Plan G vs Plan N: The Definitive Comparison

Plan G and Plan N are the two plans almost every new Medicare beneficiary ends up choosing between. They cover identical catastrophic exposure — after that, the difference is pure arithmetic between G’s zero-copay simplicity and N’s 15–30% cheaper premium with modest cost-sharing.

Dimension Plan G Plan N
Part B deductible ($257 in 2025) You pay it, then 100% covered You pay it, then 100% covered
Doctor office copays None $20 per visit
Emergency room copay None $50 (waived if admitted)
Part B excess charges Fully covered You pay them (rare outside a few states)
Typical premium gap Baseline 15–30% cheaper than G
Rate stability Slightly higher increases Historically smaller increases

The math that decides it

A Plan N holder who sees a primary doctor 4 times a year and never visits the ER pays roughly $80–100 in copays annually — far less than the $300–600 yearly premium gap against G in most ZIPs. N flips to the loser when excess charges apply: a provider billing 15% over Medicare-allowed on a $2,000 procedure leaves you a $300 bill that G would have absorbed. Check your doctors for excess-charge billing before choosing N.

Who each plan actually fits

Choose G if you want zero billing surprises, have a chronic condition driving frequent visits, or live where providers routinely take excess charges. Choose N if you are moderately healthy, your doctors accept Medicare assignment without excess charges, and you would rather bank the premium difference. Neither choice is locked in forever — but switching later requires underwriting in most states, so the premium math should include a realistic estimate of your year-five usage, not just year one.

FAQ

Can I switch from Plan N to Plan G later?

Yes, but in most states you must pass medical underwriting. Only California (birthday rule), New York and a few other guaranteed-issue states make the switch routine.

Why is Plan N cheaper if it covers almost the same?

The copays and excess-charge exposure measurably reduce claims paid to carriers, and they also deter members who use care heavily — so carriers price N more aggressively.

Does Plan N cover the Part B deductible?

No. Like every plan sold today except legacy F, you pay the $257 (2025) Part B deductible yourself.
