Migraines are more than “just headaches.”

For many veterans, migraines can mean hours spent in a dark room, missed work, nausea, blurred vision, sensitivity to light and sound, and days when normal life comes to a complete stop.

And yet, migraine claims are still one of the most misunderstood VA disability claims.

At Warriors Supporting Warriors, we hear it all the time:
“I have migraines, but I don’t know if they’re bad enough for a VA rating.”
Or worse:
“The VA gave me 0% or 30%, but my migraines are ruining my ability to work.”

The good news is that the VA’s migraine rating system has been clarified in recent years, especially around what counts as a prostrating or completely prostrating attack. The underlying rating percentages under Diagnostic Code 8100 did not change, but VA guidance clarified how the VA should evaluate evidence for higher ratings—especially the 50% level. The source article notes that on September 14, 2023, the VBA updated the M21-1 to further define prostrating migraine headaches and evidence requirements.

This matters because many veterans may qualify for a higher migraine rating than they realize.

How the VA Rates Migraine Headaches

Migraine headaches are rated under 38 C.F.R. § 4.124a, Diagnostic Code 8100.

The VA still uses four possible ratings:

• 0% – Less frequent attacks

• 10% – Characteristic prostrating attacks averaging one in two months over the last several months

• 30% – Characteristic prostrating attacks occurring about once a month over the last several months

• 50% – Very frequent, completely prostrating, and prolonged attacks that cause severe economic inadaptability

The source article confirms that migraine ratings remain 0%, 10%, 30%, and 50%, and that what changed was the clarification of symptoms and impairment—particularly at the 50% level.

What Changed in the “New” VA Migraine Rating?

This is important:

The actual rating percentages did not change.

Veterans still receive ratings from 0% to 50% under the same diagnostic code.

What changed is the VA’s internal guidance on how raters should interpret:

• What counts as a prostrating migraine

• What counts as a completely prostrating migraine

• How to evaluate frequency

• How to evaluate work impairment

• What types of medical and lay evidence can support the claim

In plain language, this means the VA has become more specific about what evidence can support a higher migraine rating—especially when a veteran is trying to prove 50% severity. The article specifically states that the VBA updated the M21-1 to provide “further clarification” on prostrating migraine headaches and evidence requirements.

What Does “Prostrating” Mean for a VA Migraine Claim?

The word prostrating is one of the most important words in a migraine claim.

A prostrating migraine generally means an attack so severe that it forces you to stop what you’re doing and rest.

This can look like:

• Lying down in a dark room

• Being unable to tolerate light or noise

• Having nausea or vomiting

• Missing work or needing to leave early

• Being unable to read, drive, focus, or carry on normal activity

• Needing to sleep or completely rest until the migraine passes

The source material explains that the VA can consider symptoms beyond head pain alone and must evaluate the full impact of the migraine attack, including associated symptoms like photophobia, nausea, and dizziness, not just the headache itself.

That is a big deal.

Because a veteran may say, “I can still function a little,” while the actual symptoms clearly show the migraine is prostrating.

What Is a “Completely Prostrating” Migraine?

For the highest rating—50%—the VA looks for attacks that are:

• Very frequent

• Completely prostrating

• Prolonged

• Causing severe economic inadaptability

That means the migraine is not just painful.

It is the kind of attack that can take you out of commission.

A completely prostrating migraine often means:

• You must stop all activity

• You cannot work during the episode

• You need to lie down or sleep

• Symptoms last for hours (or longer)

• The attack causes major disruption to employment or reliability

The source article explains that work impairment is a key factor for a 50% rating, and the VA now gives clearer guidance on what evidence can show this level of severity.

VA Migraine Rating Percentages Explained

0% VA Rating for Migraines

A 0% rating generally means the VA acknowledges the condition but considers the attacks less frequent and not meeting the compensable criteria.

This is common when:

• The migraines are documented, but

• The evidence does not clearly show prostrating attacks often enough

10% VA Rating for Migraines

A 10% rating may apply when:

• You have characteristic prostrating attacks

• They happen about once every two months over the last several months

This is a compensable rating, but many veterans who deserve 30% or 50% are often underrated here.

30% VA Rating for Migraines

A 30% rating may apply when:

• You have characteristic prostrating attacks

• They occur about once a month over the last several months

This is where many veterans land—but it may still be too low if the migraines are happening more often or are seriously affecting work.

50% VA Rating for Migraines

A 50% rating is the highest schedular rating for migraines.

It may apply when:

• Attacks are very frequent

• They are completely prostrating

• They are prolonged

• They cause severe economic inadaptability

The source article notes that “very frequent” can be understood as attacks occurring less than one month apart over the last several months, and that headache journals, prescription refills, witness statements, and credible lay evidence may help prove frequency and occupational impairment.

Can Lay Evidence Help Prove a Migraine Claim?

Yes — absolutely.

This is one of the most important takeaways.

The VA does not require every migraine to be documented in a medical office visit.

That would be unrealistic.

The source material specifically explains that a veteran’s own testimony can establish prostration if it is credible and if the symptoms are medically recognized as migraine-related. It also states that the absence of treatment reports is not necessarily proof against frequency, because many veterans do not seek treatment for every single attack.

That means evidence can include:

• Your personal statement

• A spouse or family member statement

• A coworker or supervisor statement

• A migraine journal

• A headache tracker app

• Time missed from work

• Prescription refill history

This is huge for veterans who have been under-documented in the medical system.

What Evidence Makes a Migraine Claim Stronger?

To strengthen a migraine claim, veterans should consider building evidence in three categories:

1. Medical Evidence

• Formal migraine diagnosis

• Neurology records

• Primary care notes

• ER or urgent care visits

• Prescription medications

• Migraine DBQ

• Nexus letter (if needed for service connection or secondary connection)

2. Lay Evidence

• Personal statement explaining frequency, severity, and duration

• Buddy statement from spouse, friend, or coworker

• Description of what happens during an attack

• Explanation of how often you must lie down, miss work, or stop functioning

3. Tracking Evidence

• Migraine log or journal

• Headache tracker app entries

• Dates, duration, symptoms, triggers

• Missed work or reduced productivity

• Days you had to isolate, rest, or sleep

The article specifically says that headache journals or mobile tracking apps may be accepted as credible lay evidence for:

• frequency

• prostration

• occupational impairment

Even veterans on Reddit repeatedly emphasize that “the log is everything” for migraine claims, with community advice focusing on tracking dates, duration, meds, nausea, and whether the veteran had to lie down or miss work.

Can Migraines Be Claimed as Secondary Service Connection?

Yes.

Many veterans are granted migraines as a secondary condition, depending on the medical facts.

Common theories may include migraines secondary to:

• PTSD

• Tinnitus

• Sleep apnea

• TBI

• Neck conditions

• Chronic pain

• Medication side effects

The exact connection depends on medical evidence, but secondary migraine claims are common. In community discussions, veterans frequently report filing or being rated for migraines secondary to other service-connected conditions, including insomnia and tinnitus, as long as they have evidence like a DBQ, nexus letter, and headache log.

How to Better Describe a Migraine to the VA

Instead of only saying:

• “I get headaches”

• “They’re bad”

• “They happen a lot”

Describe them like this:

• “I get migraines 4–6 times per month.”

• “When they happen, I have to lie down in a dark room.”

• “I cannot tolerate light, sound, or screens.”

• “I get nausea and sometimes vomiting.”

• “I miss work or have to stop working.”

• “The attacks last 4–12 hours.”

• “Medication does not always stop them.”

• “I’m unable to function normally until the episode passes.”

That kind of detail matters.

Migraines are often invisible to other people—but they can completely disrupt a veteran’s life.

And the biggest misunderstanding is this:

The “new” VA migraine rating did not create new percentages.
Instead, it gave the VA clearer guidance on how to evaluate prostrating attacks, complete prostration, frequency, and work impairment.

That means veterans who were previously underrated may now have a stronger path to proving what they’re really dealing with.
