What is Medicare

A Simple Guide for Beginners

If you’re turning 65 or helping a loved one, you’ve probably heard of Medicare. But with so many parts and options, it can be confusing. This guide breaks it down into simple terms so you can make informed decisions.


 

Understanding the 4 Parts of Medicare

Before we get into all the parts of Medicare, let’s start with the foundation: Original Medicare.

What Is Original Medicare?

Original Medicare is made up of Part A and Part B, and it’s provided directly by the federal government.

 

  • Part A – Hospital Insurance
    Covers inpatient hospital stays, skilled nursing facility care, hospice services, and some limited home health care. Most people don’t pay a premium for Part A if they’ve worked and paid Medicare taxes for at least 10 years.

  • Part B – Medical Insurance
    Part B helps cover services like doctor visits, outpatient care, preventive services, lab tests, and medical equipment. Most people pay a monthly premium for Part B, which is adjusted based on income.

 

Together, Parts A and B form the backbone of Medicare and cover many common healthcare needs — but not all of them. That’s where Part C and Part D come in.

Part BDoctor visits, outpatient care, medical equipment
Part CAll-in-one Medicare Advantage plans (may include A, B, D, plus extras)
Part DPrescription drug coverage

 

What Medicare Doesn’t Cover

Original Medicare covers a lot — but not everything. Common exclusions include:

  • Dental care

  • Vision services and eyeglasses

  • Hearing exams and hearing aids

  • Prescription drugs (unless enrolled in Part D)

  • Long-term custodial care

  • Care outside the U.S. (except some emergencies)

✉️ This is why many people look for extra coverage.

How to Fill the Gaps in Coverage

Once you have Parts A and B (Original Medicare), you typically choose one of two paths:

 

Option 1: Add a Medicare Supplement (Medigap) + Part D

  • Helps pay deductibles, coinsurance, and copays.

  • Lets you see any doctor who accepts Medicare.

  • Requires separate Part D for prescriptions.

 

Option 2: Enroll in a Medicare Advantage (Part C) Plan

  • Bundles A & B (and often D) into one private plan.

  • May include dental, vision, hearing, and fitness perks.

  • Includes a max out-of-pocket limit for the year.
