Medicare is the federal health insurance program for people 65 and older, regardless of income or health history. It also covers some younger people with disabilities and those with end-stage renal disease. Understanding how Medicare works—what it covers, what it costs, and when you can sign up—matters because the choices you make affect your out-of-pocket expenses and access to doctors and hospitals.
These articles explain the different parts of Medicare, how to compare plans, what happens if you miss enrollment important date, and how Medicare works with other insurance you might have. You'll find information about prescription drug coverage, costs like premiums and deductibles, and how to handle claims and appeals when coverage questions come up.
