Secondary Condition Claim · VASRD 8100
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 Post-Traumatic Stress Disorder (PTSD).
Often triggered by PTSD stress
Primary condition · VASRD 9411
Post-Traumatic Stress Disorder (PTSD)
PTSD is a mental health issue caused by a traumatic event, leading to flashbacks, anxiety, or nightmares.
Secondary condition · VASRD 8100
Migraine
Severe recurring headaches that may include nausea, light sensitivity, and inability to function.
The VA rates Migraine the same way whether it's claimed directly or as secondary to Post-Traumatic Stress Disorder (PTSD) — severity of Migraine itself determines the percentage.
Example combined rating
70% Post-Traumatic Stress Disorder (PTSD) + 30% Migraine = 79%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 70% and 30% combine to 79%, not 100%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
