If you are new to Medicare, the alphabet of “parts” and the stack of mail can feel overwhelming. Take a breath, it is more manageable than it looks. In this guide we will walk through what each part of Medicare actually does, how the pieces fit together, and how to think about choosing. No jargon, no pressure, just clear answers so you can feel confident about your decisions.

By the end, you will understand the four parts of Medicare, the two main paths most people choose, and the questions worth asking before you pick a plan.

What is Medicare?

Medicare is the federal health insurance program primarily for people 65 and older, and for some younger people with certain conditions. Rather than one single plan, it is built from a few parts that each cover different things. Once you see how they fit, the whole picture gets a lot clearer.

People often use the term Original Medicare to mean Parts A and B together. From there, you decide how to round out your coverage, and that is where the choices come in.

Part A — Hospital insurance

Part A helps cover inpatient hospital stays, skilled nursing facility care, hospice, and some home health care. Most people do not pay a monthly premium for Part A, because they (or a spouse) paid into Medicare through years of working.

Think of Part A as the “hospital” side of your coverage, it is there for the bigger, inpatient events.

Part B — Medical insurance

Part B helps cover doctor visits, outpatient care, preventive services, lab tests, and medical equipment. Part B has a monthly premium.

Together, Parts A and B (Original Medicare) cover a lot, but not everything. They generally do not cover routine dental, vision, or prescription drugs, and they leave some out-of-pocket costs. That is why most people add to Original Medicare in one of two ways, which we will cover next.

Part C — Medicare Advantage

Medicare Advantage (Part C) is an alternative to Original Medicare offered by private insurers approved by Medicare. These plans bundle your coverage into one plan, and many include prescription drug coverage and extra benefits, which vary by plan and from year to year.

With Medicare Advantage, you typically use a plan’s network of providers, and the plan sets its own copays and out-of-pocket maximum. It can be a good fit if you like having your coverage in one place and you are comfortable with a network.

Part D — Prescription drug coverage

Part D is prescription drug coverage, offered through private insurers approved by Medicare. You can get it as a standalone plan (often paired with Original Medicare or a Medigap plan), or it may be built into a Medicare Advantage plan.

Here is the key thing: every Part D plan has its own formulary (its list of covered drugs) and its own pricing. So the “best” Part D plan really depends on the specific medications you take.

The piece that fills the gaps — Medicare Supplement (Medigap)

There is one more important piece. Medicare Supplement plans, also called Medigap, work alongside Original Medicare to help pay some of the out-of-pocket costs (like copayments, coinsurance, and deductibles) that Parts A and B leave behind.

Medigap plans are standardized, which means a given plan letter offers the same core benefits no matter which company sells it. What changes is the price and the company. (Medigap does not include drug coverage, so you would typically pair it with a separate Part D plan.)

The two paths most people choose

When you put it all together, most people pick one of two approaches:

Path 1 — Original Medicare + Medigap + Part D

You keep Original Medicare, add a Medigap plan to help with out-of-pocket costs, and add a standalone Part D plan for prescriptions. You can generally see any provider who accepts Medicare, with no network restrictions.

Path 2 — Medicare Advantage (Part C)

You get your coverage bundled into one plan from a private insurer, often including drug coverage and extra benefits, using the plan’s network.

Neither path is “best” for everyone. The right choice depends on your doctors, your medications, your budget, and how you like to get your care. This is exactly the kind of decision a licensed advisor can help you think through.

What Medicare usually does not cover

A few things commonly surprise people. Original Medicare generally does not cover:

• Routine dental — cleanings, fillings, dentures
• Routine vision — eye exams for glasses, and the glasses themselves
• Long-term custodial care — extended help with daily activities

There are separate plans to help with each of these, so it is worth knowing your options.

When can you enroll?

Timing matters with Medicare. A few windows to know:

• Turning 65: you have an Initial Enrollment Period around your 65th birthday.
• Annual Enrollment Period (AEP): October 15 – December 7, when you can change Medicare Advantage or Part D coverage.
• Medicare Advantage Open Enrollment: January 1 – March 31.
• Special Enrollment Periods: certain life events (like moving or losing other coverage) can open a window outside the usual dates.

It is a good idea to review your coverage each year, since plans can change. A licensed advisor can explain the timing that applies to your situation.

Questions worth asking before you choose

1. Are my doctors covered?
2. Are my medications covered, and what will they cost?
3. What are the total costs — premium, copays, deductibles, and the out-of-pocket maximum?
4. Does the plan cover where I live and travel?
5. What extra benefits matter to me, if any?
6. What happens if my needs change next year?
