What Is Migraines
Migraines are recurring severe headaches that the VA rates under Diagnostic Code 8100 on a scale of 0%, 10%, 30%, or 50% depending on how often you have "prostrating attacks" (episodes so severe they incapacitate you and force you to bed or lie down).
VA Rating Criteria
The VA doesn't rate migraines by pain level alone. Your rating depends entirely on attack frequency and whether those attacks prostrate you:
- 0%: Diagnosis of migraines without prostrating attacks, or attacks so infrequent they don't significantly impact your function.
- 10%: Occasional prostrating attacks (typically fewer than one per month on average).
- 30%: Frequent prostrating attacks (roughly one or more per week, or multiple times monthly with documented patterns).
- 50%: Very frequent prostrating attacks (multiple times per week, or near-daily severe episodes). This is the highest rating for migraines under the current rating schedule.
What the VA Requires in C&P Exams
During your Compensation and Pension (C&P) exam, the VA examiner will document the frequency, duration, and disabling nature of your migraine attacks. They need specifics: How many attacks per month? How long do they last? What forces you to stop activity? Do you vomit, experience visual disturbances, or lose consciousness?
Your private medical records matter here. A decades-long history of migraine treatment, emergency room visits, or hospital admissions strengthens your claim. If your records show gaps, the VA will likely rate you conservatively.
Nexus Letters and Service Connection
If your migraines began or worsened during military service, you need to establish service connection. A nexus letter from a neurologist or your primary care physician linking your current migraines to a specific service incident, exposure, or condition is critical. Common service connections include traumatic brain injury (TBI), combat stress, noise exposure, or chemical exposure.
The nexus letter should state whether it's at least "as likely as not" that service caused or aggravated your migraines. Without this, the VA will deny your claim outright, even if your migraines are severe.
Appeals and Working With a VSO
If the VA rates you 0% or 10% but you believe your attacks are more frequent, file a VA Form 21-0996 (Decision Review Request) within one year. Prepare a detailed timeline of attacks for the past 12 months, including dates, severity, and impact on work or daily activities.
A VA-accredited Veterans Service Officer (VSO) can request your C&P exam notes and spot weaknesses in the examiner's documentation. If the examiner notes only three attacks when your medical records show monthly patterns, that's an error worth appealing. VSO representation is free and can mean the difference between a 10% and 30% rating.
Connection to Traumatic Brain Injury
Many veterans with service-connected TBI develop secondary migraines. If you have both, list both conditions on your claim. Secondary migraines can increase your overall combined rating, and establishing this relationship in your nexus letter helps both claims.
Common Questions
- Does the VA consider chronic daily headaches that aren't full migraines? No. Under Diagnostic Code 8100, the rating requires migraines with prostrating attacks. Chronic tension headaches or mild daily pain won't qualify. You may need a neurologist to confirm the diagnosis is actually migraines, not another condition.
- Can I get a higher rating than 50%? No. 50% is the maximum for migraines alone. If your combined rating for migraines plus other conditions puts you at 60% or higher overall, you might qualify for individual unemployability, but that's a separate process.
- What if I'm not having attacks during my C&P exam? The examiner rates you based on your typical pattern, not whether you have an attack during the appointment. Bring a detailed personal diary or calendar showing attack frequency over the past year. Medical records, including ER visits or urgent care notes, are your strongest proof.
