VA migraine rating: prostrating attacks and DC 8100

The migraine schedule is four lines long and turns on a single word most veterans have never used to describe a headache: prostrating. Knowing what it means, and keeping a record of attacks, helps the file show what the schedule asks.

VA rates service-connected migraines at 0%, 10%, 30% or 50% under diagnostic code (DC) 8100. The tiers turn on how often you have characteristic prostrating attacks, meaning attacks that leave you substantially unable to do ordinary activities. The 50% tier also requires very frequent, completely prostrating and prolonged attacks productive of severe economic inadaptability. Pain intensity alone does not set the rating (38 CFR § 4.124a).

Migraines are rated under diagnostic code 8100 in 38 CFR § 4.124a, the neurological section. Tension and cluster headaches have no diagnostic code of their own. VA can rate an unlisted condition under a closely analogous code (38 CFR § 4.20), and its headache exam form asks the same prostrating-attack questions about tension and cluster headaches as about migraine, so the same prostrating-attack framework in this guide applies to those claims too. Headaches after a TBI are rated under DC 8100 when there is a separate migraine diagnosis, and otherwise as part of the TBI rating (see below and the TBI guide).

In November 2024, VA proposed revising the neurological part of the rating schedule (89 FR 88917). That is a proposal, not current law. As published, it reprints the DC 8100 criteria without change. When this page was reviewed in October 2026, the Federal Register listed no final rule for it, and the current eCFR still shows the four lines below.

The four tiers

Three things decide where you land: whether the attacks are prostrating, how often they happen, and at the top tier, what they do to your ability to work. Pain intensity on its own is not in the schedule. A veteran with daily moderate headaches who pushes through them can be rated 0%. A veteran with one attack a month that puts them in a dark room for six hours matches the 30% line.

What "prostrating" means

The regulation does not define it. VA's adjudication manual (M21-1) and the exam form both use the same definition: "causing extreme exhaustion, powerlessness, debilitation or incapacitation with substantial inability to engage in ordinary activities." In practice that usually describes an attack that forces you to stop what you are doing, often to lie down or rest, until it passes. Light and sound sensitivity, nausea, vomiting, and the inability to function until it passes are common features, and the Veterans Court held in Holmes v. Wilkie (2020) that VA has to weigh all the symptoms of an attack, not just the head pain. Whether a given attack is prostrating depends on how much it limits ordinary activity, which is why describing what you could not do matters more than describing the pain.

Medication is a separate question. DC 8100 does not mention it, and under Jones v. Shinseki (2012) VA may not deny a higher rating because medication eases a condition when the diagnostic code does not account for medication. VA amended its rules to override that on February 17, 2026, then rescinded the amendment on February 27, 2026, restoring the earlier text. If an abortive medication is what keeps an attack from becoming prostrating, the log should say so.

A headache log as evidence

The 10% and 30% tiers are frequencies averaged "over last several months," and the other two tiers are defined against them. That is hard to reconstruct from memory in a short exam, and medical records often miss it, because people do not see a doctor for every migraine. A headache log is useful evidence of frequency, though it is not required and not decisive on its own.

Keep it simple and keep it consistent. For every attack, record the date, how long it lasted, whether you had to lie down, what you missed because of it (work, a shift, a school pickup), and what you took. A log kept as attacks happen is specific, and it lines up with the "average once a month" language the rater applies.

Bring a copy to the C&P exam and submit a copy with the claim. VA's adjudication manual tells raters that a journal kept routinely and close to the time of each attack may be accepted as credible evidence of frequency, prostration, and work impact. A log that shows fourteen prostrating attacks in six months, if the rater finds it credible, documents more than the once-a-month average the 30% line asks for.

The 50% tier and "severe economic inadaptability"

The top tier adds two requirements beyond frequency: the attacks are completely prostrating and prolonged, and they are productive of severe economic inadaptability. The second phrase does not require that you be unemployed.

The Veterans Court made that clear in Pierce v. Principi (2004). "Productive of" can be read as either producing or capable of producing, and nothing in DC 8100 requires a veteran to be completely unable to work. A veteran who is still employed, but only because an employer tolerates missed days, reduced hours, or a role that accommodates the attacks, can meet the standard. What the evidence has to show is that the migraines are severe enough to make holding ordinary employment seriously difficult. Employment records, a supervisor's statement, sick-leave balances, and the log all speak to this. VA's manual adds that attacks logged on non-work days still count toward frequency and prostration but generally say little about work impairment.

Service connection for headaches

Migraines are commonly claimed on three theories:

• Direct. Headache complaints in your service treatment records, even one visit, give the nexus something to attach to. Look for "HA," "cephalgia," or "tension headache" in sick-call notes; the diagnosis does not have to say migraine.
• Secondary. A migraine that a service-connected condition caused or made worse can be service connected on that basis under 38 CFR § 3.310 (for aggravation, only the worsening beyond the baseline level is service connected). The claim needs a medical opinion explaining the mechanism in your case. The secondary conditions guide explains what that opinion has to say.
• TBI residual. Headaches after a documented head injury or blast exposure can be rated as a residual of TBI. When there is a distinct migraine diagnosis, it is rated separately under DC 8100 rather than folded into the TBI rating: the TBI code, DC 8045, tells raters to separately evaluate any residual with a distinct diagnosis that has its own code, and names migraine headache as one example. Headaches without a separate diagnosis are instead counted in the TBI table's subjective-symptoms facet.

Migraines in the combined rating

A 30% migraine rating added to an existing 70% combines to 79%, which rounds to 80%. A 50% rating added to 70% combines to 85%, rounding to 90%. A 10% rating added to the same 70% combines to 73%, which rounds back down to 70%, so moving a migraine rating from 10% to 30% is the difference between a combined 70% and 80%. The combined rating guide shows the arithmetic, and the calculator does it for you.

The checklist

1. A current diagnosis of migraine or headache disorder from a treating provider, with the treatment plan (preventives, abortives) documented.
2. A headache log covering at least the last several months: date, duration, prostrating or not, what was missed.
3. In-service headache complaints from STRs, or a nexus opinion on a secondary theory.
4. Employment evidence if you are claiming 50%: leave records, a supervisor's statement, accommodations.
5. Your own statement describing a typical attack in functional terms: what it stops you from doing, for how long.
