Blue Book listing 11.02
Epilepsy and Seizure Disorder SSDI Claims
SSA counts seizures under Blue Book listing 11.02: their type, how often they happen, and whether they continue despite at least three consecutive months of following prescribed treatment. Generalized tonic-clonic seizures and dyscognitive seizures carry different frequency thresholds, and two paths also require a marked functional limitation.
SSA defines epilepsy as a pattern of recurrent, unprovoked seizures caused by abnormal electrical activity in the brain. An epilepsy claim is unusual among neurological claims because so much of it is arithmetic. The listing sets a seizure count, a seizure type and a time window, and the file either documents those numbers or it does not.
That math applies the same way to Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI). Below we cover the four paths in the listing, the counting rules, the residual functional capacity (RFC) route for seizures that fall short of it, and the records that decide the claim.
SSA Blue Book listing
11.02
Neurological
The criteria are set out below in plain language.
What are the seizure frequency rules in listing 11.02?
A dyscognitive seizure, formerly called a complex partial seizure, alters consciousness without convulsions.
Listing 11.02 first requires that your epilepsy be documented by a detailed description of a typical seizure. It then sets four paths, and you need to meet only one. Each requires that the seizures continue despite adherence to prescribed treatment.
- Paragraph A: generalized tonic-clonic seizures occurring at least once a month for at least 3 consecutive months.
- Paragraph B: dyscognitive seizures occurring at least once a week for at least 3 consecutive months.
- Paragraph C: generalized tonic-clonic seizures occurring at least once every 2 months for at least 4 consecutive months, plus a marked limitation in physical functioning or in one of four areas of mental functioning.
- Paragraph D: dyscognitive seizures occurring at least once every 2 weeks for at least 3 consecutive months, plus the same kind of marked limitation as paragraph C.
The two seizure types are defined in section 11.00H of the neurological listings. A generalized tonic-clonic seizure involves loss of consciousness, a tonic phase of sudden muscle tensing with loss of postural control, and then a clonic phase of rapid contraction and relaxation. Tongue biting, incontinence and injuries from falls may occur. A dyscognitive seizure, formerly called a complex partial seizure, alters consciousness without convulsions. It may show as blank staring, changes in facial expression, or automatisms such as lip smacking, chewing or repeated simple actions.
The four mental areas used in paragraphs C and D are understanding, remembering or applying information; interacting with others; concentrating, persisting or maintaining pace; and adapting or managing oneself. Memory trouble after seizures and medication-related slowing often belong in this part of the analysis.
How SSA counts seizures for a disability claim
Section 11.00H4 sets counting rules that can change a seizure total, so they shape what your records need to show.
- The counting period cannot begin earlier than one month after prescribed treatment starts.
- Multiple seizures within a 24-hour period count as one seizure.
- Status epilepticus, a continuous series of seizures without a return to consciousness in between, counts as one seizure.
- A dyscognitive seizure that progresses into a generalized tonic-clonic seizure counts as one generalized tonic-clonic seizure.
- Seizures that happen during a period when you were not following prescribed treatment, without a good reason, are not counted.
Adherence has its own definition in section 11.00C. It means you have taken prescribed medication or followed other prescribed treatment for three consecutive months, and your seizures still meet the listing. Treatment can come from a health care facility you visit regularly even if you do not see the same physician each time.
The 24-hour rule matters most for people whose seizures come in clusters. Five seizures on one bad day count as one. A log that lists clusters by date, rather than a running total, shows SSA how many qualifying days you actually had. If you are still early in the process, our guide to applying for disability covers how to list every treating source so these records reach the file.
The RFC route when seizures fall short of the listing
Many people with epilepsy have seizures that are serious but less frequent than the listing requires. SSA then assesses your residual functional capacity, which 20 CFR 404.1545 defines as the most you can still do despite your limitations. That regulation names epilepsy by name among the impairments that can affect work abilities beyond strength.
For seizure disorders, the RFC limits are mostly about safety and reliability rather than lifting or walking:
- No work at unprotected heights, near open water, or around dangerous moving machinery, because a seizure there carries a risk of serious injury.
- No commercial driving or operating vehicles as part of the job.
- Time off task during and after a seizure, including the confusion and exhaustion that can follow one, which affects pace and attendance.
- Absences on seizure days and for neurology visits or medication changes.
- Medication side effects such as drowsiness or slowed thinking, which section 11.00G4b tells SSA to consider and which can limit attention and concentration.
Hazard restrictions on their own often leave a range of jobs. The claim usually turns on the reliability limits: how often a seizure takes you out of the workday, how long recovery takes, and whether any employer would tolerate that pattern on a regular and continuing basis.
Evidence that decides an epilepsy disability claim
The listing and section 11.00H2 put the weight on description. SSA needs at least one detailed description of your seizures from someone who has seen at least one of your typical seizures, preferably a medical professional. If you have more than one seizure type, SSA needs a description of each.
- A seizure log with the date, time, type, length and recovery period of each seizure, kept from the start of treatment.
- Neurologist notes that record seizure frequency at each visit and every medication and dose change.
- Pharmacy refill records, which show adherence across the three-month window better than a statement does.
- Emergency room and ambulance records from seizures that led to injury or transport.
- Written statements from family members, coworkers or caregivers who have watched your seizures, describing what they saw step by step.
- EEG results already in your records. EEG is not required, and SSA will not purchase one, but it evaluates results that exist with everything else.
A neurologist's note that says "seizures continue" does less than one that says "two generalized tonic-clonic seizures since the last visit on these dates, current dose confirmed." The second note does SSA's counting for it.
Why epilepsy disability claims are denied
Without an observer's description of a typical seizure, the listing's documentation requirement is not met, however frequent the seizures are.
The most common pattern we see in denied epilepsy files is an adherence gap with no explanation. A missed refill, a low medication level or a note that you stopped a drug, with nothing in the record about why, lets every seizure in that stretch drop out of the count.
The second pattern is seizures that exist only in the claimant's own account. Without an observer's description of a typical seizure, the listing's documentation requirement is not met, however frequent the seizures are. The third is a count that collapses under the 24-hour rule, where a file shows many seizures but few separate seizure days. Each of these is fixable with records, and a denied disability claim can be appealed with that evidence added.
Epilepsy Disability Claim Questions
Does SSA count psychogenic nonepileptic seizures under the epilepsy listing?
No. Section 11.00H1 says psychogenic nonepileptic seizures and pseudoseizures are not epileptic seizures for listing 11.02, and SSA does not count them toward the seizure totals. SSA evaluates them under the mental disorders body system in section 12.00 instead. If you have both epileptic and nonepileptic events, records that separate the two types protect the count for the epileptic ones.
What counts as a good reason for missing seizure medication?
Section 11.00H4 says SSA considers your physical, mental, educational and communicative limitations, including language barriers. Its examples include treatment that is very risky because of its consequences or unusual nature, and treatment you cannot afford when no free community resources are available. Seizures during a period with a documented good reason can still count, so write the reason down when it happens.
Will SSA order blood tests of my seizure medication level?
No. Section 11.00H3 says SSA does not require serum drug levels and will not purchase them. If levels already appear in your medical records, SSA evaluates them along with the rest of the evidence. A therapeutic level in your chart can help show adherence during the counting window, which is one reason to ask your neurologist whether levels are being checked.
