What is Medicare Supplement Plan G?
Medicare Supplement Plan G, often called Medigap Plan G, is the most comprehensive coverage available to individuals new to Medicare today. Think of Original Medicare (Part A and Part B) as your primary insurance. It covers a lot, but leaves you with deductibles, coinsurance, and copayments. A Medigap plan is secondary insurance you buy from a private company to fill those gaps. Plan G is known for its simplicity and predictability. Once you pay your monthly premium for the plan, its job is to cover nearly all of your remaining Medicare-approved costs. The only significant out-of-pocket expense you're responsible for is the annual Medicare Part B deductible. In 2026, this deductible is projected to be around a few hundred dollars for the entire year. After you meet that single deductible, Plan G pays its share, which includes the 20% coinsurance for doctor visits, outpatient services, and durable medical equipment. It also covers your Part A hospital deductible, skilled nursing facility costs, and even pays for Part B excess charges, a detail we'll discuss more later. For Ohioans who want to budget with certainty and avoid surprise medical bills, Plan G is a very popular choice.
And What About Medicare Supplement Plan N?
Medicare Supplement Plan N is a close cousin to Plan G. It offers a very similar level of robust coverage but includes a few cost-sharing components in exchange for a lower monthly premium. Like Plan G, you are still responsible for paying the annual Part B deductible first. After that, Plan N covers the 20% coinsurance just like Plan G does, but with two key exceptions. First, you may have a copay of up to $20 for some doctor's office visits. Second, if you visit the emergency room and are not admitted to the hospital, you could have a copay of up to $50. These small, predictable copayments are the primary way Plan N keeps its premiums lower than Plan G's. There is one other crucial difference: Plan N does not cover Part B excess charges. An excess charge can occur if you see a provider who does not accept the Medicare-approved amount as full payment. While this is not common in Ohio, it is a possibility. For many folks, the monthly premium savings of Plan N are worth taking on these potential small costs. It's a plan designed for people who are comfortable with minor, predictable cost-sharing to reduce their fixed monthly expenses.
Plan G vs. Plan N: A Side-by-Side Breakdown
When you put these two plans head-to-head, the differences become clear. Let's compare them across the factors that matter most to our Northeast Ohio clients.
Monthly Premiums: Plan N premiums are consistently lower than Plan G premiums, sometimes by $25 to $50 per month, depending on your age, gender, and location. This is the main attraction of Plan N. Over a year, this can add up to several hundred dollars in savings.
Annual Deductible: Both plans require you to pay the annual Medicare Part B deductible yourself. There is no difference here. Once you've paid that amount out-of-pocket for Part B services, your supplement begins to pay.
Cost-Sharing: This is the major divergence. With Plan G, after your deductible is met, you have no further copays or coinsurance for Medicare-approved services. Your costs are fixed. With Plan N, after your deductible, you may have copays of up to $20 for office visits and up to $50 for ER visits that don't result in an admission. If you see doctors infrequently, these costs may be minimal. If you have multiple specialist appointments, they could add up.
Part B Excess Charges: This is the other key difference. Plan G covers these charges, which can be up to 15% above the Medicare-approved amount. Plan N does not cover them, meaning if you incurred one, you would have to pay it yourself. While these charges are not frequent in Ohio, Plan G provides total protection against them, whereas Plan N does not.
Who Is Plan G Best For? Ohio Scenarios
Plan G is an ideal fit for the individual who values maximum financial predictability and minimal hassle. If your goal is to pay a monthly premium and essentially eliminate any other billing paperwork or surprise costs for Medicare-approved care, Plan G delivers. After meeting the one-time Part B deductible each year, you can see any doctor or visit any hospital that accepts Medicare in the country without worrying about copays or coinsurance.
A perfect example is a 68-year-old retired small-business owner from Mentor. He sees a cardiologist at University Hospitals and a pulmonologist for regular check-ups. With multiple visits a year, the thought of paying a copay each time feels like a nuisance. He also spends a few winter months in Florida and wants the assurance that he won't encounter a doctor who bills for excess charges while away from his usual Ohio network. For him, paying a slightly higher monthly premium for Plan G is a fair price for the convenience and comprehensive coverage. He can budget for his premium and the single deductible, and that's it. It simplifies his financial life and allows him to focus on his health, not on medical bills.

Who Is Plan N A Good Fit For? Ohio Scenarios
Plan N is an excellent choice for the budget-conscious Medicare beneficiary who is in relatively good health and doesn't mind some minimal cost-sharing. If you look at the potential for $20 office visit copays and see it as a reasonable trade-off for a lower, guaranteed monthly premium, Plan N is worth serious consideration. This person understands that they are taking on a small amount of risk (copays and the potential for excess charges) in exchange for tangible premium savings each month.
Consider a 65-year-old former secretary from Parma who is moving onto Medicare for the first time. She has a trusted primary care doctor she sees once or twice a year for preventative care. She checked, and her doctor accepts Medicare assignment, meaning excess charges are not a concern there. Saving $30 a month on her supplement premium makes a real difference in her monthly budget. She is comfortable with the idea that if she needs to see a specialist or visit the ER, she might have a small copay. For her, the math works out. The premium savings far outweigh the potential out-of-pocket costs she anticipates. Plan N allows her to get nearly the same strong foundational coverage as Plan G while keeping more money in her pocket each month.
The Fine Print: Part B Excess Charges in Ohio
The topic of Part B excess charges is often the final sticking point for people deciding between Plan G and Plan N. It sounds complicated, but the concept is straightforward. The federal government sets an approved amount that Medicare will pay for any given medical service. Most doctors in the United States agree to accept this amount as full payment; this is called "accepting Medicare assignment." However, a doctor can choose not to accept assignment. In that case, they are legally allowed to bill you for up to 15% more than the Medicare-approved amount. This extra 15% is the "excess charge."
Here in Ohio, the good news is that the overwhelming majority of doctors and hospital systems, including major ones like Cleveland Clinic and Summa Health, accept Medicare assignment. This makes encountering an excess charge a relatively rare event for most residents. It's more likely to be a factor if you see a niche specialist or if you travel to other states where provider participation rules might differ. So, the decision boils down to your personal risk tolerance. Choosing Plan G means you are paying a higher premium for insurance against this risk, no matter how small. Choosing Plan N means you are accepting this small risk in order to realize definite premium savings every month. There is no right or wrong answer, only the one that aligns with your personal and financial outlook.
Switching Plans and Your Enrollment Window
Choosing between Plan G and Plan N is a significant decision, partly because it can be difficult to change your mind later. When you first become eligible for Medicare Part B at age 65, you get a six-month Medigap Open Enrollment Period. During this window, you can buy any Medigap plan sold in Ohio from any company, and they cannot use medical underwriting. This means they cannot ask you health questions, charge you more because of your health history, or deny you coverage. This is your one golden ticket to enroll without scrutiny.
After this period ends, things change. If you choose Plan N and a few years later your health changes and you want the more comprehensive coverage of Plan G, you would likely have to apply and answer a full slate of health questions. The insurance company could then charge you a higher rate or even deny your application altogether based on your health conditions. This is why it's so important to consider your potential future needs, not just your current health, when making the initial choice. While some states have rules that make it easier to switch, Ohio does not. The choice you make during your initial enrollment period is a lasting one. Weighing the long-term implications of premiums versus potential out-of-pocket costs is vital. The best way to sort through these details for your specific situation is to talk it through.

Frequently asked questions
Do Medicare Supplement Plan G and Plan N cover prescription drugs?
No, they do not. This is a common point of confusion. Medigap plans, including G and N, are designed only to supplement Original Medicare (Part A and Part B). They do not offer coverage for prescription drugs you pick up at the pharmacy. For that, you will need to enroll in a separate, standalone Medicare Part D Prescription Drug Plan. We have helped thousands of Ohio families pair the right Part D plan with their Medigap plan to ensure they have comprehensive medical and drug coverage.
Can my premium for Plan G or Plan N increase over time?
Yes, it is very likely that your Medigap premium will increase over time. Premiums can rise for two main reasons: inflation in healthcare costs and your age. Most plans in Ohio are 'attained-age rated,' which means the premium is based on your current age and will increase as you get older. It's important to ask about a company's rate increase history when choosing a plan, as this can be just as important as the initial premium you are quoted.
If excess charges are rare in Ohio, why would anyone buy Plan G?
There are three main reasons. First, for total predictability. With Plan G, after the Part B deductible, your Medicare costs are $0. There are no copays to track for doctor visits. Second, for people who travel. If you spend significant time outside Ohio, you may encounter providers who don't accept Medicare assignment, making excess charges more likely. Plan G provides protection anywhere in the U.S. Finally, some people simply don't want to worry about any 'what-ifs' and are willing to pay a little more for that assurance.
Is the network of doctors different for Plan G and Plan N?
No, the network is exactly the same, and this is a major benefit of all Medigap plans. Unlike Medicare Advantage plans which have defined provider networks, a Medigap plan works with Original Medicare. This means you can see any doctor or go to any hospital in the United States that accepts Medicare. The insurance company for your Plan G or Plan N cannot dictate which doctors you see. As long as your provider accepts Medicare, your supplement will pay its share.
What if I choose Plan N and end up needing the emergency room frequently?
This is a valid consideration. The up-to-$50 emergency room copay on Plan N applies each time you visit the ER and are not admitted as an inpatient. If you have a chronic condition that results in frequent ER visits, these copays could add up and potentially offset the monthly premium savings you get with Plan N. It is one of the key calculations to make when comparing it with Plan G, which has a $0 copay for ER visits after you've met your Part B deductible.
Where can I find unbiased Medicare information besides an agency?
For completely free and official government counseling, the best resource in Ohio is the Ohio Senior Health Insurance Information Program, or OSHIIP. They have trained volunteers who can explain how Medicare works in general terms. For questions specifically about your Social Security benefits or enrolling in Part A and Part B, you should contact your local Social Security Administration (SSA) field office. These resources provide excellent foundational knowledge. Our role as an agency is to help you apply that knowledge by comparing the specific private plan options and rates available in your Northeast Ohio ZIP code.
