Medicare Plan N: Coverage, Cost and How It Works
Compare Medicare Plans in Your Area
Medicare Plan N is the best Medigap plan for balancing good coverage with affordable rates.
At $121 per month on average, it's cheaper than Plans F and G but has coverage that's almost as good. It is the third-most-popular Medigap option, making up 10% of all Medicare Supplement plans.
How does Plan N work?
Medicare Supplement plans, including Plan N, let you pay less when you go to the doctor or hospital.
Like other Medicare Supplement plans, also called Medigap plans, Plan N pays for costs that Original Medicare doesn't.
Original Medicare only pays for about 80% of your medical costs. A Medicare Supplement plan can help lower your bills by paying for some of the remaining costs.
You can buy Medigap plans, including Plan N, from health insurance companies like AARP/UnitedHealthcare, Aetna and Cigna. Medigap plans with the same letter all have the same coverage, no matter the company. The best way to choose a company is to compare prices, customer service and added perks.
How supplemental policies work
- Medicare Parts A and B pay their portion of medical expenses, usually 80% of costs.
- Supplemental plans then pay some of the rest, filling in gaps that Medicare doesn't pay.
- You pay the remainder of the bill, if there is any.
What does Medicare Supplement Plan N cover?
Plan N covers the $1,676 Medicare Part A deductible and coinsurance for Medicare Parts A and B.
Category | Plan N coverage |
|---|---|
| Part A coinsurance (hospital care) | |
| Part B coinsurance (medical care) | |
| Blood (first 3 pints) | |
| Part A hospice care coinsurance | |
| Skilled nursing home coinsurance | |
| Part A deductible | |
| Part B deductible | |
| Part B excess charges | |
| Foreign travel emergencies | 80% of costs |
Plan N has some of the best coverage of any Medigap plan. Only Plans C, F and G have more coverage. You can only get Plan C or F if you were eligible for Medicare before 2020.
If you have Medicare Plan N, you have to pay a flat fee when you see a doctor.
Plan N does not cover the extra amount that doctors can charge if they do not accept Medicare-approved rates. These are called Part B excess charges, and they don't happen often because most doctors use the Medicare-approved rates for medical care.
Plan N does not cover your low Medicare Part B deductible. And Plan N copays for doctor visits don't count toward the Part B deductible. Plan N does not have a separate deductible aside from the Part B deductible.
No matter how much medical care you need each year, you'll still have to pay your share of certain medical bills. That's because Plan N does not have an out-of-pocket limit. No matter how high your bills are, you'll still have to pay your portion.

|---|---|
| Alabama | $103 |
| Alaska | $122 |
| Arizona | $114 |
| Arkansas | $132 |
| California | $146 |

Medicare Plan N vs. Plan G
You should get Plan N if you want low monthly costs but also coverage that is almost as good as Plan G.
If you're willing to pay more each month, Plan G has slightly better coverage.
Plan differences | Plan G | Plan N |
|---|---|---|
| Average cost | $159/month | $121/month |
| Medicare Part B coinsurance for medical care | ||
| Medicare Part B excess charges |
Plan N is a better choice if budget is your main concern, or if you don't need as much medical care. But Plan G could be a better choice if you think you will go to the doctor often.
Let's say, for example, that Plan N costs $150 per month, while Plan G costs $200 a month.
If you have Plan N and visit the doctor twice a month, you'll pay up to an extra $40 in copays. In this case, the cost of Plan N plus the copays would be $2 more that month than the total cost for Plan G, which does not charge copays. Even though the monthly rate is more expensive, Plan G is a better option if you go to the doctor often.
It is difficult, if not impossible, to predict how many times you are going to have to visit a physician or an ER in the course of a year, but you might have a general idea. When comparing Plans N and G, think about how often you usually see a doctor. This can help you decide if Plan N is actually cheaper with the copays factored in.
High-deductible Plan G is a low-cost alternative
High-deductible Plan G can give you peace of mind that you won't have high medical bills if you suffer a bad illness or injury. It's cheaper than Plan N but has more coverage after pay the first $2,870 of your medical bills, called the deductible. The amount you pay toward the plan's deductible counts toward your $257 Part B deductible.
A high-deductible Plan G costs an average of $49 per month.
Is Plan N or Plan G more popular?
Medigap Plan G is more popular than Plan N.
More than a third of people who buy Medigap plans choose Plan G or the high-deductible version. About 10% of people choose Plan N.
Plan F, including the high-deductible version, is popular. It makes up almost 1 in 4 Medigap plans. You can only buy Plan F if you were eligible for Medicare before 2020.
Plan G is more popular than Plan N because it has more coverage and doesn't charge doctor and emergency room copays.
Is Plan N the best Supplement plan for you?
Medigap Plan N is good if you're on a budget and still want good coverage.
Plan N is cheaper than Plan F or Plan G, and you'll have some out-of-pocket costs for medical care. However, your medical costs will be minimal, and you won't pay anything for expensive medical care such as hospital stays.
There are multiple factors to consider when choosing the best plan for you.
- Coverage vs. cost: Think about how much you can afford to pay each month and how much coverage you need for your medical care.
- Pricing differences between providers: The cost for Medicare Supplement plans changes between insurance companies. Comparing companies lets you get the same coverage for the best price.
- Out-of-pocket costs: Some Medigap plans have deductibles. And not every plan covers Medicare Parts A and B coinsurance. This means that you'll have to pay more for your medical care with some plans than with others.
- Extra perks: Some companies give you extra benefits like free gym memberships or coverage for vision and dental care. You shouldn't choose a plan just for the perks. But you might be able to narrow down your choices based on what extra benefits a plan has.

Frequently asked questions
What is Medicare Plan N?
Plan N gives you extra coverage that helps pay for the things that Original Medicare doesn't. For example, Plan N pays for your $1,676 yearly Part A deductible, as well as your share of the medical bills you get when you go to a doctor or stay in the hospital. Plan N has more coverage than Plan K, which is also a cheap option, but less coverage than Plan G, which is more popular.

With Plan N, you still have to pay up to $20 when you visit a doctor and up to $50 if you go to the emergency room. And Plan N doesn't pay for the Part B deductible. Only Plans C and F do that, but you can't get those plans unless you could get Medicare before 2020.

Plan G is more expensive than Plan N, but it also has better coverage. With Plan G, you don't have to pay when you see a doctor or visit an emergency room, but you do with Plan N.
