# DC 7900 - Hyperthyroidism, including, but not limited to, Graves' disease

Rated under § 4.119. Body system: Endocrine System.

## Rating criteria

| Rating | Criteria |
| --- | --- |
| 30% | For six months after initial diagnosis |
| 0% | Thereafter, rate residuals of disease or complications of medical treatment within the appropriate diagnostic code(s) within the appropriate body system. |

## Notes

- Note (1): If hyperthyroid cardiovascular or cardiac disease is present, separately evaluate under DC 7008 (hyperthyroid heart disease).
- Note (2): 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 § 4.79.

# Hyperthyroidism (Including Graves' Disease) — VA Diagnostic Code 7900

*Endocrine System · 38 CFR § 4.119 · Diagnostic Code 7900*

## Understanding the Condition

Hyperthyroidism is a condition of the endocrine system in which the thyroid gland is overactive. Graves' disease is one form of hyperthyroidism, though this diagnostic code covers hyperthyroidism generally — "including, but not limited to, Graves' disease."

The VA evaluates this condition under Diagnostic Code 7900, found in the endocrine system section of the rating schedule (§ 4.119).

## Available Rating Levels

The VA uses the following rating structure for hyperthyroidism:

| Rating | What It Reflects |
|--------|------------------|
| **30%** | For six months after initial diagnosis |
| **0%** | Thereafter, residuals of the disease or complications of medical treatment are rated within the appropriate diagnostic code(s) in the appropriate body system |

In plain terms: an initial 30% rating applies for the first six months following diagnosis. After that six-month period, the condition is rated at 0% under this code, and any remaining effects — such as residuals of the disease or complications from medical treatment — are evaluated under whichever diagnostic codes and body systems best fit those effects.

## What the VA Looks For

When rating hyperthyroidism, the VA considers the following:

- **Timing since diagnosis.** The 30% rating is tied specifically to the six-month period after initial diagnosis. After that, the evaluation shifts to a 0% rating under this code, with attention to any residuals or treatment complications rated elsewhere.

- **Heart involvement (Note 1).** If hyperthyroid cardiovascular or cardiac disease is present, it is evaluated separately under Diagnostic Code 7008 (hyperthyroid heart disease).

- **Eye involvement (Note 2).** Eye involvement that occurs as a manifestation of Graves' disease is evaluated separately — as diplopia (DC 6090), as impairment of central visual acuity (DCs 6061–6066), or under the most appropriate diagnostic codes in § 4.79.

Because residuals and complications can be rated under other body systems, the full picture of how hyperthyroidism affects you may be captured across more than one diagnostic code.
