![What Is Medigap Insurance?](https://money.com/img/logo-social.png)

Medicare provides a whole lot of coverage, but it doesn't cover everything. So some people choose to buy a separate policy to provide coverage for the areas Medicare falls short on. This is known as Medigap insurance. You buy Medigap from a private insurance company.

You can also use your Medigap policy to cover expenses you have under Medicare, such as annual co-pays and deductibles.

Important note: If you opt for a Medicare Advantage Plan ([Medicare Part](https://money.com/what-is-medicare/)), any Medigap policy you have won't pay out. So if you decide to move into a Medicare Advantage Plan and you already have a Medigap policy, drop the Medigap.
