Prescription price check tool or UMP Preferred Drug List?

Use the prescription price check tool if you are looking mostly for 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.

You can search the UMP Preferred Drug List by drug name or by drug class (for example, cardiovascular drugs). If you know of one particular drug, 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 the tier of a drug before you fill a prescription, especially for a new drug. You may also call Washington State Rx Services at 1-888-361-1611 to check the tier level of a drug.
