✓ VERIFIED AGAINST 38 C.F.R.§ 4.124a (Neurological conditions and convulsive disorders) · reviewed 2026-05-15 · ClaimRecon Editorial Team
Encephalitis (Epidemic) is rated by the U.S. Department of Veterans Affairs under DC 8000 of 38 CFR § 4.124a, DC 8000 across 2 severity tiers (10% / 100%). 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.
OVERVIEW
Inflammation of the brain tissue causing cognitive impairment, seizures, and neurological deficits.
RATING CRITERIA (2 LEVELS)
10%
Residuals after acute febrile phase resolution, minimum rating per § 4.124a DC 8000. Rate residuals (cognitive impairment, seizures, focal motor deficits, behavioral changes, neuroendocrine dysfunction) separately under their applicable DCs and combine under § 4.25.
100%
Active febrile disease — 100% per § 4.124a DC 8000. Applies to viral encephalitis (HSV, arboviral — West Nile / Eastern Equine / Japanese / La Crosse, enteroviral, varicella-zoster), autoimmune encephalitis (anti-NMDA receptor, anti-LGI1, anti-CASPR2), and post-infectious encephalomyelitis (ADEM).
KEY EVIDENCE TO GATHER
-Service treatment records showing injury or complaints
-Imaging (X-ray, MRI, CT)
-Range of motion measurements
-Flare-up documentation per Sharp v. Shulkin
-Buddy statements describing limitations
-Prescription history
-Physical therapy records
-Employment impact documentation
C&P EXAM TIPS (6)
1.Do NOT stretch, warm up, or take pain medication before your exam. The VA needs your baseline limitation.
2.Report your WORST day. DeLuca v. Brown requires documentation of functional loss during flare-ups.
3.Tell the examiner about flare-ups: frequency, duration, estimated ROM loss. Sharp v. Shulkin (2017) requires estimates.
4.Request active, passive, weight-bearing, and non-weight-bearing ROM testing per Correia v. McDonald (2016).
5.If you use assistive devices (brace, cane), bring them.
6.Describe daily activity impact: work, sleep, household tasks.
