What is Medicare and what does it cover?

Medicare is the federal health insurance program for people who are 65 or older, or those under 65 who may qualify because of a disability or another special situation. Medicare helps millions of American seniors and disabled individuals cover some of their health care costs.

Medicare also offers important choices in how you receive benefits – whether through Original Medicare or through a Medicare-approved private insurer that offers prescription drug coverage and additional benefits like vision, hearing, dental, and more.

The different parts of Medicare help cover the costs of specific services.
