38 CFR
VA Terminology Definition
Plain English Definition
Title 38 of the Code of Federal Regulations - the rulebook containing all VA regulations including disability rating criteria.
Why This Matters
38 CFR Part 4 contains the VA Schedule for Rating Disabilities (VASRD). Understanding these regulations helps you know exactly what criteria apply to your condition and what evidence matters most.
Example
38 CFR 4.71a contains the rating criteria for musculoskeletal conditions. 38 CFR 4.130 covers mental health conditions. Citing specific regulations in your claim shows you understand what's required.
