Medigap

Supplemental insurance sold by private companies to fill 'gaps' in Original Medicare coverage.

What It Is

Medigap (Medicare Supplement Insurance) is extra insurance you can buy from a private health insurance company to help pay your share of out-of-pocket costs in Original Medicare.

Why It Exists

Original Medicare pays for much, but not all, of the cost for covered health care services and supplies. A Medigap policy can help pay some of the remaining health care costs, like:

  • Copayments
  • Coinsurance
  • Deductibles
