Guides

Medicare guides in plain English

What Medicare Parts A, B, C and D cover, how Original Medicare and Medicare Advantage differ, and what you can change during fall Open Enrollment.

Golden Third Chapter editors · Updated October 2026

These guides explain how Medicare works. They don't sell anything, don't name insurance companies and don't recommend any plan. They're here so you can understand your own coverage before you decide anything — or talk to anyone.
