VA rating criteria, organized so you can actually use them.
Every VA disability percentage traces to a written criterion in the rating schedule, 38 CFR Part 4. This hub organizes the Desk's coverage of that schedule: plain language guides by body system, the diagnostic code index, the combined ratings math, and the primary sources behind each number.
What this hub covers
The criteria
Start with the guide for the body system, then verify against the diagnostic code and the condition page.
The exact rating math for the most claimed conditions: diagnostic code, percentage criteria, and the details that change the evaluation.
Look up any diagnostic code and jump to the criteria that govern it.
Condition by condition pages with criteria summaries, evidence notes, and research starting points.
Which conditions are commonly claimed as secondary to which, with the medical literature that has studied each link.
What each criterion actually asks for, organized by condition.
The packet, the narrative, and the codesheet behind it, section by section.
The math
Ratings do not simply add. These tools compute the schedule's actual arithmetic and show their work.
The 38 CFR 4.25 combined ratings table, computed transparently step by step.
Current pay rates for any rating and dependent combination.
The full compensation tables, kept current with each COLA.
What combination of ratings reaches a target combined percentage.

The controlling text is always the regulation itself: 38 CFR Part 4 on eCFR. Desk guides state which sections they rely on and when they were last reviewed. See how we review for the process.
