ICD-10 Code G40.411 – Other generalized epilepsy and epileptic syndromes, intractable, with status epilepticus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G40.411 – Other generalized epilepsy and epileptic syndromes, intractable, with status epilepticus
What it is
This code identifies a generalized epilepsy or epileptic syndrome that does not fit a more specific category, is resistant to treatment, and is complicated by status epilepticus. It indicates a prolonged seizure emergency in a patient with ongoing epilepsy.
Clinical signs
Typical findings include generalized seizure activity with impaired awareness or convulsions that persist or recur without recovery. Clinical features vary; refer to documentation for the exact syndrome and whether status epilepticus was confirmed.
When to use this code
Use this code when the provider documents an other generalized epilepsy or epileptic syndrome as intractable and also documents status epilepticus. It may apply during emergency care, inpatient admission, or follow-up notes if the condition remains uncontrolled. Confirm that the record supports both refractoriness and status epilepticus.
Do not use for
Do not use it for generalized epilepsy without intractability, or for seizures that are not documented as status epilepticus. If the record names a more specific epilepsy syndrome, code that diagnosis instead.
Coding tip
Verify the words “intractable” and “status epilepticus” in the provider note before assigning G40.411.
