Medicaid's rules concerning generic substitutions for anticonvulsant medications (AEDs) are presented in this chart. Where indicated, a state has a Preferred Drug List (PDL) that includes AEDs. Where known, any AEDs that are not on the PDL for a state are listed. Some AEDs require Prior Approval (PA) before Medicaid will cover their use. Approval must be requested by the prescribing physician. Please read the "Unique Medicaid Features" column carefully for your state. Any questions should be directed to those authorities.
|
PDL = Preferred Drug List.
* Drugs omitted from a state PDL may still be covered; Consult with agency to determine coverage. † Some listed agents on a PDL may still require prior authorization for approval. ‡ Medications listed by generic name unless alternative dosage form is not covered. AED = Anticonvulsant drug. PA = Prior Authorization required. MCO = managed care organization. NA = no preferred drug list mentioned in state Medicaid documents. Unknown= preferred drug list mentioned in state Medicaid documents, but contents were not available. |

The information presented in this chart is for reference only. Prescribers, please consult the State Medicaid Office in your state for specific requirements and wording to be sure that medications are dispensed as you have determined appropriate for your patient. Any questions should be directed to those authorities.
