What each rating requires

The VA assigns the highest level your evidence actually supports. Read up the stack until your records stop matching.

For three months after initial diagnosis

Thereafter, evaluate chronic residuals, such as nephrolithiasis (kidney stones), cataracts, decreased renal function, and congestive heart failure under the appropriate diagnostic codes.

Hypoparathyroidism is a condition of the endocrine system. The VA rates it under Diagnostic Code 7905, found in 38 CFR § 4.119.

The VA uses a two-stage approach when rating hypoparathyroidism:

A 100% rating is assigned for three months after initial diagnosis.

Thereafter, the VA evaluates the chronic residuals of the condition under the appropriate diagnostic codes. These residuals may include:

When rating hypoparathyroidism, the VA considers:

The date of initial diagnosis, since the 100% rating applies for the first three months following diagnosis.
The chronic residuals of the condition after that initial period. Rather than rating hypoparathyroidism itself at a set level beyond three months, the VA evaluates any lasting effects — such as kidney stones, cataracts, decreased renal function, or congestive heart failure — under the diagnostic codes that specifically apply to those conditions.

This information is drawn directly from the VA rating schedule under 38 CFR § 4.119, Diagnostic Code 7905, for the endocrine system.

These criteria are a rendering of § 4.119, diagnostic code 7905. The official version is the one that governs your rating.

What next

Knowing the criteria is the first half. Getting your file to show them is the second.

Find your level in the stack
Read each rung against what your medical records already say. The level your records document today is the one the VA can support today.
Name the gap
Look at the rung above yours and write down exactly what it asks for that your file does not show yet — a diagnosis, a measurement, a prescribed brace, a doctor’s opinion linking it to service.
Claim it by code
File under diagnostic code 7905 and attach the evidence for the level you are asking for. Other Endocrine System codes may cover your secondary conditions.
