Prescribers can also submit a prior authorization request over the phone by calling Navitus Customer Care and speaking with the Prior Authorization department between 8 am and 5 pm CST. After hours, providers will have the option to leave a voicemail.

Pharmacy Prior Authorization Timelines

Standard request: A prescriber can submit a Prior Authorization Form to Navitus via U.S. Mail or fax, or they can contact our call center to speak to a Prior Authorization Specialist. The request will be processed as quickly as possible once all required information has been provided. 

Urgent request: A prescriber may notify Navitus by phone or fax of an urgent request submission. A decision will be made within 24 hours of receipt. The member and prescriber are notified as soon as the decision has been made.
