TL;DR
- VA rates migraine headaches under Diagnostic Code 8100, where the jump from 0% to 10%, 30%, or 50% usually turns on whether the record proves prostrating attacks over the last several months.
- A strong migraine log tracks at least 8 core fields: date, start and stop time, symptoms, whether you had to lie down, medication, trigger pattern, missed work, and next-day functional impact.
- A practical 90-day log is not magic by itself, but it gives raters and clinicians a clean timeline that can line up with treatment notes, a Headaches DBQ, buddy statements, and employer records.
- TYFYS is not the VA, not a VSO, and not a law firm. We do not file claims or give legal advice. We help veterans organize stronger private medical evidence before they file through VA.gov or with an accredited representative.
A VA migraine claim can look obvious to the veteran and still stall at 0% or 10% because the file never shows a clean pattern. The rating schedule does not pay for the word “migraine” by itself. It pays for how often the attacks happen, whether they are prostrating, how long they last, and whether they disrupt work or normal functioning.
The condition is not rare in the veteran population either. VA Whole Health reports that 40% of veterans report chronic headaches, with 10% carrying a migraine diagnosis, 12% a tension-type diagnosis, and 6% both. When that many veterans are dealing with recurring headache patterns, the quality of the documentation becomes the separator between “headaches noted” and a file that actually supports 30% or 50%.
Why a migraine log matters in a VA claim
Diagnostic Code 8100 is built around a recurring pattern over time. The schedule moves from less frequent attacks at 0% to prostrating attacks averaging one in two months at 10%, one per month at 30%, and very frequent completely prostrating and prolonged attacks productive of severe economic inadaptability at 50%.
That is why a log matters. A migraine diary creates a contemporaneous timeline instead of a memory-based estimate given during a 10-minute exam. It also helps your treating records, your DBQ strategy, and your lay evidence all say the same thing.
| Rating | What the schedule is looking for | What your log should help prove |
|---|---|---|
| 0% | Less frequent attacks | Episodes exist, but the timeline does not support a compensable prostrating pattern yet |
| 10% | Characteristic prostrating attacks averaging 1 every 2 months over the last several months | Which attacks forced you to stop activity and lie down |
| 30% | Characteristic prostrating attacks averaging 1 per month over the last several months | A monthly pattern that matches treatment records and functional loss |
| 50% | Very frequent, completely prostrating, prolonged attacks productive of severe economic inadaptability | Attack frequency, attack duration, missed work, reduced reliability, and real occupational impact |
The schedule language is why many veterans use the phrase “migraine log” and “prostrating attacks” in the same breath. The diary is not the rating by itself. It is the proof pattern that supports the rating.
What to track in a strong VA migraine log
The best logs are boring in a good way. They are consistent, specific, and easy for another person to follow. A practical migraine diary entry should capture the same fields every time:
- Date of the attack: the calendar pattern matters
- Start time and stop time: duration becomes critical at the 30% and 50% levels
- Symptoms: headache pain, nausea, vomiting, photophobia, phonophobia, aura, dizziness, or visual changes
- Prostrating yes or no: did you have to stop activity and lie down in a dark or quiet room?
- Medication taken: triptans, rescue medication, OTC medication, injections, or ER treatment
- Trigger pattern: sleep loss, stress spike, light exposure, missed meals, neck flare, sinus flare, or other pattern
- Work or school impact: left early, missed shift, could not drive, lost productivity, or could not finish tasks
- Next-day effect: residual fatigue, brain fog, rebound pain, or additional missed time
VA’s Veterans Health Library also notes that using a headache diary may help identify headache triggers. That same diary becomes useful evidence when it is shared with a treating provider and discussed in the records.
Where TYFYS fits
TYFYS is not the VA, not a VSO, and not a law firm. We do not file claims or give legal advice. We help veterans coordinate private medical evidence so the migraine timeline, the diagnosis, the DBQ findings, and the functional-impact record tell one consistent story before the veteran files through VA.gov or with an accredited representative.
How to build a 90-day migraine log that actually helps
Veterans often ask how far back they should track. There is no official “90-day rule” in Diagnostic Code 8100, but the schedule repeatedly refers to the last several months. In practice, a disciplined 90-day daily log gives you enough time to show whether the attacks are occasional, every other month, monthly, or multiple times per month.
A workable system looks like this:
- Daily entries: even “no migraine today” entries help establish credibility and pattern
- Same format every day: raters and clinicians should be able to scan the timeline fast
- Weekly total: how many total headaches, how many prostrating attacks, how many work disruptions
- Monthly summary: number of attack-days, number of prostrating attacks, total hours down, total work or family disruption
If you are already service connected for tinnitus, PTSD, TBI, neck pain, sinus problems, or sleep disruption, use that same 90-day period to notice what lines up. A strong file is often built on cross-condition consistency, especially when you are also reading the broader migraines and headaches strategy guide or looking at a tinnitus gateway claim.
The evidence stack that should sit behind the log
The migraine log is not supposed to stand alone. A practical evidence package usually includes:
- Current diagnosis and treatment notes: primary care, neurology, urgent care, or private specialist records
- Headaches DBQ support: the current public Headaches DBQ asks directly about frequency, duration, and whether the condition impacts the veteran’s ability to work
- Medication history: rescue meds, preventive meds, dose changes, side effects, and failure of previous therapies
- Buddy statements: spouse, coworker, roommate, or supervisor statements that show what attacks look like in real life; start with the buddy statement guide
- Work-impact proof: missed shifts, reduced hours, leave records, productivity notes, or accommodation history
- Nexus or aggravation evidence: if the migraine theory is secondary rather than direct, the medical link still has to be explained clearly
If you need the records first, start with the Blue Button guide, the private medical records guide, and the service treatment records guide. If you are also trying to understand the combined-rating impact, run the attack scenario through the TYFYS calculator before you file.
The 5 mistakes that sink migraine logs
Mistake 1: only logging the worst attacks
If you only write down the terrible days, the pattern gets distorted and the timeline becomes harder to trust. Daily consistency is stronger than selective memory.
Mistake 2: never saying whether the attack was prostrating
A log that only says “migraine 8/10” does not answer the key rating question. The record needs to show whether you had to stop activity and lie down.
Mistake 3: leaving out work impact
Especially at 50%, a log without missed work, reduced productivity, schedule disruption, or severe functional impact can leave the economic piece too vague.
Mistake 4: keeping the diary private from your treating clinicians
The log becomes stronger when it shows up in treatment notes, medication decisions, or DBQ answers. A private spreadsheet nobody has ever seen is better than nothing, but it is not as strong as a documented clinical pattern.
Mistake 5: using vague labels instead of plain facts
“Bad migraine” is weaker than “had to leave work at 2:10 p.m., lay down in a dark room for 4 hours, vomited twice, and missed my child’s evening event.” Specific facts are what make the file readable.
Who this article is for
This article is for veterans with diagnosed or suspected migraines or recurring headache attacks who need to prove frequency, prostration, and functional loss. It is especially useful for veterans who are filing a new claim, trying to move from 0% to 30% or 50%, or building a secondary theory tied to tinnitus, PTSD, TBI, neck pain, or sinus conditions.
Best next step if this sounds familiar
If you already know your current percentages, start in the calculator. If you need a cleaner evidence plan, begin the TYFYS intake. If you want help figuring out which records or opinions are still missing, book a discovery call.
FAQ
How long should a VA migraine log be?
There is no official minimum in Diagnostic Code 8100, but a clean 90-day log is a practical starting point because the rating language refers to the last several months. The more consistent the tracking, the more useful it becomes.
Does a migraine log have to be on a VA form?
No. Veterans use notebooks, spreadsheets, calendar exports, and app printouts. What matters is consistency, readability, and whether the entries clearly show frequency, duration, symptoms, prostration, and functional impact.
What does “prostrating” usually mean in a migraine claim?
In plain English, it usually means the attack forced you to stop normal activity and lie down or otherwise left you unable to function normally. The more specifically your records and log describe that shutdown, the stronger the file tends to be.
Does TYFYS file the claim with the VA?
No. TYFYS does not file claims, act as a VSO, or provide legal advice. Veterans still file through VA.gov or with an accredited representative. TYFYS focuses on private medical evidence, records organization, and the documentation workflow that can support a stronger file.
Bottom line
A migraine log is not busywork. It is one of the clearest ways to turn a vague headache history into a timeline a rater, examiner, or private clinician can actually use. The veterans who do best usually have a file where the diary, the treatment notes, the medication history, the DBQ language, and the work-impact story all line up.
If your current migraine claim story is scattered across memory, screenshots, and random appointments, use the calculator, review the broader migraine strategy page, and then decide whether you need a stronger evidence package before filing.
