# Toxic Thyroid Enlargement (VA Diagnostic Code 7901)

**Endocrine System · 38 CFR § 4.119**

## Understanding This Condition

Toxic thyroid enlargement refers to an enlarged thyroid gland accompanied by excess thyroid hormone activity (a "toxic" state). Because this condition overlaps closely with hyperthyroidism and can also affect the appearance of the neck, the VA does not rate it with a standalone set of percentage levels. Instead, it directs evaluators to rate the underlying symptoms and any related effects under other, more specific diagnostic codes.

## How the VA Rates It

VA Diagnostic Code 7901 does not include its own rating percentages. Rather than assigning a fixed rating under this code, the VA evaluates the condition through the related diagnostic codes that most accurately capture your symptoms:

- **Symptoms of hyperthyroidism** are evaluated under **Diagnostic Code 7900** (hyperthyroidism, including, but not limited to, Graves' disease).
- **Disfigurement of the neck** caused by the thyroid disease or enlargement is evaluated **separately** under **Diagnostic Code 7800** (burn scars of the head, face, or neck; scars of the head, face, or neck due to other causes; or other disfigurement of the head, face, or neck).

## What the VA Looks For

When reviewing a claim involving toxic thyroid enlargement, the VA considers:

- **Hyperthyroid symptoms** — these are directed to be evaluated under Diagnostic Code 7900, the criteria used for hyperthyroidism and related conditions such as Graves' disease.
- **Neck disfigurement** — if the thyroid disease or enlargement causes disfigurement of the neck, the VA is instructed to evaluate that disfigurement separately under Diagnostic Code 7800.

Because the rating is built from these related codes, the specific symptoms you experience and any resulting effects on the neck's appearance both play a role in how your condition is assessed.
