Prior authorization

Drugs requiring prior authorization (PA) or having any other restrictions are identified in the printable formulary (PDF) of the AmeriHealth Caritas Louisiana Formulary and through the searchable formulary

The prescriber must complete, sign and submit a request for prior authorization or an override of a drug restriction on behalf of a member. Requests from pharmacists are not accepted, except to validate a member's historical drug use for purposes of grandfathering certain medications.

Use an online PA request form to request an override of any restriction accompanying a drug listed in the print formulary (including prior authorization).

Prescribers may also request PA medications by calling the PerformRx Provider Services Help Desk at 800-684-5502.


All Specialty Medications require prior authorization. These drugs are listed in the printable specialty formulary. Specialty medications are also included in the online searchable formulary.

For Prior Authorization forms for Specialty medication with "drug specific" criteria, use the prior authorization forms.

All forms need to be completed with required information, signed by the prescriber, and forwarded (by mail or fax) along with any supporting documentation to PerformRx.

In most cases where the prescribing health care professional/provider has not obtained prior authorization, members will receive a three-day emergency supply of the medication.
