The TBI VA claim: how the 10-facet rating system works

If you took a blast, a concussion, a fall, or a hit to the head in service, your traumatic brain injury does not get rated the way most conditions do. There is no single test that spits out a number. Instead the VA breaks your brain down into ten separate areas and grades each one, and that catches a lot of veterans off guard at the decision letter.

Traumatic brain injury, which your paperwork will call TBI, is rated under one diagnostic code: 8045. Once you see how that code works, the odd-looking numbers on your letter start to make sense, and you can tell whether the rating fits how you actually live.

What diagnostic code 8045 actually measures

The rating for TBI residuals lives in the rating schedule at 38 CFR 4.124a. The word "residuals" just means the lasting effects the injury left behind. The code splits those effects into ten areas it calls facets, and a rater grades each one:

• Memory, attention, concentration, and executive functions (planning, organizing, multitasking)
• Judgment
• Social interaction
• Orientation (knowing where you are, the date, who people are)
• Motor activity, when your muscles and nerves themselves are intact
• Visual spatial orientation (getting lost, misjudging distances)
• Subjective symptoms (headaches, dizziness, sensitivity to light or noise)
• Neurobehavioral effects (irritability, impulsiveness, mood swings)
• Communication
• Consciousness

Each facet is scored on a scale of 0, 1, 2, or 3, and the most severe step is labeled "total." Not every facet uses every level. Consciousness, for example, only has "total," because any real disturbance of consciousness is considered totally disabling on its own.

Your highest facet sets the whole rating

This is the part that surprises people. The VA does not average your ten scores and does not combine them. It finds your single highest facet and uses that one to set the overall percentage. In the regulation's own words, you get a 100-percent rating "if 'total' is the level of evaluation for one or more facets." Otherwise, the highest facet maps straight to a number.

That is why a TBI rating only ever comes out as 0, 10, 40, 70, or 100. There is no 20, no 30, no 50. If your memory is graded at a 2 and everything else is a 1, your rating is 40 percent, driven entirely by that one facet. One area at a level 3 gets you to 70, no matter how mild the other nine look.

Your migraines and depression can be rated on top

Here is where a lot of value gets left on the table. A TBI often causes conditions with their own diagnosis and their own diagnostic code. Migraines are the classic one. Depression, seizures, and a sleep disorder are common too. The rule at 38 CFR 4.124a is that the VA rates the physical, the emotional or behavioral, and the cognitive effects of your TBI separately, then combines them under the combined-ratings math, as long as it does not use the same symptom twice.

That last part matters. The VA cannot count the same headache once as a TBI "subjective symptom" and again as a separately rated migraine. Using one symptom to pump up two ratings is called pyramiding, and it is not allowed. But if your migraines are a distinct, diagnosed condition with their own attacks and their own records, they get their own rating that stacks with the TBI rating instead of hiding inside it. Same for depression diagnosed on its own. This is why the diagnosis in your records matters so much: a separate diagnosis can mean a separate rating.

The TBI C&P exam is its own animal

A C&P exam is the Compensation and Pension exam the VA sends you to so an examiner can rate the condition. For an initial TBI claim, VA policy is that the first exam should be done by one of four kinds of specialist: a physiatrist, a psychiatrist, a neurologist, or a neurosurgeon. It is not supposed to be a quick general checkup, because grading those ten facets takes someone trained to do it.

The examiner works through a long questionnaire built around the same ten facets, asking about your memory, your temper, your headaches, your sleep, how you handle a normal day. Whatever comes out of that exam is what the rater uses to score each facet, so the exam is the ballgame. Going in knowing the ten facets, and ready to describe an honest day in each one, is the difference between a rating that fits your life and one that misses it.

Why writing down the daily effects matters

A brain injury does not always look bad for the length of one appointment. You can hold it together for an hour in a quiet exam room and still lose your keys three times a day, snap at your kids over nothing, and forget a conversation from this morning. The exam is a snapshot. Your daily life is the real picture, and the VA can only rate what is written down.

So write it down before the exam. Keep a plain log of what happens: the missed appointments, the notes you leave yourself, the tasks you cannot finish, the times your temper got away from you. A short statement from your spouse, a battle buddy, or a coworker, sometimes called a buddy statement or lay statement, carries real weight, because those people see the facets you might downplay yourself. That everyday detail is exactly what pushes a facet from a 1 to a 2, or a 2 to a 3, which is the difference between 10 percent and 40, or 40 and 70.

Where to verify this yourself

You do not have to take our word for any of it. The full facet table and the rating rules are in the law at 38 CFR §4.124a, Diagnostic Code 8045, and the VA explains its disability rating process on VA.gov. If your TBI rating or a missing residual does not seem to match what those sources say, that is worth raising with a free accredited representative, because errors on complex ratings like this one are common.
