How to Choose Your First Medicare Supplement Plan in 2027

How to Choose Your First Medicare Supplement Plan in 2027. Step-by-step Guidance for Selecting the Right Plan

When I first started looking at Medicare, I felt lost. There were letters everywhere. Plan G. Plan N. Part A. Part B. It felt like alphabet soup, and nobody would give me a straight answer.

If you are turning 65 soon, or you are leaving a job that gave you health insurance, you may feel the same way. That is okay. I wrote this guide to make choosing your first Medicare Supplement plan in 2027 as simple as I can.

I will walk you through what these plans are, when to buy one, which plans most people pick, and how to compare prices. I will also share the mistakes I see people make most often. By the end, you should feel ready to pick a plan with confidence.

One quick note: I am not a licensed insurance agent or a financial advisor. This article is for learning. For advice about your own situation, talk with a licensed agent or your free local SHIP counselor (more on that later).

What Is a Medicare Supplement Plan?

Let me start with the basics. Original Medicare has two main parts:

• Part A helps pay for hospital stays.
• Part B helps pay for doctor visits, tests, and outpatient care.

Original Medicare is good coverage, but it does not pay for everything. You still have to pay deductibles, copays, and coinsurance. For most Part B services, Medicare pays 80%, and you pay the other 20%. And here is the scary part: Original Medicare has no yearly cap on what you pay. If you get really sick, that 20% can add up to thousands of dollars.

That is where a Medicare Supplement plan comes in. People also call it Medigap because it fills the “gaps” in Original Medicare. You buy it from a private insurance company. In return, it pays some or all of those leftover costs.

What a Medigap plan does NOT cover

I want to be clear about this, because it trips up a lot of people. Medigap plans usually do not cover:

1. Prescription drugs. You need a separate Part D drug plan for that.
2. Routine dental care.
3. Routine vision care or glasses.
4. Hearing aids.
5. Long-term care, like a nursing home stay for daily living help.

So when you pick a Medigap plan, plan to pick a Part D drug plan too.

Why I like Medigap plans

Here is what makes Medigap plans so popular:

• You can see any doctor who takes Medicare. There are no networks. That is true anywhere in the U.S.
• No referrals. You do not need permission to see a specialist.
• Predictable costs. With the right plan, you know about how much you will pay each year.
• Plans are standard. A Plan G from one company covers the same things as a Plan G from another company. (Massachusetts, Minnesota, and Wisconsin use their own standard plans.)

When Should You Buy Your First Medigap Plan?

If I could tell you only one thing in this whole article, it would be this: timing matters more than almost anything else.

Your Medigap Open Enrollment Period

You get a special one-time window called your Medigap Open Enrollment Period. It lasts 6 months. It starts on the first day of the month that you are both:

• 65 or older, and
• Signed up for Medicare Part B.

Here is an example. Say you turn 65 in March 2027, and your Part B starts March 1. Your window runs from March 1 through August 31, 2027.

Why this window is so important

During these 6 months, the law protects you. An insurance company:

1. Cannot turn you down because of your health.
2. Cannot charge you more because of health problems you already have.
3. Must sell you any Medigap plan it offers in your state.

After the window closes, things change. In most states, companies can ask you health questions. They can charge you more, or even say no. This is called medical underwriting. A few states have extra rules that make it easier to switch later, but most do not. So I always tell people: do not miss this window.

Wait, isn’t Open Enrollment in the fall?

Good question, and it confuses a lot of people. The fall Medicare Open Enrollment (October 15 to December 7) is for Medicare Advantage and Part D drug plans. It is not a free pass to switch Medigap plans. Your Medigap window is tied to your own 65th birthday and Part B start date.

What if I’m still working past 65?

If you have health insurance through your job (or your spouse’s job) and you wait to sign up for Part B, your Medigap window waits too. It starts when your Part B starts. Just make sure your job coverage counts so you don’t face a Part B late penalty. Check with your employer’s benefits office before you delay.

The Medigap Plan Letters, Made Simple

There are 10 standard Medigap plans. Each has a letter: A, B, C, D, F, G, K, L, M, and N. Don’t let that scare you. For most people new to Medicare in 2027, the choice comes down to just three options.

First, one important rule. Plans C and F are closed to anyone who became eligible for Medicare on or after January 1, 2020. Those plans paid the Part B deductible, which is no longer allowed for new enrollees. So if you are turning 65 in 2027, you cannot buy Plan C or Plan F.

The big three for 2027

Plan G: my top pick for most people

Plan G is the most popular plan for new Medicare members, and I understand why. After you pay the yearly Part B deductible, Plan G pays your share of everything else Medicare covers. That includes the 20% coinsurance, hospital costs, and something called Part B excess charges. (Those are extra fees some doctors can charge above what Medicare allows.)

The 2026 Part B deductible is $283. Medicare’s trustees project it will be about $292 in 2027, but the final number usually comes out in November. Either way, it is a small, known cost.

Plan N: the money-saver

Plan N covers a lot, just like Plan G, but it usually costs less each month. In exchange, you pay:

• Up to $20 for some doctor visits.
• Up to $50 for an emergency room visit that does not lead to a hospital stay.
• Any Part B excess charges (Plan N does not cover these).

If you are fairly healthy and your doctors accept Medicare’s full payment, Plan N can save you real money.

High-Deductible Plan G: lowest premium, more risk

This plan has the same benefits as regular Plan G, but the deductible is higher. For 2027, you pay the first $3,050 of Medicare-covered costs yourself (CMS announcement). After that, the plan pays 100% for the rest of the year. Premiums are often much lower. I only suggest it if you can easily pay that $3,050 in a bad year.

What about the other letters?

Plans A, B, D, K, L, and M still exist, but fewer people choose them. Plans K and L are interesting because they have a yearly cap on what you pay. They cover only part of your costs until you reach that cap. They can work for some budgets, but they are harder to plan around.

How I Would Choose My First Medigap Plan: 7 Simple Steps

Here is the step-by-step process I recommend. Grab a notebook and work through it one step at a time.

1. Find your start date. Write down the month you turn 65 and the date your Part B begins. Then count 6 months forward. That is your Medigap Open Enrollment window. Put it on your calendar.
2. Review your health and habits. How often do you go to the doctor? Do you have ongoing health problems? Do you see specialists? If you go a lot, Plan G’s steady costs may be worth it. If you rarely go, Plan N or High-Deductible Plan G may save you money.
3. Think about your budget. Ask yourself two questions. How much can I pay each month? And how much could I pay in one bad year? Plan G costs more monthly but offers more protection. High-Deductible Plan G costs less monthly but could cost you $3,050 in a tough year.
4. Check your doctors. Ask your doctors if they accept Medicare “assignment.” That means they take Medicare’s approved amount as full payment. If they do, excess charges will not affect you, and Plan N becomes more attractive.
5. Pick your letter first, then shop. Since every Plan G covers the same things, decide on your plan letter before you compare companies. This keeps shopping simple.
6. Compare prices from several companies. Prices for the same plan can vary widely. Two companies in the same zip code can charge very different amounts for the same coverage. Get at least three quotes.
7. Don’t forget Part D. Pick a Part D drug plan at the same time. If you go without drug coverage and do not have other good coverage, you may pay a late penalty for as long as you have Part D.

How Medigap Prices Work (and How to Compare Them)

The price you see today is not the whole story. How a company sets its prices can make a big difference over time.

The 3 ways companies price Medigap plans

1. Community-rated. Everyone pays the same price, no matter their age. Your price can still go up because of inflation, but not just because you get older.
2. Issue-age-rated. Your price is based on your age when you buy the plan—buying younger locks in a lower base price. It can still rise with inflation.
3. Attained-age-rated. Your price is based on your current age, so it goes up as you get older. These plans often look cheapest at 65, but they can become the most expensive later.

When you get a quote, always ask, “How is this plan priced?”

What to ask every insurance company

Here is the checklist I would use:

• What is the monthly premium for my age and zip code?
• Which pricing method do you use?
• How much have your rates gone up in the last few years?
• Do you offer discounts? Many companies give a household discount if you and your spouse both enroll. Some also give a discount for paying yearly or by bank draft.
• How strong is the company? Look for good financial ratings and a long history.

Where to compare

• Medicare.gov’s Medigap tool lets you see plans and companies in your area.
• Your state’s insurance department often posts rate guides.
• A licensed independent agent can quote many companies at once. The insurer usually pays them, so it does not cost you extra. Just make sure they show you more than one company.
• Your local SHIP (State Health Insurance Assistance Program) gives free, unbiased help. You can find yours at shiphelp.org.

Medigap vs. Medicare Advantage: Which Road Should You Take?

Before you pick a Medigap plan, you need to make a wider choice. You can get your Medicare benefits in one of two ways:

• Road 1: Original Medicare + a Medigap plan + a Part D drug plan.
• Road 2: A Medicare Advantage plan (also called Part C), which bundles everything into one private plan.

You cannot use a Medigap plan with Medicare Advantage. It is one road or the other.

My honest take

Medicare Advantage can be a good fit if you are healthy, want a low monthly cost, and like the extras. Medigap is often the better fit if you want freedom to see any doctor, travel a lot, or have health problems that need regular care.

Here is the part many people miss. If you start with Medicare Advantage and later want to switch to Medigap, you may have to pass health questions. You could be turned down. That is why your first choice at 65 matters so much. (There is a limited “trial right” if you try Medicare Advantage first and leave within 12 months, so ask a SHIP counselor if this applies to you.)

8 Mistakes I Want You to Avoid

These are some of the most common mistakes people make. Each one is easy to avoid once you know about it.

1. Missing your 6-month window. This is the big one. After it closes, you may never get the same chance to buy any plan without health questions.
2. Picking only by price. The cheapest plan today may not stay cheap. Ask how the company sets and raises its prices.
3. Thinking a brand name means better coverage. A Plan G is a Plan G. A big-name company does not give you extra benefits for the same letter.
4. Forgetting about Part D. Medigap does not cover most prescriptions. Skipping Part D can lead to a lifelong penalty.
5. Buying more than you need, or less. Match your plan to your health and budget, not to what your neighbor bought.
6. Ignoring excess charges. If you pick Plan N, check that your doctors accept Medicare assignment.
7. Assuming you can switch easily later. In most states, changing plans later means passing health questions. Choose the first time carefully.
8. Not asking for free help. Your SHIP counselor is free and does not sell insurance. Use them.

Frequently Asked Questions About Medigap in 2027

Q: Can I buy Plan F in 2027?

A: Only if you were eligible for Medicare before January 1, 2020. If you are turning 65 in 2027, Plan F and Plan C are not available to you. Plan G is the closest option.

Q: How much does a Medigap plan cost?

A: It depends on your age, zip code, gender, tobacco use, the plan letter, and the company. Prices also vary by state. The best way to know is to get several quotes for your exact zip code.

Q: Do I still pay the Part B premium if I have Medigap?

A: Yes. You pay your Part B premium to Medicare and your Medigap premium to the insurance company. The 2026 Part B premium is $202.90 a month. Medicare’s trustees project about $209.50 for 2027. The official 2027 amount is usually announced in November.

Q: Does Medigap cover me when I travel?

A: Inside the U.S., yes. You can see any provider who takes Medicare. Plans C, D, F, G, M, and N also cover some emergency care in other countries, up to plan limits.

Q: Can I have Medigap and Medicare Advantage at the same time?

A: No. A Medigap plan only works with Original Medicare.

Q: Does Medigap cover my spouse?

A: No. Each plan covers one person. You and your spouse each need your own plan. Many companies offer a discount if you both join.

Q: Can I change my Medigap plan later?

A: You can apply anytime. But outside your Open Enrollment window, most states allow the company to ask health questions and say no. Some states have special rules, like a yearly “birthday” window. Check your state’s rules.

Q: Will my Medigap plan ever be canceled?

A: Medigap plans are “guaranteed renewable.” As long as you pay your premium on time, the company cannot drop you, even if your health changes.

Q: Who can give me free, honest help?

A: Your local SHIP counselor. SHIP is a free government program, and its counselors do not sell insurance.

My Final Thoughts on Choosing Your First Medigap Plan

Choosing your first Medicare Supplement plan in 2027 does not have to be hard. When I break it down, it really comes down to a few simple moves:

• Mark your 6-month Medigap Open Enrollment window and buy during it.
• Decide between Medigap and Medicare Advantage before you shop.
• Pick your plan letter. For most new members, that means Plan G, Plan N, or High-Deductible Plan G.
• Compare at least three companies and ask how each one sets its prices.
• Add a Part D drug plan so your prescriptions are covered.

Take your time, ask questions, and use the free help available. A little planning now can save you money and stress for years to come.

Keep an eye on Medicare.gov in November 2026. That is when the official 2027 Part B premium and deductible are usually announced. Then you will have every number you need to make your choice.

Why choose Steve Turner Insurance Specialist?

Because I’m an “Insurance Specialist.” An “insurance specialist” is a broad term that includes insurance agents and insurance brokers, but the key difference is who the agent represents versus who the broker represents.

An “insurance agent” works directly for an insurance company and sells its specific policies to clients.

An “insurance broker” acts as an independent intermediary, comparing policies from multiple companies to find the best fit for their client’s needs, essentially representing the client rather than the insurance company.

I am both a licensed Insurance Agent and a licensed Insurance Broker.

My number one goal in life is to help people and ensure, without a shadow of a doubt, that you and your family are secure and protected. I will always be by your side, helping you mitigate risk by providing the industry’s best and most affordable insurance solutions.

I will find insurance plans for the entire family to help cover whatever life throws at you. I can help you save on severe medical emergencies, find a health insurance plan with low- or no-cost doctor visits and affordable prescription medications, and protect your family in the event of an unexpected accident or illness.

Best of all, it doesn’t cost you anything extra to use an experienced Insurance Agent and Broker like me to help you find the Insurance Plans that fit your individual, family, or business needs.

The companies that sell the insurance plans “you choose“ pay me – you don’t pay me. Calling any big insurance company directly won’t get you a lower price, as they will forward your call to the next available insurance agent on their list. You won’t have had any opportunity to learn about the insurance agent you’re speaking with in advance, understand their qualifications or experience level, or make an informed choice about who you want to work with.
