When I read about Medicare Part D, I keep seeing the word "formulary". What does it mean?


A formulary is a list of prescription drugs that are covered by a Medicare Part D plan. Drugs listed on the formulary are sometimes called "eligible drugs." A formulary may also be called a "preferred-drug list" (PDL) or a "select drug list."

Each plan has its own formulary. All formularies are similar because they're based on federal guidelines, but they may not include exactly the same drugs. The differences may be important to you because you will want the drugs you take to be on your plan's list. Be sure to compare formularies when you select a plan. This information will be available through each plan's web site, customer service center, and through marketing materials.
