Find a network pharmacy

Retail network pharmacies

UMP has a large network of retail pharmacies. You save money when you use network pharmacies, and the pharmacy sends the claim to the plan for you.

If you use a non-network pharmacy, you will pay the entire cost of the drug and must submit a claim. Only the allowed amount for covered drugs will count toward your deductible or out-of-pocket limit.

Some, but not all, network pharmacies offer preventive immunizations. Visit the Find drugs page to learn more about vaccinating pharmacies.

Find network pharmacies

Tip: If you take an ongoing prescription drug and purchase between an 84- to 90-day supply, you may be able to save money by using a Choice90Rx pharmacy or the UMP mail-order pharmacy. To find one, search for a network pharmacy (above) or call Washington State Rx Services at 1-888-361-1611.

Mail-order pharmacy

You may use Postal Prescription Services (PPS), the network mail-order pharmacy, for convenient delivery to your home or office, with no shipping charges. 

Prescriptions are usually delivered within 7 to 10 days after the pharmacy receives your prescription. When using PPS, the same deductible, coinsurance, preauthorization requirements, and limits on coverage apply as for prescription drugs purchased at retail network pharmacies.

If you want to use PPS, you must create an account.

Set up your mail-order account

  1. Set up an account with PPS online or call PPS at 1-800-552-6694.
  2. Mail your prescription to PPS. Your provider can also electronically send or fax your prescription to PPS. Prescriptions faxed to PPS must:
    • Be faxed from your provider's office fax machine to 1-800-723-9023 (fax number for providers only).
    • Be on the provider's letterhead.
    • Include the patient's name, address, phone number, plan ID number, and date of birth.

Note: Only a provider can fax in a prescription. You must follow these instructions to avoid a delay in filling your prescription.

Alert: Some durable medical equipment (DME) items are not available through PPS. You will need to get them through a network retail pharmacy or preferred DME provider.
