UMP Preferred Drug List (PDL)

Find out the tier of a drug or whether a drug is specialty, requires preauthorization, is subject to other limits, or has less expensive alternatives.

  • The UMP PDL may be updated at any time. Changes are posted online at least once a month. Be sure to check the tier of a drug before you fill a prescription, especially for a new drug, by using the UMP PDL or by calling Washington State Rx Services at 1-888-361-1611.
  • Not all drugs are listed in the UMP PDL. If your drug isn't listed, call 1-888-361-1611.
