Migraines C&P Exam: What Examiners Look For

The compensation and pension exam is often the single event that determines your migraine rating. Walking in without preparation is one of the most costly mistakes a veteran can make. Here's what actually happens in the room.

The Purpose of the C&P Exam

A C&P examiner's job is to answer specific questions for the rating board. For migraines, those questions center on two things: the nexus (is the condition service-connected?) and the severity (what rating does the frequency and impact warrant?). The examiner is not your treating physician. They're not there to diagnose or treat you. Their report goes directly to the rater who assigns your percentage.

Understanding this dynamic changes how you should communicate. Your goal is to give complete, accurate, specific information, not to minimize or perform wellness.

The Questionnaire and Interview

Most C&P exams for migraines follow a structured questionnaire called a Disability Benefits Questionnaire (DBQ). The examiner will either fill it out during your interview or complete it afterward. The headache DBQ covers:

• Headache diagnosis: Are these classified as migraine, tension-type, cluster, or other?
• Frequency: How many headaches per month total, and how many qualify as prostrating?
• Duration: How long does a typical attack last?
• Severity: Pain level, associated symptoms (nausea, vomiting, light sensitivity, sound sensitivity, visual aura)
• Functional impact: What activities do you have to stop or avoid during attacks?
• Medications: What are you currently taking, and does it control the attacks?
• Nexus opinion: Is the condition related to the in-service event (direct, secondary, or aggravation)?

What "Prostrating" Looks Like in the Exam Room

The examiner needs to determine whether your attacks are "prostrating" as defined by the rating schedule under Diagnostic Code 8100. They will ask you to describe what happens during a bad headache.

Be specific. Don't say "I feel pretty bad." Say:

• "I have to stop whatever I'm doing and go lie down in a dark room."
• "I can't drive, read, or look at screens during an attack."
• "I often vomit. The pain is 8-9 out of 10 at its worst."
• "I miss work an average of one to two days per month because of migraines."
• "I had to leave my daughter's soccer game early last month because the light and noise triggered one."

Concrete examples are more credible than general statements. The examiner writes what you tell them, and the rater reads what the examiner writes.

The Frequency Question

Frequency is the linchpin of the migraine rating. The examiner will ask how often you get prostrating attacks. Your answer needs to be consistent with your headache diary and your treatment records.

If you say "once a month" but your VA medical records show no migraine-related visits in the past year and you've had no prescription refills, there's a credibility gap. Your records and your testimony should tell the same story. This is one of the strongest reasons to document migraine frequency before your exam.

Nexus Questions at the C&P Exam

If you're filing for direct service connection, the examiner will ask about the in-service event that you believe caused or contributed to your migraines. Be prepared to:

• Describe the specific event (blast, head trauma, toxic exposure)
• State when headaches began relative to that event
• Describe how they've progressed since separation

If you're filing for secondary service connection (for example, migraines secondary to PTSD or TBI), the examiner will note your primary service-connected condition and assess whether the biological connection is plausible. Having a nexus letter already in your file before the exam is one of the best things you can do. Examiners are more likely to agree with a well-documented physician opinion than to author one independently.

Common C&P Exam Mistakes for Migraines

These patterns consistently lead to lower ratings or denials:

• Being stoic. Veterans often understate their worst days and describe average ones. Describe the full range.
• Forgetting associated symptoms. Nausea, vomiting, light and sound sensitivity, and visual aura all matter. If you have them, say so.
• Not mentioning impact on work and family. The rater needs to see how migraines limit your life, not just how bad your head hurts.
• Arriving without documentation. Bring your headache diary. Bring any private treatment records not yet in your file.
• Describing controlled attacks when they're not fully controlled. If medication reduces severity but doesn't eliminate attacks, that's important information.

After the Exam

Request a copy of the C&P examiner's DBQ report. If the opinion is inadequate, cursory, or factually wrong, you can challenge it. A favorable nexus letter from an independent physician can rebut a negative C&P opinion. The VA must consider both.
