Migraine VA ratings: how the VA rates migraines, explained by a neurologist

Migraine can be service connected and rated by the VA from 0% to 50%. This guide explains how the VA rates migraines, what the rating criteria mean, how to document your attacks and how a neurologist’s medical opinion can support your claim. It is general information, not legal advice.

How does the VA rate migraines?

The VA rates migraines under diagnostic code 8100 of its rating schedule (38 CFR § 4.124a). The criteria are:

In November 2024, the VA proposed revising the neurological section of its rating schedule, which includes migraine. Until a final rule takes effect, the criteria above are the regulation in force. The federal regulatory agenda projects the final rule for April 2027, an estimate that can change.

What is a prostrating migraine attack?

The rating schedule does not define “prostrating.” It is generally understood as an attack so severe that you have to stop what you are doing and lie down or rest until it passes. For the rating, what matters is how often your attacks reach that level, not only how often you have a headache.

The 50% rating also requires attacks “productive of severe economic inadaptability.” The Court of Appeals for Veterans Claims has held that this does not require you to be completely unable to work, and that the attacks only need to be capable of producing severe economic inadaptability (Pierce v. Principi, 18 Vet. App. 440 (2004)).

How do you document migraine attacks for a VA claim?

• A headache diary: the date and length of each attack, your symptoms, whether you had to stop and rest, the medicines you took and any time missed from work
• Treatment records: visits, the diagnosis, medicines you have tried and procedures such as Botox injections or nerve blocks
• Statements from people who see your attacks, such as family members or coworkers
• Work records that show missed days or changes in your duties, if you have them

How is migraine connected to military service?

Migraine can be service connected directly, when it began or was caused during service, or as a secondary condition caused or worsened by another service-connected condition, such as a traumatic brain injury. Whether a link exists depends on your medical history and the evidence, and a medical opinion is often needed to explain it.

How can a neurologist’s nexus letter help?

A neurologist can review your service and medical records, confirm the diagnosis, describe how often and how severely your attacks occur, and explain the medical reasoning on whether your migraine is at least as likely as not connected to service. The VA weighs medical opinions by the writer’s expertise, the records reviewed and the reasoning.

At Integrated Neurology & Pain Management (INPM), Dr. Amar Anand, a board-certified neurologist whose clinical interests include headache and migraine, prepares VA nexus letters for veterans in California and across the United States. A letter is provided only when the medical evidence supports it. Fees begin at $1,500, and the first 15-minute consultation is free. Learn more about VA nexus letters.

If you live in the Bay Area and need migraine care, INPM also treats migraine in Walnut Creek and Vallejo, with in-office options such as Botox for chronic migraine and nerve blocks. See migraine and headache care.
