# C-Cell Hyperplasia of the Thyroid (VA Diagnostic Code 7919)

## Understanding This Condition

C-cell hyperplasia of the thyroid is an endocrine system condition rated by the VA under **Diagnostic Code 7919**, found in the disability rating schedule at **§ 4.119** (Endocrine System).

Because C-cell hyperplasia of the thyroid does not have its own standalone percentage schedule, the VA evaluates it by looking at your specific circumstances and applying the criteria used for a related condition.

## How the VA Rates This Condition

Diagnostic Code 7919 does not use a fixed ladder of rating percentages of its own. Instead, the rating depends on how the condition is being treated:

- **If antineoplastic therapy is required:** The condition is evaluated as a **malignant neoplasm under Diagnostic Code 7914**.
- **If a prophylactic thyroidectomy is performed (based on genetic testing) and antineoplastic therapy is not required:** The condition is evaluated as **hypothyroidism under Diagnostic Code 7903**.

## What the VA Looks For

When rating C-cell hyperplasia of the thyroid, the VA considers:

- **Whether antineoplastic therapy is required.** If so, the evaluation is directed to the criteria for a malignant neoplasm (Diagnostic Code 7914).
- **Whether a prophylactic thyroidectomy was performed based on genetic testing, without the need for antineoplastic therapy.** If so, the evaluation is directed to the criteria for hypothyroidism (Diagnostic Code 7903).

Because the applicable rating criteria are drawn from these referenced diagnostic codes, the treatment path documented in your medical records plays a central role in how this condition is evaluated.
