The Department of Veterans Affairs (VA) disability rating system provides financial compensation to veterans whose medical conditions are connected to their military service. This system assigns a percentage, ranging from 0% to 100%, based on the severity of the service-connected disability and its impact on the veteran’s life and ability to function. For veterans who experience debilitating head pain, the VA evaluates the condition specifically as migraine headaches. The rating assigned reflects the frequency and intensity of the attacks, which is the focus of the criteria.
Establishing Service Connection
Before the VA can assign any percentage rating, a veteran must first establish a “service connection” for their migraine condition. This foundational step proves the disability is a result of military service. To establish this link, the VA requires three distinct components in the veteran’s claim documentation.
The first component is a current medical diagnosis of migraines from a qualified healthcare professional. The second component is evidence of an in-service event, injury, disease, or aggravation that occurred during the veteran’s time in service. This could be anything from a documented head injury to exposure to environmental toxins or the chronic stress of combat or deployment.
The third component is the “nexus,” which is a medical link between the current diagnosis and the in-service event. A medical professional must provide an opinion stating that the veteran’s current migraines are “at least as likely as not” caused or aggravated by the documented incident during service. Without this established connection, the VA rating criteria for severity become irrelevant, as the condition cannot be considered service-connected for compensation purposes.
The VA Disability Rating Schedule for Migraines
Migraine headaches are evaluated under Diagnostic Code 8100, which is part of the VA Schedule for Rating Disabilities (38 CFR 4.124a). This code outlines four specific percentage levels—0%, 10%, 30%, and 50%—determined almost entirely by the frequency and nature of “prostrating” attacks. A prostrating attack is defined as a migraine episode that requires the veteran to cease all activity and lie down for a period of time due to the severity of the symptoms.
The lowest rating is 0%, assigned when the veteran has a diagnosis but the attacks are infrequent or are not prostrating. This rating is non-compensable but officially recognizes the condition as service-connected. A 10% rating requires characteristic prostrating attacks that occur, on average, once every two months.
A 30% rating is warranted for characteristic prostrating attacks that increase in frequency to occur, on average, once a month. This level signifies a greater disruption to a veteran’s routine and daily activities. The highest schedular rating the VA assigns for migraines is 50%, reserved for the most severe cases.
The 50% rating requires “very frequent completely prostrating and prolonged attacks productive of severe economic inadaptability.” “Very frequent” generally means attacks that occur more often than once a month, such as weekly or near-weekly. “Completely prostrating” indicates a total inability to engage in ordinary activities during the attack.
The requirement of “severe economic inadaptability” means the migraines severely interfere with the veteran’s ability to maintain substantially gainful employment. This often results in frequent absences, reduced productivity, or the need for significant job accommodations. This highest rating acknowledges the debilitating impact of chronic, severe migraines on a veteran’s occupational and social functioning.
Essential Documentation for a Strong Claim
To secure a disability rating, particularly the highest 50% rating, the veteran must provide evidence that proves the condition’s severity. The most persuasive evidence is a detailed symptom log or headache journal maintained over several months. This journal should meticulously track the date, frequency, duration, and specific symptoms of each attack, specifically noting whether the attack was prostrating and for how long.
This personal documentation establishes a pattern of frequency and clearly demonstrates the debilitating nature of the attacks, directly addressing the criteria for the 10%, 30%, and 50% ratings. The veteran should also document how the migraines force them to miss work, lose productivity, or require assistance with domestic responsibilities. This information directly proves the “severe economic inadaptability” required for the 50% rating.
Statements from employers, spouses, family members, or friends, known as “buddy statements” or lay evidence, are also highly valuable in corroborating the veteran’s claims. These statements provide an external perspective on the veteran’s functional limitations, detailing observed instances of prostrating attacks and the resulting negative impact on work and daily life. The veteran will also undergo a Compensation and Pension (C&P) exam, where the VA doctor will review the evidence and complete a Disability Benefits Questionnaire (DBQ). Submitting a private medical opinion or nexus letter from a treating physician can further bolster the claim.
