Prescription Coverage
2025 Plans - WHA is transitioning its prescription drug benefits to a Premium Formulary and Essential Health Benefits Formulary effective January 1, 2025. This is a proactive move for WHA to bend the trend of managing prescription costs more effectively for our members, while also maintaining accessibility to necessary medications. WHA is a health plan built on access and affordability. With this move, we’ve developed the right balance in our Pharmacy Benefits with OptumRx, enabling us to maintain options selected for clinical effectiveness, while still providing access to affordable medications and lower-cost alternatives. This also allows WHA to remain aligned with industry best practices and trends. Learn more by visiting the 2025 Formulary resources page here.

Prescription Costs
For plans with prescription coverage, you will pay the lesser of the retail price, or cost sharing as described below, for any prescription, retail or mail order. Refer to your copayment summary for additional details.
Copay Plans
- Use WHA's prescription drug search to find the medication listed on the Preferred Drug List
- Identify the medication's tier
- Refer to your copayment summary for the copayment that is associated with that tier
Deductible Plans
- Refer to your copayment summary to determine if prescriptions are subject to a deductible on your plan
- Use OptumRx's pricing tool to price a prescription medication under the deductible.
- Once your deductible has been met, refer to the instructions for copay plans to determine your share of costs
On January 1, 2025, the cost or coverage of your current medication may change. If you are currently taking appropriately prescribed medication and your health care provider continues to prescribe this medication for you, you may remain on this medication, in accordance with state law. However, the medication may be subject to placement on a different tier resulting in a change in cost sharing. Speak to your provider regarding medication options under the new formulary or visit our pharmacy website for more information.
