Over 60 million Americans receive Medicare benefits,1 but many people don’t know how the program works, whether they’re eligible for Medicare, or how to apply. In a lot of ways, Medicare isn’t like the health insurance you may have had in the past, so at times it’s a little counterintuitive.

In this Medicare guide, we break down what you need to know about Medicare coverage so you can choose the right options for you. Here’s what we’ll go over:

What is Medicare?

Medicare helps people 65 and older and those with disabilities pay for their health care costs. The US government funds Medicare health insurance, and the Centers for Medicare & Medicaid Services (CMS) administer it.

Am I eligible for Medicare?

You can become eligible for Medicare in two ways:

  • Age: You’re 65 or older.
  • Disability: You’ve received disability benefits for 24 months, or you’ve been diagnosed with either end-stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS).

The Medicare program also has citizenship and other requirements.

What’s included in Medicare benefits?

Medicare has two primary parts: Part A (hospital insurance) and Part B (medical insurance). Together these parts form Original Medicare. Medicare recipients can add prescription drug coverage (Part D) or a Medicare Supplement plan or both. Or, you can choose Medicare Advantage (Part C), which covers everything Original Medicare does and more.

Currently, 38 million people have Original Medicare, and 22.6 million people have Medicare Advantage.2

Medicare Part A

Medicare Part A covers you if you become an inpatient in a hospital or skilled nursing facility. This insurance also covers hospice and some home health care services.

Medicare Part B

Medicare Part B covers more regular health care costs, such as doctor office visits, lab work, and durable medical equipment (such as medical braces or wheelchairs).

Medicare Part C

Also known as Medicare Advantage, Medicare Part C is something you choose in place of Parts A and B, and it includes everything Parts A and B cover in a single plan. Additionally, many Medicare Advantage plans also offer prescription drug coverage and services such as dental, vision, and hearing care. If you choose a Part C plan, you may also have access to the SilverSneakers fitness program.

Medicare Part D

Medicare Part D plans are stand-alone prescription drug plans designed to pair with Original Medicare (Parts A and B). Part D covers medications you take at home, while Parts A and B typically pay for prescriptions you receive at the hospital or in a doctor’s office, respectively.

Medicare Supplement (Medigap)

Medicare Supplement (Medigap) plans help cover the costs left behind by Medicare Parts A and B, such as deductibles and copayments. You must have Original Medicare (not Medicare Advantage) to enroll in a Medigap plan.

What does Medicare cost?

Each part of Medicare has a monthly premium you may have to pay to receive benefits, but many people avoid some of these premiums. If you’ve paid into Medicare taxes at work, for example, you may not have to pay for Part A. And, you could choose a Medicare Advantage or Part D plan that has a $0 premium if one is available in your area.

Most parts of Medicare also come with deductibles and other costs such as copayments and coinsurance.

When to enroll in Medicare

Generally, the best time to enroll in Medicare and avoid any Late Enrollment Penalties (LEPs) is when you’re first eligible. At that time, you’ll receive an Initial Enrollment Period (IEP) that begins three months before you’re eligible and ends seven months later.

Medicare Initial Enrollment Period

There are several other enrollment periods as well, each designed for people in specific situations.

Learn more about Medicare enrollment periods.

How to apply for Medicare

Each part of Medicare has different enrollment rules. If you want Part A and Part B, for example, you’ll apply through the Social Security Administration (SSA). Medicare Advantage, Part D, and Medicare Supplement plans are regulated by the government but provided by private companies. That means you’ll need to enroll with the companies that provide these plans.
