ProDUR / Pharmacy Prior Authorization Unit mailing destination published in the current public MESA directory.

The current public MESA Contact Us directory explicitly labels this fax Pharmacy Prior Authorization and separately publishes the ProDUR/Pharmacy PA Unit mailing address. The general provider fax, general office street address and general provider/EDI emails are different purposes. No PA-unit staffed hours or email is established by this directory. The linked MESA provider homepage announces that pharmacy PA requests submitted by fax will no longer be accepted effective January 1, 2027, when electronic submission through the MESA Provider Portal becomes required.
