Medigap Plan N vs G: Key Differences for 2026

Choosing between Medigap Plan N and Plan G is one of the most important decisions you will make when enrolling in Medicare. Both plans offer strong coverage for gaps left by Original Medicare, but their cost structures and out-of-pocket rules differ significantly. Understanding these differences can save you hundreds or even thousands of dollars each year. This article breaks down every aspect of Medigap Plan N vs G so you can pick the right plan for your health needs and budget.

How Medigap Plan N and Plan G Compare at a Glance

Medigap Plan G and Plan N both cover Medicare Part A coinsurance and hospital costs up to an additional 365 days after Medicare benefits are exhausted. They also cover Part B coinsurance or copayment, blood (first three pints), and hospice care coinsurance or copayment. However, the key differences lie in how they handle Part B excess charges and copayments for doctor visits and emergency room visits.

Plan G covers Medicare Part B excess charges in full. These excess charges occur when a provider does not accept Medicare assignment and bills you up to 15 percent more than the Medicare-approved amount. Plan N does not cover Part B excess charges at all. If you see a provider who does not accept assignment, you are responsible for the full excess amount plus any standard copayments.

Additionally, Plan N requires copayments for certain services. You pay up to $20 for some office visits and up to $50 for emergency room visits that do not result in inpatient admission. Plan G has no such copayments. This difference in cost-sharing is the main reason why Plan N premiums are typically lower than Plan G premiums.

Monthly Premiums and Long-Term Costs

Premiums for Medigap Plan N are generally 15 to 30 percent lower than Plan G premiums in most states. For a 65-year-old nonsmoker, Plan N might cost around $100 to $140 per month, while Plan G could range from $140 to $200 per month. These numbers vary by insurer, location, and gender, but the pattern is consistent nationwide.

However, lower premiums do not always mean lower total costs. You must factor in the copayments Plan N requires. If you visit a primary care doctor four times a year and have one emergency room visit that does not lead to admission, you could pay $80 to $130 in copayments annually under Plan N. If your Plan G premium is $50 more per month, that is $600 more per year. The math often favors Plan N for healthy individuals who rarely need medical care.

But if you have chronic conditions or frequently see specialists, those copayments add up quickly. In our guide on Medigap Plan G Cost 2026: What You Will Pay, we explain how premium increases and out-of-pocket expenses can affect your annual budget. It is essential to compare your expected healthcare usage against the premium difference to determine which plan offers better value.

Coverage for Doctor Visits and Emergency Room Care

This is where Plan N and Plan G diverge most clearly in day-to-day use. Under Plan G, once you meet your Part B deductible ($185 in 2026), Medicare pays its share and Plan G covers the rest. You pay nothing for covered services at the point of care. Under Plan N, you pay a copayment for each office visit and each emergency room visit that does not result in inpatient admission.

• Office visit copayment: You pay up to $20 per visit under Plan N. Plan G charges nothing.
• Emergency room copayment: You pay up to $50 under Plan N if you are not admitted to the hospital. Plan G charges nothing.
• Part B excess charges: Plan G covers them fully. Plan N does not cover them at all.
• Part B deductible: Both plans require you to pay the $185 deductible before coverage kicks in (for plans purchased after 2020).

For people who rarely visit the doctor, the copayments under Plan N may be negligible. But if you manage a chronic condition like diabetes or heart disease, multiple specialist visits each month could make Plan G more economical despite its higher premium.

Part B Excess Charges: A Hidden Risk

Part B excess charges are a critical factor in the Medigap Plan N vs G debate. Under Original Medicare, doctors and suppliers can choose whether to accept assignment. If they do accept assignment, they agree to charge no more than the Medicare-approved amount. If they do not accept assignment, they can charge up to 15 percent more. This is called an excess charge.

Plan G covers these excess charges entirely. Plan N does not cover them at all. If you live in a state where many doctors do not accept assignment, or if you travel frequently and see out-of-network providers, Plan N could leave you with surprise bills. For example, a $1,000 Medicare-approved procedure could cost you $1,150 if the doctor does not accept assignment. Under Plan G, that extra $150 is covered. Under Plan N, you pay it out of pocket.

States like California, New York, and Ohio have laws that prohibit or limit excess charges, but most states allow them. If you live in a state without such protections, Plan G provides valuable peace of mind.

Enrollment Timing and Medical Underwriting

The best time to buy any Medigap plan is during your Medigap Open Enrollment Period. This six-month window begins the month you turn 65 and enroll in Medicare Part B. During this period, insurers cannot deny you coverage or charge higher premiums based on pre-existing conditions. After this window closes, you may face medical underwriting, which means insurers can reject your application or charge significantly higher rates based on your health history.

If you are still within your open enrollment period, you can choose either Plan N or Plan G without worrying about health questions. If you are outside that window, switching from Plan N to Plan G later may be difficult or expensive if your health has changed. This is a major reason to choose carefully from the start.

Some people choose Plan N initially because of the lower premium, then later want to switch to Plan G due to unexpected medical needs. That switch may not be possible without underwriting. It is often wiser to choose the more comprehensive plan (Plan G) at the outset if you can afford the premium difference, especially if you have any chronic conditions or family history of illness.

Which Plan Is Better for Frequent Travelers

If you travel frequently within the United States, Plan G offers better protection because it covers Part B excess charges wherever you go. If you see an out-of-network doctor in another state, you could face excess charges under Plan N. Plan G also covers foreign travel emergency care at 80 percent of the cost after a $250 deductible, up to a lifetime maximum of $50,000. Plan N covers foreign travel emergency care under the same terms.

Both plans provide the same foreign travel coverage, so that is not a differentiator. The key difference for travelers is the excess charge protection. If you spend winters in Florida or Arizona and see local doctors who may not accept assignment, Plan G is the safer choice.

Provider Networks and Freedom of Choice

Both Medigap Plan N and Plan G allow you to see any doctor or specialist who accepts Medicare. There are no networks to worry about. This is one of the biggest advantages of Medigap over Medicare Advantage plans. You can go to any hospital or doctor in the country that accepts Medicare, without referrals or prior authorization.

However, Plan N introduces a small friction point: the copayment. Even though you can see any Medicare-accepting provider, you will pay $20 per office visit. For some people, this is a minor inconvenience. For others, especially those with multiple chronic conditions, it adds up. Plan G removes all friction at the point of care.

If you value simplicity and predictability, Plan G is the clear winner. If you are comfortable with occasional copayments and want to save on monthly premiums, Plan N may be a good fit.

Frequently Asked Questions

Can I switch from Plan N to Plan G later?

You can switch at any time, but after your Medigap Open Enrollment Period ends, you will likely need to pass medical underwriting. If you develop a health condition, you could be denied or charged a much higher premium. It is best to choose the plan that fits your long-term needs from the start.

Does Plan N cover the Part B deductible?

No. For plans purchased after 2020, both Plan N and Plan G require you to pay the Medicare Part B deductible out of pocket. In 2026, that deductible is $185 per year. After you meet it, Plan G covers all remaining Part B coinsurance and copayments, while Plan N covers most but still requires the office visit and ER copayments.

Which plan is more popular among beneficiaries?

Plan G is currently the most popular Medigap plan in the United States, followed by Plan N. Plan G’s comprehensive coverage and predictable costs appeal to people who want maximum protection. Plan N attracts cost-conscious beneficiaries who are willing to accept copayments in exchange for lower premiums.

Are there states where Plan N is better than Plan G?

In states that prohibit Part B excess charges, Plan N becomes more attractive because the biggest risk of Plan N is eliminated. Those states include Connecticut, Massachusetts, Minnesota, New York, Ohio, Pennsylvania, Rhode Island, and Vermont. In these states, Plan N’s lower premium may outweigh the lack of excess charge coverage.

Does Plan N cover preventive care?

Yes. Both plans cover all Medicare-approved preventive services at no cost to you, as long as you see a provider who accepts Medicare assignment. This includes annual wellness visits, cancer screenings, and vaccinations. The copayments under Plan N do not apply to preventive services.

Making Your Final Decision

When comparing Medigap Plan N vs G, start by looking at your budget and your health. If you can afford the higher premium for Plan G, it offers the most comprehensive and worry-free coverage. You will never face a surprise copayment or excess charge. For those who want to save money each month and do not mind paying small fees at the doctor’s office, Plan N is a solid alternative.

Also consider your state’s rules on excess charges and your travel habits. If you live in a state that prohibits excess charges, Plan N becomes more appealing. If you travel often or live in a state where doctors frequently balance bill, Plan G is the safer bet.
