VA Disability for TBI (Traumatic Brain Injury)

Traumatic brain injury (TBI) is one of the signature injuries of modern military service — from blast exposure, vehicle accidents, falls, and combat. Its effects can be subtle or severe and can touch nearly every part of life: memory, concentration, mood, headaches, sleep, and more. The VA rates TBI and its residual effects, and because those effects overlap with other conditions, TBI claims deserve careful attention. Here is how it works.

How the VA rates TBI

TBI is rated under diagnostic code 8045, which evaluates the residuals — the lasting effects of the injury — rather than the original event. The VA breaks the residuals into three areas: cognitive (memory, attention, executive function), emotional/behavioral, and physical. The cognitive residuals are evaluated across a set of facets, each scored by level of impairment, and the highest facet level generally drives the rating, which can be 0%, 10%, 40%, 70%, or 100%. Importantly, emotional and physical residuals that can be separately diagnosed — like migraines or a mental health condition — are often rated separately rather than folded into the TBI rating, which can meaningfully increase a veteran’s overall evaluation. Our overview of how VA disability ratings work explains how these combine.

TBI and overlapping conditions

One of the most important — and complicated — aspects of TBI claims is the overlap with mental health conditions. TBI and PTSD frequently coexist, and because some symptoms overlap (irritability, sleep problems, concentration difficulty), the VA has specific rules for how they are evaluated together so that you are properly compensated. Similarly, post-traumatic headaches and migraines are a very common TBI residual that may warrant their own rating. Making sure each distinct, separately-diagnosable residual is identified and claimed is central to getting a fair overall evaluation.

Proving your TBI claim

You need a diagnosis of TBI and evidence of the in-service event that caused it — blast exposure, a documented accident, a combat incident, or similar — plus documentation of the residuals you live with now. Service records, buddy statements, and any in-service medical treatment help establish the event; current neurological, neuropsychological, and mental health evaluations document the residuals. Because residuals can be wide-ranging, a thorough record that captures all of them is essential. A nexus letter can help connect current symptoms to the in-service injury.

The C&P exam

TBI residuals are typically evaluated by an appropriately qualified examiner. At your C&P exam, describe the full range of how the injury affects you — memory lapses, trouble focusing, word-finding problems, irritability, headaches, dizziness, light or noise sensitivity, fatigue, and sleep issues. Do not downplay symptoms or push through them to appear capable; the examiner needs an accurate picture of your daily reality. Review what not to say at a C&P exam beforehand.

Tips to strengthen your claim

Document the causing event as thoroughly as you can; get current cognitive and mental health evaluations; identify every residual and make sure separately-ratable ones (migraines, a mental health condition) are claimed in their own right; and describe the day-to-day impact in concrete terms, ideally backed by statements from people who knew you before and after. For veterans pursuing the highest evaluations, our guide to getting a 100% VA disability rating explains how multiple ratings can combine. If denied or underrated, see how to increase your rating.

Why TBI claims are often underrated

TBI is one of the most commonly underrated conditions, and understanding why helps you avoid the traps. The core issue is that the injury produces a wide range of residuals across cognitive, emotional, and physical domains, and it is easy for several of them to go unidentified or unclaimed. A veteran who reports only memory problems may miss that their post-traumatic migraines, their mood condition, their dizziness, or their sleep disturbance can each be evaluated — and that the separately-diagnosable residuals are often rated on their own, raising the overall evaluation rather than being absorbed into a single TBI percentage. Another trap is the overlap with PTSD: because the symptoms blur together, claims can be processed in a way that shortchanges the veteran unless the distinct conditions are clearly documented. Veterans also tend to push through cognitive and emotional symptoms to appear capable, which leads examiners to underestimate the true impact. The remedy is thoroughness: get appropriate neurological, neuropsychological, and mental health evaluations; identify and claim every residual; make sure separately-ratable conditions like migraines are filed in their own right; and be candid about the daily reality at the exam. Statements from people who knew you before and after the injury can powerfully document changes you may not fully see in yourself. Treating a TBI claim as a collection of residuals to be fully captured — not a single injury — is what produces a fair rating.

Key takeaways

• TBI is rated under code 8045 by its residuals — cognitive, emotional, and physical — at 0, 10, 40, 70, or 100%.
• Separately-diagnosable residuals like migraines or a mental health condition are often rated on their own, raising the overall evaluation.
• TBI and PTSD frequently overlap and have specific rules for being evaluated together.
• Document the causing event and every residual thoroughly, and be candid at the C&P exam.

Frequently asked questions

How does the VA rate TBI? By the residual effects under code 8045 — cognitive facets plus emotional and physical residuals — at levels of 0, 10, 40, 70, or 100%.

Can TBI and PTSD both be rated? Yes — they often coexist, and the VA has specific rules so overlapping symptoms are evaluated fairly without simply collapsing one into the other.

Are TBI headaches rated separately? Often yes — post-traumatic migraines are a common residual that can warrant their own rating in addition to the TBI evaluation.

Should I get a private neuropsychological evaluation? It can help — a thorough neuropsychological evaluation documents the cognitive residuals in detail, which is exactly what the TBI rating facets measure, and it can support a more accurate evaluation.
