Prescription Drug List 

BCBSIL pharmacy benefits include a list of preferred drugs (formulary) selected by BCBSIL based on clinical recommendations of the Prime Therapeutics National Pharmacy and Therapeutics committee. Drugs are recommended for addition to the Drug Lists after considering safety, efficacy, uniqueness, and cost. Physicians are encouraged to prescribe drugs in this list.

Pharmacy Finder

Members can search the online pharmacy directory to find a participating pharmacy near their home or office. Or, they can search for a pharmacy by name or ZIP code.

Mail Order Prescriptions

Members currently enrolled in the PrimeMail prescription drug program can submit refills online or by calling 1-833-715-0942. The service is available 24 hours-a-day, seven days-a-week, to refill, transfer a current prescription or get started with home delivery.

Some HMOs offer a 90-day supply benefit that can save time and money. With this program, members have the option of obtaining up to a 90-day supply of long-term (or maintenance) medications. The 90-day supply program is an option when using Prime's mail-order delivery.

Prior Authorization/Step Therapy Programs

The prior authorization/step therapy program is designed to encourage safe, cost-effective medication use. Most standard products plans include this program. Self-insured and custom fully insured groups offer a variety of these programs to help effectively manage their prescription drug benefit.

Pharmacy Benefits Tier Design Program

Your client's plan may include three-tier or four-tier pharmacy coinsurance and copay plan designs. These plan designs offer your client the opportunity to save money by choosing prescription medications that are less costly but equally effective. The plan designs retain freedom of choice because benefits will still be available for nearly all branded prescription drugs.

Women's Contraceptive Services

Our plans may cover certain contraceptive coverage as a benefit of membership. Coverage can vary depending on the type of plan enrolled in.
