2015 ICD-10-CM Diagnosis Code G40.4
Other generalized epilepsy and epileptic syndromes
G40.4 is not a billable ICD-10-CM diagnosis code and cannot be used to indicate a medical diagnosis.
On October 1, 2015 ICD-10-CM will replace ICD-9-CM in the United States, therefore, G40.4 - and all other ICD-10-CM codes - should only be used for training or planning purposes until then.
This is the American ICD-10-CM version of G40.4. Other international ICD-10 versions may differ.
