Plan G vs Plan N in California
Medicare Supplement Plan G vs Plan N in California
Plan G vs Plan N is the decision most new Medigap buyers in California actually face. Both are Medicare Supplement plans that cover the hospital deductible and nearly all of the 20 percent coinsurance. They differ in three places only: Plan G covers Part B excess charges and has no visit copays; Plan N charges small copays, leaves excess charges with you, and costs less each month.
Because both letters are standardized, the plan g vs plan n choice is not about which carrier has better coverage. It is a break-even question: will your Plan N copays for the year cost less than the premium you save by not buying Plan G? This page runs that math with real California prices.
The real differences, side by side
Everything not listed here is the same on both plans, including the Part A deductible, skilled nursing coverage, hospice, and the freedom to use any provider who accepts Original Medicare patients.
| Plan G | Plan N | |
|---|---|---|
| Monthly premium | Higher | Lower, for the same person at the same carrier |
| Part B deductible ($283 in 2026) | You pay it | You pay it |
| Office visit copays | None after the Part B deductible | Up to $20 per visit |
| Emergency room copays | None after the Part B deductible | Up to $50, waived if you are admitted |
| Part B excess charges | Covered | Not covered. You pay them |
| Part A deductible | Covered | Covered |
The California break-even, with real prices
Use the statewide snapshot on this site. Across 8 California ZIPs checked in the California Department of Insurance 2026 Medicare Supplement Rate Guide, at age 65, for an individual, non-tobacco policy, the lowest Plan G premium listed is $1,946 per year and the lowest Plan N premium listed is $1,369 per year. That is a $577 yearly gap between the two lowest prices at the same age and profile. These are guide survey rates across companies, not quotes, and the gap for your own age and ZIP will differ.
Now price the copays. At up to $20 an office visit, $577 buys about 29 office visits before Plan N copays catch up with that premium gap, and that is before any emergency room copays or excess charges. If you see doctors a few times a year, Plan N keeps most of that $577. If you see specialists every month, the copays can eat the gap, and Plan G is the calmer plan to own.
Two cautions on the example. First, compare premiums from the same carrier when you can, because the lowest G and the lowest N in a guide table usually come from different companies. Second, excess charges do not fit this arithmetic: one doctor who bills excess charges can cost more than a year of copays. Checking whether your doctors accept Medicare assignment comes before the math.
A simple rule for choosing
- Choose Plan G if you see doctors often, are managing ongoing conditions, want the most predictable year, or have a doctor who does not accept Medicare assignment.
- Choose Plan N if you see doctors a handful of times a year, your doctors accept assignment, and you would rather keep the premium difference and pay small copays as you go.
- Price both letters at your own age and ZIP before deciding. The premium gap between G and N varies by carrier, and sometimes it is small enough that Plan G is the obvious buy.

Questions and answers
What is the main difference between Plan G and Plan N?
Three things: Plan G covers Part B excess charges and Plan N does not; Plan N has copays of up to $20 for office visits and up to $50 for emergency room visits that do not lead to admission, and Plan G has neither; and Plan N premiums are lower. Everything else, including the Part A deductible and the Part B deductible you pay yourself ($283 in 2026), is the same.
Which is better in California, Plan G or Plan N?
Neither, for everyone. Plan G is better for frequent care and full predictability. Plan N is better for people with a few visits a year whose doctors accept Medicare assignment, when the premium savings beat the copays. The break-even section on this page shows how to run the comparison with California prices.
Can I change between Plan G and Plan N later?
From G down to N, yes, easily in California: that is a switch to lesser benefits, which the California Birthday Rule protects for 60 days starting on your birthday each year, with no health questions. From N up to G is a move to richer benefits and is not protected by the Birthday Rule, so it usually requires medical underwriting outside your first six months on Part B or a guaranteed issue window.
