Find prescription drugs and network pharmacies 

Alert: Walgreens, a non-network pharmacy, recently bought many Rite Aid locations. Those locations are no longer in your UMP pharmacy network. However, all Rite Aids in Washington and Oregon are still in the UMP pharmacy network. 

The pharmacy locator has not yet been updated to reflect this change, so please call Washington State Rx Services at 1-888-361-1611 (TRS: 711) to make sure a Rite Aid location outside Washington or Oregon is still a network pharmacy.

Use Sam's Club to fill your prescriptions? Make sure your network pharmacy is still available.

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

Find vaccinating pharmacies

Network vaccination pharmacies give preventive immunizations at no cost to you. Not all network pharmacies offer vaccinations, so call the pharmacy before you go. You can also visit your preferred provider (network provider for UMP Plus) or a public health department to get vaccinated. However, if you go to a public health department, you usually have to pay and get reimbursed later by submitting a medical claim form.

To find out which immunizations are considered preventive, read the Centers for Disease Control (CDC) immunization schedules. Note that some are classified as “may be recommended” depending on medical condition or lifestyle. For those immunizations to be covered as preventive, you must meet the criteria described on the CDC schedule.

    If you get a vaccine from an out-of-network provider, you must submit a medical claim form.  You will pay 40 percent coinsurance and the provider may balance bill you.

    Tip: Not all pharmacies have all vaccines. Call the pharmacy ahead of time to make sure it has the one you need.
