On drugs required for certain medical conditions, prior approval may be needed before the prescription is covered. Learn more about situations where prior approval is required.
Some drugs are part of the Premera Pharmacy Pre-approval Program. Medications for certain conditions - such as migraines, diabetes, high blood pressure or asthma - may need to meet certain requirements before a prescription is covered.
Go to the Pharmacy Pre-approval Drugs accordion to see if the drug requires this type of pre-service review.
When a prescription is filled at the pharmacy, the prescription is checked to see if it meets recommended guidelines:
The member or the pharmacy can call the member's provider with notification that a pharmacy Pre-approval is needed for the drug. The member's provider will need to contact our Pharmacy Services Center to request review.
Once we receive the provider's information, our review process takes one to two business days. We'll then send the member a letter confirming the decision made about the member's prescription coverage. We'll also fax the decision to the member's provider.
Type in the name of the drug for details about prior authorization criteria, and medical policies.
Note: This list shows drugs that require pharmacy pre-approval that are common to all plans.
To find out if your medicine requires pharmacy pre-approval, log in and access Express Scripts via your Pharmacy Services page.
