Vasculitis (DC 6350) is evaluated under 38 CFR § 4.88b, DC 6350 using the applicable body-system rating framework. Because it is rated by analogy to the general schedule, the 3 levels below describe the body-system criteria the VA applies — the percentage assigned to Vasculitis depends on the specific findings (range of motion, frequency, severity, or functional loss) documented at the C&P exam and in the medical record.
