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:
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.

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.
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.

Age 65 represents a huge milestone for most Americans—it’s the age when a majority of people become eligible for Medicare. But becoming eligible for Medicare and enrolling in Medicare are two separate things. Most people must manually join Medicare during one of their enrollment periods once they’re eligible. Unfortunately, this information doesn’t seem to be widespread knowledge.
According to a recent survey, 41% of Americans 54 and up—the age group nearest to Medicare benefits—think they’ll automatically be enrolled in the government health plan once they’re eligible. Let’s nip this myth in the bud.
You need to enroll in Medicare yourself unless you fall into one of these groups:
- You’ve been collecting Social Security disability benefits for 24 months.
- You have ALS (Lou Gehrig’s disease) or ESRD (end-stage renal disease).
- You’re already receiving Social Security benefits before age 65.
For everyone not on this list, it’s critical to sign up at the right time! Not doing so will result in late enrollment penalties—some of which may last for the rest of your life.
Medicare late enrollment penalties
Did that get your attention?
To avoid late penalties, most should sign up for Medicare during their Initial Enrollment Period (IEP). This period begins three months before your 65th birthday month and lasts until three months after the month you turn 65—seven months total. For example, if you turn 65 on August 5, your IEP lasts from May 1 to November 30.
What about those who work past 65 and are still covered by an employer’s health plan?
No worries, you can delay Medicare enrollment without penalty if you’re in a qualified health plan (just talk to your HR representative to be sure it’s qualified). If you’re in an employer’s health plan, you may enroll in Medicare anytime after age 65. You also get a Special Enrollment Period (SEP) after your employer coverage ends to sign up for Medicare. Your SEP lasts for eight months once employer coverage stops.
There are several other enrollment periods as well, each designed for people in specific situations.
Learn more about Medicare enrollment periods.
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.
