Medicare Supplement Plan G vs Plan N: Which Covers More in 2026?
⏱ 13 min read · 2,610 words
If you've enrolled in Original Medicare and started looking at Medigap policies, you've probably noticed that Plan G and Plan N dominate the recommendations. They're the two most popular supplement options in 2026, but they work differently and most people assume the higher premium automatically means better coverage.
That's not quite right.
Plan G does cover more out-of-pocket costs than Plan N. But Plan N's lower monthly premium can save you $20 to $50 every month, and for some people, those savings outweigh the extra copays. The question isn't which plan is objectively better. It's which one makes sense for how often you actually go to the doctor.
This article will walk through exactly what each plan covers, what you'll pay out of pocket, and how to figure out which one saves you more money over the course of a year.
Why Choosing Between Medigap Plans Feels Harder Than It Should
When I first helped my sister compare Medigap options after she turned 65, she handed me a chart with 10 different plan letters and said, "Just tell me which one to pick." I couldn't do that without asking her a few questions first.
The reason this decision feels unnecessarily complicated is that the names don't tell you anything useful. Plan G and Plan N sound like arbitrary labels, and the brochures all use the same insurance jargon. Most people end up picking based on which agent calls them first or which plan their neighbor has, neither of which is a good way to make a financial decision that will last for years.
Here's the other problem: most online guides compare all 10 Medigap plans at once, which buries the information you actually need. For most people turning 65 in 2026, the real choice comes down to two options. Plan G and Plan N. Plan F used to be the most comprehensive, but it's no longer available to anyone who became eligible for Medicare after January 1, 2020. If you're reading this, Plan F is off the table.
Medicare Supplement Plan G vs Plan N Comparison: What Each Plan Covers
Both Plan G and Plan N cover the big gaps in Original Medicare. That includes your Part A coinsurance for hospital stays beyond 60 days, your Part B coinsurance (the 20% Medicare doesn't pay), and the first three pints of blood each year. Both plans also include foreign travel emergency coverage, which pays 80% of medically necessary care if you get sick or injured outside the United States.
Here's where they split.
Plan G covers:
- Part B deductible: Not covered. You pay the first $257 out of pocket in 2026 before Plan G kicks in.
- Part B excess charges: Fully covered. If a doctor charges more than Medicare's approved amount (rare, but it happens), Plan G pays the difference.
- Doctor visit copays: None. Once you've met the Part B deductible, Plan G covers 100% of your Part B coinsurance with no copays.
- Emergency room visits: Fully covered after you meet the Part B deductible. No copay.
Plan N covers:
- Part B deductible: Not covered. You pay the same $257 out of pocket.
- Part B excess charges: Not covered. You'd pay the difference if a doctor bills above Medicare's approved rate.
- Doctor visit copays: Up to $20 per visit. This applies to office visits, not other outpatient services.
- Emergency room visits: Up to $50 per visit, but the copay is waived if you're admitted to the hospital.
Most people assume Plan N's copays apply to everything. They don't. The $20 copay is only for doctor office visits. If you have lab work, an X-ray, physical therapy, or outpatient surgery, there's no copay under Plan N it works the same as Plan G once you've paid the Part B deductible.
How the Premium Difference Adds Up Over a Year
The single biggest factor in choosing between these two plans is the monthly premium difference in your area. Plan N premiums are typically $20 to $50 lower per month than Plan G, though the exact gap depends on your age, gender, zip code, and which insurance company you're comparing.
Take someone who lives in a mid-sized city and gets quoted $145/month for Plan N and $180/month for Plan G. That's a $35 monthly difference, or $420 per year.
Now add in Plan N's copays. If this person sees their primary care doctor four times a year and has one trip to the emergency room that doesn't result in admission, they'd pay:
- Four office visits: $20 × 4 = $80
- One ER visit: $50 × 1 = $50
- Total copays: $130/year
Even after paying $130 in copays, Plan N still saves them $290 compared to Plan G ($420 premium savings minus $130 in copays). For someone who sees the doctor less often say, twice a year with no ER visits. Plan N saves even more.
But if you're managing multiple chronic conditions and seeing specialists every month, the math tilts the other way. Ten office visits under Plan N means $200 in copays. Add a couple of ER visits, and suddenly Plan G's higher premium starts to look like the better deal.
What About Part B Excess Charges?
This is the coverage difference that gets the most attention in Medigap comparisons, and it's worth a lot less than most people think.
Part B excess charges happen when a doctor doesn't accept Medicare assignment and bills you more than Medicare's approved amount. Medicare allows doctors to charge up to 15% above the approved rate. Plan G covers that extra 15%. Plan N doesn't.
Here's the reality: fewer than 5% of doctors nationwide charge excess fees, and many states prohibit them entirely. If you live in Connecticut, Massachusetts, Minnesota, New York, Ohio, Pennsylvania, Rhode Island, or Vermont, excess charges are banned by state law. You can't be billed for them even if you have Plan N.
In states where excess charges are legal, you can avoid them completely by choosing doctors who accept Medicare assignment. Medicare.gov lets you filter search results to show only providers who accept assignment, which eliminates the risk entirely.
Most people worry about excess charges because the Medigap brochures highlight them in bold text. In practice, they almost never come up. I wouldn't choose Plan G over Plan N based solely on this benefit.
When Plan G Makes More Sense
Plan G is the better financial choice if you expect high medical use and want to eliminate as many variables as possible from your out-of-pocket costs. If you're seeing specialists regularly, getting ongoing treatment for a chronic condition, or managing something like cancer or heart disease, the predictability of Plan G is worth paying for.
Plan G also makes sense if the premium gap in your area is unusually small. Some insurance companies price Plan N only $10 to $15 cheaper per month than Plan G. At that margin, the copay-free coverage of Plan G is the smarter pick even if you only see the doctor a handful of times per year.
Finally, if you value simplicity and don't want to think about copays every time you schedule an appointment, Plan G delivers that. Once you've paid the $257 Part B deductible, you don't pay another dollar for Medicare-covered services for the rest of the year.
When Plan N Makes More Sense
Plan N works best for people who are generally healthy, see the doctor infrequently, and want to keep their fixed monthly costs as low as possible. If your typical year includes a couple of routine checkups and maybe one sick visit, Plan N's lower premium will save you money even after accounting for the copays.
Plan N also makes sense if you're someone who researches doctors carefully and doesn't mind confirming that a provider accepts Medicare assignment before booking an appointment. That one step eliminates the excess charge risk entirely, which removes the main coverage gap between Plan N and Plan G.
One other scenario: if you're still working part-time and have creditable employer coverage that coordinates with Medicare, you may not use your Medigap plan very often during those years. In that case, Plan N's lower premium saves you money while you're not leaning on the coverage heavily, and you can always switch to Plan G later if your health changes (though you may have to answer medical underwriting questions depending on your state).
What You Can't Do After Your Initial Enrollment Period
During your Medigap Open Enrollment Period the six months that starts the month you turn 65 and enroll in Medicare Part B insurance companies can't deny you coverage or charge you more based on your health. You have guaranteed issue rights. You can pick Plan G, Plan N, or any other Medigap plan, and the company has to sell it to you at their standard rate.
After that six-month window closes, those protections mostly disappear. If you want to switch from Plan N to Plan G a year later, the insurance company can require you to answer health questions, order medical records, and either decline your application or charge you a higher premium based on your current health. Some states have additional protections (California and Oregon, for example, give you a birthday rule that allows one free switch per year), but most states do not.
This is why your first Medigap decision matters. It's not locked in forever, but changing plans later is harder and often more expensive than getting it right the first time.
How to Compare Actual Premiums in Your Area
Medigap premiums vary significantly by location, age, and insurance company. Two people who are the same age and live 20 miles apart can see premium differences of $40 or $50 per month for the same plan letter, simply because different companies dominate different regions.
The best way to compare real premiums is to use Medicare.gov's plan finder tool. Enter your zip code, your age, and whether you use tobacco, and it will show you every Plan G and Plan N option available in your area along with the monthly cost. You can sort by price and filter by company.
You can also work with an independent insurance broker who sells Medigap policies from multiple companies. They can run the same comparisons and often catch rate details that aren't obvious in the online tool. Just make sure the broker represents more than one carrier if they only sell one company's plans, you're not getting a real comparison.
One thing to watch for: some companies use community-rated premiums (everyone pays the same regardless of age), some use issue-age-rated premiums (your rate is based on your age when you first buy the plan and doesn't increase as you get older), and some use attained-age-rated premiums (your rate goes up every year as you age). Attained-age plans often look cheapest when you're 65, but they can become significantly more expensive by the time you're 75. Ask how the company sets rates before you sign up.
One More Option Worth Considering
If you're comfortable with network restrictions and want to lower your costs even further, Medicare Advantage might be worth comparing alongside Medigap. Medicare Advantage plans replace Original Medicare instead of supplementing it, and many have $0 premiums with modest copays built in. The tradeoff is that you're locked into a network of doctors and hospitals, and you'll need referrals to see specialists in most cases.
That's a bigger tradeoff than it sounds like for some people. But if you live in an area with strong Medicare Advantage options and you don't mind staying in-network, it's worth running the numbers. Use the same plan finder tool on Medicare.gov to see what's available and compare total estimated costs for the year based on your expected medical use.
This isn't a Medigap-versus-Advantage article, so I won't go deeper here. Just know that the choice isn't only between Plan G and Plan N. There's a third path, and for some people, it's the one that makes the most sense.
Making the Decision
Here's how to think through this. Start with the premium difference in your area. If Plan N is $30 cheaper per month and you see the doctor four times a year, you'll save roughly $280 after copays. If Plan N is only $15 cheaper per month and you see the doctor six times a year, Plan G saves you money.
Run the math based on your actual doctor visit history from the past year or two. Don't guess. Pull up your Medicare Summary Notice or your old insurance EOBs and count how many office visits you had. Add in any ER trips that didn't result in admission. Multiply by the copay amounts under Plan N, then subtract that total from the annual premium savings. Whichever number is bigger tells you which plan costs less.
If the difference is close within $50 or $100 per year either way. I'd lean toward Plan G. The peace of mind of not thinking about copays is worth something, and medical use tends to increase as you get older. Locking in the more comprehensive plan now while you have guaranteed issue rights gives you one less thing to reconsider later.
If Plan N saves you $200 or more per year based on your expected use, take it. You can always revisit the decision during your annual Medigap shopping window, and in some states, you'll have options to switch without underwriting if your health stays stable.
Frequently Asked Questions
Q: Can I switch from Plan N to Plan G later if my health changes?
A: You can apply to switch at any time, but after your initial six-month Medigap Open Enrollment Period ends, insurance companies can require medical underwriting. That means they'll ask health questions and may deny your application or charge you a higher premium based on your current health. Some states (like California, Oregon, and Missouri) have rules that give you limited guaranteed issue rights to switch plans, but most states don't. If you think you'll want Plan G eventually, it's often easier to start with it.
Q: Does Plan N's $20 copay apply to every medical appointment?
A: No. The $20 copay only applies to doctor office visits typically your primary care doctor or a specialist consultation. It does not apply to outpatient services like lab work, X-rays, physical therapy, or outpatient surgery. Those services are covered the same way under Plan N as they are under Plan G, with no copay once you've met the Part B deductible.
Q: What happens if I go to the emergency room under Plan N but don't get admitted?
A: You pay up to $50 for that ER visit. If the ER doctor decides to admit you to the hospital, the $50 copay is waived. This is the one copay under Plan N that can add up if you have multiple ER visits in a year, so factor that into your decision if you have a condition that occasionally sends you to the emergency room.
Q: Are Part B excess charges really something I need to worry about?
A: For most people, no. Fewer than 5% of doctors nationwide charge excess fees, and eight states ban them entirely. You can also avoid excess charges by choosing doctors who accept Medicare assignment, which you can verify on Medicare.gov before booking an appointment. I wouldn't choose Plan G over Plan N based solely on excess charge coverage unless you're already seeing a specialist who you know charges above Medicare rates and you're not willing to switch providers.
Q: How much does Plan G cost compared to Plan N in 2026?
A: It depends on your age, location, and which insurance company you're comparing. In most areas, Plan N premiums run $20 to $50 per month lower than Plan G. That gap can be smaller in some regions and larger in others. The only way to know for sure is to check actual quotes in your zip code using Medicare.gov's plan finder tool or by working with an independent broker who can compare multiple companies at once.
