What We Cover

The drugs we cover are listed in our formulary. The drugs are chosen by a Pharmacy and Therapeutics Committee, which is made up of local providers and pharmacists. Community Health Plan of Washington and the Washington State Health Care Authority decide which drugs to cover based on medical studies and research and the needs of members. All of the drugs in our formulary are FDA approved. You will need Adobe Acrobat to read the PDFs. Download it for free.

Personal Medication Coach Program

The Personal Medication Coach Program helps member who are managing more than one medical issue and are taking multiple medications. We partner with SinfoniaRx to work with you and your doctors and make sure your medications are working to improve your health.

You can learn more about this program by visiting sinfoniarx.com or calling 1-844-866-3730.

Prior Authorization

Some drugs require prior authorization, which means Community Health Plan of Washington has to review and approve coverage before we can help you pay for them. You can check whether your medicine needs prior authorization or has any coverage restrictions by calling Customer Service or checking our formulary.

Your provider is in charge of submitting prior authorization requests for your medication.

Uncovered Prescriptions

If you need medicine that isn’t listed on our formulary, you can request a coverage determination review through Customer Service.

If your coverage is denied by Express Scripts, you can appeal the decision with Community Health Plan of Washington. Read about how to appeal or file a grievance.

If you paid full price for a prescription at a retail pharmacy, you can ask for a reimbursement. Check the formulary to make sure there were no restrictions on your medication before you ask to be reimbursed. Fill out a reimbursement form and either fax or mail it to Express Scripts. 

Find a Pharmacy

We have an extensive network of pharmacies across Washington, Oregon, Idaho, and Montana. Many of our Community Health Centers have their own pharmacies. To find the pharmacy closest to you, you can:

Be sure to bring your Community Health Plan of Washington ID card when you pick up your prescription. If you don’t have your card, you can log in to your myCHPW account to view, download, and print a copy of it.

Some complex or chronic illnesses need specialty drugs that require a higher level of service or care. Our specialty drugs are covered when they are dispensed through Accredo Specialty Pharmacy or participating Community Health Center pharmacies. Check our formulary for your specialty drug and ask your local Community Health Center if their pharmacy supplies your medication.

Find your local Community Health Center.

If you’re traveling outside of our coverage area, please contact us. Usually, prescriptions filled outside of our network aren’t covered. Pharmacies can dispense up to a 72 hour supply of a medication in an emergency.
