Changes Coming to 2020 Formulary

On January 1, 2020, all managed care plans and Apple Health fee-for-service programs will continue to phase in a Single Preferred Drug List (PDL).

This change is mandated by the Washington State Legislature.

The Health Care Authority is working with managed care plans that serve Apple Health clients to create the Apple Health PDL. Managed-care plans will continue to use their own preferred drug lists for drugs not included in the Apple Health PDL.

Please contact with any questions.

Prior Authorization

To request a prior authorization, step therapy, nonformulary, or quantity limit override, please call ESI at 1-844-605-8168, 24 hours a day, 7 days a week, and speak to a prior authorization service specialist. This specialist will review medical information and criteria with the provider or designee regarding the need for the requested drug.

Any pharmaceutical not listed on our formulary requires prior authorization. For self-administered drugs requiring prior authorization, please contact Express Scripts at 1-844-605-8168 or use to start the prior authorization process.

You can submit a request for a coverage determination review by sending in a Coverage Determination Request form or filling out the online form.

Pharmacy Reimbursement Issues

If you are having an issue with reimbursement, please submit an inquiry to ESI through their Pharmacist Resource Center.

Pharmacy Emergency Fills

Emergency fills may be covered to prevent interruptions in therapy during an emergency. View our policy on emergency fills.
