UMP Preferred Drug List

Use the UMP Preferred Drug List (PDL) to find:

The UMP Preferred Drug List is updated at least monthly, and changes are posted online.

Not all drugs are listed on the UMP Preferred Drug List. If your drug is not listed, call Washington State Rx Services at 1-888-361-1611 (TRS: 711).

Note: New brand-name drugs may not be covered during the first 180 days they are available. To check if a new drug is covered, call Washington State Rx Services at 1-888-361-1611 (TRS: 711).

How does UMP decide which drugs are preferred?

As a state-sponsored health plan, UMP must follow coverage decisions made by the Washington State Pharmacy & Therapeutics Committee (P&T Committee), which consists of Washington health care professionals, including physicians and pharmacists. The UMP Preferred Drug List includes these coverage recommendations.

Not all drug classes are reviewed by the Washington State P&T Committee. For these drugs, the Washington State Rx Services P&T Committee makes coverage recommendations for UMP's review and final determination of a drug's coverage level (preferred or nonpreferred).

For the plan to approve a drug for you, it must be medically necessary for your health condition. Your provider may prescribe a drug or drug dose that is not medically necessary.

For more information on the P&T Committee, see the Prescription Drug Program's webpages.
