A formulary is a list of covered drugs provided by a plan. Formularies may vary from plan to plan and the list of covered drugs can change from year to year. It’s a good idea to find out if your medications are covered before you join a plan or want to switch plans during the Annual Open Enrollment Period. You can usually review enrollment materials like the formulary online, call Customer Service, or request a formulary be mailed to you.

If you are taking prescription medications to manage a chronic condition such as heart disease, hypertension, high cholesterol or diabetes, always remember to check that the drugs you are taking are included in your plan’s formulary—that can save you a lot of money down the road!
