- Document if patient is currently on anti-epileptic medications
- For active epilepsy, specify type and whether intractable
- Note any precipitating factors for historical seizures
Common Coding Scenarios
Documentation:
"History of febrile seizures as a child, no seizures for 20 years, not on medication."
Code:
Z86.69 - Personal history of other diseases of the nervous system
Rationale:
Use Z86.69 when seizure history is truly resolved and patient is not on anti-epileptic drugs.
Documentation:
"Epilepsy controlled on levetiracetam, no seizures for 2 years but continues medication."
Code:
G40.909 - Epilepsy, unspecified, not intractable, without status epilepticus
Rationale:
Even if seizure-free, if patient remains on anti-epileptic medication, code the active condition, not history.
Frequently Asked Questions
Z86.69 (Personal history of other diseases of the nervous system) is used for a truly resolved history of seizures when the patient is no longer on medication and has no active seizure disorder.
Use Z86.69 only when seizures have completely resolved and the patient is off all anti-epileptic medications. If the patient has active epilepsy (even if controlled) or takes seizure medications, use the appropriate G40 code.
Use G40.x codes for epilepsy even when well-controlled on medication. 'Not intractable' indicates good seizure control. Z86.69 is only for truly resolved conditions.
