Medicare Made Simple: What You Need to Know About Parts A, B, C & D

When people hear “Medicare,” they often think it’s a single, one-size-fits-all plan. But Medicare is actually a group of distinct coverage options—each one designed to help with specific healthcare needs. Before you enroll, it's important to understand how each part works so you can choose the coverage that fits your life and budget.

What Is Medicare?

Medicare is a federal health insurance program for:

  • People aged 65 and older

  • Individuals under 65 with certain disabilities

  • People with End-Stage Renal Disease (ESRD) or ALS (Lou Gehrig’s disease)

While Medicare helps cover many essential healthcare services, it doesn’t cover everything. That’s why knowing the difference between each part—A, B, C, and D—is essential.

Breaking Down the 4 Parts of Medicare

Part A – Hospital Insurance

Part A helps cover:

  • Inpatient hospital stays

  • Skilled nursing facility care

  • Hospice services

  • Some home health care

Cost: Most people don't pay a premium for Part A if they (or their spouse) paid Medicare taxes during their working years.

Part B – Medical Insurance

Part B covers:

  • Doctor visits

  • Outpatient care

  • Durable medical equipment

  • Preventive services like screenings and vaccines

Cost: You’ll typically pay a monthly premium for Part B coverage.

📌 Original Medicare = Part A + Part B, both managed by the federal government.

Part C – Medicare Advantage Plans

Part C, also known as Medicare Advantage, is a bundled plan offered by private insurance companies approved by Medicare. These plans often include:

  • Part A and B benefits

  • Part D prescription drug coverage

  • Extra perks may be available

Choosing a Medicare Advantage plan can provide all-in-one convenience and added value beyond what Original Medicare offers.

Part D – Prescription Drug Coverage

Part D helps pay for prescription medications and is available through private insurers.

Important: If you don’t enroll in Part D when you’re first eligible, you may have to pay a late enrollment penalty later.

Navigating Medicare doesn’t have to be overwhelming. Start by understanding the basics of Parts A, B, C, and D—then explore the options that match your personal healthcare needs and budget.
