ANSWER FIRST: To find out, note your plan letter and current monthly premium, then compare what other companies charge for the identical plan letter at your age and ZIP code. Medigap benefits are standardized, so a lower price buys exactly the same coverage.

Paying Too Much for Your Medicare Supplement? Here's How to Find Out

Quick Answer

Yes, you may be paying too much for your Medicare Supplement plan. Because all Medigap plans with the same letter (like Plan G or Plan N) offer identical benefits regardless of which insurance company sells them, the only real difference is the price. Many beneficiaries are paying $50-$150 more per month than necessary — simply because they've never compared rates.

The Problem Most Medicare Beneficiaries Don't Know They Have

Here's something that surprises a lot of people: the Medicare Supplement plan you're paying $210 a month for might be available from a different insurer for $140 a month — with exactly the same coverage. Same benefits. Same protections. Same network. Just a different name on the card and a much lower bill.

This isn't a rare situation. It's actually the norm. Millions of Americans on Medicare are quietly overpaying for their Medigap coverage, not because they made a bad decision when they enrolled, but because premiums drift higher over time while better-priced options sit just out of view. Insurance companies count on the fact that most people, once enrolled, stay put.

If you signed up for your Medicare Supplement plan when you first turned 65 and haven't looked at it since, there's a very real chance you could be spending hundreds — or even over a thousand dollars — more per year than you need to. This guide will help you find out.

Why Medicare Supplement Premiums Vary So Widely

To understand why overpaying is so common, you first need to understand how Medicare Supplement pricing actually works.

The federal government standardizes Medigap benefits. That means a Plan G sold by Aetna covers exactly the same things as a Plan G sold by Mutual of Omaha, Blue Cross Blue Shield, or any other insurer. Congress designed it that way on purpose — so consumers could compare plans easily without worrying that one company's plan secretly had better benefits than another's.

But here's the catch: while the benefits are standardized, the premiums are not. Each insurance company sets its own rates, and those rates can vary dramatically from one insurer to the next — even in the same zip code, for the same plan, for the same age.

In 2026, the average monthly premium for Plan G (the most popular Medigap plan) is approximately $165 per month for a 65-year-old. But that's just an average. Depending on your state and the insurer, you might find Plan G priced anywhere from under $100 to well over $300 per month. Plan N, another strong option, averages around $123 per month at age 65 — but carries the same wide range depending on who's selling it.

That spread isn't small. A $100-per-month difference between the lowest and highest priced Plan G in your area adds up to $1,200 every single year — for coverage that is, by law, identical.

What You're Actually Paying For (And What You're Not)

When you buy a Medigap plan, you are paying for a standardized set of benefits defined by Medicare. The plan letter tells you everything you need to know about what's covered.

Plan G, for example, covers:

Medicare Part A coinsurance and hospital costs
Medicare Part B coinsurance or copayments
Part A hospice care coinsurance
Skilled nursing facility coinsurance
Part A and Part B excess charges
Foreign travel emergency care (up to plan limits)

The only cost Plan G does not cover is the Part B deductible ($257 in 2026), which you pay once per year.

Plan N covers most of the same benefits as Plan G, with slightly more cost-sharing — modest copays of up to $20 for office visits and up to $50 for emergency room visits, and it doesn't cover Part B excess charges. In exchange, you typically pay a lower monthly premium.

Here's what matters most: when you're comparing Plan G from Company A to Plan G from Company B, you are not comparing benefits. They are identical. The only things that actually differ are the monthly premium and the quality of customer service. That's it. You're not giving anything up by choosing a lower-priced insurer for the same letter plan.

Many people assume a higher price means better coverage. With Medigap, that assumption is simply incorrect.

The Three Signs You're Probably Overpaying

Not sure if this applies to you? Here are three clear indicators that it's time to take a closer look at what you're paying.

1. You Enrolled at 65 and Haven't Shopped Since

When you first became eligible for Medicare, you likely enrolled in a Medigap plan during your open enrollment window — which is smart. But many people choose a plan and then never revisit it. Premiums that seemed reasonable five or ten years ago may now be significantly higher than what's available elsewhere. The market changes. New insurers enter. Competitive pricing shifts. If you haven't compared rates since you first signed up, you're almost certainly not getting the best price anymore.

2. Your Premiums Have Increased Noticeably Year Over Year

Medicare Supplement premiums don't stay flat. Insurers file for rate increases regularly, and in 2026, those increases varied widely — from as low as 5.3% (Anthem in Wisconsin) to as high as 22.6% (Wellmark in South Dakota), depending on the company and state. If your premium has climbed by double digits in recent years and you've simply accepted it as normal, you may be funding someone else's risk pool with no benefit to yourself.

3. You've Never Compared Quotes From More Than One Company

This is the most common reason people overpay. If you enrolled through one agent, one insurer, or one source without comparing multiple quotes, you have no way of knowing whether you're getting a fair price. Research consistently shows that seniors who shop and switch insurers can save $50-$100 per month — that's $600 to $1,200 back in your pocket every year, for the same exact coverage.

If any of these signs sound familiar, you're in the right place. In Part 2, we'll walk you through exactly how to check whether you're overpaying — and what to do about it if you are.

How to Find Out If You're Overpaying in 5 Minutes

This part is simpler than most people expect. You don't need an insurance agent, a spreadsheet, or a phone call. Here's exactly what to do:

Step 1: Pull out your current premium bill. Find your most recent Medicare Supplement statement and write down two things: your plan letter (Plan G, Plan N, Plan F, etc.) and your monthly premium amount. That's your starting point.

Step 2: Visit medicaresavingschecks.com. This free tool lets you run a side-by-side comparison of what other insurance companies charge for the exact same plan letter in your ZIP code. The coverage is identical — the only difference is the price. Enter your information and see what comes up.

Step 3: Note the lowest available rate for your plan letter. You're looking for the lowest monthly premium shown for your specific plan type in your area. Write that number down next to what you currently pay.

Step 4: Calculate your potential annual savings. Subtract the lower rate from what you're currently paying. Then multiply that number by 12. That's how much you could save in a single year. If the difference is $50 a month, that's $600 a year. If it's $100 a month, that's $1,200 back in your pocket.

Step 5: Decide if switching makes sense. If the savings are meaningful to you, the next step is simply finding out if you're eligible to switch. That part is covered below — and it's easier than you might think.

The whole process takes about five minutes. Many people are surprised — and a little frustrated — by what they find.

Can You Actually Switch? What You Need to Know

Here's where people sometimes hesitate, and understandably so. Outside of your initial Medicare Supplement open enrollment period (which runs for six months starting when you turn 65 and enroll in Medicare Part B), switching plans usually requires answering health questions. This is called medical underwriting, and it means the insurance company can consider your health history before approving you.

That said, many people still qualify — especially those in relatively good health. It's not an automatic barrier.

There are also important exceptions where you may have guaranteed issue rights, meaning you can switch without health questions:

Your current Medicare Supplement plan is being discontinued
You've moved out of your plan's service area
Your insurance company went bankrupt or lost its license

Even if none of those apply to you, it's still worth checking. Getting a quote costs nothing, and there's no obligation to do anything. You won't know what's available to you until you look — and the worst outcome is simply staying where you are.

What About Medicare Advantage? Is That a Better Deal?

It's a fair question, and worth addressing directly.

Medicare Advantage plans often advertise $0 premiums, which sounds appealing. But they work differently from Medicare Supplement. With Medicare Advantage, you're typically locked into a network of doctors and hospitals, you may need prior authorization for certain procedures, and you'll often pay copays and deductibles each time you use care. Your out-of-pocket costs can add up quickly if you have a serious illness or need frequent medical attention.

Medicare Supplement works alongside original Medicare. You can see any doctor or specialist in the country who accepts Medicare — no referrals, no network restrictions. Your costs are more predictable because the plan picks up what Medicare doesn't.

For people who value that freedom and want to know what their healthcare will cost before they need it, Medicare Supplement is often the better fit. But only if you're not overpaying for it. Paying $80 more per month than you need to for the same coverage defeats the purpose.
