How to file a VA migraine claim — DC 8100, what "prostrating" and "severe economic inadaptability" mean, the headache log and secondary routes
Migraine is rated under 38 CFR 4.124a, diagnostic code 8100, entirely by the frequency and effect of prostrating attacks: 0% with less frequent attacks, 10% with characteristic prostrating attacks averaging one in two months over the last several months, 30% with characteristic prostrating attacks averaging once a month over the last several months, and 50% with very frequent completely prostrating and prolonged attacks productive of severe economic inadaptability. Service connection can be direct (headaches documented in service or linked to an in-service injury) or secondary under 38 CFR 3.310 to a service-connected condition such as traumatic brain injury, PTSD, neck injury or sleep apnea, with a nexus opinion that the link is at least as likely as not. Because the rating turns on how often attacks force you to stop and lie down, a dated headache log and statements from people who see the attacks are the evidence that matters.
What you'll need
- VA Form 21-526EZ (or VA Form 20-0995 if VA denied headaches before)
- Current diagnosis of migraine (or other headache disorder) from a VA or private clinician, with treatment records
- A dated headache log showing each attack, its length, whether you had to stop and lie down, and missed work
- Service treatment records showing headaches, head or neck injury, or blast exposure; for a secondary claim, the rating decision for the primary condition
- A nexus opinion for a secondary or undocumented claim; statements from family or coworkers
- A free accredited representative (CVSO or VSO)
Step-by-step
Step 1: Pick the route to service connection
Direct: headaches noted in service treatment records, or that began after an in-service head or neck injury, with a current diagnosis and continuity since. Secondary (38 CFR 3.310): post-traumatic headache after a service-connected TBI, headaches tied to a service-connected cervical spine condition, to PTSD or its medications, or to service-connected sleep apnea — each needs a clinician's opinion that the service-connected condition caused or aggravated the headaches, with a rationale. Headaches first treated within a year of separation can also support a direct claim with a nexus opinion.
Step 2: Understand the DC 8100 criteria
The four levels are: 0% — less frequent attacks; 10% — characteristic prostrating attacks averaging one in two months over the last several months; 30% — characteristic prostrating attacks occurring on an average once a month over the last several months; 50% — very frequent completely prostrating and prolonged attacks productive of severe economic inadaptability. The regulation does not define "prostrating"; VA applies it to attacks that leave you unable to carry on ordinary activity, typically needing to lie down. The Court of Appeals for Veterans Claims has held that "productive of severe economic inadaptability" means the attacks are capable of causing severe economic hardship, not that you must be unemployed (Pierce v. Principi, 2004). Tension-type and cluster headaches are rated by analogy under the same code.
Step 3: Keep a headache log before and after you file
Record each attack with the date, start and end time, whether you had to stop what you were doing and lie down, what you took, and any work or school missed. Several months of entries let the examiner and rater count attacks "over the last several months" instead of estimating. Ask your treating clinician to note frequency and prostration in your chart, and gather employer records or statements showing absences or accommodations if you are seeking the 50% level.

Step 4: File the claim
On VA Form 21-526EZ list "migraine headaches" (adding "secondary to service-connected [condition]" where that is the route) and attach the diagnosis, treatment records, headache log, any nexus opinion and lay statements. File online, by mail to the Claims Intake Center (PO Box 4444, Janesville, WI 53547-4444), in person or through a free accredited representative. If VA denied headaches before, a Supplemental Claim (VA Form 20-0995) with new and relevant evidence — a nexus opinion or a log — reopens it.

Step 5: The claim exam and the decision
The headaches exam uses VA's Headaches (Including Migraine Headaches) questionnaire, which records the diagnosis, symptoms, duration, whether attacks are prostrating, their frequency, and the effect on work. Bring the log and describe a typical attack and a bad one. The rating decision will state which level the evidence supports; if attacks become more frequent later, file for an increase with updated records. Medication side effects and overuse headaches should be in the record too, since they bear on frequency and function.
Critical tips
- A migraine rating combines with other ratings under 38 CFR 4.25; a 50% migraine rating with other service-connected conditions can support individual unemployability under 4.16 when the headaches prevent substantially gainful work.
- Migraine with aura, menstrual migraine and chronic migraine are all rated under DC 8100 on the same frequency criteria.
- Post-traumatic headache after a service-connected TBI can be rated separately from the TBI residuals when it is a distinct diagnosis; VA cannot rate the same symptom twice (4.14).
