric, skin, or skeletal complications under the 
appropriate diagnostic code(s) within the appropriate body system. 
Therefore, VA proposes to amend the note following DC 7907 to reflect 
the above proposed changes.

DC 7908: Acromegaly

    Acromegaly, DC 7908, is a condition in which the pituitary gland 
produces excess growth hormone, usually due to a benign tumor. The 
excessive amount of hormone results in enlargement of various body 
tissues, including bone. Acromegaly is currently evaluated at levels of 
100, 60, and 30 percent. VA proposes no changes in the evaluation 
criteria for the 100 and 60 percent levels. The current 30 percent 
evaluation criteria for acromegaly require that there be enlargement of 
acral parts or overgrowth of long bones, and an enlarged sella turcica 
(the depression at the base of the skull where the pituitary gland is 
located). VA proposes to remove ``enlarged sella turcica'' as one of 
the required criteria. Although acromegaly is generally due to a 
pituitary tumor (which commonly results in enlargement of the sella 
turcica), it occasionally arises from causes that do not produce an 
enlarged sella turcica. Further, enlargement of the sella turcica is 
not an indicator of the severity of the condition. Therefore, it is not 
appropriate to retain ``enlarged sella turcica'' as a required 
criterion, and VA proposes to remove it.

DC 7909: Diabetes Insipidus

    Inadequate secretion of or a resistance to antidiuretic hormone 
(ADH) is the cause of diabetes insipidus (DI). ADH limits the amount of 
water that the kidneys allow to leave the body. A lack of or resistance 
to ADH causes excessive excretion of free water. This disease is 
characterized by polyuria (frequent urination), polydipsia (excessive 
thirst), and nocturia (frequent night time urination). Without 
treatment, dehydration and bladder enlargement commonly result. If 
treated, diabetes insipidus does not cause severe problems or a 
reduction in life expectancy. See Goldman's Cecil Medicine Chapter 232 
(24th ed. 2011). The prognosis for this disease is excellent, because 
it is frequently transient and there are excellent medications with 
different means of administration to treat the condition on a chronic 
basis if this condition becomes permanent. Most individuals, even in 
emergency situations, can replace urine loss with increased fluid 
intake. Therefore, the reliance in the current criteria on the need for 
parenteral (IV) hydration is no longer appropriate, and VA proposes 
deletion of the current criteria.
    In its place, in order to allow the condition to become stabilized 
and to determine if the condition is transient or becoming permanent, 
VA proposes a 30 percent evaluation for three months after the initial 
diagnosis. Once the condition is stabilized, the need for long term 
medication can be assessed. Many patients are able to control their 
condition with oral or trans-nasal medication, while others require 
parenteral treatment (when oral or trans-nasal medications are either 
not tolerable or effective). Therefore, VA proposes a reevaluation of 
diabetes insipidus after the three month period. If DI has subsided, VA 
would rate any residuals under the appropriate diagnostic code(s) 
within the appropriate body system. For those DI cases with persistent 
polyuria or requiring continuous hormonal therapy, VA proposes a 10 
percent rating.

DC 7911: Addison's Disease (Adrenocortical Insufficiency)

    The medical community has shifted from the term ``adrenal cortical 
hypofunction'' to the term ``adrenocortical insufficiency.'' Therefore, 
for clarity and consistency with current medical terminology, VA 
proposes to retitle this DC ``Addison's disease (adrenocortical 
insufficiency).'' VA does not propose changes to the

[[Page 39016]]

rating criteria and notes associated with this DC.

DC 7912: Polyglandular Syndrome (Multiple Endocrine Neoplasia, 
Autoimmune Polyglandular Syndrome)

    ``Pluriglandular syndrome'' refers, not to a single condition, but 
to a group of conditions that impact multiple glands in the body. 
Therefore, a person is likely to be given a more specific diagnosis, 
rather than one with this general term. Therefore, VA proposes to 
include the most common forms of the condition in the title of the DC. 
Also, over time, the medical community has shifted from the term 
``pluriglandular'' to ``polyglandular'' when referring to this 
condition. Therefore, to better reflect the terminology currently 
associated with the condition, VA proposes to update the title of DC 
7912 to ``Polyglandular syndrome (multiple endocrine neoplasia, 
autoimmune polyglandular syndrome).'' The current guidance for 
evaluation is to evaluate according to major manifestations. VA 
proposes to revise the guidance to include some of the common 
manifestations of the syndrome. The proposed guidance reads: ``Evaluate 
according to major manifestations to include, but not limited to, Type 
I diabetes mellitus, hyperthyroidism, hypothyroidism, 
hypoparathyroidism, or Addison's disease.''

DC 7913: Diabetes Mellitus

    Diabetes mellitus is a complex condition that impacts individuals 
in a variety of ways. At this time, VA proposes only one clarifying 
amendment to this DC. VA proposes to clarify that the rating criteria 
for a 20, 40, or 60 percent rating require ``one or more daily 
injection'' of insulin. This clarifying amendment is not a substantive 
change but rather a clarification of VA's interpretation of this DC 
that an injection of insulin is required to achieve a 20, 40, 60, or 
100 percent rating. To ensure that the full range of relevant factors 
is adequately addressed, VA is not proposing to amend the remaining 
rating criteria pertaining to this DC at this time. Rather, VA intends 
to establish a work group to specifically address this condition. Upon 
consideration of the work group's findings, VA will determine whether 
amendments to the remaining existing criteria are necessary and such 
amendments, if any, will be addressed in a future proposal.

DC 7914: Neoplasm, Malignant, Any Specified Part of the Endocrine 
System

    VA proposes no changes at this time.

DC 7915: Neoplasm, Benign, Any Specified Part of the Endocrine System

    VA proposes to retain the existing direction to rate this condition 
based on residuals of endocrine dysfunction, but separate the rating 
direction from the title of DC 7915.

DC 7916: Hyperpituitarism (Prolactin Secreting Pituitary Dysfunction)

    The existing note regarding the evaluation of this condition also 
applies to DCs 7917 and 7918 and is given after DC 7918. Therefore, it 
can be overlooked with regard to the other DCs. Therefore, VA proposes 
to include the same note regarding the evaluation of each condition 
directly under each DC and to amend the current note to reflect the 
proposed change. The conditions would all continue to be evaluated as 
malignant or benign neoplasm, as appropriate, so no substantive change 
is being made.

DC 7917: Hyperaldosteronism (Benign or Malignant)

    See discussion of DC 7916.

DC 7918: Pheochromocytoma (Benign or Malignant)

    See discussion of DC 7916.

DC 7919: C-cell Hyperplasia of the Thyroid

    Currently, this condition is rated in the same way as a malignant 
neoplasm. However, this does not adequately address all potential 
manifestations of this condition. Therefore, VA proposes to replace the 
existing note with one that provides as follows: ``If antineoplastic 
therapy is required, evaluate as a malignant neoplasm under DC 7914. If 
a prophylactic thyroidectomy is performed (based upon genetic testing) 
and antineoplastic therapy is not required, evaluate as hypothyroidism 
under DC 7903.'' These changes are in keeping with current medical 
information about C-cell hyperplasia.

Technical Amendments

    VA also proposes several technical amendments. We would add a 
citation reference to 38 U.S.C. 1155 at the end of Sec.  4.119, and we 
would update Appendix A, B, and C of part 4 to reflect the above noted 
proposed amendments.

Paperwork Reduction Act

    This proposed rule contains no provisions constituting a collection 
of information under the Paperwork Reduction Act of 1995 (44 U.S.C. 
3501-3521).

Regulatory Flexibility Act

    The Secretary hereby certifies that this proposed rule would not 
have a significant economic impact on a substantial number of small 
entities as they are defined in the Regulatory Flexibility Act (5 
U.S.C. 601-612). This proposed rule would directly affect only 
individuals and would not directly affect small entities. 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.

Executive Orders 12866 and 13563

    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 the Executive Order.''
    The economic, interagency, budgetary, legal, and policy 
implications of this regulatory action have been examined, and it has 
been determined to be a significant regulatory action under Executive 
Order 12866 because it is likely to result in a rule that may raise 
novel policy issues arising out of legal mandates, the President's 
priorities, or the principles set forth in the Executive Order. VA's 
impact

[[Page 39017]]

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 Web site at https://www.va.gov/orpm/, by following the link for ``VA Regulations Published From FY 
2004 Through Fiscal Year to Date.''

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 proposed rule would have no such 
effect on State, local, and tribal governments, or on the private 
sector.

    Note (1): An Addisonian ``crisis'' consists of the
     rapid onset of peripheral vascular collapse (with
     acute hypotension and shock), with findings that
     may include: anorexia; nausea; vomiting;
     dehydration; profound weakness; pain in abdomen,
     legs, and back; fever; apathy, and depressed
     mentation with possible progression to coma, renal
     shutdown, and death.
    Note (2): An Addisonian ``episode,'' for VA
     purposes, is a less acute and less severe event
     than an Addisonian crisis and may consist of
     anorexia, nausea, vomiting, diarrhea, dehydration,
     weakness, malaise, orthostatic hypotension, or
     hypoglycemia, but no peripheral vascular collapse.
    Note (3): Tuberculous Addison's disease will be
     evaluated as active or inactive tuberculosis. If
     inactive, these evaluations are not to be combined
     with the graduated ratings of 50 percent or 30
     percent for non-pulmonary tuberculosis specified
     under Sec.   4.88b. Assign the higher rating.
7912 Polyglandular syndrome (multiple endocrine
 neoplasia, autoimmune polyglandular syndrome):
    Evaluate according to major manifestations to
     include, but not limited to, Type I diabetes
     mellitus, hyperthyroidism, hypothyroidism,

     restricted diet, and regulation of activities
     (avoidance of strenuous occupational and
     recreational activities) with episodes of
     ketoacidosis or hypoglycemic reactions requiring at
     least three hospitalizations per year or weekly
     visits to a diabetic care provider, plus either
     progressive loss of weight and strength or
     complications that would be compensable if
     separately evaluated...............................
    Requiring one or more daily injection of insulin,                 60
     restricted diet, and regulation of activities with
     episodes of ketoacidosis or hypoglycemic reactions
     requiring one or two hospitalizations per year or
     twice a month visits to a diabetic care provider,
     plus complications that would not be compensable if
     separately evaluated...............................
    Requiring one or more daily injection of insulin,                 40
     restricted diet, and regulation of activities......
    Requiring one or more daily injection of insulin and              20
     restricted diet, or; oral hypoglycemic agent and
     restricted diet....................................
    Manageable by restricted diet only..................              10

[[Page 39019]]

 
    Note (1): Evaluate compensable complications of
     diabetes separately unless they are part of the
     criteria used to support a 100 percent evaluation.
     Noncompensable complications are considered part of
     the diabetic process under DC 7913.
    Note (2): When diabetes mellitus has been
     conclusively diagnosed, do not request a glucose
     tolerance test solely for rating purposes.
7914 Neoplasm, malignant, any specified part of the                  100
 endocrine system
    Note: A rating of 100 percent shall continue beyond
     the cessation of any surgical, X-ray,
     antineoplastic chemotherapy or other therapeutic
     procedure. Six months after discontinuance of such
     treatment, the appropriate disability rating shall
     be determined by mandatory VA examination. Any
     change in evaluation based upon that or any
     subsequent examination shall be subject to the
     provisions of Sec.   3.105(e) of this chapter. If
     there has been no local recurrence or metastasis,
     rate on residuals.
7915 Neoplasm, benign, any specified part of the
 endocrine system:
    Rate as residuals of endocrine dysfunction.
7916 Hyperpituitarism (prolactin secreting pituitary
 dysfunction):
    Note: Evaluate as malignant or benign neoplasm, as
     appropriate.
7917 Hyperaldosteronism (benign or malignant):
    Note: Evaluate as malignant or benign neoplasm, as
     appropriate.
7918 Pheochromocytoma (benign or malignant):
    Note: Evaluate as malignant or benign neoplasm as
     appropriate.
7919 C-cell hyperplasia of the thyroid:
    If antineoplastic therapy is required, evaluate as a
     malignant neoplasm under DC 7914. If a prophylactic
     thyroidectomy is performed (based upon genetic
     testing) and antineoplastic therapy is not
     required, evaluate as hypothyroidism under DC 7903.
