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, like whether 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 is updated often. 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 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.

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.
