Pharmacy Prior Authorization Timeframes

    Our pharmacy vendor, Navitus, will provide a prior authorization decision at the time of the call, when the caller is requesting a Medicaid prior authoriztion and has all the necessary information required to complete the prior authorization review.

    For all others STAR/STAR Kids Medicaid prior authorization requests, Navitus will notify the prescriber's office of a prior authorization denial or approval no later than 24 hours after receipt.

    If Navitus 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 situation, Navitus will allow the pharmacy to dispense a 72-hour supply of the drug. This requirement applies to drugs which can be filled as a 72-hour supply.
