Medigap Insurance 101

Posted by Medicare Made Clear

MedigapMedigap (also known as Medicare Supplement Insurance) is private health insurance that helps cover all or part of the costs that Medicare Parts A and B do not pay. Ten standard plans are available, labeled A through N. Not all plans are available in all states. There a different plans available in Massachusetts, Minnesota and Wisconsin.


Medigap coverage may be used for care anywhere within the United States with providers who accept Medicare patients. Some Medigap policies do offer a benefit for emergency care received outside of the United States. Depending on the plan chosen, some of the costs Medigap plans may help cover include:

  • Part A Deductable
  • Part B Annual Deductable
  • Hospital and skilled nursing coinsurance
  • Part B Coinsurance or co-pays
  • Blood Transfusions (first 3 pints)
  • Cost of additional 365 hospital days after you’ve used up your Part A benefits
  • Preventative care coinsurance costs
  • Foreign emergency medical benefits (up to plan limits)

Medigap Plans A through N

In most states, there are ten standard versions of Medigap policies. Unlike Medicare Parts C and D, Medigap plans are defined by the government. For example, there is no difference between the coverage provided by a Medigap Plan C, regardless of the company providing the insurance plan.


The cost of a Medigap plan can however differ from one insurance provider to another. Some companies offer a high deductable version of Plan F. Plans K and L use coinsurance to distribute costs between the beneficiary and the insurance company until you reach your out-of-pocket limit.

If you are currently researching Medigap for yourself or a loved one, be sure to review all the Medigap plans available in your area to determine which will meet your needs most effectively. To find out what plans are available to you, visit the Medicare website or contact your State Health Insurance Assistance Program (SHIP). If you already have a Medigap plan it is important to understand exactly what it covers in order to take full advantage of the benefits it provides. Please review the Certificate of Insurance carefully.
