The Medicare Open Enrollment period runs from October 15 through December 7 each year. During this period, people on Medicare can make a change in their coverage. If you are covered by Medicare, and you are interested in reviewing and comparing your Medicare coverage options, make sure the plans you are considering during the Medicare Open Enrollment period are Medicare plans, not Marketplace plans. Medicare plans are not sold through the federal or state Marketplace websites. You can review and compare your Medicare options on the Medicare coverage comparison website, a searchable tool on the Medicare.gov website, or by calling 1-800-MEDICARE (1-800-633-4227). You can also contact the State Health Insurance Assistance Program (SHIP) in your state. SHIPs offer local, personalized counseling and assistance to people with Medicare and their families. You can call 877-839-2675 to get the phone number for the SHIP in your state.
