What is Medicare Supplement Plan N?

Once Medicare pays its approved amount for health care costs and services, Medicare Supplement Plan N pays for certain out-of-pocket costs, such as your Medicare Part A deductible or Part B coinsurance. However, there are copays for certain doctor’s office visits and emergency room visits

Centers for Medicare & Medicaid Services. Learn How Medigap Works. Accessed Feb 15, 2024.

  • Office visits: Up to $20 for some office visits.

  • Emergency room visits: Up to $50 if you're not admitted to hospital inpatient care.

After that, Plan N covers anything of your Part B copay or coinsurance that's left.

Medicare Supplement Insurance Plan N is the third most popular plan type, covering about 10% of all Medigap members as of 2021

. Plan F and Plan G have more members (and of the two, only Plan G is available to new Medicare members).

Medigap plans are only available if you have Original Medicare — they can’t be used with Medicare Advantage plans.

There are 10 standardized Medigap plans available in most states (except Massachusetts, Minnesota and Wisconsin, which use different standards). The plans differ in terms of coverage for services, out-of-pocket limits and premium costs.

Medicare Supplement Plan N pros and cons

Medigap Plan N has pros and cons:

Premiums: Plan N has lower premiums than other popular options like Plan G and Plan F.

Availability: Plan N is available from nearly every Medigap company.


Copays: Unlike most plan types, Plan N has copays for certain medical visits.

How much does Medicare Supplement Insurance Plan N cost?

Buy Medigap Plan N during Medigap open enrollment

The best time to buy a Medicare Supplement Insurance policy is during your Medigap open enrollment period

Centers for Medicare & Medicaid Services. Get Ready to Buy. Accessed Feb 15, 2024.

This period happens only once. It starts once you’re 65 and enrolled in Medicare Part B, and lasts for six months. (If you're still working after 65 and covered by a group employer plan that is deemed creditable coverage, your six-month period starts after you’ve ended active employment or no longer have that insurance.)

Medigap policies are cheapest and easiest to get during this open enrollment period because insurance companies aren’t allowed to factor your health or medical history into your price. After the period ends, the prices may go up or you may be denied coverage due to your health status or medical history.

In some states, insurance companies sell Medigap plans to those under 65 who are living with a disability and are eligible for Medicare. You can find more information through your State Health Insurance Assistance Program, or SHIP.

When shopping for a Medigap plan, review your medical records. If you don’t frequently visit the doctor, then Plan N may be the better option for you.
