Medigap Plan G vs Plan N: How to Choose

The short answer: Plan G and Plan N cover almost the same things. The differences come down to three: Plan N charges small copays for office and emergency visits, Plan N does not cover Part B excess charges, and Plan N usually costs noticeably less each month. Plan G buys maximum predictability; Plan N trades a little cost-sharing for a lower premium. Which trade wins depends mostly on how often you see doctors.

These two letters are where most Medigap shoppers land, and the choice between them generates more back-and-forth than any other decision at 65. The good news: because Medigap plans are standardized by law, this comparison is stable. A Plan G is a Plan G everywhere. Here is the whole difference, honestly laid out.

What do Plan G and Plan N both cover?

Everything that matters most, identically:

• The 20% of doctor and outpatient costs that Original Medicare leaves uncovered — the piece with no annual cap on its own
• The hospital (Part A) deductible, which applies per benefit period and catches people off guard
• Hospital coinsurance and an additional year of hospital days after Medicare’s coverage ends
• Skilled nursing facility coinsurance
• Part A hospice cost-sharing
• Emergency care during foreign travel, up to the plan’s limits

Neither plan covers the annual Part B deductible — $283 in 2026 — which you pay out of pocket once per year under either plan before the coverage above takes over. (Only Plan F covered that deductible, and it closed to people newly eligible after January 1, 2020.)

Difference one: Plan N’s copays

With Plan N, after the Part B deductible you pay up to $20 for office visits and up to $50 for emergency room visits that do not end in admission. That is the whole copay story — no copays for surgery, imaging, lab work, hospital stays, or anything else.

The math is straightforward. Someone who sees doctors a handful of times a year gives back a small fraction of what the lower premium saves. Someone managing several conditions with monthly appointments gives back more of it. Count your typical year of visits, multiply, and compare that number against the premium gap — the arithmetic usually makes the decision clearer than any sales pitch.

Difference two: Part B excess charges

Medicare sets an approved amount for every service. A small minority of providers do not accept that amount as full payment — they are allowed to charge up to 15% more, and that surcharge is called an excess charge. Plan G pays excess charges; Plan N does not.

Context matters here, in both directions. The overwhelming majority of doctors accept Medicare’s approved amount in full, so many Plan N holders never see an excess charge in their lives — and you can ask any provider whether they “accept assignment” before care. On the other hand, Georgia does not prohibit excess charges (a handful of states do), so the possibility is real here rather than theoretical, and it is most likely to surface at exactly the wrong moment — a specialist you very much want to see. Small risk, honestly disclosed: that is the shape of it.

Difference three: the premium

Plan N’s premium runs noticeably below Plan G’s for the same person in the same ZIP code — that is the entire reason the copay trade exists. The gap varies by company and age, which is why the useful comparison is never “G vs N” in the abstract but this company’s G vs that company’s N, priced for you. Because the benefits are standardized, an independent agent can line those numbers up in minutes, and the premium is the same whether an agent helps or not.

Worth knowing: a high-deductible version of Plan G also exists — much lower premium, with the full coverage starting after a larger annual deductible. For someone comfortable self-insuring the front end of a bad year, it is a legitimate third option to price.

So which one fits you?

Plan G tends to fit people who want the bill to be a non-event — frequent specialist visits, ongoing conditions, or simply a temperament that would rather pay a known premium than meet any surprise, however small.

Plan N tends to fit people with few appointments in a typical year, comfort asking providers whether they accept assignment, and a preference for keeping monthly costs down while staying fully protected against the catastrophic side.

Neither answer is wrong. The wrong answer is choosing by slogan — “most popular” or “cheapest” — rather than by your own arithmetic and temperament. And remember the timing: during your six-month Medigap open enrollment window, both doors are open without health questions. Later, switching between them can require underwriting.

Common questions about Plan G and Plan N

Is Plan G worth the higher premium over Plan N?

It depends on your year. Multiply your typical number of office visits by the copay, add a cushion for the excess-charge possibility, and compare that to twelve months of premium difference. Frequent-visit years favor G; light-visit years favor N. Temperament counts too — some people happily pay more monthly to never think about a medical bill again, and that is a valid reason.

Can I switch from Plan N to Plan G later?

You can apply at any time — but outside your original six-month window, the application generally goes through medical underwriting in Georgia, meaning health questions and the possibility of a higher price or a decline. The practical takeaway: choose deliberately the first time, because the switch later is not guaranteed.

Do Plan G and Plan N use different doctor networks?

Neither uses a network at all. Both work with any provider in the country who accepts Medicare — the plans differ only in the cost-sharing described above, never in which doctors you can see. That freedom is a feature of every Medigap plan paired with Original Medicare.

Does Plan G or Plan N include drug coverage?

Neither does. Both pair with a standalone Part D prescription plan, chosen separately based on your medication list and pharmacy. The parts of Medicare guide shows how the pieces fit together.

The simple version

Same coverage skeleton, three differences: copays, excess charges, premium. Do the arithmetic on your own visit count, decide what surprises are worth to you, and price both letters across several companies before deciding — or have someone independent do the lining-up for you. If you are weighing supplements against the other path entirely, read Medigap vs. Medicare Advantage first.
