Prescription list (formulary)

CareOregon Advantage covers a wide range of prescription drugs through Medicare Part D

To find out if your prescriptions are covered, search through our approved drug list, also known as our formulary.

• Click on the formulary you want to access.
• If you are accessing a PDF file, press Ctrl+F (PC) or ⌘-F (Mac) to open a search bar in the top right of your screen.
• Type the name of the medication into that search bar and press enter.
• If there are multiple similar results, you can use the Previous and Next buttons to look for the correct medication.
• To search for more, simply type the next medication into the search bar and continue until you have found all your prescriptions.
• If your drugs are not on the list, go to the Medicare Part D Coverage Determinations, Formulary Exceptions and Appeals section for more information on how to ask for an exception.

If you still need help, you can always call Customer Service at 503-416-4279, toll-free 888-712-3258 or TTY 711. Our hours are October 1 through March 31, 8 a.m. to 8 p.m. daily; and April 1 through September 30, 8 a.m. to 8 p.m., Monday-Friday.
