1. What This Condition Is
Migraine headaches are a neurological condition, not just bad headaches. They cause debilitating head pain, often on one side, combined with nausea, vomiting, sensitivity to light and sound, and sometimes visual disturbances called auras. A true migraine attack can put you flat on the couch for hours or days. Veterans get migraines from traumatic brain injuries, blast exposure, PTSD-related stress, disrupted sleep, and chronic neck or cervical spine injuries sustained during service. The VA rates this condition because frequent, severe migraines directly reduce your ability to hold a job and function day to day.
2. VA Rating Criteria
Migraine headaches are rated under 38 CFR § 4.124a, Diagnostic Code 8100. The rating depends entirely on how often prostrating attacks occur and how severely they affect your ability to function.
"Prostrating" means the attack causes extreme exhaustion or incapacitation with substantial inability to engage in ordinary activities. "Completely prostrating" means essentially total inability to function.
| Rating | Criteria |
|---|---|
| 50% | Very frequent, completely prostrating and prolonged attacks productive of severe economic inadaptability |
| 30% | Characteristic prostrating attacks occurring on average once a month over the last several months |
| 10% | Characteristic prostrating attacks averaging one in 2 months over the last several months |
| 0% | Less frequent attacks |
The 50% rating is the maximum under DC 8100. However, if your migraines cause total occupational impairment, you may qualify for Total Disability based on Individual Unemployability (TDIU) even at a combined 60% or 70% rating with migraines as a significant contributing factor. See 38 CFR § 4.16.
Document both the frequency and the functional impact of each episode. The VA evaluates which rating level your symptom picture most closely approximates and assigns that rating directly.
3. What to Expect at Your C&P Exam
The examiner will ask how many migraine attacks you have per month and how long each one lasts. They will ask what you cannot do during an attack: can you drive, work, care for your children, tolerate light or noise? They will ask whether you go to a dark, quiet room and stay there. They will ask about nausea, vomiting, and aura symptoms.
The examiner will also ask about your medications and whether they work. Partial relief does not disqualify you. They will review your treatment history and ask what triggers your migraines. Expect questions about missed work, reduced hours, or job accommodations you have needed.
The key measurement is functional loss during attacks, not just pain level. Bring a written summary of your worst attacks and what you were unable to do during them.
4. Evidence You Need to Win
Diagnosis: A medical diagnosis of migraine headache disorder from a physician, neurologist, or VA provider. Self-reporting alone is not enough.
Nexus Letter: A nexus letter connects your migraines to your military service. Your private physician or a VA-accredited examiner needs to state that your migraines are at least as likely as not caused by or aggravated by your in-service event (blast exposure, concussion, chronic stress, cervical injury). Cite 38 CFR § 3.303 for direct service connection or 38 CFR § 3.310 if filing migraines secondary to a service-connected condition like TBI or PTSD.
Headache Diary: This is your most powerful personal evidence. Log every migraine: date, time, duration, severity, what you could not do, what medications you took, whether you vomited or could not tolerate light or noise. A three-to-six month log showing consistent frequency is what separates a 10% claim from a 30% or 50% claim.
DBQ Form: VA Form 21-0960N-3 (Headaches, including Migraine Headaches DBQ). Get this completed by your treating physician if you can. The DBQ asks directly about prostrating episodes and frequency, so a thorough answer from a treating doctor carries real weight.
Buddy Statements: Have a spouse, roommate, coworker, or supervisor complete VA Form 21-10210 (Lay/Witness Statement) or submit a written statement describing what they observe during your attacks. Statements that say "I have seen him unable to get out of bed for two days, vomiting, with all the curtains drawn" give the rater concrete, specific evidence.
Employment Records: If you have missed work, requested accommodations, or had performance issues tied to migraines, document that with employer letters or your own written statement.
5. Secondary Conditions to Consider
Traumatic Brain Injury (TBI): Blast-exposure migraines are a hallmark TBI residual. If you have a TBI claim, file migraines as a secondary condition under 38 CFR § 3.310. The two are frequently connected.
PTSD: Chronic stress and hypervigilance are established migraine triggers. If your PTSD predates your migraines or you can show the connection, file migraines secondary to PTSD.
Sleep Apnea: Disrupted sleep is a direct migraine trigger. Veterans with both conditions should document the connection and file sleep apnea as either a separate primary claim or linked secondary condition.
Depression and Anxiety: Chronic pain conditions, including frequent migraines, are well-documented contributors to depression and anxiety disorders. File these separately under 38 CFR § 3.310 with a nexus letter establishing the connection.
Cervical Strain (Neck): Cervical musculature tension is a known migraine trigger. If you have a service-connected neck condition, explore filing migraines secondary to cervical strain.
Tinnitus: Both tinnitus and migraines often follow blast exposure. If you have not yet filed tinnitus, do so at the same time.
6. Common Mistakes That Kill Claims
Not keeping a headache diary. The rater cannot see inside your head. Frequency on paper wins the rating. Frequency in memory does not. Start logging today, even if your exam is months away.
Describing pain without describing function. "My head hurts really bad" is not the same as "I was unable to drive, cook, or speak to my children for 36 hours." Tell the VA what you cannot do, not just how much it hurts.
Only counting the worst attacks. Veterans often discount moderate migraine days. If you spent a workday in a dark room at 60% capacity, that counts. Log it.
Forgetting to establish the in-service event. The VA needs a starting point: the IED blast, the training accident, the MVC, the chronic stress. Pull your service treatment records (STRs) and identify any documentation of head trauma, concussion, headache complaints, or cervical injury.
Accepting 0% or 10% without appealing. If your actual frequency is higher than what the rating reflects, request a higher-level review or file a supplemental claim with your headache diary. The VA frequently underrates migraines on initial decisions.
7. FWD Assist Resources
If your migraines followed a head injury or blast exposure, the FWD Assist TBI Guide walks you through filing TBI and its residuals together. The FWD Assist C&P Exam Prep Guide has a specific section on neurological exams and what examiners measure during headache evaluations. The FWD Assist Nexus Letter Toolkit shows you exactly how to brief a private physician so the letter addresses prostration frequency, functional loss, and the in-service nexus. If your migraines are contributing to your inability to work, the FWD Assist TDIU Guide covers the 38 CFR § 4.16 pathway in plain language.

8. Get Help Without a Claim Shark
Free help is available through Veterans Service Organizations (VSOs) like the DAV, VFW, and American Legion. Your county likely has a County Veterans Service Officer (CVSO) who can file and manage your claim at no cost. VA-accredited claims agents and attorneys can also represent you.
Anyone who charges you upfront fees before an initial VA decision is breaking federal law under 38 USC § 5905. Accredited attorneys and agents are only permitted to charge a fee after an initial VA decision has been issued, and that fee is capped at 20% of past-due benefits. Never pay upfront for claims help.
