The VA rating for hypothyroidism is 30% for six months after diagnosis, or 100% for six months if the case involves myxedema. Both ratings are temporary. When the six months end, the VA re-evaluates you and rates each lingering symptom separately under the body system it affects, and that is usually where the real compensation is decided.1eCFR. 38 CFR 4.119 – Schedule of Ratings, Endocrine System
The Two Ratings Under Diagnostic Code 7903
The current schedule, in effect since December 10, 2017, has only two levels.2Federal Register. Schedule for Rating Disabilities – The Endocrine System Older references to a four-tier scale with 10%, 30%, 60%, and 100% ratings no longer apply.
A 100% rating goes to hypothyroidism with myxedema, a rare, life-threatening complication of severely undertreated or undiagnosed disease. The VA looks for cold intolerance, muscular weakness, cardiovascular problems such as low blood pressure or slow heart rate, and mental disturbance like depression or slowed thinking. The 100% rating runs for six months after a physician determines the crisis has stabilized.1eCFR. 38 CFR 4.119 – Schedule of Ratings, Endocrine System
Every other case of hypothyroidism gets a 30% rating for six months after the initial diagnosis. As of 2026, a 30% rating pays $552.47 per month for a veteran with no dependents.3Veterans Affairs. Current Veterans Disability Compensation Rates
The reason the schedule is built this way: medication usually normalizes thyroid levels within weeks, but symptoms like fatigue and weight changes can linger for months.4Federal Register. Schedule for Rating Disabilities – The Endocrine System The temporary rating covers that adjustment window.
What Happens After Six Months
When the temporary rating expires, the VA does not simply drop your compensation. It re-evaluates the condition and rates any ongoing symptoms, called residuals, under the diagnostic codes for the body systems those symptoms affect.1eCFR. 38 CFR 4.119 – Schedule of Ratings, Endocrine System Hypothyroidism can touch several body systems at once, so several residuals may each carry their own rating.
Common residuals include depression or cognitive sluggishness rated under the mental disorders schedule, cardiovascular symptoms like slow heart rate, digestive symptoms such as constipation, and eye involvement including blurred or double vision. In one 2023 Board of Veterans’ Appeals case, a veteran’s hypothyroidism was initially rated at 30%, but after re-evaluation her depressive symptoms alone warranted a 70% rating under the mental disorders formula.5Board of Veterans’ Appeals. Decision in Docket No. 220718-261349 Residuals can end up producing far more compensation than the original 30%.
If the VA thinks your condition is likely to improve, expect a re-evaluation exam two to five years out. It can also schedule one sooner if new medical evidence suggests improvement. You have 60 days to submit evidence showing your condition has not improved. Missing a scheduled exam without good cause can reduce or stop your benefits.
The Anti-Pyramiding Rule
The VA cannot rate the same symptom under two different diagnostic codes.6eCFR. 38 CFR Part 4 – Schedule for Rating Disabilities If fatigue is already counted in your mental health rating, it cannot also be counted separately elsewhere. The rule prevents double compensation, but it also means the diagnostic code you assign each symptom to matters. Veterans often benefit from working with an accredited claims agent or attorney during the residual stage for this reason.
Proving Hypothyroidism Is Connected to Service
Before any rating applies, the condition has to be service-connected. There are three pathways.
Direct Service Connection
A direct claim needs three elements: a current hypothyroidism diagnosis confirmed by lab work and a licensed provider, evidence of something in service that could have caused it, and a medical opinion linking the two, usually a nexus letter.7Veterans Affairs. Eligibility for VA Disability Benefits
The nexus letter has to say the hypothyroidism was “at least as likely as not” caused or worsened by an in-service event. That phrase is the VA’s legal standard, meaning a 50% or greater probability. A letter calling the connection “possible” will not clear the bar. The opinion should come from someone qualified through education, training, or experience, and it should reference your service and medical records specifically.
Presumptive Service Connection
Hypothyroidism is on the VA’s presumptive list for Agent Orange exposure.8Veterans Affairs. Agent Orange Presumptive Conditions If you served in Vietnam, Thailand, or another qualifying location during the covered period and have a current diagnosis, you do not need a nexus letter or proof of a specific in-service event.7Veterans Affairs. Eligibility for VA Disability Benefits
One boundary worth flagging: the PACT Act of 2022 did not add hypothyroidism to its presumptive list. Its presumptive conditions are primarily respiratory illnesses and certain cancers.9Veterans Affairs. Exposure to Burn Pits and Other Specific Environmental Hazards Burn pit veterans can still claim hypothyroidism through direct or secondary service connection, but there is no presumptive shortcut.
Secondary Service Connection
If your hypothyroidism was caused or worsened by an already service-connected condition, you can claim it as secondary. The VA grants secondary service connection when a disability is “proximately due to or the result of” an existing service-connected condition.10eCFR. 38 CFR 3.310 – Disabilities That Are Proximately Due to, or Aggravated by, Service-Connected Disease or Injury
Two scenarios come up repeatedly in Board decisions. Lithium prescribed for PTSD and mood disorders is a documented cause of thyroid dysfunction; in a 2022 case, the Board granted service connection after a physician confirmed that long-term lithium use for service-connected PTSD caused the veteran’s hypothyroidism.11Board of Veterans’ Appeals. Entitlement to Service Connection for Hypothyroidism Secondary to PTSD Radiation exposure during service is a recognized cause of thyroid damage that can appear years later.12Board of Veterans’ Appeals. Order Granting Service Connection for Thyroid Nodules and Hypothyroidism Due to Radiation Exposure
For aggravation claims, where hypothyroidism existed before the service-connected condition but got worse because of it, the VA needs a baseline severity established by medical evidence. The rating covers only the increase beyond that baseline.10eCFR. 38 CFR 3.310 – Disabilities That Are Proximately Due to, or Aggravated by, Service-Connected Disease or Injury
Filing the Claim and the C&P Exam
You file using VA Form 21-526EZ on VA.gov.13Veterans Affairs. File for Disability Compensation With VA Form 21-526EZ Starting the online application counts as an intent to file, which preserves your effective date while you gather evidence. A VA regional office at 800-827-1000 or a Veterans Service Organization can help.
Gather recent lab results showing TSH and free T4 levels, treating physician records documenting diagnosis and treatment, and, for direct or secondary claims, a nexus letter.14U.S. Department of Veterans Affairs. Hypothyroidism – Whole Health Library Do not wait for perfect records. You can add evidence after filing, and delay costs back pay.
After you file, the VA will usually schedule a Compensation and Pension exam. This is not treatment. The examiner reviews your claims file, examines you, and fills out a Disability Benefits Questionnaire for thyroid and parathyroid conditions.15Department of Veterans Affairs. Thyroid and Parathyroid Disability Benefits Questionnaire The examiner does not set your rating, but their findings drive it.
Go in prepared to describe every symptom in specific terms. How often the fatigue hits, how it affects your ability to work, whether cold intolerance limits activities, whether you have memory lapses or trouble concentrating. Vague answers produce vague findings. If you have symptoms the examiner does not ask about — weight changes, constipation, joint pain, depressive episodes — raise them yourself. Those details feed the residual ratings that follow the initial six months.
When Residuals Prevent You From Working
If your hypothyroidism residuals combined with other service-connected conditions make it impossible to hold a job, you may qualify for Total Disability based on Individual Unemployability, or TDIU, which pays at the 100% rate even when your combined schedular rating is lower.
Schedular TDIU requires either one service-connected disability rated at 60% or more, or a combined rating of 70% with at least one disability rated at 40% or more.16eCFR. 38 CFR 4.16 – Total Disability Ratings for Compensation Disabilities affecting the same body system count as a single disability for those thresholds. Because hypothyroidism residuals can span endocrine, cardiovascular, and mental health systems, several individually modest ratings may combine to reach TDIU.
Even below those thresholds, the VA can refer a case for extraschedular consideration when the evidence shows the veteran cannot maintain substantially gainful employment because of service-connected conditions.16eCFR. 38 CFR 4.16 – Total Disability Ratings for Compensation The VA weighs education, work history, and training, but not age or non-service-connected health problems.
If You Disagree With Your Rating
If the VA underrated your condition or denied the claim, you have three review options, and the deadline for two of them is one year from the decision date.
- A supplemental claim adds new and relevant evidence. You can file at any time, but filing within one year preserves your original effective date.
- A higher-level review has a more senior reviewer look at the same evidence for errors. No new evidence is allowed. One-year deadline.
- A Board appeal sends the case to the Board of Veterans’ Appeals, with the option of direct review, new evidence, or a hearing. One-year deadline.
Missing the one-year deadline for a higher-level review or Board appeal eliminates those options, and a supplemental claim with new evidence becomes the only route.17Veterans Affairs. Choosing a Decision Review Option For hypothyroidism specifically, the most common winning basis is the residual ratings after the temporary period. If the VA rated your residuals too low or missed an affected body system, a supplemental claim with updated medical evidence documenting those symptoms is usually the strongest path.18Veterans Affairs.
