Medicare Advantage
One plan from a private insurer that replaces how you get Part A and Part B, usually adds drug coverage, and caps what you pay out of pocket in a year. You use the plan network.
Medicare made clear
What each part actually covers, how Medicare Advantage and Medigap differ, and which enrollment window applies to you. Then see the plans offered in your county.

Annual Enrollment: October 15 to December 7This is the window when anyone with Medicare can join, switch, or drop a Medicare Advantage or Part D plan. Changes you make take effect on January 1. If you are new to Medicare, your own Initial Enrollment Period around your 65th birthday comes first.
