Medicare has a few doors, not one. The Initial Enrollment Period sits around your 65th birthday. The fall Annual Enrollment Period is the usual window to change Advantage or Part D. Some people have a trial right or a Special Enrollment Period after a move or a loss of coverage.
Dates are federal and they shift slightly by year. This page does not list every exception. Call your licensed agent with your birthday, your current plan, and any employer coverage.
FAQ
Short answers you can use on a call with your agent.
Is October 15 the only time I can change?
No. Annual Enrollment is one door. Initial enrollment, some trial rights, and Special Enrollment Periods are others. Your licensed agent maps the date that applies to you.
