What is Medicare?
Medicare is a U.S. federal health insurance program mainly for people 65 years and older, under 65 with certain disabilities, or people with End-Stage Renal Disease (ESRD) or ALS. It helps cover medical costs, though it doesn’t pay for everything.
Parts of Medicare

Part A – Hospital Insurance
- Covers inpatient hospital stays, skilled nursing facilities, hospice, and some home health care.
- Usually free if you (or your spouse) paid Medicare taxes while working.
Part B – Medical Insurance
- Covers doctor visits, outpatient care, preventive services, and some home health care.
- You pay a monthly premium.
Part C – Medicare Advantage (Private insurance alternative)
- Run by private companies approved by Medicare.
- Combines Part A + Part B, often includes prescription drug coverage (Part D) and extras like vision or dental.
- Usually has a provider network (like an HMO or PPO).
Part D – Prescription Drug Coverage
- Helps cover the cost of prescription medications.
- Offered through private plans approved by Medicare.

What Medicare Does Not Fully Cover
- Long-term care (nursing homes beyond skilled care)
- Most dental, vision, and hearing services
- Cosmetic surgery
- Routine foot care
(That’s why many people buy Medigap supplemental insurance to fill coverage gaps.)
