Herpes Simplex (Chronic) is rated by the U.S. Department of Veterans Affairs under DC 7820 of 38 CFR § 4.118, DC 7820 across 3 severity tiers (40%+ -- Severe limitation or ankylosis / 20% -- Moderate limitation / 10% -- Mild limitation or painful motion). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303.
Chronic viral infection caused by herpes simplex virus type 1 (oral) or type 2 (genital). Causes recurrent painful outbreaks of blisters/sores. Latent virus reactivates during stress, illness, or immunosuppression.
Herpes Simplex (Chronic) (DC 7820) is evaluated under 38 CFR § 4.118, DC 7820 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 Herpes Simplex (Chronic) depends on the specific findings (range of motion, frequency, severity, or functional loss) documented at the C&P exam and in the medical record.
