Diagnostic Code 8100 · 38 CFR §4.124a
Migraine headaches are a neurological condition characterized by recurrent episodes of moderate to severe head pain, often accompanied by sensitivity to light and sound, nausea, and visual disturbances. Many veterans develop migraines during or after military service due to head injuries, blast exposure, environmental exposures, or stress. The VA rates migraines under DC 8100 based on the frequency and severity of prostrating attacks and their economic impact. A "prostrating" attack is one severe enough to force the veteran to stop what they are doing and rest or lie down.
| Rating | Criteria |
|---|---|
| 0% | Less frequent attacks than required for a 10% rating. The veteran experiences migraines but they are infrequent and generally not prostrating. |
| 10% | Characteristic prostrating attacks averaging one in two months over the last several months. The veteran has documented episodes of migraines severe enough to be debilitating, occurring roughly every other month. |
| 30% | Characteristic prostrating attacks occurring on an average once a month over the last several months. Monthly debilitating migraines that require the veteran to stop activities and rest. |
| 50% | Very frequent completely prostrating and prolonged attacks productive of severe economic inadaptability. This is the maximum schedular rating. It requires migraines that are not only frequent and completely debilitating but also significantly interfere with the veteran's ability to maintain employment. The Federal Circuit has clarified that "productive of" means "capable of producing" — the veteran does not need to be unemployed, only that the condition is capable of causing severe economic impact. |
Documentation is critical for migraine claims. You need evidence of frequency (how often attacks occur), severity (whether they are prostrating), and duration (how long each episode lasts). A headache diary or log is one of the most effective pieces of evidence — record each migraine episode with the date, duration, symptoms, and what you had to stop doing. Treatment records showing prescriptions for migraine-specific medications (triptans, preventive medications, or injections) demonstrate the medical establishment of the condition. Emergency room visits for severe migraines are particularly strong evidence. If claiming secondary to TBI or another service-connected condition, a nexus opinion is needed.
A prostrating migraine is one severe enough that it forces you to stop your current activity and rest. You are functionally unable to continue working, driving, or performing daily tasks during the attack. The VA does not require you to be bedridden, but the attack must be debilitating enough to significantly impair your ability to function.
The Federal Circuit ruled in Pierce v. Principi that this phrase means the migraines must be "capable of producing" severe economic impact — you do not need to prove actual unemployment. If your migraines cause you to miss work regularly, arrive late, leave early, or significantly reduce your productivity, that can constitute severe economic inadaptability.
Yes, a headache diary is one of the strongest pieces of evidence for a migraine claim. Record the date of each episode, time of onset, duration, severity on a 1-10 scale, accompanying symptoms, and what activities you were unable to perform. This documentation supports the frequency and severity elements of the rating criteria.
Yes. Migraines are commonly claimed as secondary to traumatic brain injury and to PTSD. If you have a service-connected TBI or PTSD and subsequently developed migraines, a medical nexus opinion linking the conditions can support a secondary service connection claim.
