Medicare Made Simple

Understanding the 4 Parts of Medicare

Medicare is easier to understand when you break it into four basic parts. Each part covers something different.

Medicare Part A Hospital Insurance

Part A

Hospital Insurance

Helps cover inpatient hospital care, skilled nursing facility care, hospice care, and certain home health services.

Medicare Part B Medical Insurance

Part B

Medical Insurance

Helps cover doctor visits, outpatient care, preventive services, medical equipment, and other medically necessary services.

Medicare Part C Medicare Advantage

Part C

Medicare Advantage

An alternative way to receive your Part A and Part B benefits through a Medicare-approved private insurance company. Many plans also include Part D prescription drug coverage and additional benefits.

Medicare Part D Prescription Drug Coverage

Part D

Prescription Drug Coverage

Helps cover prescription drugs you take at home. Part D plans are offered by private insurance companies approved by Medicare.

The easiest way to remember it: | A = Hospital | B = Doctors | C = Medicare Advantage | D = Prescription Drugs
Original Medicare

How Parts A & B Work Together

Original Medicare consists of Part A (Hospital Insurance) and Part B (Medical Insurance). Together, they cover a wide range of healthcare services, but they don’t cover everything.

Medicare

Part A + Part B

Original Medicare covers many healthcare services, but it generally does not cover all costs. You may still be responsible for deductibles, coinsurance, and copayments.

The Bottom Line

Part A and Part B give you a strong foundation, but most people need an additional solution to help with the out-of-pocket costs that Original Medicare doesn’t cover.

You Have Choices

There are different ways to help cover the costs that Original Medicare doesn’t pay. We’ll walk you through your options so you can choose what’s best for your health and your budget.

What Original Medicare Doesn't Cover

Original Medicare Covers a Lot.
But Not Everything.

Parts A and B provide a strong foundation, but there are important costs and services Original Medicare generally doesn't cover.

No annual out-of-pocket maximum

No Annual Out-of-Pocket Maximum

Original Medicare has no annual limit on what you might pay out of pocket for covered Part A and Part B services.

Medicare deductibles and coinsurance

Deductibles & Coinsurance

Original Medicare includes deductibles and cost sharing. For Part B services, you generally pay 20% of the Medicare-approved amount after meeting the Part B deductible.

Dental vision and hearing coverage

Routine Dental,
Vision & Hearing

Original Medicare generally does not cover routine dental care, routine eye exams for glasses, hearing exams, or hearing aids.

Prescription drug coverage

Most Prescription Drugs

Original Medicare generally does not cover prescription drugs you take at home. Drug coverage is usually obtained separately through Medicare Part D or included with many Medicare Advantage plans.

So How Do You Fill The Gaps

That’s where your Medicare choices come in. You can keep Original Medicare and add additional coverage, or choose a Medicare Advantage plan as another way to receive your Medicare benefits.

Your Medicare Options

Two Main Ways to Get Your Medicare Coverage
