Medicare is the federal health insurance program for people 65 and older, some younger people with disabilities, and people with end-stage renal disease. If you're turning 65, already on Medicare, or helping someone understand their coverage, you likely have questions about how the program works, what it covers, and what it costs. This section addresses the questions that come up most often.
You'll find information about the different parts of Medicare, how to sign up, what happens if you miss a important date, and how Medicare works with other insurance. These articles explain coverage details, costs like premiums and deductibles, and how to handle common situations like changing plans or using Medicare while traveling.
