Understanding Your Migraine DBQ
One word decides this rating
Every tier of the migraine rating turns on a single word: prostrating.
It is not a word most people use, and it does not mean "bad." VA prints its own definition on the form itself, in the section that matters most:
"For VA purposes, the term prostrating means 'causing extreme exhaustion, powerlessness, debilitation or incapacitation with substantial inability to engage in ordinary activities.'"
Read that again, because it is the whole claim. A prostrating attack is one that stops you. Not one you push through. Not one you take something for and keep working. One where you cannot do the ordinary things you would otherwise be doing.
Here is the problem this creates. Veterans are, as a group, stoic about pain. Asked how bad the headaches are, a lot of people say "pretty bad" about an attack that put them in a dark room for six hours unable to speak to anyone. The examiner writes down what they hear. And "pretty bad" is not prostrating.
If your attacks stop you, say so in those terms: I cannot function. I have to lie down in the dark. I cannot work, drive, or take care of anything until it passes. That is not exaggeration — it is the vocabulary the form is asking for, and VA supplied the definition.
How the ratings work
Diagnostic Code 8100 — Migraine
| What the evidence shows | Rating |
|---|---|
| Very frequent completely prostrating and prolonged attacks productive of severe economic inadaptability | 50% |
| Characteristic prostrating attacks occurring on an average once a month over the last several months | 30% |
| Characteristic prostrating attacks averaging one in 2 months over the last several months | 10% |
| Less frequent attacks | 0% |
Notice what this rating is built from: frequency and severity, averaged over months. Not a test result. Nothing about the exam room itself. That is why the record you bring matters more here than almost anywhere else in the schedule.
About the 0%. A 0% rating is not a denial. It means VA agrees the condition is connected to your service but is not currently compensable. That agreement has real value — if the migraines worsen, you are asking VA to increase an established rating rather than starting a new claim from nothing. Veterans are often told they "lost" when they got a zero. They did not.
The two questions that are the rating
Section IV of the DBQ is the whole ballgame. It contains two questions, and the form explicitly instructs the examiner to complete both.
4A — characteristic prostrating attacks. Does the veteran have them, and how often on average over the last several months? The options are: with less frequent attacks · once in 2 months · once every month · greater than once per month.
4B — completely prostrating and prolonged attacks. Same question, same four frequency options, but a higher bar: attacks that are completely prostrating and prolonged.
Compare those options to the rating table above and you will see they are the criteria, almost word for word. 4A establishes the 10% and 30% tiers.
4B is the only path to 50%. It is the only question on the form that asks about attacks being completely prostrating and prolonged, which is what the 50% criterion requires.
So here is the single most important thing on this page:
If the examiner completes 4A and leaves 4B blank, your rating is capped at 30% — no matter how severe your migraines actually are.
That is one unchecked box between a 30% and a 50% evaluation. The form tells the examiner to answer both. If your attacks genuinely leave you completely incapacitated for extended periods, make sure that gets described clearly enough that 4B gets answered.
The 50% rating needs a second section
There is a second half to the 50% criterion that Section IV never asks about: the attacks must be "productive of severe economic inadaptability."
Nothing in the prostrating-attacks section addresses work. That comes from Section VII — Functional Impact, which asks whether the headache condition affects your ability to work and asks for examples.
So a 50% case is assembled from two places on the form: 4B for the severity and frequency, Section VII for the economic consequence. An examiner who answers 4B accurately and writes two words in Section VII has documented half the criterion.
Come prepared with specifics. Shifts you missed. Days you left early. Work you turned down or could not take. A job you lost. Accommodations you had to ask for. Concrete examples, with rough dates. "It affects my work" is not evidence; "I missed eleven days last year and moved off the early shift because of them" is.
What else the form asks
Diagnosis. Which headache condition — migraine including variants, tension, cluster, or other — with ICD codes and date of diagnosis.
Medical history and treatment. Including whether you take continuous medication for the condition. Worth noting: needing daily preventive medication is itself part of the picture of how much the condition governs your life.
Symptoms. The character of the pain — constant, pulsating or throbbing, one-sided or both, worsening with activity — and the non-headache symptoms that come with it: nausea, vomiting, sensitivity to light, sensitivity to sound, vision changes such as scotoma or flashes, sensory changes. Also typical duration (less than a day, 1–2 days, more than 2 days) and location.
Those duration and symptom fields matter more than they look. "Prolonged" appears in the 50% criterion, and a recorded typical duration of more than two days supports it.
Functional impact. Discussed above — the section that carries the economic half of the 50% criterion.
Scars, other findings, diagnostic testing, remarks. The form notes that diagnostic testing is not required for this examination; if studies exist, results go in.
What "good" documentation looks like
A strong migraine DBQ answers both 4A and 4B, with frequencies that match a real record rather than a guess; records typical duration accurately; captures the associated symptoms; and fills Section VII with concrete work consequences.
A weak one answers 4A only, records "headaches, frequent," and leaves functional impact blank.
How to prepare, and how to check afterward
Before the exam, bring your headache diary — dates, durations, and what each attack stopped you from doing. If you have not started one, start now; even a few weeks of dated entries beats memory. Bring anything showing work impact: attendance records, emails about missed shifts, a note from a supervisor or spouse who has seen you during an attack.
When you get the completed DBQ back, check three things:
- Is 4B answered — not just 4A?
- Does the recorded frequency match what your diary actually shows?
- Does Section VII contain real examples, or is it thin?
If the frequency on the form is lower than your record supports, or 4B is blank when your attacks genuinely are completely prostrating and prolonged, that is worth raising with an accredited representative.
A note on honesty
None of this is about overstating a condition. It is about describing one accurately in the vocabulary VA actually uses, because the words in the rating schedule are narrower than everyday speech. Overstating your symptoms is both wrong and, on a claim decided by consistency across months of records, self-defeating. Describe what genuinely happens — and use their word for it when it fits.
