The rating levels

Criteria paraphrased from 38 CFR § 4.124a, DC 8100 for readability. Monthly amounts are the 2026 rate (effective December 1, 2025) for a veteran with no dependents if this were the only rated condition — dependents add more, and multiple conditions combine under the VA’s own math.

  1. 50%

    $1,132.90/month

    With very frequent completely prostrating and prolonged attacks productive of severe economic inadaptability. The regulation sets no specific weekly count or hour duration for this level.

    Examples from this level’s criteria

    • Very frequent, completely prostrating attacks
    • Prolonged attacks
    • Attacks productive of severe economic inadaptability (document lost work time, reduced productivity or income)
    • Preventive medications not adequately controlling attacks
  2. 30%

    $552.47/month

    Characteristic prostrating attacks occurring on average once a month over the last several months.

    Examples from this level’s criteria

    • At least one prostrating migraine per month
    • Must retreat to dark, quiet room
    • Lost work or activity days monthly
    • Aura (visual disturbances, numbness, speech changes)
  3. 10%

    $180.42/month

    Characteristic prostrating attacks averaging one in two months over the last several months.

    Examples from this level’s criteria

    • At least one severe (prostrating) migraine every two months
    • Prostrating = must stop all activity and lie down
    • Sensitivity to light and sound
    • Nausea or vomiting
  4. 0%

    $0/month (0% is still service-connected)

    With less frequent attacks (fewer than the 10% level's characteristic prostrating attacks averaging one in 2 months over the last several months).

    Examples from this level’s criteria

    • Diagnosed headache disorder
    • Headaches are rare or very mild
    • No lost work days

The listed symptoms are examples that appear in each level’s criteria — not a checklist that earns a percentage. Raters apply the criteria as a whole.

The evidence that matters most

Headache log with dates, duration, and prostrating episodes documented

C&P exam tips for Migraines

  1. 1Keep a headache diary before your exam: date, time, duration, severity (1–10), triggers, medications used, and whether you were incapacitated.
  2. 2The key word is 'prostrating' — it means you must stop all activity and lie down. Use this word explicitly.
  3. 3Describe how each migraine affects your ability to work, drive, or function.
  4. 4Mention any ER visits for migraines.
  5. 5List all medications tried — both preventive and abortive. Showing treatment resistance supports severity.

Common mistakes on Migraines claims

  • Not keeping a headache diary — frequency is the primary rating driver and must be documented.
  • Calling a headache a 'bad headache' instead of documenting that it was prostrating (required you to stop all activity).
  • Not documenting economic impact — lost work time, inability to drive during attacks.
  • Forgetting that the frequency is averaged 'over the last several months,' so you need a track record, not just one bad month.
