Rating criteria (38 CFR Part 4)
Diagnostic code 8045 — Residuals of Traumatic Brain Injury (TBI) — covers cognitive, emotional, and physical symptoms resulting from head trauma, listed under 38 CFR § 4.124a.
TBI residuals can be rated from 0% to 100% using a complex 10-facet evaluation considering memory, attention, executive functions, judgment, social interaction, orientation, motor activity, visual-spatial abilities, subjective symptoms, and neurobehavioral effects.
For a comprehensive guide with visual compensation breakdowns, secondary conditions, evidence strategies, and claim timelines, visit the detailed guide page for this condition.
Exact rating criteria: The rating is based on three levels of severity across 10 areas of functioning: 0% for no symptoms, 10% for subjective symptoms only, 40% for one or two areas rated as level 2 (moderate impairment), 70% for three or more areas at level 2 or one at level 3 (severe), 100% for two or more areas at level 3.
Effective dates & which schedule version applies
Which diagnostic code, percentage, and effective date apply depends on the facts of your claim and the version of the rating schedule in force for the period being decided. Generally, VA applies the schedule in effect at the specified time under 38 U.S.C. § 5110 and implementing rules, subject to exceptions (e.g., protected ratings, liberalizing law changes—see regulation and VA manual policy as applicable).
For older claims, the **current** eCFR may not match the text that applied years ago. If your decision references a prior percentage or code, compare against the Part 4 text **as of** your claim’s relevant dates; historical Federal Register / CFR snapshots may be needed for precise comparison.

Notes for your claim
Evidence: Show that your diagnosis and severity match the factors the schedule names for DC 8045 (e.g., measurements, frequency, treatment, functional loss), with medical and lay evidence as appropriate.
C&P exams: Results should reflect the schedule’s requirements (correct joints measured, correct formulas). If the exam omits required findings, consider submitting records or requesting clarification.
If you disagree with the DC, percentage, or effective date, review the Part 4 text for your period and consider a supplemental claim or appeal with a VA-accredited representative.
