G40.311
ICD-10-CMGeneralized idiopathic epilepsy and epileptic syndromes, intractable, with status epilepticus
This code signifies a severe form of generalized idiopathic epilepsy where seizures are difficult to control with medication (intractable) and the patient is experiencing status epilepticus. Generalized idiopathic epilepsy involves seizures that affect both sides of the brain from the onset, with no identifiable underlying cause. Status epilepticus is a prolonged seizure or a series of seizures without full recovery of consciousness between them, representing a medical emergency.
This code is used when a patient with a documented diagnosis of generalized idiopathic epilepsy presents with intractable seizures and is currently in status epilepticus. Documentation must clearly state the generalized nature of the epilepsy, its idiopathic origin, the intractability of the seizures despite treatment, and the presence of status epilepticus. This code is typically assigned in acute care settings or during emergency department visits.
