Find a network pharmacy

Retail network pharmacies

UMP has a large network of retail pharmacies, including independent, regional, and national chains. You save money when you use network pharmacies; you pay only your cost share. 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 prescription drug deductible or prescription drug out-of-pocket limit.

Find network and Choice90 retail 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 Choice90 pharmacy or Postal Prescription Services (PPS) mail-order pharmacy. To find one, search for a network pharmacy or call Washington State Rx Services at 1-888-361-1611.

Mail-order pharmacy

You may choose to use Postal Prescription Services (PPS), the network mail-order pharmacy, for convenient delivery of your prescriptions to your home or office, with no shipping charges. PPS accepts credit and debit cards, checks, or your Flexible Spending Account (FSA) Debit Card.

If you want to use PPS, you must create an account. PPS needs your medical history and payment information before you can fill prescriptions through mail order.

Set up your mail-order account

Do one of the following to set up your PPS account:

  • Create an online account with PPS.
  • Call PPS at 1-800-552-6694. You'll need to provide your insurance information, payment method, and medical history to set up an account.
  • Have your doctor fax a mail-order form along with your prescription. Only providers can do this. The prescription must:
    • Be faxed from your provider's office 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.

Log in to your mail-order account

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

Placing an order

To order a new prescription

  • Have your doctor fax it in. (See above.)
  • Send a form by mail.

To order refills

Refilling prescriptions you originally got elsewhere

You will need to give PPS more information, such as the prescription number, drug name, and the name and location of the pharmacy that originally filled the drug.
