VA Rating for Migraines: How It Works

By the VetClaimsGuide Editorial Team · Educational guide · Updated June 2026

Migraine claims often come down to one word and one habit: the word is "prostrating," and the habit is keeping a headache log. Here is how VA rates migraines and how to document them so your rating reflects reality.

Before you file, appeal, or request an increase: use the free Claim Readiness Checker to identify possible evidence gaps. It is an educational starting point, not claim filing or representation.

How VA rates migraines

Migraines are rated under Diagnostic Code 8100, based on how often you have prostrating attacks:

What "prostrating" means

This is the word VA hangs everything on. A prostrating attack is one so severe that you have to stop what you are doing and lie down. A headache you push through is not prostrating in VA's eyes. So your evidence should make clear, in plain terms, that your attacks force you to stop normal activity, and how often that happens.

Your key evidence: a headache log

Because migraines do not show up on a scan, the single most persuasive piece of evidence is a headache log. For each attack, record the date, how long it lasted, how severe it was, and what it forced you to stop doing (leave work, lie down in a dark room, miss an event). A few months of this log, paired with a diagnosis and a nexus, is what moves a migraine rating. Estimate where you might land with the free VA Rating Estimator (migraines are built in).

Migraines as a secondary condition

Migraines are frequently claimed as secondary to other service-connected conditions, such as a traumatic brain injury (TBI), a neck condition, or PTSD. If a primary condition is driving your headaches, a medical opinion connecting them can open the door. Explore the link with the Secondary Conditions Mapper and bring your doctor an educational Nexus Letter Template.

Get organized: use the free Evidence Builder to organize records, statements, and questions to discuss with an accredited representative or provider. You can email yourself your results so you can come back later and keep preparing.

Frequently asked questions

How does VA rate migraines?
Migraines are rated under Diagnostic Code 8100 at 0, 10, 30, or 50 percent, based on how often you have prostrating attacks. 50 percent is the maximum and requires very frequent, prolonged, completely prostrating attacks that cause severe economic inadaptability.
What does prostrating mean for VA migraines?
A prostrating attack is one severe enough that you have to stop what you are doing and lie down. It is the key word VA looks for, so your evidence should describe attacks that force you to stop normal activity.
What is the key evidence for a migraine claim?
A headache log recording the date, duration, severity, and what each attack forced you to stop doing. Combined with a diagnosis and a nexus, it is the single most persuasive piece of evidence because migraines are otherwise hard to measure.
Can migraines be claimed as secondary?
Yes. Migraines are often claimed secondary to conditions such as a traumatic brain injury, a neck condition, or PTSD, supported by a medical opinion linking them.
