How does UMP decide which drugs are preferred?
As a state-sponsored health plan, UMP must follow coverage recommendations 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.
