TBI DBQ Field Guide

9 min read · CFR-cited · 2026 schedule

The TBI DBQ works unlike any other form in the schedule. Residuals of a traumatic brain injury are rated under 38 CFR § 4.124a, Diagnostic Code 8045 across ten separate “facets” of cognitive and behavioral function. Each facet is scored on a ladder — 0, 1, 2, 3, or “total” — and here is the part that matters most: your overall rating is set by the single highest facet, not by an average. One severely-impaired facet drives the entire evaluation.

The mapping: highest facet level 0 → 0%; level 1 → 10%; level 2 → 40%; level 3 → 70%; a facet rated “total” → 100%. Note the jump from level 1 (10%) to level 2 (40%) — getting one facet correctly scored at level 2 instead of 1 is a 30-point swing.

The ten facets the examiner scores

The DBQ asks the examiner to rate each of these from 0 (normal) up to 3 or “total”:

  1. Memory, attention, concentration, executive functions — the most commonly elevated facet.
  2. Judgment — ability to make reasonable decisions, including in complex or unfamiliar situations.
  3. Social interaction — how often behavior is inappropriate.
  4. Orientation — to person, place, time, and situation.
  5. Motor activity — with intact motor and sensory systems (apraxia).
  6. Visual spatial orientation — getting lost, difficulty with directions.
  7. Subjective symptoms — headaches, dizziness, fatigue, sensitivity to light/sound.
  8. Neurobehavioral effects — irritability, impulsivity, aggression, lack of motivation.
  9. Communication — ability to comprehend and express spoken and written language.
  10. Consciousness — altered states; this facet is scored only as “normal” or “total.”

How a facet climbs the ladder

Using the cornerstone facet — memory/attention/concentration/executive function — as the example, the levels read roughly like this:

Level 0 → 0%No complaints; testing normal

Subjective complaints but objective testing is normal, with no functional impairment.

Level 1 → 10%Mild impairment on testing, no work impact

A mild, objectively-shown impairment of memory, attention, or executive function, but it does not interfere with work, social, or daily activity.

Level 2 → 40%Objective impairment that interferes with some activities

Objectively-shown moderate impairment that interferes with work, social functioning, or instrumental activities of daily living, though the veteran can generally function independently with some difficulty.

Level 3 → 70%Severe impairment requiring assistance

Severe impairment that requires assistance, or makes the veteran unable to perform some activities of daily living without help.

Total → 100%Unable to function

Total impairment of the facet — e.g., a persistent altered state of consciousness, or being completely unable to communicate.

The mental-health / TBI overlap rule

Many TBI residuals (irritability, memory, mood, concentration) also look like mental-health symptoms. Under DC 8045, if you have a separately diagnosed mental-health condition (PTSD, depression), the VA evaluates the emotional/behavioral symptoms under § 4.130 (the mental-disorders formula) and the cognitive/physical TBI residuals under DC 8045 — and may assign separate ratings, as long as it does not count the same symptom twice (pyramiding, § 4.14). Make sure the examiner and rater distinguish which symptoms belong to which diagnosis so you are not under-rated by having everything lumped into one.

What to surface at the exam (and in the record)

Magic words for this tier

Aim each statement at the facet it supports:

  • Memory/executive: “I lose track of tasks, miss appointments, and can’t follow multi-step instructions at work.”
  • Judgment: “I make decisions I later realize were unreasonable; I need others to check me.”
  • Neurobehavioral: “I have unprovoked irritability and impulsivity that have cost me relationships and jobs.”
  • Subjective: “I have daily headaches, dizziness, fatigue, and sensitivity to light and noise.”
  • Visual spatial: “I get lost driving familiar routes.”

Each facet is scored on its own merits, so describing your worst-functioning facet in concrete, functional terms is how you protect the rating — because that one facet sets the whole tier.

What NOT to say

What NOT to say

  • “I’ve learned to work around it.” (Compensating strategies read as no impairment — describe the underlying deficit.)
  • “It’s about the same as everyone my age.” (Normalizes a ratable deficit.)
  • “Just headaches.” (Subjective symptoms are a full facet — describe frequency and severity.)
  • “My memory’s fine, I just write things down.” (The writing-down is the impairment.)

Bring objective support

Neuropsychological testing, a treating-provider statement, and a family lay statement describing day-to-day functioning all help the examiner score the facets accurately. The DBQ asks for objective findings — testing results that show a level 2 impairment are far stronger than subjective report alone.
