Traumatic Brain Injury VA Disability Rating
- Service connection requires a current diagnosis, an in-service event or exposure, and a medical link (nexus) between the two.
- VA assigns ratings of 0% to 100% under diagnostic code 8045, using the criteria in the rating table below.
- The percentage assigned turns on The worst-affected area of function.
- Measured at the C&P exam: Neurological exam: motor, sensory, reflexes.
| Rating | Criteria |
|---|---|
| 0% | All facets normal. |
| 10% | Mild impairment in one facet. |
| 40% | Moderate impairment in any facet. |
| 70% | Severe impairment in any facet. |
| 100% | Total impairment in any facet. |
Illustrative scenarios showing how the criteria above are applied. These are educational examples, not a prediction of any individual veteran's rating.
Mild memory and concentration trouble after a head injury
Illustrates 10%Situation. A veteran has mild memory and concentration problems after a documented head injury in service.
How the criteria apply. TBI residuals are rated across ten facets of function, and the single worst-affected facet drives the rating. Mild impairment in one facet rates 10 percent. Concrete daily examples beat labels here.
Severe problems in one area of function
Illustrates 70%Situation. A veteran has severe problems in one facet, such as frequently getting lost or being unable to follow a conversation.
How the criteria apply. Severe impairment in any one facet rates 70 percent. Headaches, mood changes, or other residuals tied to the injury can carry separate ratings of their own.
TBI residuals are complex because they cross cognitive, emotional, and physical domains. The exam matters a lot.
What VA looks at
Memory, attention, executive function, judgment, social interaction, orientation, motor activity, visual spatial orientation, communication, consciousness.
Common exam and DBQ topics
Cognitive testing, daily functioning, headaches, mood, sleep.
Evidence that usually matters
Neuropsychological testing, neurology notes, in service event documentation.
Common misunderstandings
Symptoms also rated under mental disorders should be evaluated to avoid pyramiding.
Drawn directly from the VA Disability Benefits Questionnaire (DBQ). The examiner records each item below; the rating then maps to the table above.
- Confirm history of head injury, mechanism, and any loss of consciousness, post-traumatic amnesia, or alteration of consciousness.
- Evaluate the ten TBI facets used to rate residuals (38 CFR 4.124a, DC 8045): memory/attention/concentration/executive function, judgment, social interaction, orientation, motor activity, visual spatial orientation, subjective symptoms, neurobehavioral effects, communication, and consciousness.
- Score each facet on a 0-3 scale; the highest single facet score generally drives the rating (0, 10, 40, 70, 100 percent).
- Identify separately ratable physical or emotional residuals (migraines, peripheral nerves, hearing loss, vision loss, mental disorders) that should be rated separately rather than combined into the TBI rating.
- Document need for assistive devices and impact on employment and daily activities.
Small rules in the regulations decide a surprising number of claims. These are the ones that most often change a traumatic brain injury outcome. None of this is legal advice; it is a map of where to look.
TBI is scored across ten thinking areas, and your level is set by your single worst area, not an average. A finding of total on any one area means a 100 percent rating.

38 CFR 4.124aWas this helpful?
- What you and people around you witnessed is real evidence
You do not always need a doctor to prove a symptom you can see, hear, or feel. Statements from you, family, or fellow service members about things like pain, ringing in the ears, or panic attacks are competent lay evidence under 38 CFR 3.159. A clear buddy statement with dates and specifics can carry weight.
38 CFR 3.159 - A tie goes to you
When the evidence for and against a point is roughly equal, VA is required to decide in the veteran's favor. This benefit of the doubt rule lives in 38 CFR 3.102. You do not have to prove a claim beyond all doubt, only to bring the evidence to about even.
38 CFR 3.102 - An unbroken line of symptoms can stand in for a paper trail
For certain chronic conditions, showing symptoms that continued from service to now can help establish service connection even without a perfect record. This continuity of symptomatology idea comes from 38 CFR 3.303(b) and applies to the chronic diseases the regulation lists.
38 CFR 3.303 - If it happened in combat, your word can be enough that the event occurred
For anyone who served in combat, VA must accept your own account of what happened during that combat as proof the event took place, as long as it fits the conditions of your service, even when no record survives. This comes from 38 U.S.C. 1154(b). It does not by itself prove the injury, but it can establish the in service event.
38 U.S.C. 1154(b) - If it was not written down at entry, you are presumed to have entered healthy
Unless a condition was noted on your entrance exam, the law presumes you were sound when you entered service. To rebut that, VA has to show by clear and unmistakable evidence both that the condition existed before service and that service did not make it worse. See 38 CFR 3.304(b).
38 CFR 3.304 - You can reopen a denied claim with new and relevant evidence and keep your date
After a decision, a Supplemental Claim lets you add new and relevant evidence. If you file it within one year of the decision, you protect your original effective date, so back pay can reach further. See 38 CFR 3.2501.
38 CFR 3.2501 - Some conditions are presumed if they show up within a year of getting out
Certain chronic diseases, including hypertension, arthritis, and diabetes, that appear to a compensable degree within one year of leaving service are presumed connected to service, even without proof of a specific cause. See 38 CFR 3.307 and the list in 3.309.
38 CFR 3.309 - A diagnosis years later can still be service connected
A condition first diagnosed long after you left service can still be service connected if the evidence ties it back to something in service. You do not need a diagnosis while still in uniform. See 38 CFR 3.303(d).
38 CFR 3.303
- The same symptom is rated once, but separate problems are rated separately
VA cannot rate the same symptom twice, which is pyramiding under 38 CFR 4.14, but it can and should rate distinct problems on their own. A scar and the loss of motion under it, for example, can each be rated. The Esteban decision is the classic example.
38 CFR 4.14 - One service connected condition can open the door to another
A condition caused by, or made worse by, a service connected condition can be service connected too. Sleep apnea linked to weight gain from a service connected condition, or depression linked to chronic pain, are common examples. This secondary path is in 38 CFR 3.310.
38 CFR 3.310 - Your rating can change by time period
If a condition was worse during one stretch and better during another, VA can assign different ratings for those periods rather than one flat number. These are called staged ratings, and they flow from VA's duty to consider the whole recorded history under 38 CFR 4.1 and 4.2.
38 CFR 4.2 - Ratings are combined with a table, not added
Two disabilities at 50 and 50 do not make 100. VA combines them with the table in 38 CFR 4.25, working from the largest down, then rounds to the nearest 10 only at the very end. This is why a 30 and a 20 can land on 40, not 50.
38 CFR 4.25 - If the schedule does not fit your case, VA can rate outside it
When your disability picture is so unusual that the normal rating schedule does not capture it, for example frequent hospital stays or marked interference with work, VA can refer the case for an extraschedular rating. It is uncommon but real, under 38 CFR 3.321(b)(1).
38 CFR 3.321 - When you are between two ratings, the higher one should win
If your symptoms sit between two rating levels, VA is supposed to assign the higher one when your overall disability picture more nearly matches it. This is the reasonable doubt rule applied to ratings, in 38 CFR 4.7.
38 CFR 4.7 - You do not have to check every box on the list
The symptoms listed at each rating level are examples and guides, not a strict checklist. VA is not supposed to deny a level just because you do not have every single symptom named. See 38 CFR 4.21.
38 CFR 4.21
- You can lock in your start date before the full claim is ready
Filing an intent to file holds your effective date for up to a year while you gather evidence. If you complete the claim within that year, back pay can run from the intent to file date, not the later submission. See 38 CFR 3.155.
38 CFR 3.155 - Older ratings get harder to take away
A rating in place for 5 years is treated as stabilized, one in place for 10 years has protected service connection, and one in place for 20 years generally cannot be reduced below its level except for fraud. See 38 CFR 3.344, 3.957, and 3.951.
38 CFR 3.344 - VA cannot cut a rating without showing real, lasting improvement
To reduce a rating, VA generally has to show actual improvement under the ordinary conditions of life and work, not just one better exam. The rules are in 38 CFR 3.344, and a proposed reduction comes with notice and a chance to respond first.
38 CFR 3.344 - You can be paid at the 100 percent rate without a 100 percent rating
If service connected conditions keep you from holding steady, gainful work, VA can pay you at the 100 percent rate through TDIU, even if your combined rating is lower. Under the Rice decision, VA must consider TDIU whenever the record raises it, even if you never asked for it by name. See 38 CFR 4.16.
38 CFR 4.16 - Your back pay date is worth checking yourself
Your award usually runs from the date you filed or the date entitlement arose, whichever is later, with special rules for claims filed within a year of leaving service. Knowing your effective date under 38 CFR 3.400 is how you catch retroactive pay that came up short.
38 CFR 3.400 - A clear error in an old decision can be fixed back to day one
A final decision that contained a clear and unmistakable error can be revised at any time, and the correction runs back to the original date, not the date you pointed out the error. The bar is high: the error has to be undebatable. See 38 CFR 3.105(a).
38 CFR 3.105 - Needing help at home can add money on top of your rating
If you need help with everyday activities, or are largely confined to your home because of disability, you may qualify for Aid and Attendance or Housebound payments added to your monthly amount. See 38 CFR 3.350 and 3.352.
38 CFR 3.352 - Surgery can earn a temporary 100 percent rating while you heal
After certain surgeries, or when a service connected joint is immobilized in a cast, VA can grant a temporary 100 percent rating during recovery and then return you to your prior rating. It is easy to miss because you have to flag it. See 38 CFR 4.30.
38 CFR 4.30 - A long hospital stay can pay at 100 percent for that time
If you are hospitalized more than 21 days for a service connected condition, VA can pay you at the 100 percent rate for that period, then drop back to your regular rating afterward. See 38 CFR 4.29.
38 CFR 4.29 - Even a 0 percent rating is worth winning
A 0 percent rating still confirms the condition is service connected. That opens the door to secondary claims, to an increase later if it worsens, and can affect VA health care priority. Do not walk away from a noncompensable grant. See 38 CFR 4.31.
38 CFR 4.31 - A new law can pay you back to its start date
When a new law or presumption adds a condition, your benefits can reach back to the law's effective date, up to one year before you filed. This matters for PACT Act and other presumptive expansions. See 38 CFR 3.114.
38 CFR 3.114 - If VA later finds lost service records, your date can reach back
When VA later locates relevant official service records it did not have the first time, it must reconsider the claim, and the effective date can run back to your original filing, even years later. See 38 CFR 3.156(c).
38 CFR 3.156 - An increase can be backdated up to a year
For a condition that got worse, your higher rating can be paid up to one year before you filed, if the record shows the worsening was clearly there during that window. See 38 CFR 3.400(o)(2).
38 CFR 3.400 - One total rating plus 60 percent more can mean extra money
If you have a single disability rated 100 percent and other service connected disabilities adding to 60 percent or more, you may qualify for housebound special monthly compensation, paid on top of the 100 percent rate. See 38 CFR 3.350(i).
38 CFR 3.350
- Mental health ratings turn on daily life, not the label
VA rates a mental health condition by how much it impairs work and social functioning, using the General Rating Formula in 38 CFR 4.130, not by the diagnosis name. Describing concrete effects on sleep, focus, mood, and getting along with people matters more than the exact term used.

How does VA rate a traumatic brain injury?
VA looks at ten areas of function, like memory, judgment, attention, and mood, and rates the one that is most affected. Those areas translate to ratings of 0, 10, 40, 70, or 100 percent, with the worst single area generally driving the result.
What if my TBI symptoms overlap with PTSD?
This is common, and it can get tricky. Some symptoms, like trouble concentrating or irritability, can come from either condition. VA tries not to rate the same symptom twice, so a careful exam that sorts out which condition causes what protects you from being underrated.
Are TBI effects considered lasting?
They can be. Many residual effects of a moderate or severe TBI persist for years, and VA can recognize that. Keeping current medical records that show the ongoing impact is what supports a stable, accurate rating over time.
You have three review lanes, pick the one that fits the situation.
Under the Appeals Modernization Act (38 CFR 3.2500), a Higher Level Review or a Board Appeal must be requested within one year of the decision notice. A Supplemental Claim can generally be filed at any time after the decision, but filing any of the three within that one year window is what keeps the claim continuously pursued and protects the original effective date; wait longer and a later award may start from the new filing date instead.

Your VA claims file (the C-File) and your C&P exam reports are the documents VA used to decide your case. You have the right to a copy. Here are the three working request paths in 2026, plus a full guide to what is inside the file, how to read the rating code sheet, and how to use it for an appeal, a supplemental claim, a proposed reduction, or an effective date fight.
TBI residuals are rated under DC 8045 through ten facets, with the single highest facet setting the rating from 0 to 100 percent. Here is the facet table, the testing that separates 10 from 40 percent, and SMC-T, the aid and attendance benefit worth over 11,000 dollars a month that most TBI families never hear about.
Total Disability based on Individual Unemployability lets a veteran be paid at the 100 percent rate even when the schedular combined rating is lower.
Most PTSD claims are won or lost on the stressor. This playbook matches each stressor type to its evidence rule (combat, fear of hostile activity, POW, MST markers), covers VA Form 21-0781, what the C&P examiner must decide, the 50 percent floor when PTSD ends a career, and the record that carries the claim.
Since Feb 19, 2019, a veteran who disagrees with a VA decision picks from three review lanes: Higher Level Review, Supplemental Claim, or Board Appeal. This is a Walkthrough what each lane is, what it requires, what it costs in time, and how to keep your effective date protected.
A Supplemental Claim is filed on VA Form 20-0995 and reopens a prior decision based on new and relevant evidence. This article walks the standard, the duty to assist, the one year window, and what counts as 'new' vs 'relevant' under 38 CFR 3.2501.
What a secondary service connection is, the most common pairings VA actually sees, and what evidence you need to file one.
VA decision letters use a small vocabulary of words that decide everything for years to come: granted, denied, deferred, evaluation continued, remanded. Here is what each one actually means.
The Board of Veterans' Appeals decides cases on three dockets, Direct Review, Evidence Submission, and Hearing. This article walks each docket, the hearing types, the docket math, the role of the Veterans Law Judge, and what happens after a Board decision.
An Other Than Honorable discharge does not always bar VA benefits. Under 38 CFR 3.12, VA reviews the underlying conduct and may find it was not disqualifying. The Hagel and Wilkie memos direct VA to give liberal consideration when PTSD, TBI, or military sexual trauma plausibly contributed to the conduct. Discharge upgrade through DRB or BCMR is a parallel path.
TDIU under 38 CFR 4.16 and a schedular 100 percent rating both pay the same monthly compensation, but they are not the same rating. Five things separate them: reducibility, SMC-S housebound eligibility, CHAMPVA for the family, Dependents Educational Assistance under Chapter 35, and the 8-year DIC additional allowance clock. This article walks through each difference and how to ask VA for a permanence designation when it matters.
C&P examiners describe how veterans walk using exact clinical terms: antalgic, steppage, hemiparetic, Trendelenburg, festinating, sensory ataxic, waddling. Each of those words triggers different parts of the rating schedule. Here is what they mean, why they matter, and how to get the functional-loss credit you have the right to under DeLuca v. Brown.
A proposed-reduction letter is one of the worst pieces of mail VA sends. You have 60 days to send evidence and 30 days to demand a predetermination hearing. Beyond that, 38 CFR 3.344 protects long-standing ratings. Here is the procedural roadmap, the stabilization rules that can stop a reduction cold, and a step-by-step response plan.
Combat rarely leaves a paper trail. Under 38 USC 1154(b) and 38 CFR 3.304(d), a combat veteran's credible account of an in service event is accepted if it fits the circumstances of service, and VA can reject it only by clear and convincing evidence. This article explains what the combat rule proves, what it does not, and how to use it.
A rating can be reviewed, but the law builds in real protections. Here are the 5-year stabilized rating rule, the 10-year rule that protects service connection, the 20-year rule that protects your evaluation level, the age 55 reexamination practice, and what 100 percent Permanent and Total means.
A disability rating can unlock education and training help. Chapter 35 DEA covers dependents and survivors of a permanently and totally disabled veteran, while VR&E (Chapter 31) helps the veteran with an employment handicap train for and keep work. Here is who qualifies for each and how to apply.
The Integrated Disability Evaluation System uses one set of exams for both the DoD fit-for-duty decision and your VA rating. Here is what the Medical Evaluation Board and Physical Evaluation Board do, why the VA number often differs from the DoD number, and what to claim before you separate.
For Guard and Reserve members, the type of duty you were on controls whether something can be service connected, and even whether you are a veteran for VA purposes. Here is how active duty, active duty for training (ACDUTRA), and inactive duty training (INACDUTRA) differ (38 CFR 3.6), and why a heart attack or stroke during drill counts.
Whether you can work depends on how you reached the 100 percent rate. A schedular 100 percent rating has no work limit. TDIU does, because it is paid for being unable to hold substantially gainful work (38 CFR 4.16). Here is the line between substantially gainful, marginal, and protected employment.
Your rating may also qualify you for state-level benefits.
VA compensation is federal, but every state layers its own benefits on top. Many states reduce or waive property tax for disabled veterans, and many offer license, tuition, or vehicle benefits at various rating levels. The thresholds, dollar amounts, and eligibility rules vary widely from state to state, so the reliable answer is always your own state's guide.
