VA Disability Rating for Traumatic Brain Injury (TBI) Residuals

Rated by 10 facets; the highest single facet determines the rating (0/10/40/70/100%). Frequently missed.

TBI residuals (DC 8045) are rated by 10 cognitive/behavioral/physical facets. The highest single facet determines the rating — not the average. Any vet with blast exposure and a post-blast symptom cluster (tinnitus + headaches + memory issues + sleep + mood) should be evaluated for TBI, even years after the fact.

How to get rated for traumatic brain injury (tbi) residuals

  1. C&P exam with TBI specialist — insist on this if exam is scheduled with a non-specialist.
  2. Document the in-service event: IED blast, vehicle rollover, concussive impact, even if not reported at the time.
  3. Neuropsych testing is the strongest objective evidence.
  4. TBI residuals (migraine, tinnitus, cognitive impairment) can be rated separately if they are distinct disabilities.

Common secondary conditions

  • +Migraine
  • +Tinnitus
  • +PTSD (often co-occurring)
  • +Sleep apnea
  • +Depression

File these separately. VA rates each service-connected condition independently and combines them via § 4.25.

Nexus tips

  • Lack of an in-service LOC (loss of consciousness) does NOT defeat a TBI claim. Mild TBI is rated too.
  • Polytrauma profile: if you were near an explosion, document it — TBI + tinnitus + migraines often bundle.

Frequently asked

I never got knocked out. Can I still have TBI?

Yes. Mild TBI (mTBI) does not require loss of consciousness. Repeated subconcussive blast exposure can cause TBI residuals years later.
