When Can I Change My Medicare Plan? Key Dates to Remember

Medicare isn't a set-it-and-forget-it decision. Several times a year you get the chance to review and change your coverage β€” but only during specific windows.

Annual Enrollment Period (Oct 15 – Dec 7)

This is the big one. You can switch between Original Medicare and Medicare Advantage, change drug plans, or join a plan for the first time.

Medicare Advantage Open Enrollment (Jan 1 – Mar 31)

Already in an Advantage plan? You get one chance to switch to another Advantage plan or return to Original Medicare.

Special Enrollment Periods

Life events like moving or losing employer coverage can open a personal window. We help you track every date so you never miss one.
