Prescription Drug Programs

Prime Therapeutics is your Pharmacy Benefit Manager (PBM) as of March 1, 2019.


Prime Therapeutics maintains the Balanced Drug List (also known as a prescription drug list) and manages a network of retail pharmacies.

The Balanced Drug List is a list of drugs available to Blue Cross and Blue Shield of Illinois (BCBSIL) members. How much you pay out-of-pocket for prescription drugs is determined by whether your medication is on the list and the tier designation of the drug.  Generally, if you choose a drug that is generic or preferred, your out-of-pocket costs will be less. Your doctor should consult the Balanced Drug List when prescribing drugs for you. This list is regularly updated as generic drugs become available and changes take place in the pharmaceuticals market.


Most major chain pharmacies participate in the Prime network except CVS pharmacies. If you are using an independent drugstore, you should confirm whether it participates in the network. To find out, visit or call a Benefits Value Advisor (BVA) Customer Service Representative at 855-686-8517.
