Medigap Plan NotesThe ten standardized Medicare Supplement plans, explained with numbers

Plan G vs Plan N: the break-even maths

How many doctor visits it takes for Plan N's copays to cancel out its lower premium, using example 2026 premiums and the $283 Part B deductible.

Plan G and Plan N are the two most popular Medigap plans for people new to Medicare. Both cover hospital stays, skilled nursing, and the 20% Part B coinsurance on big bills. The difference is in the small stuff, and that makes it a straightforward maths problem.

What each plan leaves you to pay

Plan G Plan N
Part B deductible ($283 in 2026) You pay You pay
Office visit copay $0 Up to $20
ER visit not admitted $0 Up to $50
Part B excess charges Covered Not covered

The break-even

Premiums vary by insurer, age, ZIP code and rating method, so use your own quotes. As an example, suppose Plan G costs $165 a month and Plan N $125.

Annual cost: Plan G vs Plan N by number of office visits (example premiums) $0 $500 $1,000 $1,500 $2,000 $2,500 0 2 6 8 12 14 18 20 Plan G Plan N Office visits with a copay per year Premium + out of pocket
Example premiums only. The lines cross where the copays equal the annual premium difference.

The annual premium gap is $480. At up to $20 per visit, you would need about 24 office visits a year with a copay before Plan N costs more than Plan G. Most healthy 65-year-olds see a doctor three to six times a year, so on these numbers Plan N wins comfortably.

The gap between G and N premiums is often larger at older ages and in some states, which pushes the break-even higher still.

Excess charges: the real Plan N risk

Doctors who accept Medicare but not "assignment" can charge up to 15% more than the Medicare-approved amount. Plan G pays that excess; Plan N does not. On a $3,000 Medicare-approved surgery, the excess could be $450.

In practice excess charges are uncommon: the large majority of doctors accept assignment, and several states ban excess charges entirely. Ask your regular doctors whether they accept assignment before choosing N.

Switching later

Moving from N to G after your Medigap open enrollment period usually requires medical underwriting, unless your state has special rules. Washington, for example, lets people with a Plan B through N switch to another plan in that group. Details are in our Washington switching guide. For help comparing G and N quotes for Washington, Maru Insurance's Medicare Supplement page explains how they compare carriers.

Questions people ask

Is Plan N cheaper than Plan G overall?

For most healthy people, yes: the premium saving usually exceeds the copays. Run your own quotes.

What are Part B excess charges?

Up to 15% above the Medicare-approved amount that non-assigning doctors may bill. Plan G covers them, Plan N does not.

Do both plans cover hospital stays fully?

Yes. Both cover the Part A deductible and hospital coinsurance.

Can I switch from N to G later?

Usually with medical underwriting, unless a state rule or guaranteed issue right applies.
