Which Optum Rx fax number should I use?
A coverage determination asks the plan to cover a drug or grant an exception. A redetermination appeals a coverage decision already made. These numbers are published for the CalPERS Medicare material linked here; compare your own plan’s form before using them.
What to include in your fax to Optum Rx
For a coverage request, use the prior authorization or coverage form with the prescriber’s supporting information. For an appeal, identify the denial and explain why it should be reconsidered, with relevant evidence.
Check the destination and prepare your cover page
Name the receiving department and the hospital, clinic or service involved. Add the document title, page count and a callback number. Put patient identifiers and authorization details in the fields the official form requests; a cover page does not replace signed consent.
Open the official source above and check the current instructions. A reviewed source confirms a published number, not live availability. Toll-free numbers can still incur sending-service or international charges.
Confirm delivery and follow up with Optum Rx
Keep the transmission result and a copy of the documents. Confirm with the receiving department that the packet is complete and can be processed; a delivery receipt does not establish acceptance or a decision. These are fax destinations, not voice support lines. Check with Optum Rx before sending a duplicate.
