Medigap Policies

A Medigap policy is a health insurance policy sold by private insurance companies to fill "gaps" in Original Medicare Plan coverage. Every Medigap policy must follow federal and state laws designed to protect you, and they must be clearly identified as “Medicare Supplement Insurance.” Insurance companies can sell you only a “standardized” policy identified in most states by letters A through D, F through G, and K through N. All policies offer the same basic benefits, but some offer additional benefits so you can choose which one meets your needs. In Massachusetts, Minnesota, and Wisconsin, Medigap policies are standardized in a different way..

Outline of Medicare Supplement Coverage

(Benefit Plans A-N)

The chart below shows basic information about the different benefits that Medigap policies cover. If a percentage appears, the Medigap plan covers that percentage of the benefit, and you’re responsible for the rest. Some plans may not be available in your state as indicated below.

*Plan F also offers a high-deductible plan in some states. If you choose this option, this means you must pay for Medicare-covered costs (coinsurance, copayments, and deductibles) up to the deductible amount of $2,340 in 2020 before your policy pays anything.

**For Plans K and L, after you meet your out-of-pocket yearly limit and your yearly Part B deductible ($198 in 2020), the Medigap plan pays 100% of covered services for the rest of the calendar year.

***Plan N pays 100% of the Part B coinsurance, except for a copayment of up to $20 for some office visits and up to a $50 copayment for emergency room visits that don’t result in an inpatient admission.
