Prescriber offices calling our Pharmacy Prior Authorization call center will receive an authorization approval or denial immediately. For all other prior authorization requests, Amerigroup will notify the prescriber’s office of an approval or denial no later than 24 hours after receipt.

If Amerigroup cannot provide a response to the prior authorization request within 24 hours after receipt or the prescriber is not available to make a prior authorization request because it is after the prescriber’s office hours and the dispensing pharmacist determines it is an emergency, the pharmacy has the ability to dispense a 72-hour supply of the drug.

Providers must be prepared to supply relevant clinical information regarding the member’s need for a nonpreferred product or a medication requiring prior authorization. Only the prescribing physician or one of their staff representatives can request prior authorization. Decisions are based on medical necessity and are determined according to VDP-established medical criteria. Most approved requests for prior authorization will be valid for one year, although some medications may require review more often.
