The formulary is comprised of generic, brand name and specialty drugs, including Preferred drugs, that when selected will lower your out-of-pocket costs. Drugs on the formulary are assigned to a tier. Your cost-share/copay will depend on the tier in which your drug resides. Formulary placement decisions are based on recommendations by the Pharmacy and Medical Policy Committee (PMPC) – an independent group of practicing physicians and pharmacists. You can view a list on our Formulary page.
