VA disability claims glossary

Diagnostic code

A diagnostic code is the numeric code VA assigns to a rated condition under 38 CFR Part 4 schedules.

Published 2026-04-02

38 CFR DBQ

Why codes matter

Codes control which rating criteria apply. Similar symptoms with different codes can produce different percentages.

Pyramiding rules

Some conditions cannot be rated separately if they are manifestations of the same disability under pyramiding rules.

Ask questions

If a code looks wrong, discuss with a VSO.
