0.000What This Code Means
A form of epilepsy that doesn't fit other specific categories and cannot be adequately controlled with medication, currently experiencing a prolonged seizure state.
Coding Tips
- •Intractable epilepsy indicates medication-resistant seizures; document failed medication trials
- •Status epilepticus in intractable epilepsy represents a critical emergency requiring specialized intervention
Clinical Significance
Other epilepsy, intractable, with status epilepticus represents a critical combination of drug-resistant epilepsy in a life-threatening prolonged seizure state. These patients have failed adequate medication trials and are in acute seizure emergency, typically requiring ICU-level care, IV medications, and possibly intubation. This is among the highest-acuity epilepsy presentations.
Documentation Requirements
- ✓Documentation of intractable/drug-resistant epilepsy with failed medication trials
- ✓Active status epilepticus documented during the encounter
- ✓List of antiepileptic drugs attempted and failed
- ✓Emergency interventions and ICU care provided
- ✓Epilepsy type documentation explaining why specific syndromes do not apply
- ✓Assessment for surgical or device-based treatment candidacy
