Migraines VA Disability Rating

Diagnostic code 8100
By the editorial deskUpdated Jul 5, 2026Sources verified Jul 5, 2026
Quick summary
Migraines are rated under diagnostic code 8100 from 0 to 50 percent based on the frequency of prostrating attacks and their economic impact.
Key requirements
  • Service connection requires a current diagnosis, an in-service event or exposure, and a medical link (nexus) between the two.
  • VA assigns ratings of 0% to 50% under diagnostic code 8100, using the criteria in the rating table below.
  • The percentage assigned turns on Frequency of prostrating attacks.
  • Measured at the C&P exam: Neurological exam: motor, sensory, reflexes.
VA also uses diagnostic code 8100 for Cervicogenic Headache, Cluster Headaches, Idiopathic Intracranial Hypertension (Pseudotumor Cerebri), Migraine with Aura, Post-Traumatic Headache and Tension-Type Headaches. Those are distinct conditions with their own pages. This page covers Migraines specifically.
This page explains common evidence VA may consider when rating this condition. It is not medical advice and does not diagnose any condition. Talk with a licensed medical professional about diagnosis and treatment, and with a VA accredited representative (38 CFR 14.629) about a specific claim.

Illustrative scenarios showing how the criteria above are applied. These are educational examples, not a prediction of any individual veteran's rating.

About one knock-you-down migraine a month

Illustrates 30%

Situation. A veteran gets migraines that force him to stop what he is doing and lie down in a dark room, averaging about once a month over the past several months.

How the criteria apply. Characteristic prostrating attacks occurring on average once a month line up with the 30 percent level. Prostrating means the attack stops you in your tracks, and the frequency over recent months is what the rater measures.

Very frequent attacks costing work

Illustrates 50%

Situation. A veteran's migraines are very frequent and completely prostrating, to the point his employer has questioned whether he can keep the job.

How the criteria apply. Very frequent completely prostrating and prolonged attacks productive of severe economic inadaptability describe the 50 percent level, which is the top of the schedule for migraines. The link between the attacks and lost work capacity is central at this level.

How this is examined. Peripheral nerve ratings in 38 CFR 4.124a turn on the degree of paralysis of the nerve involved: mild, moderate, moderately severe, or severe incomplete paralysis, or complete paralysis with the specific findings listed for that nerve. The examiner grades this from motor strength, muscle atrophy, reflexes, and sensory testing, often supported by a nerve conduction study or EMG. When the involvement is wholly sensory, the rating is for the mild or at most the moderate degree. A goniometer measures joint motion for the separate spine or joint rating; it does not determine the nerve percentage. Read 38 CFR 4.124a

VA pays attention to whether attacks are prostrating, meaning they stop you from functioning. Severe economic impact matters at the 50 percent level.

What VA looks at

Frequency and severity of prostrating attacks, work impact, treatment history.

Common exam and DBQ topics

Symptoms during attacks, triggers, prescription medications, ER visits, missed work.

Evidence that usually matters

Neurology records, headache diary, work attendance records, lay statements.

Common misunderstandings

Headache frequency is not enough on its own. The attacks must be prostrating and the 50 percent rating requires severe economic impact.

Evidence builder

Migraine evidence checklist

For migraine claims, VA usually needs to understand frequency, duration, severity, whether attacks are prostrating, medication use, and work impact. A migraine log explains the pattern far better than a general statement like 'I get headaches.'

  • Diagnosis or treatment history for migraines, VA or private
  • A migraine log: dates, duration, and what each attack forced you to stop doing
  • How many prostrating attacks per month (prostrating means you must stop and lie down)
  • Typical duration of an attack, from onset to functional again
  • Light or sound sensitivity, aura, nausea, or vomiting during attacks
See and print the full checklist (11 items)

Small rules in the regulations decide a surprising number of claims. These are the ones that most often change a migraines outcome. None of this is legal advice; it is a map of where to look.

Specific to migraines
  • The word that decides this is prostrating, attacks bad enough to force you to stop and lie down. The 50 percent level needs very frequent, completely prostrating attacks that badly hurt your ability to work.

    WhyMigraines are rated on how often you have prostrating attacks, the kind that force you to stop and lie down. The 50% level needs very frequent, completely prostrating, and prolonged attacks that cause severe economic inadaptability. Make sure the record shows attacks that stop you, not just headaches.

  • The schedule stops at 50 percent. If migraines hurt your work beyond that, the path is an extraschedular referral, not a higher number.

    WhyDiagnostic Code 8100 stops at 50%. If migraines interfere with work beyond what 50% captures, the path is an extraschedular referral, not a higher schedular number.

  • A headache diary is your strongest evidence, since VA decides this on frequency and severity. Log your attacks, ER visits, and missed work.

    WhyVA decides the rating on frequency and severity, so a contemporaneous diary of your attacks, plus any ER visits or missed work, carries real weight at the exam and on review.

Proof and evidence
  • What you and people around you witnessed is real evidence

    You do not always need a doctor to prove a symptom you can see, hear, or feel. Statements from you, family, or fellow service members about things like pain, ringing in the ears, or panic attacks are competent lay evidence under 38 CFR 3.159. A clear buddy statement with dates and specifics can carry weight.

    38 CFR 3.159
  • A tie goes to you

    When the evidence for and against a point is roughly equal, VA is required to decide in the veteran's favor. This benefit of the doubt rule lives in 38 CFR 3.102. You do not have to prove a claim beyond all doubt, only to bring the evidence to about even.

    38 CFR 3.102
  • An unbroken line of symptoms can stand in for a paper trail

    For certain chronic conditions, showing symptoms that continued from service to now can help establish service connection even without a perfect record. This continuity of symptomatology idea comes from 38 CFR 3.303(b) and applies to the chronic diseases the regulation lists.

    38 CFR 3.303
  • If it happened in combat, your word can be enough that the event occurred

    For anyone who served in combat, VA must accept your own account of what happened during that combat as proof the event took place, as long as it fits the conditions of your service, even when no record survives. This comes from 38 U.S.C. 1154(b). It does not by itself prove the injury, but it can establish the in service event.

    38 U.S.C. 1154(b)
  • If it was not written down at entry, you are presumed to have entered healthy

    Unless a condition was noted on your entrance exam, the law presumes you were sound when you entered service. To rebut that, VA has to show by clear and unmistakable evidence both that the condition existed before service and that service did not make it worse. See 38 CFR 3.304(b).

    38 CFR 3.304
  • You can reopen a denied claim with new and relevant evidence and keep your date

    After a decision, a Supplemental Claim lets you add new and relevant evidence. If you file it within one year of the decision, you protect your original effective date, so back pay can reach further. See 38 CFR 3.2501.

    38 CFR 3.2501
  • Some conditions are presumed if they show up within a year of getting out

    Certain chronic diseases, including hypertension, arthritis, and diabetes, that appear to a compensable degree within one year of leaving service are presumed connected to service, even without proof of a specific cause. See 38 CFR 3.307 and the list in 3.309.

    38 CFR 3.309
  • A diagnosis years later can still be service connected

    A condition first diagnosed long after you left service can still be service connected if the evidence ties it back to something in service. You do not need a diagnosis while still in uniform. See 38 CFR 3.303(d).

    38 CFR 3.303
Rating math
  • The same symptom is rated once, but separate problems are rated separately

    VA cannot rate the same symptom twice, which is pyramiding under 38 CFR 4.14, but it can and should rate distinct problems on their own. A scar and the loss of motion under it, for example, can each be rated. The Esteban decision is the classic example.

    38 CFR 4.14
  • One service connected condition can open the door to another

    A condition caused by, or made worse by, a service connected condition can be service connected too. Sleep apnea linked to weight gain from a service connected condition, or depression linked to chronic pain, are common examples. This secondary path is in 38 CFR 3.310.

    38 CFR 3.310
  • Your rating can change by time period

    If a condition was worse during one stretch and better during another, VA can assign different ratings for those periods rather than one flat number. These are called staged ratings, and they flow from VA's duty to consider the whole recorded history under 38 CFR 4.1 and 4.2.

    38 CFR 4.2
  • Ratings are combined with a table, not added

    Two disabilities at 50 and 50 do not make 100. VA combines them with the table in 38 CFR 4.25, working from the largest down, then rounds to the nearest 10 only at the very end. This is why a 30 and a 20 can land on 40, not 50.

    38 CFR 4.25
  • If the schedule does not fit your case, VA can rate outside it

    When your disability picture is so unusual that the normal rating schedule does not capture it, for example frequent hospital stays or marked interference with work, VA can refer the case for an extraschedular rating. It is uncommon but real, under 38 CFR 3.321(b)(1).

    38 CFR 3.321
  • When you are between two ratings, the higher one should win

    If your symptoms sit between two rating levels, VA is supposed to assign the higher one when your overall disability picture more nearly matches it. This is the reasonable doubt rule applied to ratings, in 38 CFR 4.7.

    38 CFR 4.7
  • You do not have to check every box on the list

    The symptoms listed at each rating level are examples and guides, not a strict checklist. VA is not supposed to deny a level just because you do not have every single symptom named. See 38 CFR 4.21.

    38 CFR 4.21
Protections and money
  • You can lock in your start date before the full claim is ready

    Filing an intent to file holds your effective date for up to a year while you gather evidence. If you complete the claim within that year, back pay can run from the intent to file date, not the later submission. See 38 CFR 3.155.

    38 CFR 3.155
  • Older ratings get harder to take away

    A rating in place for 5 years is treated as stabilized, one in place for 10 years has protected service connection, and one in place for 20 years generally cannot be reduced below its level except for fraud. See 38 CFR 3.344, 3.957, and 3.951.

    38 CFR 3.344
  • VA cannot cut a rating without showing real, lasting improvement

    To reduce a rating, VA generally has to show actual improvement under the ordinary conditions of life and work, not just one better exam. The rules are in 38 CFR 3.344, and a proposed reduction comes with notice and a chance to respond first.

    38 CFR 3.344
  • You can be paid at the 100 percent rate without a 100 percent rating

    If service connected conditions keep you from holding steady, gainful work, VA can pay you at the 100 percent rate through TDIU, even if your combined rating is lower. Under the Rice decision, VA must consider TDIU whenever the record raises it, even if you never asked for it by name. See 38 CFR 4.16.

    38 CFR 4.16
  • Your back pay date is worth checking yourself

    Your award usually runs from the date you filed or the date entitlement arose, whichever is later, with special rules for claims filed within a year of leaving service. Knowing your effective date under 38 CFR 3.400 is how you catch retroactive pay that came up short.

    38 CFR 3.400
  • A clear error in an old decision can be fixed back to day one

    A final decision that contained a clear and unmistakable error can be revised at any time, and the correction runs back to the original date, not the date you pointed out the error. The bar is high: the error has to be undebatable. See 38 CFR 3.105(a).

    38 CFR 3.105
  • Needing help at home can add money on top of your rating

    If you need help with everyday activities, or are largely confined to your home because of disability, you may qualify for Aid and Attendance or Housebound payments added to your monthly amount. See 38 CFR 3.350 and 3.352.

    38 CFR 3.352
  • Surgery can earn a temporary 100 percent rating while you heal

    After certain surgeries, or when a service connected joint is immobilized in a cast, VA can grant a temporary 100 percent rating during recovery and then return you to your prior rating. It is easy to miss because you have to flag it. See 38 CFR 4.30.

    38 CFR 4.30
  • A long hospital stay can pay at 100 percent for that time

    If you are hospitalized more than 21 days for a service connected condition, VA can pay you at the 100 percent rate for that period, then drop back to your regular rating afterward. See 38 CFR 4.29.

    38 CFR 4.29
  • Even a 0 percent rating is worth winning

    A 0 percent rating still confirms the condition is service connected. That opens the door to secondary claims, to an increase later if it worsens, and can affect VA health care priority. Do not walk away from a noncompensable grant. See 38 CFR 4.31.

    38 CFR 4.31
  • A new law can pay you back to its start date

    When a new law or presumption adds a condition, your benefits can reach back to the law's effective date, up to one year before you filed. This matters for PACT Act and other presumptive expansions. See 38 CFR 3.114.

    38 CFR 3.114
  • If VA later finds lost service records, your date can reach back

    When VA later locates relevant official service records it did not have the first time, it must reconsider the claim, and the effective date can run back to your original filing, even years later. See 38 CFR 3.156(c).

    38 CFR 3.156
  • An increase can be backdated up to a year

    For a condition that got worse, your higher rating can be paid up to one year before you filed, if the record shows the worsening was clearly there during that window. See 38 CFR 3.400(o)(2).

    38 CFR 3.400
  • One total rating plus 60 percent more can mean extra money

    If you have a single disability rated 100 percent and other service connected disabilities adding to 60 percent or more, you may qualify for housebound special monthly compensation, paid on top of the 100 percent rate. See 38 CFR 3.350(i).

    38 CFR 3.350
Was your C&P exam done right? Open the checklist
If a VA decision on this came back wrong

You have three review lanes, pick the one that fits the situation.

Under the Appeals Modernization Act (38 CFR 3.2500), a Higher Level Review or a Board Appeal must be requested within one year of the decision notice. A Supplemental Claim can generally be filed at any time after the decision, but filing any of the three within that one year window is what keeps the claim continuously pursued and protects the original effective date; wait longer and a later award may start from the new filing date instead.

Filing for an Increased Rating When a Condition Gets Worse

If a service connected condition has grown more severe, you can ask VA to evaluate it at a higher level. A special effective date rule under 38 CFR 3.400(o)(2) can reach back up to a year when the worsening is factually ascertainable. Here is how the increase claim works.

How to Increase Your VA Disability Rating

If a service connected condition has worsened, you can ask VA for a higher rating. Here are the three honest routes (file for an increase, add a secondary condition, or pursue TDIU), the evidence that actually moves a rating, and the one reduction risk to understand before you file.

VA Disability Back Pay: How Far Back It Goes

Back pay is the lump sum VA owes you for the months between your effective date and the day your award is processed. How far it reaches depends on your effective date under 38 CFR 3.400. Here is how the intent to file, the one year window after separation, and Nehmer can each extend your back pay.

Staged Ratings and Extra-schedular Ratings (38 CFR 3.321(b))

Two tools for when one flat percentage does not fit: staged ratings, for when severity changed over time (Fenderson, Hart), and extra-schedular ratings under 38 CFR 3.321(b), for when the schedule does not capture your disability picture (the Thun three step test).

State benefits stack with VA disability

Your rating may also qualify you for state-level benefits.

VA compensation is federal, but every state layers its own benefits on top. Many states reduce or waive property tax for disabled veterans, and many offer license, tuition, or vehicle benefits at various rating levels. The thresholds, dollar amounts, and eligibility rules vary widely from state to state, so the reliable answer is always your own state's guide.
