TBI C&P exams are among the most complex in the VA system — the examiner evaluates 10 separate neurobehavioral symptom facets under DC 8045, each rated independently. Many veterans walk in under-prepared and receive ratings far below what their symptoms warrant. This guide walks you through every facet, what the examiner measures, and how to present your worst-day reality accurately.
Traumatic brain injury (TBI) is rated under 38 CFR § 4.124a, Diagnostic Code 8045 using a unique system unlike any other VA disability rating. Instead of a single rating scale, DC 8045 evaluates TBI across ten separate symptom facets — each rated independently from 0 to 3 (mild to severe). The highest single facet rating determines the overall TBI rating, which ranges from 0% to 100%.

| Highest Facet Level | Rating | Monthly Pay (2026) |
|---|---|---|
| Level 1 (mild) in any facet | 0% | $0 (service connected, no pay) |
| Level 2 (mild) in any facet | 10% | $175.51 |
| Level 3 (moderate) in any facet | 40% | $774.16 |
| Level 4 (moderately severe) in any facet | 70% | $1,759.19 |
| Level 5 (severe) in any facet | 100% | $3,737.85 |
This structure means that one severely affected facet can determine your entire rating. A veteran who has severe difficulty with executive function (Facet 6) but mild impairment in other areas is still rated at 100%. Understanding which facets are most severely affected and documenting them accurately is the central challenge of TBI claims preparation.
The VA's TBI rating table evaluates these 10 facets, each on a 0–5 severity scale. Here's what each facet means in practical terms and how to document symptoms for each:
Facet 1 — Memory, Attention, Concentration, and Executive Functions: This is often the most impactful facet for combat veterans with blast-related TBI. The examiner assesses short-term memory (can you recall three words after five minutes?), working memory, attention, and executive function (can you plan, sequence, and complete multi-step tasks?). Describe specific daily failures — forgetting appointments, losing items, needing to write everything down to function, difficulty following complex conversations.
Facet 2 — Judgment: The ability to assess situations, make sound decisions, and anticipate consequences. TBI can impair impulse control and decision-making in ways that look like bad choices to outsiders but reflect genuine neurological dysfunction. Provide examples of poor financial decisions, safety lapses, inability to assess risk appropriately, or impulsive behaviors that have caused problems in your life or relationships.
Facet 3 — Social Interaction: Difficulty with appropriate social behavior — irritability, aggression, social withdrawal, inability to read social cues. TBI commonly causes disinhibition and emotional dysregulation that severely impacts relationships. Describe whether TBI has affected your relationships, whether family members report behavioral changes, and any confrontational incidents or job losses due to interpersonal conflict.
Facet 4 — Orientation: Awareness of person, place, time, and situation. Disorientation can manifest as getting lost in familiar places, losing track of the day or date, or confusion in new environments.
Facet 5 — Motor Activity (including apraxia): Difficulty with purposeful movement or coordination, including fine motor deficits, balance problems, and difficulty with coordinated tasks.
Facet 6 — Visual Spatial Orientation: Difficulty understanding spatial relationships — getting lost, misjudging distances, inability to navigate even familiar routes without GPS.
Facet 7 — Subjective Symptoms: Headaches, tinnitus, dizziness, fatigue, and other subjective complaints that don't fit neatly into the other facets. These are self-reported but taken seriously in the TBI rating system.
Facet 8 — Neurobehavioral Effects: Emotional and behavioral symptoms including depression, anxiety, irritability, aggression, sleep disturbance, and mood lability — the neuropsychiatric consequences of TBI distinct from pre-existing psychiatric conditions.
Facet 9 — Communication: Word-finding difficulty (anomia), disorganized speech, difficulty comprehending complex language. Veterans with significant communication deficits often underreport them because they adapt over time.
Facet 10 — Consciousness: Episodes of altered consciousness, including post-traumatic seizures, episodes of confusion, or dissociation.
A TBI C&P exam is significantly more involved than most VA exams. It is conducted by a VA physician or neuropsychologist trained in TBI evaluation and typically takes 60–90 minutes. The examiner will:

Veterans often unconsciously put their best foot forward at medical appointments. For a VA C&P exam, this is the wrong approach. The VA rates disability — meaning the extent to which the condition prevents you from functioning. Describing your symptoms on a good day gives the examiner an inaccurate picture of your actual disability.
Before the exam, write down:
Bring this written list to the exam and read from it if needed. You are not exaggerating — you are documenting the full picture of your disability.
TBI generates a cascade of secondary conditions, each separately ratable and each worth claiming simultaneously with your primary TBI claim:
| Secondary Condition | VA DC | Notes |
|---|---|---|
| PTSD secondary to TBI | DC 9411 | TBI and PTSD co-occur in 40–50% of combat TBI cases — file separately, watch for pyramiding |
| Major depressive disorder secondary to TBI | DC 9434 | Very common; rated 0–100% based on occupational and social impairment |
| Migraine headaches secondary to TBI | DC 8100 | Rated 0–50% based on frequency of prostrating attacks per month |
| Tinnitus secondary to TBI | DC 6260 | Rated at 10% (single rating regardless of bilateral presentation) |
| Sleep apnea / insomnia secondary to TBI | DC 6847 / DC 6354 | Sleep disruption is common with TBI; sleep study needed for OSA rating |
| Seizure disorder secondary to TBI | DC 8911 | Post-traumatic epilepsy can rate 10–100% based on frequency and type |
Review the headaches secondary to TBI guide and the insomnia secondary to TBI/PTSD guide for evidence strategies on those secondary conditions.
TBI and PTSD share overlapping symptoms — irritability, sleep disturbance, cognitive difficulties, emotional dysregulation, hypervigilance. The VA's anti-pyramiding rule (38 CFR § 4.14) prohibits rating the same symptom twice under two different diagnostic codes. However, TBI and PTSD are not the same condition and can and should be rated separately when they genuinely co-exist.
The key is distinguishing which symptoms are attributable to TBI's neurological mechanism versus PTSD's trauma-based psychological mechanism. A neuropsychologist or psychiatrist familiar with both conditions can provide a clinical opinion distinguishing the two. The DC 8045 TBI rating specifically addresses the neurological facets; DC 9411 PTSD addresses the trauma-based psychiatric symptoms. Symptoms that genuinely overlap should be attributed to the condition that captures them most appropriately — not claimed twice.
The most damaging thing a veteran can do at a TBI C&P exam is present their best-day self. If you've managed to show up, follow the conversation, and answer questions coherently — but your daily reality involves severe cognitive dysfunction — you need to describe that reality explicitly, not implicitly. The examiner sees you for one hour on one day; tell them about all the other days.
Filing for TBI alone without simultaneously filing for migraines, PTSD, depression, and sleep disorders means months of delays and lost back pay. File everything at once — the VA processes them together, and your effective date for all secondary conditions starts from your original filing date.
When you receive your rating decision, request the full examination report (VA Form 21-0781 is not the right form — you need the actual C&P exam report from the VA file). Review whether the examiner addressed all 10 facets, and whether your most severely impaired facets were evaluated at the appropriate severity level. If a facet was underrated, an appeal with neuropsychological testing is your path forward. Use the denial analyzer to identify gaps.
