Medicare Advantage (MA) open enrollment happens annually from January 1 through March 31. Coverage starts the first day of the month after your request to join a plan.
During Medicare Advantage (MA) open enrollment, you can also switch to another Medicare Advantage plan or to original Medicare. You can take either option with or without joining a Part D plan for prescription medication coverage.
If you have a Medicare Advantage plan and it’s not the open-enrollment period – the first 3 months of the year – you may be able to make changes if you qualify for a special enrollment period (SEP).
