• Plan N is a Medicare supplement (Medigap) plan that helps cover the costs of medical care.
  • Federal law ensures that no matter where you purchase your Medigap Plan N, it will include the same coverage.
  • The cost for Medigap Plan N may vary based on where you live, when you enroll, and your health.
  • Enrolling in Medigap when you’re first eligible, around your 65th birthday, is the easiest way to get the lowest cost.

Medicare Supplement Plan N, also called Medigap Plan N, is a type of supplemental insurance to help cover some of the out-of-pocket costs from Medicare. While the plan has standardized coverage, the costs vary by the insurance company and geographic area where you live.

Medicare supplement “plans” are different from Medicare “parts.” Plans are a part of Medicare supplement insurance, while Medicare “parts” describe different aspects of care, such as hospital care with Medicare Part A or medical care with Medicare Part B.

In this article, we’ll discuss the costs you can expect if you choose Medigap Plan N.

Private health insurance companies sell Medigap Plan N. The cost and availability of these plans vary based on your geographic location.

The following are some examples of cost ranges for Medigap Plan N monthly premiums in different cities across the United States in 2021:

LocationPlan N monthly premium
Birmingham, AL $93–$288
Charlotte, NC$81–$270
Indianapolis, IN$79–$353
New York, NY$190-–309
Phoenix, AZ$93–$338
San Diego, CA$93–$228
Seattle, WA$124–$205

As you can see, the costs vary quite a bit based on where you live. The prices shown above are also based on a 65-year-old man who doesn’t use tobacco. To find prices specific to your situation, enter your ZIP code in Medicare’s Medigap plan finder tool.

It’s also important to note that there’s no set out-of-pocket limit with this plan.

The Centers for Medicare & Medicaid Services (CMS) mandate that Medigap plans are standardized. This means no matter who sells the plan, the basic benefits are the same.

Plan N coverage includes:

  • Part A coinsurance and hospital costs for up to an additional 365 days after you use your Medicare benefits
  • Part B coinsurance or copayments, with some exceptions: Plan N may require you to pay $20 for some doctor’s office visits and $50 if you have to go to the emergency room, but aren’t admitted to the hospital
  • the first 3 pints of blood you may require
  • Part A hospice care coinsurance or copayment
  • coinsurance for skilled nursing facility care
  • Part A deductible
  • 80 percent of foreign travel exchange (plan limits apply)

Note that some states standardize Medicare plans differently. These states include Massachusetts, Minnesota, and Wisconsin.

You can enroll in a Medigap plan when you are age 65 and enrolled in Medicare Part B. You can only have a Medigap plan if you have original Medicare.

You can’t have both Medicare Advantage (Part C) and Medigap at the same time. You must choose one if you want additional coverage.

Generally, the least expensive time to buy a Medigap policy is when you are in your Medigap initial enrollment period. This is a 6-month period that begins the month you are both age 65 or older and enrolled in Medicare Part B.

A company can not use medical underwriting during this initial enrollment period to sell you a policy. This means they cannot consider your overall health and medical conditions when they sell you a policy. The insurance company must sell you the policy for the same price they sell it to people who are in general good health.

You can still purchase a Medigap policy after your Medicare open enrollment period. However, you may have to complete a physical exam or answer other questions about your health before they allow you to purchase the policy. It’s also possible the insurance company could charge you more for the policy than they would to an otherwise healthy person.

People under age 65 also have Medicare. This is true if you have a disability or certain medical conditions, such as end stage renal disease. Your ability to purchase a Medigap policy under age 65 depends on the insurance company and your state’s insurance laws.

The government doesn’t sell Medigap policies. You’ll have to buy the policy from a health insurance company.

Once you’ve identified an insurer you may like to purchase the plan from, contact the company directly to apply for a policy.

The insurance company will then let you know what information they may need (such as for medical underwriting if you aren’t in an open enrollment period). If they approve you, they should give you an estimate of how much the monthly premium will be.
