What Is Medicare?

Medicare is a federal health insurance program designed to provide affordable healthcare coverage for individuals who are 65 and older, as well as certain younger individuals with qualifying disabilities or medical conditions.

Understanding how Medicare works — and which options are available — is essential to making informed healthcare decisions that protect both your health and your finances. This guide will walk you through the fundamentals of Medicare and explain the four main parts: Part A, Part B, Part C, and Part D.

Medicare Fundamentals – The Basics You Need to Know

Medicare is divided into different parts, each covering specific healthcare services. Some parts are provided directly by the federal government, while others are offered through private insurance companies approved by Medicare.

Who Is Eligible for Medicare?

You may qualify for Medicare if you:

• Are 65 or older

• Have received Social Security Disability benefits for at least 24 months

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

When Can You Enroll?

Most people enroll during their Initial Enrollment Period (IEP) — a 7-month window that includes:

• 3 months before your 65th birthday month

• Your birthday month

• 3 months after

There are also Annual Enrollment Periods (AEP) and Special Enrollment Periods (SEP) that allow plan changes at certain times.

Medicare Part A – Hospital Insurance

Medicare Part A primarily covers inpatient hospital care and facility-based services.

What Does Part A Cover?

• Inpatient hospital stays

• Skilled nursing facility care (after a qualifying hospital stay)

• Hospice care

• Limited home health care

How Much Does Part A Cost?

Most people do not pay a monthly premium for Part A if they or their spouse worked and paid Medicare taxes for at least 10 years (40 quarters).

However, Part A does include:

• Deductibles

• Daily coinsurance for longer hospital stays

Medicare Part B – Medical Insurance

Medicare Part B covers doctor services and outpatient medical care.

What Does Part B Cover?

• Doctor visits

• Preventive services

• Outpatient care

• Lab tests and diagnostic screenings

• Durable medical equipment (DME)

• Mental health services

• Ambulance services (when medically necessary)

How Much Does Part B Cost?

Part B has:

• A monthly premium (set annually by Medicare)

• An annual deductible

• Typically 20% coinsurance after the deductible

Medicare Part C – Medicare Advantage Plans

Medicare Part C, also known as Medicare Advantage, is an alternative way to receive your Medicare benefits through private insurance companies approved by Medicare.

How Does Medicare Advantage Work?

Medicare Advantage plans bundle:

• Part A (hospital)

• Part B (medical)

• Often Part D (prescription drug coverage)

Many plans also include valuable extra benefits that Original Medicare does not cover.

Common Medicare Advantage Benefits:

• Prescription drug coverage

• Dental

• Vision

• Hearing

• Fitness memberships

• Over-the-counter (OTC) allowances

• Transportation benefits

• Meal programs

Why Do Many People Choose Medicare Advantage?

• All-in-one coverage

• Predictable costs

• Extra benefits

• Low or $0 monthly plan premiums (depending on location and plan)

Medicare Part D – Prescription Drug Coverage

Medicare Part D provides prescription drug coverage through private insurance carriers.

What Does Part D Cover?

• Brand-name medications

• Generic medications

• Vaccines

• Certain specialty drugs

Each plan has its own formulary (drug list) and pharmacy network.

Why Is Part D Important?

Without credible prescription drug coverage, you may face:

• Late enrollment penalties

• Higher long-term costs

• Limited medication access
