Prescription Coverage

Your copayment summary will help you determine whether your prescription coverage uses the three or four-tier plan. It is important to note that prescription coverage may be subject to pharmaceutical management (for example, prior authorization). Additionally, there are a small number of drugs, regardless of tier, that may require prior authorization to ensure appropriate use.

Three-tier Plan

  1. Preferred generic medications listed on the Preferred Drug List are covered at the lowest tier copayment level
  2. Preferred brand name medications listed on the Preferred Drug List are provided at the second-tier copayment level
  3. Non-preferred drugs listed on the Preferred Drug List are covered at the third-tier copayment level

Unique cost shares apply for self-injectable medications, and medications for the treatment of infertility (if covered) and erectile dysfunction (see copayment summary)

Four-tier Plan

  1. Preferred generic medications listed on the Preferred Drug List are covered at the lowest tier copayment level
  2. Preferred brand name medications listed on the Preferred Drug List are provided at the second tier copayment level
  3. Non-preferred drugs listed on the Preferred Drug List are covered at the third tier copayment level
  4. Specialty medications are covered at the fourth tier copayment level

Prescription Costs

Not all medical plans have prescription coverage. If you have 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

  1. Use WHA's prescription drug search to find the medication listed on the Preferred Drug List
  2. Identify the medication's tier
  3. Refer to your copayment summary for the copayment that is associated with that tier

Deductible Plans

  1. Refer to your copayment summary to determine if prescriptions are subject to a deductible on your plan
  2. Use OptumRx's pricing tool to price a prescription medication under the deductible.
  3. Once your deductible has been met, refer to the instructions for copay plans to determine your share of costs
