👉 Medicare 101: A Simple Explanation for Beginners

When I first sit down with someone new to Medicare, most people tell me the same thing:

“Everything I’ve read sounds like Chinese.”

That’s completely normal.

This is why I like to start with what I call a Medicare 101. Sometimes I even recommend doing this well before turning 65. It helps to hear it once, go home and think about it, and then come back with questions. It takes the pressure off and keeps it from feeling like a rushed decision.

How Medicare Starts

When you were working and receiving a paycheck, you probably noticed money coming out for:

• Social Security

• Medicare

That Medicare tax you’ve been paying goes toward your Medicare Part A.

Medicare Part A (Hospital Coverage)

Part A covers:

• Hospital stays

• Hospice

• Limited blood coverage

Most people qualify for Part A at no additional monthly cost when they turn 65 because they’ve already paid into it during their working years.

Medicare Part B (Medical Coverage)

Part B covers:

• Doctor visits

• Imaging (like MRIs, X-rays)

• Durable medical equipment

Unlike Part A, Part B does have a monthly premium.

• If you are drawing Social Security, it will come out of your check

• If you delay Social Security, you’ll be billed quarterly

Your Medicare Options

Once you’re on Medicare, there are a few different directions you can go.

Option 1: Original Medicare Only

This would be:

• Part A

• Part B

• (usually a standalone drug plan)

I rarely see people choose this option.

The reason is because it leaves you exposed to:

• deductibles

• coinsurance

• ongoing costs

But the biggest issue is:

👉 There is no maximum out-of-pocket

Think of a max out-of-pocket like a stoplight. It’s the most you would spend in a year.

With Original Medicare, that stoplight doesn’t exist.

For example:

• You could be responsible for 20% of treatments like chemotherapy

• And there is no cap on what you could spend

That can get very expensive very quickly.

Option 2: Medicare Supplement (Medigap)

A Medicare Supplement helps cover what Medicare doesn’t pay.

These plans:

• have a monthly premium

• come in standardized plan letters (like Plan G)

Important to know:

👉 A Plan G is the same no matter which company you choose

The only real difference is the price (premium).

How a Supplement Works

Using Plan G as an example:

• You pay the Part B deductible (around a few hundred dollars per year)

• After that, the plan covers most remaining costs

That includes things like:

• hospital coinsurance

• excess charges

After the deductible, your out-of-pocket costs are very minimal.

One important note

If you choose a supplement, you will also need a separate drug plan (Part D).

If you go without drug coverage and try to add it later, you may face a penalty.

Option 3: Medicare Advantage (Part C)

Medicare Advantage plans bundle everything together.

These plans include:

• Part A

• Part B

• Part D (drug coverage)

And often include extras like:

• dental

• vision

• hearing

• gym memberships

Why are they low cost?

Many people ask how these plans can be so affordable.

The easiest way to think about it is:

👉 Medicare is like a big bucket of money

👉 You paid into it while you were working, we all pay into it while we’re working, and you continue contributing through your Part B premium

So everyone is contributing to this bucket.

👉 When you choose a Medicare Advantage plan, Medicare takes a handful of money out of that bucket and gives it to the Advantage plan to replace your Medicare for that year

How they work

Most Advantage plans have:

• low or $0 monthly premium

• copays for services

• a maximum out-of-pocket (very important)

They also come in two main types:

• HMO → must stay in network

• PPO → can go out of network (higher cost)

What to look for

When choosing a Medicare Advantage plan, I focus on:

• a low max out-of-pocket

• making sure your doctors are in network

• making sure your prescriptions are covered

These plans often feel similar to employer coverage:

• copays for doctor visits

• structured costs

• predictable spending

Final Thoughts

This is just a bird’s-eye view of Medicare.

The most important thing to understand is:

👉 There is no one-size-fits-all plan

👉 The “best” option depends on your situation

That’s why I always recommend sitting down and walking through it together, so you can make a decision that feels clear and confident.
