The Short Answer: Most Good Medigap Plans Cover Your Doctor Copays Completely

If you’re on Original Medicare and you have a solid Medigap plan like Plan G or Plan N, you’re probably not paying a copayment every time you walk into a doctor’s office. But the details matter here, and the differences between plans can cost you real money over time, especially if you see doctors regularly.

Here’s how this actually works. Original Medicare Part B covers outpatient services, including doctor visits. Medicare pays 80% of the approved amount after you’ve met your Part B deductible. That leaves you responsible for the remaining 20% with no cap. That 20% is what people sometimes call a “copayment,” though technically Medicare calls it coinsurance. It’s the same problem either way: you’re on the hook for it.

Medigap steps in to cover that leftover 20%, depending on which plan you buy. Some plans cover it entirely. Some don’t. And one plan has you paying a small flat copay per visit instead. Knowing which is which before you buy a policy is the whole game.

How the Major Medigap Plans Handle Doctor Visit Costs

Not all Medigap plans are equal when it comes to doctor visit costs. The standardized plans are labeled A through N, and they each cover a different combination of Medicare’s out-of-pocket costs. Here’s how the most popular ones shake out specifically for doctor visits:

Medigap Plan	Part B Deductible Covered?	Part B Coinsurance (20%) Covered?	Doctor Visit Cost to You
Plan G	No	Yes, 100%	$0 after $257 deductible (2026)
Plan N	No	Yes, with copays	Up to $20 copay per visit + $257 deductible (2026)
Plan F	Yes	Yes, 100%	$0 (new enrollees ineligible after 2020)
Plan A	No	Yes, 100%	$0 after $257 deductible (2026)
Plan K	No	50%	10% of approved amount after deductible
Plan L	No	75%	5% of approved amount after deductible

Plan G is the most popular plan for new Medicare enrollees right now, and for good reason. Once you’ve paid the 2026 Part B deductible of $257 for the year, your Medigap Plan G covers 100% of that 20% coinsurance on every doctor visit for the rest of the year. You show up, you see the doctor, you walk out without a bill. That’s not a small thing if you’re managing a chronic condition or you’re just someone who sees specialists regularly.

Plan N is worth understanding too, because it’s cheaper in premiums and still covers that 20% coinsurance, but it adds a copay structure on top. You can pay up to $20 for office visits and up to $50 for emergency room visits that don’t lead to inpatient admission. For some people that’s a fine trade. For others it’s annoying and potentially adds up.

The Part B Deductible Situation (This Is Where People Get Confused)

I’ve seen a lot of people assume that their Medigap plan kicks in from dollar one at the doctor’s office. That’s not always true, and it’s one of the most common points of confusion I run into.

For Plan G and Plan N, your Medigap plan does not cover the Part B deductible. In 2026, that deductible is $257 per year. So your first $257 worth of covered outpatient services each calendar year comes out of your pocket. After that, your Medigap plan takes over the 20% coinsurance.

Here’s why that rule exists. When Congress eliminated Plan F for new Medicare enrollees in 2020, they did it specifically to keep beneficiaries with some “skin in the game” on Part B costs. The theory was that if Medicare pays everything from the first dollar, people use more services than they otherwise would. Whether you agree with that reasoning or not, the result is that Plan G and Plan N enrollees pay that $257 deductible themselves.

For most people, $257 is not a budget-breaker. You hit it with your first or second doctor visit of the year and you’re done worrying about it. But it’s worth knowing so you’re not caught off guard when you get a bill in January after your first appointment of the new year.

The Common Mistake: Thinking Medigap Works Like Regular Insurance Copays

Here’s something I see constantly, especially with people who are just aging into Medicare at 65. They expect Medigap to work the way their old employer coverage worked, where every doctor visit costs a flat $30 or $40 and that’s it. Medigap doesn’t work that way, and if you go in expecting it to, you’ll be confused about your bills.

Medigap covers Medicare’s cost-sharing, not a separate set of copays it invented itself. So what you’re actually getting with Plan G is: Medicare pays 80% of the approved amount, and your Medigap plan pays the remaining 20%. The end result looks the same as a $0 copay, but the structure is different. It’s a percentage-based system layered over Medicare, not a flat copay system standing on its own.

This matters because the dollar amounts are tied to what Medicare approves. If you see a doctor who accepts Medicare assignment, which means they agree to Medicare’s approved rates, you’re protected and your out-of-pocket is predictable. If you see a doctor who doesn’t accept Medicare assignment, you could face “excess charges,” which are fees above what Medicare approves. Plan G covers those excess charges. Plan N does not. That’s a real difference if you’re seeing specialists in areas with a lot of non-participating providers.

I’ve talked to people in California and New York who got hit with excess charges under Plan N and had no idea that was possible. If you’re in a state where excess charges are more common, Plan G’s excess charge coverage is worth paying for.

Plan G vs. Plan N: Which One Should You Actually Choose?

This is the real question for most people shopping Medigap right now, and I’m going to give you my actual opinion rather than a wishy-washy “it depends.”

For most people at 65, Plan G is the better starting point. Here’s the math. Plan G premiums for a 65-year-old typically run $100 to $200 per month depending on your state and insurer. Plan N usually runs $20 to $40 less per month. That’s roughly $240 to $480 in annual premium savings with Plan N.

But with Plan N, you’re paying up to $20 per doctor visit. If you see your primary care doctor four times a year and two specialists twice each, that’s eight visits, which is $160 in Plan N copays. Add the excess charge exposure and the savings start to shrink fast. For someone with three or four visits a year who is generally healthy and sees only Medicare-participating providers, Plan N can absolutely make sense.

For a 67-year-old in Ohio managing diabetes, seeing an endocrinologist quarterly and a primary care doctor every few months? Plan G. The predictability alone is worth the extra premium. You’re not thinking about whether this visit triggers a copay. You just go.

The one group I’d genuinely push toward Plan N: healthy 65-year-olds who are budget-conscious, live in states that ban excess charges (like Connecticut, Massachusetts, Minnesota, New York, Ohio, Pennsylvania, and Vermont), and are comfortable with a small copay per visit. For them, Plan N makes a lot of financial sense.

Bottom Line

For most people, Plan G is the right Medigap plan if you want doctor visit costs genuinely handled. You pay the 2026 Part B deductible of $257 once per year, and after that, your doctor visits cost you nothing out of pocket, no copays, no coinsurance, no surprises. Plan N is a reasonable runner-up if you’re healthy, see doctors infrequently, and live in a state without excess charge risk. Don’t let premium sticker shock push you into a plan that leaves you paying at every visit, especially if you’re someone who actually uses medical care.

Frequently Asked Questions

Does Medigap cover specialist visit copays?

Yes, the same rules apply to specialist visits as to primary care under Medicare. Plan B covers 80% of the approved amount for both, and your Medigap plan covers the remaining 20% coinsurance. With Plan G, you pay nothing out of pocket for specialist visits after you’ve met the annual Part B deductible.

What if my doctor doesn’t accept Medicare?

If your doctor has opted out of Medicare entirely, Medicare won’t pay anything for the visit, and neither will your Medigap plan. Medigap only covers Medicare’s cost-sharing. It can’t pay for services Medicare itself doesn’t cover. This is rare but worth confirming before you see a new provider.

Are there any Medigap plans that cover the Part B deductible?

Plan F covered it completely, but anyone who became eligible for Medicare on or after January 1, 2020 cannot enroll in Plan F. If you were already on Medicare before 2020, you might still be on Plan F, and if it’s affordable and you’re happy with it, there’s no reason to switch. For everyone else, Plan G is the closest equivalent, minus the deductible coverage.

Will my Medigap plan cover urgent care visits?

It depends on whether the urgent care center accepts Medicare. If it does, Medicare Part B covers the visit as an outpatient service, and your Medigap plan covers the 20% coinsurance just like a regular doctor visit. Plan N applies a copay of up to $20 for these visits as well. Always confirm that urgent care centers in your area participate in Medicare before assuming you’re covered.
