En español | You must first enroll in original Medicare and then switch into the separate Medicare Advantage program, which is an alternative to original Medicare.
You can review the Medicare Advantage plans sold in your area by using Medicare's online Plan Finder program at www.medicare.gov/find-a-plan/questions/home.aspx. For individual assistance, call Medicare at 800-633-4227 (TTY: 877-486-2048) or contact your local State Health Insurance Assistance Program (or SHIP) at 877-839-2675 or go to www.shiptacenter.org/.
If you are not joining Medicare for the first time, you have to wait until the annual open enrollment period from Oct. 15 through Dec. 7 in order to enroll in a Medicare Advantage plan. Your new coverage will begin Jan. 1 of the following year.
