Epilepsy — VA Disability Rating Criteria (DC 8910/8911)
Diagnostic Code 8910 · 38 CFR §4.124a
What Is It?
Epilepsy is a neurological condition characterized by recurrent seizures — sudden surges of electrical activity in the brain that can cause a range of symptoms from brief staring spells to full-body convulsions with loss of consciousness. The VA uses two main codes: DC 8910 for grand mal (generalized tonic-clonic) seizures involving convulsions and loss of consciousness, and DC 8911 for petit mal (absence) or other partial seizures. Veterans may develop epilepsy from traumatic brain injuries sustained during service, blast exposure, or other neurological trauma. The VA rates epilepsy based on seizure frequency and type.
Rating Criteria
| Rating | Criteria |
|---|---|
| 100% | For grand mal: averaging at least one major seizure per month over the last year. At this level, seizures are essentially uncontrolled despite medication and the veteran is unable to maintain employment or safe independent living. |
| 80% | For grand mal: averaging at least one major seizure in three months over the last year, or more than one minor seizure per week with periods of unconsciousness. The condition severely limits independence. |
| 60% | For grand mal: averaging at least one major seizure in four months over the last year, or more than ten minor seizures weekly. Seizure activity is frequent enough to significantly disrupt employment and daily activities. |
| 40% | For grand mal: at least one major seizure in the last six months, or at least two major seizures in the last year. For petit mal: one minor seizure weekly or more. The seizures are clearly interfering with daily function. |
| 20% | For grand mal epilepsy: at least one major seizure in the last two years, or at least two minor seizures in the last six months. For petit mal: a minor seizure occurs at a frequency that is clearly documented but infrequent. |
| 10% | You have a confirmed diagnosis of epilepsy with a history of seizures. This is the minimum rating when the condition is established and controlled with medication but seizures are not currently occurring. |
Evidence Needed
Seizure logs documenting every episode — date, time, type, duration, and what happened during and after — are critical. EEG results showing epileptic activity support the diagnosis. Emergency room records from seizure episodes, neurologist treatment records, and medication history (especially dose changes indicating the condition is not well controlled) are all important.
C&P Exam Tips
Bring a seizure diary to your exam covering at least the last year. The rating is based entirely on seizure frequency, so this documentation is essential. Describe what happens during your seizures — do you lose consciousness, fall, have convulsions, lose bladder control? How long does recovery take after a seizure? If someone witnesses your seizures, a buddy statement from them describing what they observe is very valuable.
How to File
File under DC 8910 for grand mal epilepsy or DC 8911 for petit mal/partial seizures. Include your seizure diary, EEG results, neurologist records, and medication list. If epilepsy developed after a service-connected TBI, file as secondary to TBI (DC 8045). A neurologist nexus letter is strongly recommended.
Common Mistakes
Not keeping a seizure diary is the biggest mistake. The VA rating is directly tied to seizure frequency, and without a log the examiner has to estimate — usually conservatively. Another mistake is not distinguishing between major and minor seizures in your records. Major seizures (convulsions, loss of consciousness) carry higher ratings than minor ones (brief staring spells, focal symptoms). Make sure your diary specifies the type of each episode. Finally, some veterans stop claiming epilepsy when medications reduce their seizures. Even well-controlled epilepsy on medication warrants a rating.
Frequently Asked Questions
Can I drive with an epilepsy rating?
Driving restrictions vary by state, not by VA rating. Most states require a seizure-free period (typically 6 to 12 months) before allowing you to drive. Your VA rating does not directly affect driving privileges, but it does document your seizure history.
What if my seizures are controlled by medication?
Even if medication controls your seizures, you still qualify for a rating. The minimum is 10 percent for a confirmed diagnosis. If reducing or missing medication causes breakthrough seizures, document those episodes as they show the condition is still active.
Is epilepsy connected to TBI?
Yes, post-traumatic epilepsy is a well-recognized condition. If you had a traumatic brain injury during service and later developed seizures, secondary service connection through TBI is a strong claim path. Studies show TBI significantly increases the risk of developing epilepsy.
