The UMP website is moving. This website contains 2019 UMP information for PEBB members only (through the end of 2019). If you are a PEBB member and/or you will be a new School Employees Benefits Board (SEBB) member and you need 2020 UMP benefits information, visit our new UMP website.

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, your prescription drug claims history), 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:

  • If a drug is covered by the plan.
  • How much you will pay for a drug based on the drug’s tier.
  • If the drug must be preauthorized​.
  • If the drug must be purchased from the plan’s specialty pharmacy, Ardon Health.
  • If there are any limits on a drug’s coverage.
  • If there are less expensive alternatives.

Changes to the UMP Preferred Drug list are posted online at least once a month. However, not all drugs are listed on the UMP Preferred Drug List. Also, a drug may change tiers at any time, particularly when a generic equivalent becomes available. New brand-name drugs may not be covered during the first 180 days they are available.

For questions about your prescription drugs, or to check if a new drug is covered, call Washington State Rx Services at 1-888-361-1611 (TRS: 711).

Note: When a generic equivalent for a brand-name drug becomes available, the brand-name drug immediately becomes Tier 3 (nonpreferred). Always ask your doctor to allow substitution on your prescriptions to save you money.
