TBI Residuals (Cognitive) VA Disability Rating is rated by the U.S. Department of Veterans Affairs under DC 8045 of 38 C.F.R. § 4.124a across 4 severity tiers (100% -- Total impairment / 70% -- Level 3 impairment / 40% -- Level 2 impairment / 10% -- Level 1 impairment). 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.
TBI cognitive residuals are rated under DC 8045 using a 10-facet evaluation: memory, attention, concentration, executive functions, judgment, social interaction, orientation, motor activity, visual-spatial, neurobehavioral effects. The highest facet level determines the rating.
TBI Residuals (Cognitive) (DC 8045) is evaluated under 38 C.F.R. § 4.124a using the brain injury rating framework. Because it is rated by analogy to the general schedule, the 4 levels below describe the body-system criteria the VA applies — the percentage assigned to TBI Residuals (Cognitive) depends on the specific findings (range of motion, frequency, severity, or functional loss) documented at the C&P exam and in the medical record.
