0.000What This Code Means
Epilepsy of unknown type that is not resistant to medication, currently experiencing status epilepticus (prolonged or repeated seizures without recovery).
Coding Tips
- •Status epilepticus is a medical emergency; ensure documentation clearly indicates this acute condition
- •The '901' ending indicates both unspecified epilepsy AND status epilepticus occurring together
Clinical Significance
Unspecified epilepsy with status epilepticus indicates a patient in a life-threatening prolonged seizure state whose epilepsy type has not been determined. This typically occurs in emergency settings where the immediate priority is terminating the seizure rather than classifying the epilepsy type. Status epilepticus requires emergent treatment regardless of epilepsy classification.
Documentation Requirements
- ✓Documentation of active status epilepticus during the encounter
- ✓Statement that epilepsy type is unspecified or undetermined
- ✓Confirmation seizures are not intractable (medication-responsive) or intractability is unknown
- ✓Emergency interventions provided (IV benzodiazepines, loading doses of antiepileptics)
- ✓Plan for diagnostic workup to determine epilepsy type
- ✓Duration and characteristics of status epilepticus
