The UMP website is moving. This website contains 2019 UMP information for PEBB members only (through the end of 2019). If you are a PEBB member and/or you will be a new School Employees Benefits Board (SEBB) member and you need 2020 UMP benefits information, visit our new UMP website.

Allowed amount, prescription drugs

The allowed amount for prescription drugs is based on Washington State Rx Services’ (WSRxS) contractually agreed reimbursement, unless other contractual arrangements or terms apply. All covered prescription drug claims are paid based on this allowed amount.
