What This Code Means

A type of epilepsy caused by a known brain condition with complex partial seizures that responds to medication, without current prolonged seizure activity.

Coding Tips

  • The '20' indicates symptomatic with complex partial seizures; the final '9' indicates no status epilepticus
  • Verify that seizures are not intractable and document current seizure control status

Clinical Significance

This code represents the stable baseline state of symptomatic focal epilepsy with complex partial seizures — medication-controlled and not in status epilepticus. Complex partial seizures involve impaired consciousness, making them more functionally disabling than simple partial seizures. These patients require ongoing medication management and monitoring for seizure control.

Documentation Requirements

  • Documentation of symptomatic focal epilepsy with identified underlying cause
  • Complex partial seizure type documented (impaired awareness during seizures)
  • Current antiepileptic medication regimen and dosing
  • Seizure frequency and control status
  • Underlying etiology documented and coded separately
  • Confirmation that seizures are NOT intractable and patient is NOT in status epilepticus
