Related code is G40.319: Generalized idiopathic epilepsy and epileptic syndromes, intractable, without status epilepticus

G40.211: Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with complex partial seizures, intractable, without status epilepticus

Related code is G40.219: Localization related (focal) (partial) symptomatic epilepsy and epileptic syndromes with complex partial seizures, intractable, without status epilepticus

G40.401: Other generalized epilepsy and epileptic syndromes, not intractable, with status epilepticus

Related code is G40.409: Other generalized epilepsy and epileptic syndromes, not intractable, without status epilepticus

G40.501: Epileptic seizures related to external causes, not intractable, with status epilepticus

Related code is G40.509: Epileptic seizures related to external causes, not intractable without status epilepticus

G40.901: Epilepsy, unspecified, not intractable, with status epilepticus

Frequently asked questions

When to use an epilepsy ICD code?

ICD-10-CM codes for epilepsy should be used in medical documentation for diagnosis, treatment planning, and billing. These codes provide a standardized method for healthcare professionals to identify and categorize epilepsy types and severities.

What are the common treatments for epilepsy?

Common treatments generally involve anti-seizure medications like phenytoin, valproic acid, and lamotrigine. For some intractable cases, surgical procedures like vagus nerve stimulation or resective surgery may be considered.

What does a diagnosis code for epilepsy mean?
