ICD-10 Code G40.419 – Other generalized epilepsy and epileptic syndromes, intractable, without status epilepticus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G40.419 – Other generalized epilepsy and epileptic syndromes, intractable, without status epilepticus
What it is
This code identifies a generalized epilepsy syndrome that does not fit a more specific category and is resistant to treatment. It applies when the condition is chronic and no status epilepticus is documented.
Clinical signs
Typical findings may include recurrent generalized seizures involving both sides of the brain. Clinical features vary; refer to documentation for the exact syndrome and whether seizures remain uncontrolled despite therapy.
When to use this code
Use G40.419 when the record clearly states other generalized epilepsy or an epileptic syndrome and specifies that it is intractable. Confirm that the provider documents absence of status epilepticus. If the chart names a more specific generalized epilepsy syndrome, code that diagnosis instead.
Do not use for
Do not use this code if the epilepsy is not documented as intractable or if status epilepticus is present. Check documentation when the seizure type or syndrome is more specific.
Coding tip
Look for the exact terms “intractable” and “without status epilepticus” in the provider note before assigning G40.419.
