Overview of VA Endocrine Condition Ratings

Endocrine conditions involve disorders of the hormone-producing glands that regulate many of the body’s functions. Military service can lead to endocrine disorders through environmental exposures, traumatic injuries, stress, or as secondary effects of other service-connected conditions. This section explains how the VA rates endocrine conditions and provides detailed guidance for the most common conditions.

General Rating Principles for Endocrine Conditions

The VA rates endocrine conditions based on several factors:

• Required treatments: Medications, insulin, dietary restrictions, or other therapies needed
• Frequency of medical visits: How often you need to see healthcare providers for your condition
• Complications: Secondary conditions that develop as a result of the endocrine disorder
• Impact on daily activities: How the condition affects your ability to work and perform daily tasks
• Hospitalizations: Frequency and duration of hospitalizations required for the condition

Diabetes Mellitus

Diabetes mellitus is a chronic condition that affects how your body processes blood sugar (glucose). There are two main types: type 1, which is an autoimmune condition where the body doesn’t produce insulin, and type 2, which is characterized by insulin resistance. Type 2 diabetes is much more common and is the type presumptively associated with Agent Orange exposure.

Establishing Service Connection for Diabetes

To establish service connection for diabetes, you need:

1. Diagnosis of diabetes mellitus by a qualified medical professional
2. Evidence of service in a location that qualifies for presumptive service connection (for Agent Orange exposure), OR evidence of onset during service or within one year of discharge, OR evidence of a service-connected condition that caused or aggravated your diabetes
3. Medical nexus linking your diabetes to service or to another service-connected condition (not required for presumptive service connection)

VA Rating Criteria for Diabetes Mellitus

Diabetes mellitus is rated under Diagnostic Code 7913 based on the required treatment and complications:

Rating	Criteria
100%	Requiring more than one daily injection of insulin, 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
60%	Requiring insulin, 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
40%	Requiring insulin, restricted diet, and regulation of activities
20%	Requiring insulin and restricted diet, or; oral hypoglycemic agent and restricted diet
10%	Manageable by restricted diet only

Evidence Needed for Diabetes Claims

To support your diabetes claim, gather the following evidence:

Medical Evidence

• Diagnosis of diabetes mellitus from a qualified medical professional
• Medical records showing required treatments (insulin, oral medications, dietary restrictions)
• Documentation of any regulation of activities prescribed by a doctor
• Records of hospitalizations for ketoacidosis or hypoglycemic reactions
• Documentation of frequency of visits to diabetic care providers
• Medical evidence of any complications related to diabetes
• Lab results showing blood glucose levels and A1C readings

Service Records

• Evidence of service in locations qualifying for presumptive service connection (Vietnam, Korean DMZ, etc.)
• Service treatment records showing onset or symptoms of diabetes during service
• Medical records showing diagnosis within one year of discharge (for presumptive service connection based on chronic disease)

Lay Evidence

• Personal statements describing how diabetes affects your daily life and ability to work
• Statements from family members or friends who have observed the impact of your diabetes
• Log of hypoglycemic episodes or other symptoms
• Description of how diabetes limits your activities

Tips for Successful Diabetes Claims

• Focus on “Regulation of Activities”: For a 40% rating, you need evidence that a doctor has prescribed avoidance of strenuous activities specifically to control blood sugar. General exercise recommendations are not sufficient.
• Document All Complications: Ensure that all complications of diabetes are thoroughly documented and file separate claims for each complication.
• Get Proper Medical Documentation: Have your doctor specifically document all treatments required for your diabetes, including exact insulin dosages and frequency.
• Keep a Symptom Log: Maintain a detailed log of hypoglycemic episodes, ketoacidosis, and other symptoms to support your claim.
• Address Secondary Service Connection: If you believe your diabetes is secondary to another service-connected condition, obtain a medical opinion explaining this relationship.

Diabetes Insipidus

Overview of Diabetes Insipidus

Diabetes insipidus (DI) is a rare condition that causes excessive thirst and urination. Despite sharing part of its name with diabetes mellitus, it’s a completely different disorder. Diabetes insipidus occurs when your body can’t properly regulate water balance due to problems with antidiuretic hormone (ADH), also known as vasopressin.

There are two main types of diabetes insipidus:

• Central diabetes insipidus: Caused by damage to the pituitary gland or hypothalamus, resulting in insufficient production of ADH
• Nephrogenic diabetes insipidus: Caused by kidney resistance to ADH, often due to medications or kidney disease

Symptoms of diabetes insipidus include:

• Extreme thirst
• Excessive urination (often 3-20 liters per day)
• Dehydration
• Electrolyte imbalances
• Fatigue
• Disrupted sleep due to frequent urination

Military service can lead to diabetes insipidus through:

• Traumatic brain injury affecting the pituitary gland or hypothalamus
• Surgical procedures near the pituitary gland
• Certain medications
• Infections affecting the brain

Service Connection for Diabetes Insipidus

To establish service connection for diabetes insipidus, you generally need:

1. Current diagnosis of diabetes insipidus
2. Evidence of an in-service event that could have caused your diabetes insipidus (such as TBI, surgery, or certain medications)
3. Medical nexus linking your current diabetes insipidus to the in-service event

Diabetes insipidus can also be secondary to other service-connected conditions, particularly traumatic brain injury or pituitary tumors.

VA Disability Ratings for Diabetes Insipidus

Diabetes insipidus is rated under Diagnostic Code 7909 based on the severity of symptoms and required treatment:

Rating	Criteria
100%	Polyuria with near-continuous thirst, and more than two documented episodes of dehydration requiring parenteral hydration in the past year
60%	Polyuria with near-continuous thirst, and one or two documented episodes of dehydration requiring parenteral hydration in the past year
40%	Polyuria with near-continuous thirst, and one or more episodes of dehydration in the past year not requiring parenteral hydration
20%	Polyuria with near-continuous thirst

Evidence Needed for Diabetes Insipidus Claims

To support your diabetes insipidus claim, gather the following evidence:

Medical Evidence

• Diagnosis of diabetes insipidus from a qualified medical professional
• Results of water deprivation tests or other diagnostic tests
• Documentation of urine volume and frequency

• Documentation of prescribed medications (desmopressin/DDAVP or others)
• Medical opinions linking your diabetes insipidus to military service

Service Records

• Service treatment records showing head injuries, pituitary surgery, or other relevant conditions
• Documentation of medications taken during service that could cause diabetes insipidus
• Medical records showing symptoms of excessive thirst or urination during service

Lay Evidence

• Personal statements describing how diabetes insipidus affects your daily life
• Log of daily fluid intake and urination frequency/volume
• Description of how symptoms disrupt sleep, work, and social activities
• Statements from family members or friends who have observed your symptoms

Hypothyroidism

Overview of Hypothyroidism

Hypothyroidism is a condition in which the thyroid gland doesn’t produce enough thyroid hormone. The thyroid is a butterfly-shaped gland in the neck that produces hormones that regulate metabolism, energy production, and many other bodily functions.

Symptoms of hypothyroidism can include:

• Fatigue and weakness
• Increased sensitivity to cold
• Constipation
• Dry skin and hair
• Unexplained weight gain
• Puffy face
• Hoarseness
• Muscle aches and stiffness
• Joint pain and stiffness
• Depression
• Impaired memory and concentration
• Slowed heart rate

Military service can lead to hypothyroidism through various factors:

• Exposure to radiation
• Exposure to certain chemicals
• Autoimmune reactions triggered by stress or environmental factors
• Iodine deficiency during deployment
• Neck injuries

Service Connection for Hypothyroidism

To establish service connection for hypothyroidism, you generally need:

1. Current diagnosis of hypothyroidism
2. Evidence of an in-service event that could have caused your hypothyroidism
3. Medical nexus linking your current hypothyroidism to the in-service event

VA Disability Ratings for Hypothyroidism

Hypothyroidism is rated under Diagnostic Code 7903 based on the severity of symptoms and required treatment:

Rating	Criteria
100%	Cold intolerance, muscular weakness, cardiovascular involvement, mental disturbance (dementia, slowing of thought, depression), bradycardia (less than 60 beats per minute), and sleepiness
60%	Muscular weakness, mental disturbance, and weight gain
30%	Fatigability, constipation, and mental sluggishness
10%	Fatigability, or; continuous medication required for control

Evidence Needed for Hypothyroidism Claims

To support your hypothyroidism claim, gather the following evidence:

Medical Evidence

Tips for Successful Hypothyroidism Claims

• Document All Symptoms: Make sure your medical records clearly document all symptoms related to the VA rating criteria, especially fatigability, constipation, mental sluggishness, muscular weakness, and mental disturbance.
• Get Proper Testing: Ensure you have comprehensive thyroid function tests (TSH, T3, T4) to confirm your diagnosis.
• Address Medication Effects: Even if medication controls some symptoms, document any symptoms that persist despite treatment.
• Consider Secondary Conditions: Hypothyroidism can cause or aggravate other conditions, such as depression, cardiovascular problems, and cognitive issues. Consider filing secondary claims for these conditions.
• Highlight Presumptive Connection: If you served in Vietnam or participated in radiation-risk activities, emphasize this in your claim for presumptive service connection.

Hyperthyroidism

Overview of Hyperthyroidism

Hyperthyroidism is a condition in which the thyroid gland produces too much thyroid hormone. This causes many bodily functions to speed up, resulting in a variety of symptoms. The most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder.

Symptoms of hyperthyroidism can include:

• Unintentional weight loss
• Rapid heartbeat (tachycardia)
• Irregular heartbeat (arrhythmia)
• Palpitations
• Increased appetite
• Nervousness, anxiety, and irritability
• Tremor in hands and fingers
• Sweating
• Changes in menstrual patterns
• Increased sensitivity to heat
• More frequent bowel movements
• Fatigue and muscle weakness
• Sleep difficulties
• Enlarged thyroid gland (goiter)

Military service can lead to hyperthyroidism through various factors:

• Stress, which can trigger autoimmune disorders like Graves’ disease
• Exposure to certain chemicals or toxins
• Iodine excess from certain medications or contrast agents
• Radiation exposure

Service Connection for Hyperthyroidism

To establish service connection for hyperthyroidism, you generally need:

1. Current diagnosis of hyperthyroidism or a related condition (such as Graves’ disease)
2. Evidence of an in-service event that could have caused your hyperthyroidism
3. Medical nexus linking your current hyperthyroidism to the in-service event

Hyperthyroidism can also be service-connected if it manifests to a compensable degree within one year of discharge, as it is considered a chronic disease under 38 CFR § 3.309(a).

VA Disability Ratings for Hyperthyroidism

Hyperthyroidism (toxic goiter) is rated under Diagnostic Code 7900 based on the severity of symptoms and required treatment:

Rating	Criteria
100%	Thyroid enlargement, tachycardia (more than 100 beats per minute), eye involvement, muscular weakness, loss of weight, and sympathetic nervous system, cardiovascular, or gastrointestinal symptoms
60%	Thyroid enlargement, tachycardia, eye involvement, and either tremor or increased pulse pressure of more than 40mm Hg
30%	Tachycardia, tremor, and increased pulse pressure or blood pressure
10%	Tachycardia, which may be intermittent, and tremor, or; continuous medication required for control

Evidence Needed for Hyperthyroidism Claims

To support your hyperthyroidism claim, gather the following evidence:

Medical Evidence

• Diagnosis of hyperthyroidism from a qualified medical professional
• Thyroid function test results showing elevated thyroid hormone levels
• Documentation of any treatments (medications, radioactive iodine, surgery)

Adrenal Gland Disorders

Overview of Adrenal Gland Disorders

The adrenal glands are small, triangular-shaped glands located on top of each kidney. They produce hormones that help regulate metabolism, immune system, blood pressure, response to stress, and other essential functions. Disorders of the adrenal glands can involve either excessive or insufficient production of these hormones.

Common adrenal gland disorders include:

• Addison’s disease (adrenal insufficiency): Insufficient production of cortisol and sometimes aldosterone
• Cushing’s syndrome: Excessive production of cortisol
• Adrenal tumors: Can cause either excessive or insufficient hormone production
• Congenital adrenal hyperplasia: Genetic disorder affecting cortisol production
• Adrenal crisis: Life-threatening condition resulting from insufficient cortisol

Symptoms vary depending on the specific disorder but can include:

• Fatigue and weakness
• Weight changes (loss or gain)
• Changes in blood pressure
• Mood changes, irritability, or depression
• Changes in skin (thinning, bruising easily, darkening)
• Muscle and joint pain
• Salt cravings (in Addison’s disease)
• Nausea, vomiting, or abdominal pain
• Dizziness or fainting

Military service can lead to adrenal gland disorders through various factors:

• Traumatic injuries to the adrenal glands
• Stress, which can affect adrenal function
• Autoimmune reactions triggered by environmental factors
• Infections that affect the adrenal glands
• Sudden withdrawal from steroid medications

Service Connection for Adrenal Gland Disorders

To establish service connection for adrenal gland disorders, you generally need:

1. Current diagnosis of an adrenal gland disorder
2. Evidence of an in-service event that could have caused your adrenal gland disorder
3. Medical nexus linking your current adrenal gland disorder to the in-service event

Adrenal gland disorders can also be secondary to other service-connected conditions or treatments, such as:

• Infections that damage the adrenal glands
• Autoimmune disorders that affect the adrenal glands
• Traumatic brain injury affecting the pituitary gland (which controls the adrenal glands)
• Long-term use of steroid medications for service-connected conditions

VA Disability Ratings for Adrenal Gland Disorders

Adrenal gland disorders are rated under several diagnostic codes, depending on the specific condition:

Diagnostic Code 7911: Addison’s Disease (Adrenal Cortical Hypofunction)

Rating	Criteria
60%	Four or more crises during the past year
40%	Three crises during the past year, or; five or more episodes during the past year
20%	One or two crises during the past year, or; two to four episodes during the past year, or; weakness and fatigability, or; corticosteroid therapy required for control

Note: An Addisonian “crisis” consists of the rapid onset of peripheral vascular collapse (with 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.

An Addisonian “episode,” for VA purposes, means a less acute and less severe event than a crisis and may consist of anorexia, nausea, vomiting, diarrhea, dehydration, weakness, malaise, orthostatic hypotension, or hypoglycemia, but no peripheral vascular collapse.

Diagnostic Code 7907: Cushing’s Syndrome

Rating	Criteria
100%	As active, progressive disease including loss of muscle strength, areas of osteoporosis, hypertension, weakness, and enlargement of pituitary or adrenal gland
60%	With any of the following: striae, obesity, moon face, glucose intolerance, hypertension, osteoporosis, or psychiatric disturbances
30%	With centripetal obesity, glucose intolerance, hypertension, or weakness
10%	Continuous medication required for control

Evidence Needed for Adrenal Gland Disorder Claims

To support your adrenal gland disorder claim, gather the following evidence:

Medical Evidence

• Diagnosis of adrenal gland disorder from a qualified medical professional
• Hormone level test results (cortisol, ACTH, aldosterone, etc.)
• Documentation of prescribed medications (corticosteroids, etc.)
• Records of any hospitalizations for adrenal crises or episodes
• Documentation of symptoms and their severity
• Medical opinions linking your adrenal disorder to military service

Service Records

• Service treatment records showing adrenal issues or related symptoms
• Documentation of traumatic injuries or infections
• Records of steroid medication use during service
• Evidence of stressful events or high-stress deployments

Lay Evidence

• Personal statements describing how your adrenal disorder affects your daily life
• Log of crises or episodes, including frequency and severity
• Description of symptoms and their impact on activities
• Statements from family members or friends who have observed your symptoms

Other Endocrine Conditions

Pituitary Disorders

The pituitary gland, often called the “master gland,” controls many other hormone-producing glands. Pituitary disorders can include tumors, hormone deficiencies, or overproduction of hormones. These conditions can be rated under various diagnostic codes depending on the specific disorder and its effects on other glands.

Parathyroid Disorders

The parathyroid glands regulate calcium levels in the blood. Disorders can cause either too much (hyperparathyroidism) or too little (hypoparathyroidism) parathyroid hormone production, leading to calcium imbalances that can affect bones, kidneys, and other organs.

Pancreatic Disorders

Beyond diabetes, the pancreas can be affected by other conditions such as pancreatitis, pancreatic insufficiency, or pancreatic tumors. These conditions may be rated separately or considered as part of diabetes complications depending on the specific circumstances.

If you have an endocrine condition not specifically covered in this guide, consult with a Veterans Service Officer (VSO) or accredited representative for assistance with your claim.
