How to Submit Prior Authorization Requests to OptumRx

Simplify your prior authorization experience by submitting your requests via electronic prior authorization (ePA). We've partnered with various providers, including CoverMyMeds® and Surescripts®, making it easier for you to submit an ePA through the vendor of your choice.  Get started today through the OptumRx website at professionals.optumrx.com > Prior authorizations > Submit a prior authorization.  

To comply with federal and state requirements, we’ll accept fax prior authorizations for Medicare Part D, for states with their own mandated prior authorization forms, and for Massachusetts, Rhode Island, South Carolina and Texas. To obtain a fax prior authorization form, go to our website or call the OptumRx prior authorization team.


If you’re unable to submit requests online or need additional information, call the OptumRx prior authorization team at 800-711-4555, 5 a.m. – 10 p.m. Pacific Time, Monday – Friday.
