What Are These Two Plan Types, Really?
It's easy to get these two confused because they are both offered by private insurance companies and have 'Medicare' in the name. But they work in fundamentally different ways.
A Medigap plan, also called a Medicare Supplement, is insurance that works alongside Original Medicare (Part A and Part B). Think of it as gap-filler insurance. When you have a medical service, Medicare pays its share first, and then your Medigap plan pays its share, which can be some or all of the remaining deductibles, copayments, and coinsurance. You pay a separate monthly premium for the Medigap plan in addition to your Part B premium. The key feature is that a Medigap plan has no network; you can see any doctor or visit any hospital in the United States that accepts Medicare. The benefits of each plan letter (like Plan G or Plan N) are standardized by the federal government, so a Plan G from one company has the same core medical benefits as a Plan G from another.
A Medicare Advantage plan, sometimes called Part C, is a complete replacement for Original Medicare. You are still in the Medicare program, but a private insurance company manages all of your Part A and Part B benefits. Most of these plans also include prescription drug coverage (Part D), so you have everything bundled into one card and one plan. In exchange for often very low or even zero-dollar monthly premiums, you agree to use a specific network of doctors and hospitals and pay copayments or coinsurance for most services as you use them. These plans also have an annual maximum out-of-pocket limit, which protects you from catastrophic costs.
Side-by-Side: A Comparison for Cleveland Heights Residents
Let's break down the key differences that matter most to our clients here in Cleveland Heights and the surrounding communities of Shaker Heights and University Heights.
Cost Structure: With Medigap, you have a higher, predictable monthly cost. You pay your Part B premium and your Medigap premium every month, but when you receive care, you'll have very few, if any, out-of-pocket costs for Medicare-covered services. With Medicare Advantage, your monthly cost is often much lower (sometimes $0), but your out-of-pocket costs are variable. You'll pay copays for doctor visits, hospital stays, and specialist care up to the plan's annual maximum. The 2026 Part B deductible must be met before Medigap coverage for services kicks in, while many Advantage plans have their own separate deductibles.
Doctor & Hospital Choice: This is the biggest philosophical difference. A Medigap plan gives you the freedom to see any provider nationwide who accepts Medicare. No referrals are needed to see specialists. For Medicare Advantage plans, you must use a provider network (like an HMO or PPO). If you go out-of-network for non-emergency care, you could pay much more, or the service may not be covered at all. So, if you're considering an Advantage plan, it is absolutely essential to verify that your specific doctors at University Hospitals Cleveland Medical Center, for example, are in the plan's network for the coming year.
Prescription Drugs: Medigap plans do not include prescription drug benefits. You must purchase a separate, standalone Part D prescription drug plan. Most Medicare Advantage plans bundle drug coverage directly into the plan (these are called MA-PDs).
Extra Benefits: To be competitive, Medicare Advantage plans often include extra benefits not covered by Original Medicare. This can include routine dental, vision, and hearing coverage, as well as gym memberships and allowances for over-the-counter health items. Medigap plans do not offer these built-in extras.
Who Tends to Choose a Medigap Plan?
Over the years, after helping thousands of Northeast Ohio families, we've seen a clear profile of the person who feels most comfortable with a Medigap plan. This person values predictability and freedom of choice above all else. They are willing to pay a higher monthly premium in exchange for knowing that if a major health issue arises, they will have minimal out-of-pocket expenses. They don't want to worry about networks or getting referrals to see a specialist.
This is often the choice for individuals with chronic health conditions who see multiple specialists, as they can coordinate their own care team without network restrictions. It's also a popular choice for 'snowbirds'—the many Ohioans who spend winters in states like Florida or Arizona. With a Medigap plan, their coverage travels with them seamlessly; they can see a doctor in Sarasota just as easily as they can in Cleveland Heights.
Consider a 68-year-old retired railroad worker from University Heights. His cardiologist is based at University Hospitals, but he wants a second opinion from a specialist at a clinic in another state. With Medigap, he can make that appointment without asking for permission from an insurance company. He understands he pays for this flexibility with his monthly premium, and for him, that trade-off is well worth it. He has a Plan G, so after his annual Part B deductible is met, his medical bills for Medicare-approved services are covered at 100%.

When Does a Medicare Advantage Plan Make Sense?
A Medicare Advantage plan is often a great fit for people who are focused on keeping their fixed monthly costs as low as possible. If you are generally healthy, don't take many expensive prescriptions, and don't mind using a provider network, the value proposition of a zero-dollar premium plan can be very appealing. The money saved on monthly premiums can be used for other living expenses.
The bundled-in extra benefits are a major draw. For many, having routine dental cleanings, an allowance for eyeglasses, and a gym membership included in their health plan simplifies their lives and budgets. They see it as getting more for their Medicare benefits. The key is that they must be comfortable with the network model and the pay-as-you-go system of copayments and coinsurance.
Let's imagine a 65-year-old who just sold his small business in the Coventry Village area and is watching his budget. All of his trusted doctors are already in the network of a prominent local Medicare Advantage plan. He's in good health and likes the idea of not paying a monthly plan premium. The plan includes a SilverSneakers membership he can use at the Cleveland Heights Community Center and a quarterly allowance for over-the-counter items like vitamins and aspirin. He understands that if he needs a hospital stay, he'll have a daily copay, but he's comfortable with that risk in exchange for the low upfront cost and extra perks.
The Fine Print: Switching Rules & Guarantee Issue Rights
This is perhaps the most important part of the decision, because a choice you make at 65 can have consequences for years to come. The rules for joining and leaving these plans are not symmetrical.
When you first turn 65 and enroll in Medicare Part B, you enter your one-time Medigap Open Enrollment Period. This is a six-month window where you have a 'guaranteed issue right.' This means any Medigap company must sell you any plan they offer, regardless of your health history. They cannot charge you more or deny you coverage because of pre-existing conditions. If you miss this window and try to apply for a Medigap plan later, you will likely have to answer health questions (a process called medical underwriting), and you can be denied.
Medicare Advantage plans have different rules. You can enroll in one when you're new to Medicare. After that, you can switch from one Advantage plan to another, or from Original Medicare to an Advantage plan, every year during the Annual Enrollment Period (AEP) from October 15th to December 7th. This provides annual flexibility.
The critical pitfall to avoid is what we call the 'Medigap trap.' Someone might start with a Medigap plan at 65, then at age 70, switch to a $0 premium Advantage plan to save money. If, at age 75, they develop a serious health condition and want the stability of their old Medigap plan back, they may not be able to get it. They would have to pass medical underwriting, and the new health condition could cause them to be denied. This is why the initial choice at 65 is so weighty. While government resources like the Western Reserve Area Agency on Aging—OSHIIP office in Cleveland provide excellent neutral education, and the SSA office on E 9th St handles Part A and B enrollment, they don't give plan-specific advice. Discussing these long-term implications is a vital part of our process.

Frequently asked questions
Can I have both a Medigap plan and a Medicare Advantage plan at the same time?
No, it is illegal for an insurance company to sell you a Medigap policy if they know you have a Medicare Advantage plan. You must choose one path or the other. Medigap supplements Original Medicare, while Medicare Advantage replaces it. Having both would be redundant and is not permitted.
Do I still have to pay my Medicare Part B premium with these plans?
Yes, you must continue to pay your monthly Medicare Part B premium to the government regardless of which option you choose. This is a common point of confusion. Think of the Part B premium as your ticket to the Medicare system. Both Medigap and Medicare Advantage plans are built upon that foundation.
What if my doctor leaves my Medicare Advantage plan's network?
If your doctor leaves your plan's network mid-year, it can be disruptive. In certain circumstances, this may grant you a Special Enrollment Period (SEP) to switch to a different plan. However, your main opportunity to change plans is during the Annual Enrollment Period (AEP) from October 15 to December 7. This is why it's crucial to review your plan's network every single year.
If Medigap doesn't cover drugs, how do I get prescription coverage?
You are correct, Medigap plans do not include prescription drug benefits. To get coverage for your medications, you will need to enroll in a separate, standalone Medicare Part D prescription drug plan. You purchase this from a private insurance company and pay a separate monthly premium for it, in addition to your Part B and Medigap premiums.
Are all Medigap Plan Gs the same? The prices are different.
Yes, the core medical benefits of a Medigap Plan G are standardized by the federal government. A Plan G from Company X offers the exact same coverage for hospital and doctor bills as a Plan G from Company Y. The only differences are the monthly premium the company charges and their customer service reputation. This is why price shopping among reputable carriers is so important for Medigap.
I live in Cleveland Heights but travel. Am I covered?
With Medigap and Original Medicare, you are covered anywhere in the United States and its territories, as long as the provider accepts Medicare. With a Medicare Advantage plan, it's more complicated. Emergency and urgent care are always covered nationwide, but for routine care, you are typically restricted to your plan's local network. Some PPO plans offer out-of-network benefits at a higher cost, but HMOs generally do not.
