A migraine VA rating often comes down to a single word the VA uses but rarely explains well: prostrating. Migraines are one of the most common conditions veterans claim — and one of the most frequently under-rated, because veterans don’t document their attacks in the specific way the VA’s rating criteria require. This guide breaks down how migraines are rated, what “prostrating” actually means, and how to prove the rating you deserve.

How Migraines Are Rated: Diagnostic Code 8100
The VA rates migraines under 38 CFR 4.124a, Diagnostic Code 8100. There are four levels — 0%, 10%, 30%, and 50% — and the rating depends on how often you have “prostrating” attacks and how much they affect your ability to work.
- 0%: Migraines are diagnosed, but with less frequent attacks (not prostrating enough or frequent enough to be compensable).
- 10%: Characteristic prostrating attacks averaging one every two months over the last several months.
- 30%: Characteristic prostrating attacks occurring on average once a month over the last several months.
- 50%: Very frequent, completely prostrating, and prolonged attacks productive of severe economic inadaptability.
50% is the highest schedular rating for migraines. Note that these criteria are “successive” — to qualify for a higher level, you must also meet the levels below it. The whole scale turns on frequency and that one key word.
What “Prostrating” Actually Means
This is where most veterans lose rating points. The VA’s M21-1 guidance and case law define “prostrating” as an attack causing extreme exhaustion, weakness, or powerlessness — one that leaves you substantially unable to carry on ordinary activities. In practical terms: a prostrating migraine is one that forces you to stop what you’re doing and lie down, often in a dark room, until it passes.
“Completely prostrating” (required for 50%) means the attack renders you essentially powerless, and “prolonged” means it lasts an extended time. A headache you can push through while working is generally not prostrating in the VA’s eyes — which is why simply having frequent headaches isn’t enough. The record has to show the attacks knock you out of normal function.
The “Severe Economic Inadaptability” Hurdle for 50%
The 50% rating adds one more requirement: the attacks must produce “severe economic inadaptability” — meaning significant impairment of your ability to work. It does not require total unemployability, but it does require showing real impact on work. Migraines documented on non-work days can help prove frequency and prostration, but they don’t directly show work impact — so documenting attacks that affect your job is especially important at this level.
How to Document Migraines for a Higher Rating
The strongest migraine claims read like a timeline, not a complaint. To support your rating:
- Keep a migraine log. Record each attack — date, duration, symptoms, what you had to stop doing, whether you missed work. Consistent dated entries are powerful evidence of frequency and prostration.
- Get attacks into your medical records. Tell your provider about each significant migraine so it’s documented contemporaneously, not just recalled later.
- Show the work impact. Missed shifts, used sick leave, or accommodations all help establish economic inadaptability for the higher ratings.
- Use lay evidence. A buddy statement from a spouse or coworker describing your attacks can corroborate what your records show.
Migraines as a Secondary Condition
Migraines are very commonly claimed as a secondary condition — frequently secondary to service-connected PTSD, tinnitus, or a head/neck injury. If you already have one of those service-connected, and migraines developed as a result, that’s a viable secondary claim. And once rated, your migraine percentage combines with your other ratings through VA math.
The Bottom Line
Your migraine VA rating lives or dies on documentation of “prostrating” attacks and their frequency. Levels run 0/10/30/50 under DC 8100, with the 50% level also requiring proof of severe economic inadaptability. Keep a detailed log, get attacks into your medical records, and show how they affect your work. For the full picture of how claims work, start with our walkthrough of how VA disability claims work.
