How the VA Rates Traumatic Brain Injury
The plain-English version of the 38 CFR § 4.124a, DC 8045 (Evaluation of Cognitive Impairment and Other Residuals of TBI Not Otherwise Classified) criteria a VA rater evaluates Traumatic Brain Injury against, with the 2026 monthly rate at each level. A reference to what the regulation describes — never a prediction of any rating.

The rating levels
Criteria paraphrased from 38 CFR § 4.124a, DC 8045 (Evaluation of Cognitive Impairment and Other Residuals of TBI Not Otherwise Classified) for readability. Monthly amounts are the 2026 rate (effective December 1, 2025) for a veteran with no dependents if this were the only rated condition — dependents add more, and multiple conditions combine under the VA’s own math.
- 100%
$3,938.58/month
Any facet evaluated as "total" (e.g., objective evidence on testing of severe impairment of memory, attention, concentration, or executive functions resulting in severe functional impairment; severely impaired judgment; consistent disorientation to two or more aspects of orientation; complete inability to communicate; or any impaired level of consciousness).
Examples from this level’s criteria
- Severe impairment on neuropsychological testing with severe functional impairment
- Persistent vegetative state or other impaired consciousness
- Usually unable to make reasonable decisions even for routine, familiar matters
- 70%
$1,808.45/month
Highest facet level is 3 (e.g., objective evidence on testing of moderate impairment of memory, attention, concentration, or executive functions resulting in moderate functional impairment; or moderately severely impaired judgment; or often disoriented to two or more aspects of orientation; or neurobehavioral effects that interfere with or preclude workplace or social interaction on most days or occasionally require supervision for safety).
Examples from this level’s criteria
- Moderate impairment shown on neuropsychological testing, with moderate functional impairment
- Occasionally unable to make reasonable decisions even for routine, familiar matters
- Neurobehavioral effects that interfere with or preclude work or social interaction on most days
- 40%
$795.84/month
Highest facet level is 2 (e.g., objective evidence on testing of mild impairment of memory, attention, concentration, or executive functions resulting in mild functional impairment; or three or more subjective symptoms that moderately interfere with work, instrumental activities of daily living, or close relationships; or moderately impaired judgment; or neurobehavioral effects that frequently interfere with workplace or social interaction).
Examples from this level’s criteria
- Mild impairment shown on neuropsychological testing, with mild functional impairment
- Three or more subjective symptoms that moderately interfere (e.g., marked fatigability, blurred or double vision, headaches requiring rest periods during most days)
- Neurobehavioral effects that frequently interfere at work or socially
- 10%
$180.42/month
Highest facet level is 1 (e.g., a complaint of mild loss of memory, attention, concentration, or executive functions but without objective evidence on testing; or three or more subjective symptoms that mildly interfere with work, instrumental activities of daily living, or close relationships; or neurobehavioral effects that occasionally interfere with workplace or social interaction).
Examples from this level’s criteria
- Complaints of mild memory or concentration problems (not yet shown on testing)
- Three or more subjective symptoms that mildly interfere (e.g., intermittent dizziness, daily mild to moderate headaches, tinnitus, frequent insomnia, light or sound sensitivity)
- Irritability or other neurobehavioral effects that occasionally interfere at work or socially
- 0%
$0/month (0% is still service-connected)
Highest facet level is 0 (e.g., memory/attention: no complaints of impairment; subjective symptoms that do not interfere with work, instrumental activities of daily living, or close relationships — such as mild or occasional headaches, mild anxiety).
Examples from this level’s criteria
- Mild or occasional headaches
- Mild anxiety
- Symptoms do not interfere with work, daily activities, or relationships
The listed symptoms are examples that appear in each level’s criteria — not a checklist that earns a percentage. Raters apply the criteria as a whole.
The evidence that matters most
Documentation of the in-service head injury (the event, and any loss of consciousness or altered awareness) plus a TBI/neuro-psych evaluation that describes each facet in the table’s own terms — objective testing where it exists, and the day-to-day residuals (memory, judgment, mood, headaches, dizziness, sleep) in frequency and severity. Migraines, a mental-health condition, or other residuals with their own code are rated separately on top of this
C&P exam tips for Traumatic Brain Injury
- 1Request a comprehensive TBI C&P examination — this must include neuropsychological testing, not just a brief interview.
- 2TBI is evaluated across three domains: cognitive (memory, concentration, processing speed), emotional/behavioral (mood, impulse control, anxiety), and physical (headaches, sleep, sensory, motor). Make sure all three are documented.
- 3Bring a family member or caregiver to the exam if possible — they can describe behaviors you may not recognize in yourself.
- 4Document your worst cognitive days: missed appointments, forgotten names, inability to complete tasks at work.
- 5TBI is a separate condition from PTSD but commonly co-occurs — make sure both are claimed independently.
Common mistakes on Traumatic Brain Injury claims
- Not requesting neuropsychological testing — the brief cognitive screening is insufficient to document impairment at higher rating levels.
- Conflating TBI symptoms with PTSD symptoms — they overlap but should both be documented and rated.
- Not documenting cognitive problems at work specifically (errors, performance issues, inability to manage complex tasks).
- Missing the 'worst day' reporting — describing only the average day undersells the functional impact.
Frequently asked questions
What diagnostic code does the VA use for Traumatic Brain Injury?
Traumatic Brain Injury is rated under 38 CFR § 4.124a, DC 8045 (Evaluation of Cognitive Impairment and Other Residuals of TBI Not Otherwise Classified) — diagnostic code 8045.
What is the highest schedular VA rating for Traumatic Brain Injury?
100% is the highest level in the rating schedule for Traumatic Brain Injury. The criteria at that level describe: Any facet evaluated as "total" (e.g., objective evidence on testing of severe impairment of memory, attention, concentration, or executive functions resulting in severe functional impairment; severely impaired judgment; consistent disorientation to two or more aspects of orientation; complete inability to communicate; or any impaired level of consciousness).
How much does a 100% VA rating for Traumatic Brain Injury pay in 2026?
$3,938.58 per month, tax-free, for a veteran with no dependents (rates effective December 1, 2025) — more with a spouse, children, or dependent parents. If you have other rated conditions, the VA combines ratings using its own math rather than adding them.
