Migraine Secondary to Ankylosis of the Cervical Spine
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Migraine when it develops after Ankylosis of the Cervical Spine.
Why Migraine Is Linked to Ankylosis of the Cervical Spine
Restricted movement
Primary condition · VASRD 7203

Severe stiffness or immobility of the neck due to spinal fusion or disease.
Secondary condition · VASRD 8100
Migraine
Severe recurring headaches that may include nausea, light sensitivity, and inability to function.
Migraine VA Rating Tiers
The VA rates Migraine the same way whether it's claimed directly or as secondary to Ankylosis of the Cervical Spine — severity of Migraine itself determines the percentage.
Example combined rating
35% Ankylosis of the Cervical Spine + 30% Migraine = 55%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 35% and 30% combine to 55%, not 65%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
Evidence for a Migraine Secondary Claim
- •Neurology consult with detailed migraine history
- •Headache diary showing frequency and impact
