Medicare Supplement Insurance Plan F vs. Plan N: How to Choose

There are two major differences between Medigap Plan F and Medigap Plan N:

Plan F covers the Medicare Part B deductible and Medicare Part B excess charges, while Plan N does not.

Also, Plan F is not available to Medicare beneficiaries who became eligible for Medicare on or after January 1, 2020. If you became eligible for Medicare prior to 2020, you may be able to get Plan F if it is available in your area.

Refer to the following chart for a side-by-side view of the benefits that each plan provides. 

Is Plan F the best Medicare Supplement plan?

Medigap Plan F is the most popular Medicare Supplement Insurance plan.¹

Medigap Plan F helps pay for more out-of-pocket Medicare costs than any other type of Medigap plan, but it may also come with a higher premium.

There are 10 standardized Medigap plans available in most states.

Each type of Medigap policy offers the first four basic benefits listed below. Each plan offers a different combination of the other five additional benefits:

1. Part A hospital coinsurance and hospital costs
2. Part A hospice care coinsurance or copayment
3. Part B coinsurance or copayment
4. First 3 pints of blood
5. Part A deductible
6. Part B deductible
7. Part B excess charges
8. Skilled nursing care
9. Foreign travel emergency care costs

Medigap Plan F offers coverage for all nine of the benefits listed above.

High-deductible Plan F

Medigap Plan F also comes with a high-deductible option.

High-deductible Plan F features an annual deductible of $2,800 in 2024. You must meet this deductible before the plan's coverage begins.

One potential benefit of the high deductible is a lower average premium, which is discussed below.

Plan N does not have a high-deductible option.

What is Medicare Supplement Plan N?

Medigap Plan N is the third-most popular Medicare Supplement Insurance plan.¹

Plan N covers seven of the nine basic Medigap benefits, excluding coverage for the Medicare Part B deductible ($257 per year in 2025), and Medicare Part B excess charges.

With Medigap Plan N, you are also responsible for up to a $50 copay for certain emergency room visits that don't result in admission for in-patient care, and up to a $20 copay for some visits to your physician.

Depending on the types of health care costs you anticipate, the money you save on potentially lower Plan N premiums could possibly make it a better choice than Plan F.

The decision will ultimately come down to your specific needs.

What is the average cost of Medigap Plan F vs. Plan N?

The average premium for Medigap Plan F in 2023 was $202 per month.²

The average premium for Medigap Plan N in 2023 was $110 per month.²

The high deductible option for Plan F had an average premium of only $83 per month in 2023.²

How do I choose between Plan F vs. Plan N?

So Plan N average premiums cost less  than standard Plan F average premiums, but Plan F covers more. How do you decide between these two plans?

Let's start by examining one of the benefit areas that Plan F covers but Plan N does not, which is the Part B deductible.

• If you were enrolled in Plan N that charged the average premium ($110 per month) and paid the Part B deductible in full (which was $226 per year in 2023), you would have paid $1,546 on premiums and your deductible.

• If you were enrolled in Plan F that charged the average premium ($202 per month) and didn't have to pay the Part B deductible, you still would have paid $2,650 on premiums alone.

That's a difference of $1,104 more for the year for Plan F.

Medigap Plan F also covers Part B excess charges.

• When you visit a doctor who does not accept Medicare assignment, this means they do not agree to accept Medicare reimbursement as payment in full for the costs of your covered services. 

• If you go to a non-participating doctor, you could have to make a payment of up to 15% of the Medicare-approved amount for a service out of your own pocket. This 15% cost is called the Part B excess charge.

Medigap Plan N does not provide any coverage for Part B excess charges.
