What are the Parts of Medicare?

You have choices when selecting your Medicare coverage. Knowing the parts of Medicare will help you get the best coverage for you.

One of the more confusing things about Medicare for people jumping into it for the first time is the seemingly Alphabet soup nature to it all — what are all these different pieces with letter names?

So our goal here is to break it down for you, and you’ll hopefully soon see how it all fits together. And by the way, if something doesn’t seem to click or add up for you, please reach out to us — we’re here to help!

So here we go. There are four parts to Medicare. They are:

  • Medicare Part A, which is the hospital insurance portion of Original Medicare.
  • Medicare Part B, which is the medical insurance portion of Original Medicare covering things like doctors’ visits, outpatient care, ambulance services, and more.
  • Medicare Advantage (Part C), which is an alternative to Original Medicare (Parts A & B) that is offered by private insurers. It must cover everything that Original Medicare covers.
  • And Medicare Prescription Drug Plans (Part D). These plans are available to anyone who is eligible for Medicare.

Additionally, Medicare eligible individuals can elect to receive additional Medicare coverage from private insurers known as Medicare Supplement, or Medigap, plans. Medigap can cover the additional 20% of healthcare costs that Original Medicare does not pick up.

Medicare Part A is Hospital Insurance and it:

  • Helps cover inpatient care in hospitals (room cost, hospital meals and supplies), including critical access hospitals, and skilled nursing facilities. It does not cover custodial or long-term care.
  • Helps cover hospice care and some home health care. You must meet certain conditions to get these benefits.
  • There is a $1,340 deductible for Part A, but once met, days 1-60 of hospitalization are covered 100%. After 60 days, if you require more hospitalization, you must pay an amount set by Medicare.
  • Most people do not have to pay a monthly premium for Medicare Part A. More on that here.

Medicare Part B is Medical Insurance and it:

  • Helps cover doctors’ services, hospital outpatient care, and home health care.
  • Helps cover tests, shots and some preventive services to maintain your health and to keep certain illnesses from getting worse (flu shots, PAP tests).
  • There is a monthly premium ranging from $134 to $428.60, depending on your income, and a $183 annual deductible. Once the deductible is met, Part B generally pays 80% of the Medicare-approved amount for covered services, which means you pay 20% of those services.
  • Part A and Part B together are commonly referred to as “Original Medicare.” Original Medicare is offered by the government, and again, in most cases, you’ll automatically get Part A and Part B starting the first day of the month you turn 65 if you are already getting Social Security benefits.

Medicare Part C is Medicare Advantage

Instead of getting Medicare Part A and Part B, you can enroll in/purchase a Medicare Advantage Plan (also called “Part C”).

Medicare Advantage Plans are health plans run by Medicare-approved private insurance companies, and have different rules and costs, but offer at least the same benefits of Medicare Part A and Part B, and in some cases also include prescription drug coverage, vision, and dental—but the health coverage is generally limited to in-network doctors and hospitals.

Please bear in mind, however, that even if you do opt to go the Medicare Advantage route you are still required to pay the Medicare Part B monthly premiums.

Why would someone opt to buy a Medicare Advantage Plan over getting Medicare Part A & Part B?

When it comes to Medicare the decision is yours, however, you may want to get a Medicare Advantage Plan instead of Original Medicare if:

  • You take prescription drugs. With a few exceptions, most prescriptions aren’t covered in Original Medicare. Many Medicare Advantage Plans include prescription drug coverage.
  • Your area has a large selection of in-network doctors and hospitals.
  • You don’t travel and your doctor is in-network for the Medicare Advantage Plan you want.
  • You’re healthy and don’t expect to need hospitalization services or medical attention beyond preventive health care.
  • You want to cap your out-of-pocket health spending. Original Medicare has no out-of-pocket maximum. Medicare Advantage plans, by law, have an out-of-pocket maximum of $6,700 per year, as long as you use in-network doctors.
  • You want an alternative to the 20% coinsurance charged by Original Medicare Part B – remember, the 20% is unlimited (unless you have a Medicare Supplement Plan), whereas Medicare Advantage out-of-pocket is limited to $6,700 for in-network services.
  • You want coverage for vision and dental. Original Medicare doesn’t cover these outline services. Certain Medicare Advantage Plans do.

Medicare Part D is Prescription Drug Coverage

There are two ways to get prescription drug coverage through Medicare – either as an add-on known as Medicare Part D to your Original Medicare Plan (Part A and Part B), or as part of your Medicare Advantage Plan (Part C).

There are several different Part D plans, and they vary in cost and medications covered. Also note that Medicare Part D is provided by private insurance companies that have contracts with the government, unlike Medicare Part A and Part B, which are provided directly by the government.

Each Medicare Prescription Drug Plan has its own list of covered drugs, called a formulary. Many Medicare drug plans classify drugs by tiers and each tier has a different cost associated with it. Before you choose a Prescription Drug Plan, it’s best to look at the plan’s list of drugs to see if your medication(s) is covered, and how much it will cost.

What is Medicare Supplement Insurance (also known as Medigap)?

A Medicare Supplement Insurance (Medigap) policy is sold by private companies and can help pay the remaining 20% of costs Original Medicare doesn’t cover. Medicare Supplement Insurance can help cover:

  • Medical service copayments
  • Plan deductibles
  • Skilled nursing care
  • Excess hospitalization charges
  • Medical emergencies when you travel outside the U.S.
  • Medicare Supplement policies fill in the gap between what Original Medicare covers and what it doesn’t. If you have Original Medicare and you buy a Medigap policy, Medicare will first pay its share of the Medicare-approved amount for covered health care costs. Then your Medigap policy pays its share.

How are Medicare Supplement plans and Medicare Advantage plans different?

A Medigap/Medicare Supplement policy is different from a Medicare Advantage Plan.

A Medicare Supplement Plan is insurance coverage in addition to your Original Medicare coverage. It helps cover the 20% of hospitalization and doctor expenses that Parts A and B don’t cover, and you can visit ANY doctor who accepts Medicare.

The most you will pay in a given year is the sum of your Medicare Supplement and Medicare Part B premiums.

A Medicare Advantage Plan is a way to get Medicare benefits instead of getting Original Medicare. Medicare Advantage Plans cover in-network doctor visits, hospitalization, and often prescription drug costs. Your out-of-pocket maximum is $6,700 per year, as long as you use in-network doctors and hospitals.
