Formulary Overview
A formulary is a list of covered drugs under a Medicare Advantage Part D Plan. The list includes both brand-name and generic drugs. We have a team of doctors and pharmacists—our Pharmacy and Therapeutics Committee (P&T)—who review our formulary for safety and effectiveness. Based on recommendations from our P&T Committee, we occasionally make changes to the medications covered by our formulary.
Medications on the formulary may change
Most changes in drug coverage happen on January 1, but we may add or remove drugs on the drug list during the year, move them to different cost-sharing tiers, or add new restrictions. We must follow Medicare rules in making these changes.
