Why Most Migraine Ratings Come In Too Low
VA disability claims have gotten complicated with all the conflicting advice flying around. As someone who spent three years fighting the VA over a 10% migraine rating, I learned everything there is to know about this process. Today, I will share it all with you.
The word that changed my entire claim was one I’d never once written in my paperwork: prostrating. That’s it. That single term — buried inside Diagnostic Code 8100 — is what separates a 10% rating from a 50% rating for thousands of veterans. I didn’t know it existed until month nineteen of my appeal.
But what is a prostrating attack? In essence, it’s an attack that forces you to stop everything and lie down. Not sit. Not take a break with a glass of water. Lie down. But it’s much more than that — the VA isn’t evaluating your pain level. It’s evaluating whether your migraines destroy your ability to work, parent, and function on a basic daily schedule. That distinction costs veterans thousands in benefits every single year.
Probably should have opened with this section, honestly. When I finally pulled my rating decision — around month eight — the examiner had written: “Veteran reports occasional headaches managed with over-the-counter medication.” I never used the word occasional. I never mentioned over-the-counter anything. That language came from how I described my symptoms: vague, minimizing, almost apologetic. Don’t make my mistake.
The VA doesn’t rate suffering. It rates documented frequency and impact. Your evidence file is everything. The C&P exam is just one piece of a much larger puzzle.
The Rating Breakdown and What Each Level Requires
Migraine ratings land at 0%, 10%, 30%, or 50%. Each threshold has specific evidence requirements — and understanding what separates them is how you build an actual claim strategy instead of just hoping the examiner is having a good day.
0% Service Connection
You have a diagnosis. There’s a link to service. But the condition causes no real functional impairment, or symptoms are minimal enough that no ongoing treatment exists. Rare for migraines that survived the service connection phase, but it does happen when documentation is genuinely thin.
10% — The Default Rating
This is where most claims land — and where most stay. The VA sees a migraine diagnosis, maybe some treatment records, and not much else. No clear pattern of prostrating attacks. No frequency count. No evidence of work disruption. The examiner defaults to 10% and closes the file. That’s what makes this rating so frustrating to those of us who’ve been there — it feels like the floor, not a real assessment.
Moving past 10% requires three things: proof of frequency, evidence of prostration, and documentation of economic impact. All three. Not one, not two.
30% — The Frequency Threshold
At 30%, the VA wants to see characteristic prostrating attacks happening more than once a month — meaning multiple attacks monthly, not a single bad one. Medical records should reflect ongoing treatment: preventative medications, ER visits, specialist notes. A consistent migraine log showing dates and severity matters here. So do buddy statements from people who’ve actually watched you suffer through an attack.
The jump from 10% to 30% is almost always an evidence-quality problem. Veterans move up when they show a documented pattern — not isolated incidents scattered across years of sparse records.
50% — Economic Inadaptability
This is the rating that changes the math entirely. At 50%, the VA concludes the veteran cannot sustain competitive employment due to migraine frequency and severity. Economic inadaptability isn’t a feeling — it’s a set of concrete facts: documented work absences, employer-approved reduced hours, performance reviews citing headaches, an actual termination letter, or demonstrated inability to maintain any consistent schedule.
I know a veteran who hit 50% by submitting three documents: his termination letter from a trucking company, a letter from his neurologist at the Minneapolis VA explaining treatment required during work hours, and a three-month log showing 18 prostrating attacks. That was it. Those three documents built a case the VA couldn’t deny.
Getting to 50% requires connecting clinical frequency to real-world impact on earning capacity. It’s not a guess. It’s a documented argument.
How to Document Prostrating Attacks the Right Way
Documentation is where migraine claims either succeed or stall permanently. So, without further ado, let’s dive in.
Start a migraine log today. A $3 spiral notebook works. So does a Google Sheet or an app — Migraine Buddy and Headache Diary are both solid choices with export features that make VA submissions cleaner. Record four things for every attack: date, duration in hours, severity on a 0–10 scale, and — most importantly — what you had to stop doing. Write “left work at noon,” “laid down for six hours,” “missed my daughter’s soccer game at Jefferson Middle School,” “couldn’t drive,” “vomited twice before the pain peaked.”
The examiner reading your file has never felt your migraine. The log tells them what it costs you. An entry like “May 14, 3 PM onset, 8/10 severity, laid down for four hours, missed evening shift at work” is gold. An entry that says “bad headache” is worthless.
Keep the log for at least three to six months before filing or refiling. Two weeks of entries won’t establish a frequency pattern. Six months of consistent data shows the VA you’re tracking real, ongoing disability — not building a case around one rough week.
Get a buddy statement. A spouse, a coworker, a neighbor who’s seen you during an attack — any of them will do. Have them write a simple letter describing what they’ve personally witnessed: how many attacks, what the symptoms look like from the outside, what you do during an episode, and how it disrupts daily life. They don’t need medical credentials. They just need to say things like “I’ve seen my husband unable to get out of bed for hours” or “She goes to the ER at least once a month.” That letter enters your evidence file and establishes frequency from a credible outside source.
Pull your private medical records — all of them. Neurologist files, primary care notes, urgent care visits, ER trips. ER records are especially valuable because they document severity requiring emergency intervention. Prescription records for triptans like sumatriptan 100mg, preventatives like topiramate or propranolol, or anti-nausea medications like ondansetron all demonstrate treatment intensity. Even insurance refill records can help establish frequency.
Don’t minimize during medical appointments. I’m apparently someone who downplays symptoms in civilian doctor visits — always worried about seeming dramatic — and that habit destroyed months of my claim. Those records showed up in my VA file with phrases like “veteran manages symptoms well at home.” That hurt me directly. Now I tell every doctor the full picture: attacks per month, what I can’t do during them, every treatment I’ve tried and failed.
A nexus letter from a private doctor might be the best option, as a strong migraine claim requires a clear medical link to service. That is because the VA gives significant weight to signed clinical opinions from treating physicians who know your case — not just checkbox forms from examiners who met you once.
Connecting Migraines to a Service-Connected Condition
Filing migraines as secondary to another service-connected condition is a strategic opening many veterans completely miss. It increases your combined rating and gives the VA a cleaner path to approving higher percentages. That’s what makes secondary connections so endearing to us veterans navigating a system that rarely gives anything away easily.
The most common secondary connections are:
- Traumatic Brain Injury (TBI). Post-concussive headaches and migraines are well-established TBI consequences. If you already carry a TBI rating, filing migraines as secondary has strong precedent. VA case law backs the nexus.
- Cervical Spine Injury. Nerve compression, arthritis, or muscle tension from neck injuries frequently trigger migraines. Records showing cervical pathology alongside migraine symptoms create a straightforward secondary claim.
- PTSD or Sleep Disorders. Sleep disruption from PTSD can set off migraines. Anxiety heightens attack frequency. Less obvious connections — but fully documentable with a solid nexus letter from the right physician.
- Tinnitus or Hearing Loss. Some migraines carry a vestibular component. Rarer, but worth exploring if you already carry hearing or balance conditions in your file.
A secondary service connection requires two things: an existing service-connected condition and a medical nexus connecting it to your migraines. The nexus letter is your tool. Ask your VA neurologist, private neurologist, or primary care doctor to write a statement along these lines: “Based on my examination of the veteran and review of the service medical records, it is more likely than not that the veteran’s migraines are related to the cervical spine injury documented in the service record.”
The letter doesn’t need to be long. It needs to be clear, specific, and signed by a licensed physician. Some private doctors charge $200 to $400 for a nexus letter — some provide them free if you’re already an established patient. Either way, it’s one of the best investments you can make in a migraine claim. I wish someone had told me that in year one.
What to Do If Your Migraine Rating Got Denied or Underrated
Three main options exist: a Higher-Level Review, a Supplemental Claim, or a Board Appeal. Each has a different timeline and a different strategic purpose.
A Higher-Level Review is fast but limited. A senior rater reviews your existing file — no new evidence allowed. Use this only when you believe the original examiner misread evidence that was already sitting in your file. Clear factual error, not a missing document.
A Supplemental Claim is my recommendation when you have new evidence to add. A migraine log you didn’t have before. A new medical opinion. Updated ER records from the past six months. A buddy statement. File VA Form 20-0995 and submit everything together. The VA reassesses based on the expanded file. Many Supplemental Claims move faster than initial claims — though timelines vary widely by regional office.
A Board Appeal takes longer — first, you should expect six to twelve months minimum, at least if you want a thorough written decision. You request a hearing before a Veterans Law Judge, present your evidence, and receive a ruling that sets legal precedent inside your file. Use this when your documentation is solid and you’re prepared to wait for a decision that actually sticks.
Before filing anything, pull your rating decision. Read the reasoning section word by word. The VA explains exactly why you received the percentage you got — and that explanation tells you precisely what evidence you need to counter it. If the decision reads “no pattern of prostrating attacks,” your next submission centers on the log you’ve been keeping for six months. If it says “no work impact,” you include employer documentation, absence records, or performance reviews. The C&P exam is not the finish line. Your evidence file drives the rating. That mindset shift — honestly — is what changes outcomes.
