Prescription drugs

Quick find

Note: To make sure you pay the right amount for your prescriptions, always show your UMP ID card first. If you have a prescription drug discount card, show that card second to see if you can get a discount on prescriptions UMP does not cover.

Prescription price check or UMP Preferred Drug List?

Use the prescription price check if you want to know how much your drug will cost. To get information specific to your account (for example, if you've met your deductible), log in to your pharmacy account and use the prescription price check tool.

The UMP Preferred Drug List is a better bet if you are looking for the following:

Note: The UMP Preferred Drug List may be updated at any time. Changes are posted online at least once a month. However, not all drugs are listed on the UMP Preferred Drug List. If your drug isn't listed, call Washington State Rx Services at 1-888-361-1611.

You can search the UMP Preferred Drug List by drug name or by drug class (for example, cardiovascular drugs). If you know one drug's name, you can search for it by name and note the drug class. Then you can find similar drugs by searching for that class.

Be sure to check a drug's tier before you fill a prescription, especially for a new drug, by using the UMP Preferred Drug List or calling Washington State Rx Services at 1-888-361-1611.
