On October 1, 2020, International Classification of Diseases, (ICD-10) code G40.83 becomes available for Dravet Syndrome with the following sub-codes:

  • 834 for Dravet Syndrome, interactable without status epilepticus.

The revised criteria document is available for review.

On July 31, 2020, the Food and Drug Administration (FDA) approved Epidiolex for the treatment of seizures associated with tuberous sclerosis complex in patients one year of age and older. The revised criteria document with this new indication is available for review.

Both clinical prior authorizations are optional for the managed care organizations (MCOs) to implement. The Pharmacy Clinical Prior Authorization Assistance Chart shows the prior authorization each MCO uses and how those authorizations relate to the authorizations used for traditional Medicaid claim processing. This chart is updated quarterly.
