For 2023 coverage, put these enrollment opportunities on your calendar:
The annual Medicare Advantage open enrollment period for Americans already enrolled in Medicare Advantage will start January 1, 2023 and continue through March 31, 2023. If you’re enrolled in Medicare Advantage at the start of 2023 (even if you just picked a plan in the fall and it started January 1), you can switch to a different Advantage plan or switch to Original Medicare during the first quarter of 2022.
General enrollment for Medicare Part B starts January 1 and continues through March 31. (This window also applies to Part A, if you have to pay a premium for it and didn’t sign up when you were first eligible). If you sign up for Part B (or Part A, if applicable) during this window, your coverage will start the first of the following month (the start date used to be July 1, but that has changed as of 2023).
Medicare open enrollment – the annual election period – for 2024 coverage runs from October 15, 2023 to December 7, 2023. This window provides the most plan change flexibility, allowing beneficiaries to make changes to their Medicare Advantage or Part D plans, switch from Original Medicare to Medicare Advantage or vice versa, or sign up for Part D if they didn’t do so when they were first eligible (a late enrollment penalty may apply).
