Medicare Supplemental Insurance (Medigap)

This type of policy helps to pay some of the health care costs that Original Medicare doesn't cover, like:

  • Co-payments
  • Coinsurance
  • Deductibles

Medigap policies are sold by private companies. 

Some Medigap policies also cover services that Original Medicare doesn't cover, like medical care when you travel outside of the U.S. If you have Original Medicare and you buy a Medigap policy, here's what happens:

  • Medicare will pay it's share of the Medicare-approved amount for covered healthcare costs. Then, the Medigap policy pays it's share.
