Additional Info

• This is a wastebasket code for seizures in a person WITHOUT a prior known seizure disorder (epilepsy), that does not fall into one of these other categories
  • Seizure, febrile (febrile seizure)
  • Eclampsia (seizures must occur)
  • Alcohol withdrawal
• This code includes isolated seizures that fit the above
• This code includes myoclonic seizures that fit the above
  • Use Myoclonus for the symptom of myoclonus, but not for myoclonic seizure
