Veterans routinely under-claim because they don't know a secondary condition exists. These are commonly claimed as secondary to service-connected Traumatic Brain Injury (TBI), each is a candidate to raise with your provider, not an automatic grant, and each needs a medical nexus opinion.
Migraine / tension headaches
Post-traumatic headaches/migraines are a recognized residual of a service-connected traumatic brain injury; claim with a nexus opinion tying them to the TBI.
Evidence the VA looks for
A strong Traumatic Brain Injury (TBI) claim ties a current diagnosis to your service with a medical nexus. The records that move a Traumatic Brain Injury (TBI) claim, in priority order:
- Documentation of the in-service head-injury event (incident report, blast/IED exposure, deployment records, or a buddy statement)
- A current diagnosis of TBI residuals from a qualified clinician
- An evaluation of cognitive impairment across the ten facets the VA uses (memory, attention, judgment, social interaction, etc.) — the highest facet level sets the rating
- Records of emotional/behavioral and physical residuals (any distinct diagnosable condition is rated separately under its own code)
- A nexus opinion linking the residuals to the in-service event
The Compensation & Pension exam. A VA-arranged medical exam used to evaluate your claimed condition and how severe it is. Showing up and describing your worst days matters. exam and the The medical link between an injury or event during your service and your current diagnosed condition. A nexus opinion is written and signed by a licensed clinician, not by you or this app.
For most Traumatic Brain Injury (TBI) claims the VA schedules a Compensation & Pension (C&P) exam. The examiner measures the things the rating schedule turns on and gives a medical opinion on whether your Traumatic Brain Injury (TBI) is at least as likely as not connected to your service (the “nexus”). Knowing what the examiner will assess, and bringing the evidence above, is the single biggest thing you control. Prepare for the exam and check that your records support a nexus before you file.

Traumatic Brain Injury (TBI) VA disability: frequently asked questions
- How does the VA rate TBI residuals?
- Residuals of TBI are rated under 38 CFR 4.124a (Diagnostic Code 8045). Cognitive impairment is evaluated across ten facets, and the single highest facet level sets the rating (0, 10, 40, or 70 percent), with a level of 'total' on any facet rating 100%. The ladder on this page shows each level.
- Are TBI symptoms rated separately?
- Often, yes. Distinct diagnosable conditions that result from a TBI — such as migraines, a mental-health disorder, or a seizure disorder — are rated separately under their own diagnostic codes, in addition to the TBI residual rating, which can raise your combined rating.
- What conditions are secondary to a TBI?
- Post-traumatic headaches and migraines are a recognized residual of a service-connected traumatic brain injury, and a TBI can also contribute to mental-health conditions. Each is separately ratable with a medical nexus opinion linking it to the TBI.
- How is TBI different from PTSD?
- A TBI is a physical injury to the brain, while PTSD is a mental-health condition from a traumatic experience — and they often co-occur after the same event. The VA evaluates them separately and is careful not to rate the same symptom twice; an accurate diagnosis of each is important.
