If you’re reading this, you probably already have a Medicare Supplement policy—or you’re considering purchasing one and want to better understand how it works. Medicare Supplement insurance, also known as Medigap, helps pay many of the deductibles, copayments, and coinsurance costs that Original Medicare (Parts A and B) doesn’t cover. By reducing your out-of-pocket medical expenses, a Medicare Supplement plan can make healthcare costs much more predictable and provide valuable peace of mind throughout retirement.

If you’re new to Medicare Supplement insurance, we recommend first reading our complete Medicare Supplement Guide, where we explain how Medigap plans work, the different plan options, and why they’re so popular among retirees.

If you already have coverage, you may be wondering whether a Medicare Supplement replacement (change) could help lower your monthly premium without sacrificing the quality of your benefits. The good news is that because Medicare Supplement plans are standardized by the federal government, you may be able to replace your current policy with the exact same coverage from another insurance company—often at a significantly lower monthly cost.

In this guide, we’ll explain how Medicare Supplement replacement works, when it makes sense to change plans, and the steps you can take to potentially save money while keeping the dependable coverage you rely on. Let’s begin with a few important facts every Medicare Supplement policyholder should know.

Benefits Of Switching Your Medicare Supplement

You could save hundreds, even thousands of dollars per year, without losing any coverage or quality

Service from your new Medicare agency could be better with regular policy reviews

Potentially gain extra benefits such as gym, vision, and hearing discount programs, at no cost

Did You Know?

You can replace your Medicare Supplement policy anytime, 12 months out of the year. There is no designated enrollment period to change a policy.

Important Facts About Medicare Supplement Replacement

1. Medicare Supplement Plans Are Standardized

One of the biggest advantages of Medicare Supplement replacement is that Medicare Supplement plans are standardized and regulated by the federal government. This means the benefits of each plan are identical regardless of which insurance company sells it. When you replace your Medicare Supplement, you can expect the same medical coverage and a very similar experience—you may simply pay a lower monthly premium.

For example, all Medicare Supplement plans allow you to see any doctor or hospital in the U.S that accepts Medicare. If you replace your current Medicare Supplement policy with another insurance company, you’ll continue to have the same nationwide provider access without worrying about networks or referrals.

2. Your Plan Letter Determines Your Coverage

Each Medicare Supplement plan is identified by a letter, such as Plan G, Plan N, or Plan F. The plan letter determines your benefits and how much you’ll pay out of pocket for deductibles, copayments, and coinsurance.

Because Medicare standardizes these plans, Plan G from Aetna provides the exact same medical benefits as Plan G from Mutual of Omaha, Cigna, UnitedHealthcare, or any other insurer. The main difference is in the monthly premium the insurer charges you for the coverage. Other differences can include customer service, financial strength, and the company’s history of rate increases. Although, many of the top companies are similar in these areas.

3. Medicare Approves Claims the Same Way

Another reason Medicare Supplement replacement is usually seamless is that Medicare remains your primary insurance. Your Medicare Supplement policy is secondary coverage and pays its share after Medicare processes the claim.

If Medicare approves a covered claim, your Medicare Supplement carrier must also process the claim according to the standardized benefits of your plan. This consistency makes replacing your policy much more straightforward than changing many other types of health insurance.

4. The Same Coverage Can Cost Very Different Amounts

Although the coverage remains the same, Medicare Supplement premiums can vary significantly between insurance companies. Premiums are based on each insurer’s pricing, claims experience, administrative costs, and overall business strategy.

As a result, one company may charge hundreds of dollars more per year than another for the exact same Medicare Supplement coverage. In many cases, a Medicare Supplement replacement can produce substantial long-term savings while allowing you to keep the same doctors and identical benefits.

It’s also important to know that your premium is not based on your personal medical history or past claims. Instead, insurance companies spread costs across all of their policyholders. This is one reason why shopping for a lower premium can make good financial sense, even if your health has remained unchanged.

5. You Can Replace Your Medicare Supplement Year-Round

Unlike Medicare Advantage and Part D prescription drug plans, Medicare Supplement replacement is available any time of the year. There is no annual enrollment period required to switch Medicare Supplement companies.

You can apply for a new Medicare Supplement policy whenever you choose. In most cases, you’ll answer a series of health questions on the application, but no medical exam is required. The underwriting process generally focuses on identifying more serious medical conditions rather than routine health issues.

In the next section, we’ll explain what insurance companies look for during underwriting and how to determine whether you’re likely to qualify for a lower premium.

Medicare Supplement Replacement – Application & Health Prescreening

When switching your Medicare Supplement, it’s important to understand that Medigap insurance companies will perform medical underwriting before approving your application. This means that during the Medicare Supplement replacement process, you’ll need to complete a health questionnaire. This is different than your initial Medicare Supplement Open Enrollment Period—when you can generally enroll without answering health questions.

Keep in mind that there is no medical exam, just some questions. And, it’s best not to let the health underwriting process discourage you as most people will qualify. It’s better to check and be certain rather wonder what may have happened.

In most cases Medicare Supplement insurers are screening for what are considered to be more serious medical conditions. Some of the most common ones include:

Pending or scheduled diagnostic testing, medical treatment, or surgery.
Diabetes with complications, including cardiovascular disease, retinopathy, neuropathy, or kidney disease.
A heart attack, atrial fibrillation, heart surgery, stroke, or other major cardiovascular event within the past two years. Many carriers become more flexible once two years have passed, depending on your overall health.
Cancer diagnosed or treated within the past two years (non melanoma skin cancers are ok).
COPD or emphysema requiring oxygen therapy.
Chronic kidney disease, especially if dialysis is required.
Other serious or unstable medical conditions that may affect underwriting.

This is not a complete list of medical conditions that may impact your eligibility for a replacement Medigap policy. Health underwriting guidelines vary from one insurance company to another, and many applicants who don’t qualify with one carrier may still qualify with another.

The best way to determine whether you’re eligible for a Medicare Supplement replacement is to speak with an experienced Medicare advisor before submitting an application. We understand the underwriting guidelines of many leading insurance companies and can often recommend carriers that are the best fit for you. Even if you aren’t eligible today, we can explain what to expect, discuss your options, and help you determine if and when you may qualify in the future.

Medicare Supplement Replacement – Frequently Asked Questions

Will my new Medicare Supplement insurer approve and pay claims the same as my current insurer?

Yes. One of the biggest advantages of a Medicare Supplement (Medigap) policy is that benefits are standardized by the federal government. If you purchase the same plan letter (such as Plan G or Plan N), your benefits remain exactly the same regardless of which insurance company provides the policy.

Medicare processes and approves your medical claims first. Once Medicare pays its portion, your new Medicare Supplement insurer is required to pay its share according to your plan’s standardized benefits. This means a Medicare Supplement replacement does not change the benefits or claims approval you receive—it simply changes the insurance company providing your coverage.

Will my doctors and medical providers accept my new Medicare Supplement policy?

Yes. One of the primary benefits of a Medigap policy is the freedom to see any doctor or medical provider nationwide that accepts Medicare. Since providers bill Medicare first, they do not distinguish between Medicare Supplement insurance companies.

When you complete a Medicare Supplement replacement, you can continue seeing the same doctors and specialists without changing your healthcare providers.

Will my new Medicare Supplement cover my pre-existing conditions?

Yes, your new Medicare Supplement insurer will cover your pre-existing conditions. In rare cases an insurer may have a short waiting period (3 – 6 months) to cover pre-existing conditions, however, only if you have not maintained coverage. If you’ve had coverage, particularly through your current Medicare Supplement, there is not waiting period.

Will my deductibles and out-of-pocket costs increase if I replace my Medicare Supplement policy?

Not necessarily. A Medicare Supplement replacement does not automatically increase your deductibles or out-of-pocket costs. Your costs depend on which Medicare Supplement plan you choose. For example, if you replace Medicare Supplement Plan G with another Plan G, your benefits and deductibles remain exactly the same because all Medigap plans are standardized by the federal government. The same is true if you replace Plan F with another Plan F or Plan N with another Plan N. However, if you change from one plan letter to another—such as from Plan G to Plan N—your out-of-pocket costs may change based on the benefits of the new plan.

Will my premiums increase with my new policy over time?

Yes. Premium increases are normal across all Medicare Supplement plans, regardless of the insurance company. Rates generally rise due to higher healthcare costs from inflation and increased claims costs incurred by the insurer.

The goal of a Medicare Supplement replacement is to reduce your premium today by moving to a comparable (or exact same) policy with a lower monthly cost. Even if future rate increases occur, starting with a lower premium can result in substantial long-term savings.

Can I replace my Medicare Supplement again in the future?

Yes. If you qualify medically, you can complete another Medicare Supplement replacement whenever a better value becomes available. The process is similar each time—you complete a brief health pre-qualification, compare available plans, and apply with a new insurer if it makes financial sense.

We recommend reviewing your Medicare Supplement coverage every two to three years. Premiums change regularly, and periodic reviews can help ensure you’re still receiving competitive rates. As our client, we’ll proactively remind you when it’s a good time to compare your options and determine whether another Medigap replacement could save you money.

Medicare Supplement (Medigap) Plans & Coverage

Medicare Supplement plans, also known as Medigap plans, are standardized and identified by letter, with each letter representing a different level of coverage. Every Medicare Supplement plan works alongside Original Medicare (Parts A and B) by helping pay deductibles, copayments, and coinsurance that Medicare doesn’t fully cover. The specific Medicare Supplement plan you choose determines how much of those out-of-pocket costs you’ll be responsible for.

While there are several Medicare Supplement plans available, most beneficiaries choose from three popular options: Medicare Supplement Plan G, Medicare Supplement Plan N, and Medicare Supplement Plan F. Plan F is only available if you started Medicare Part A prior to January 1st, 2020. In recent years, this has caused Plan G and Plan N to take the lead as the two most popular options. Each plan offers a different balance of coverage and monthly premium, allowing you to select the option that best fits your healthcare needs and budget. The comparison chart below highlights the benefits and coverage differences between Plan F, Plan G, and Plan N, making it easier to determine which Medicare Supplement plan may be right for you.

Medicare Supplement Plan Descriptions

Medicare Supplement Plan G

Medicare Supplement Plan G is the most popular of all Medicare Supplement plans because it offers comprehensive coverage with predictable out-of-pocket costs. Plan G pays all Medicare Part A and Part B deductibles, coinsurance, and copayments except for the annual Medicare Part B deductible, which is $285 in 2026.

After you have met the Part B deductible for the year, Medicare Supplement Plan G covers 100% of Medicare-approved expenses. This means you generally won’t have additional deductibles, copayments, or coinsurance for covered services, making Plan G an excellent choice for beneficiaries who want extensive coverage without paying the higher premiums often associated with Plan F.

Medicare Supplement Plan N

Medicare Supplement Plan N is often considered the value Medicare Supplement plan, combining strong coverage with lower monthly premiums. Like Plan G, Plan N requires you to pay the annual Medicare Part B deductible, which is $285 in 2026.

After you’ve met the deductible, Plan N covers most Medicare-approved expenses, but you’ll generally pay small copayments for certain doctor visits and emergency room visits. Unlike Medicare Supplement Plan G or Plan F, Plan N not cover Medicare Part B “excess charges.” These charges can occur when a healthcare provider bills more than the Medicare-approved amount. Excess charges are relatively uncommon and are often modest when they do occur.

For Medicare beneficiaries who don’t mind paying some extra copays in exchange for lower monthly premiums, Medicare Supplement Plan N can provide significant long-term savings while still offering excellent protection against major healthcare expenses.

Medicare Supplement Plan F

Medicare Supplement Plan F offers the most comprehensive coverage of all Medicare Supplement plans, paying 100% of Medicare Part A and Part B deductibles, coinsurance, and copayments for Medicare-approved services. With Plan F, eligible beneficiaries typically have little to no out-of-pocket medical expenses after paying their monthly premium.

However, Medicare Supplement Plan F is only available to individuals who became eligible for Medicare before January 1, 2020. If you became eligible for Medicare on or after that date, Plan F is no longer available for purchase. Fortunately, Medicare Supplement Plan G provides nearly identical coverage, making it the most popular alternative. In fact, many beneficiaries who were eligible for Plan F have voluntarily switched to Plan G to reduce their monthly premiums while maintaining nearly the same level of protection.
