Hypothyroidism
Hypothyroidism is an underactive thyroid causing fatigue, weight gain, cold intolerance, and slowed thinking. Since the 2018 endocrine revision, VA rates it 30 percent for six months after diagnosis (100 percent if myxedema is present), then rates the lasting residuals under the body systems they affect.
How the VA rates it
DC 7903 uses a time-limited structure rather than a permanent percentage ladder. Uncomplicated hypothyroidism gets 30 percent for six months after initial diagnosis; afterward, VA rates whatever residuals remain (depression or cognitive effects under mental health, eye involvement under the eye schedule, digestive effects, etc.) under those systems' criteria. The severe form with myxedema rates 100 percent, continuing six months beyond crisis stabilization before residuals are rated. Practically, many veterans whose thyroid is well controlled on levothyroxine end up with low or 0 percent ratings unless they document specific residuals.
Rating criteria by percentage
Rated up to 100%Hypothyroidism manifesting as myxedema: cold intolerance, muscular weakness, cardiovascular involvement (such as hypotension, bradycardia, or pericardial effusion), and mental disturbance (such as dementia, slowed thought, or depression). Continues six months beyond crisis stabilization, then residuals are rated in the affected body systems.
Hypothyroidism without myxedema. Assigned for six months after initial diagnosis; thereafter residuals of the disease or its treatment are rated under the appropriate body systems (e.g., eye, digestive, mental disorders).
Secondary condition strategy
Commonly claimed secondary to this
Conditions veterans often develop from this one — each can be its own rating under 38 CFR 3.310.
- Major Depressive Disorder — Depression and cognitive slowing are recognized effects of hypothyroidism and can be rated as residuals under the mental health schedule or claimed secondary.
Evidence that strengthens this claim
- Because the 30 percent rating expires after six months, the long game is documenting residuals: depression, fatigue, cognitive complaints, eye problems, or GI effects, each rated under its own body system.
- Submit the labs (elevated TSH, low T4) and the date of initial diagnosis - the six-month clock runs from diagnosis.
- If you have myxedema-level disease, hospital records showing cardiovascular involvement and mental disturbance support the 100 percent level.
- File within a year of diagnosis when possible so the six-month 30 percent window is actually compensated.
