Learn Which Conditions Are ‘External’ for Epileptic Seizures

Question: The ED physician treated a patient with alcohol-related epileptic seizures. The seizures were not intractable and included status epilepticus. Should I report a combination of codes for this condition?

Answer: There actually is a single code for this condition. On the claim, report G40.501 (Epileptic seizures related to external causes, not intractable, with status epilepticus).

Alcohol-related epileptic seizures are represented with G40.501, as are these conditions:

  • Epileptic seizures related to drugs
  • Epileptic seizures related to hormonal changes
  • Epileptic seizures related to sleep deprivation
  • Epileptic seizures related to stress

1 more thing: While you can report a single ICD-10 code to represent the seizure, you might need another code(s) to back up your primary diagnosis. In the notes beneath the G40.5 entry in ICD-10, you’ll see these instructions:

  • “Code also, if applicable, associated epilepsy and recurrent seizures (G40.-)
  • “Use additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)”
