Medicare Plan G vs. Plan N: When the Cheaper Plan Is Actually the Smarter Choice

Your parent has decided on Medigap over Medicare Advantage. Good — that's the hard decision done. Now comes the second decision that trips up almost everyone: Plan G or Plan N?

The insurance agent will probably recommend Plan G. It's the most popular Medigap plan in the country, and for good reason — it covers nearly everything. But Plan N is typically $30–$50 cheaper per month, and the coverage differences are smaller than most people realize. The question isn't "which plan is better?" — it's "which plan is better for your parent's specific situation?"

This article walks you through the math.

What Plan G and Plan N actually cover

Both Plan G and Plan N are standardized by the federal government, which means the benefits are identical regardless of which insurance company sells the policy. A Blue Cross Plan G in Texas covers the same things as an Aetna Plan G in Ohio. The only differences between carriers are price, customer service, and rate increase history.

Here's what they share:

• Part A hospital coinsurance and hospital costs up to 365 additional days after Medicare benefits are used up
• Part B coinsurance or copayment (with some exceptions for Plan N)
• Blood (first 3 pints)
• Part A hospice care coinsurance or copayment
• Skilled nursing facility care coinsurance
• Part A deductible
• Foreign travel emergency (80%, up to plan limits)

And here's where they differ:

That's it. Those three items — excess charges, office visit copays, and ER copays — are the entire difference between Plan G and Plan N.

The breakeven calculation

This is where most articles fail you. They list the differences but don't do the math. Let's fix that.

The premium difference: Plan N is typically $30–$50 cheaper per month than Plan G from the same carrier in the same zip code. That's $360–$600 per year in savings.

The copay cost: Plan N charges up to $20 per doctor visit and up to $50 per ER visit (if not admitted to the hospital). The key word is "up to" — many providers don't charge the full copay.

The breakeven math:

If Plan N saves your parent $40/month ($480/year) in premiums, and each doctor visit costs $20 in copays, your parent would need to visit the doctor 24 times per year before Plan N stops saving money. That's roughly once every two weeks.

Most seniors see their primary care doctor 4–6 times per year and specialists another 4–8 times. A typical year might be 8–14 visits total. At $20 per visit, that's $160–$280 in copays — still well below the $480 saved in premiums.

The simple rule: If your parent sees a doctor fewer than 20–24 times per year, Plan N almost always comes out ahead financially.

The excess charges question

This is the one coverage gap that makes people nervous about Plan N. Here's the reality:

What are excess charges? When a doctor doesn't accept Medicare "assignment" (the Medicare-approved payment amount), they can charge up to 15% more than the Medicare rate. This extra amount is called an "excess charge."

Plan G covers excess charges. Plan N does not.

How worried should you be? Not very. According to CMS data, fewer than 5% of U.S. doctors charge excess fees. The number is even lower in many states — Connecticut, Massachusetts, Minnesota, New York, Ohio, Pennsylvania, Rhode Island, and Vermont have laws prohibiting Medicare excess charges entirely. If your parent lives in one of these states, this difference between Plan G and Plan N is meaningless.

Even in states that allow excess charges, the financial exposure is limited. The maximum excess charge is 15% above the Medicare rate. For a $200 office visit, that's $30 extra. For most seniors, the cumulative excess charges in a year would amount to far less than the premium savings from choosing Plan N.

The one exception: If your parent sees a specialist who is known to charge excess fees — some surgeons and anesthesiologists do — and they're facing a major procedure, excess charges could add up. But this is a scenario you can check in advance: call the doctor's billing department and ask if they accept Medicare assignment.

Who should choose Plan G

Plan G is the right choice for your parent if:

• They want zero financial surprises. Plan G covers everything except the Part B deductible ($257/year). Once that's paid, there are no copays, no coinsurance, and no excess charges. The total annual cost is completely predictable.
• They see doctors who charge excess fees. If your parent's primary care doctor or key specialists don't accept assignment, Plan G eliminates this variable.
• They have anxiety about medical bills. Some families value the peace of mind more than the $400–$600 annual savings. That's a legitimate choice. The emotional cost of worrying about copays may exceed the financial cost of paying them.
• They visit the doctor very frequently. If your parent has multiple chronic conditions requiring 20+ doctor visits per year, the copays in Plan N start to eat into the premium savings.

Who should choose Plan N

Plan N is the right choice for your parent if:

• They're relatively healthy and see the doctor fewer than 15–20 times per year. The premium savings will exceed the copay costs by hundreds of dollars annually.
• They live in a state that prohibits excess charges. In these states, the excess charge gap between Plan G and Plan N is irrelevant — the coverage is functionally identical except for the small copays.
• They're cost-conscious and comfortable with small, predictable copays. A $20 copay per visit is not the same as unpredictable medical bills. Plan N's costs are capped and known in advance.
• They want to save money on premiums that compound over time. A $40/month difference today grows as premiums increase — Medigap premiums typically rise 5–8% annually, and Plan G's higher base means its dollar increases are proportionally larger.

What about Plan F?

You might hear about Plan F, which was historically the most comprehensive Medigap plan. Plan F covered everything Plan G covers plus the Part B deductible.

Plan F is no longer available to anyone who turned 65 after January 1, 2020. If your parent is newly enrolling, they cannot buy Plan F.

Even for those grandfathered in, Plan F is usually a bad deal. The only additional benefit over Plan G is coverage of the $257 annual Part B deductible — but Plan F premiums are typically $300–$500 more per year than Plan G. You're paying an extra $300–$500 to avoid a $257 deductible. The math doesn't work.

Worse, since no new enrollees can join Plan F, the risk pool is aging and shrinking. This means Plan F premiums will continue rising faster than Plan G premiums — a phenomenon actuaries call a "death spiral." If your parent is currently on Plan F, it may be worth switching to Plan G during the next enrollment period.

How to decide: the 3-minute test

1. How often does your parent visit the doctor? Count all visits — primary care, specialists, labs, physical therapy. If it's fewer than 20 visits per year, Plan N likely saves money.
2. Does your parent live in a state that bans excess charges? If yes, the excess charge difference is moot. Choose Plan N.
3. Do your parent's doctors accept Medicare assignment? Call and ask. If they do, excess charges aren't a factor.
4. What's the premium difference in your parent's zip code? Get quotes for both Plan G and Plan N from the same carrier. The national average difference is $30–$50/month, but it varies by location.

If the answers point to Plan N, you'll likely save your parent $400–$600 per year with minimal additional risk. If the answers are uncertain, Plan G buys peace of mind for a relatively modest premium.
