What Is Medicare Supplement?

Medicare Supplement Insurance, or Medigap, are insurance plans that help pay for out-of-pocket Medicare costs like deductibles and copays. Medigap plans are standardized by the federal government. That means the coverage provided by a particular type of Medigap plan will be the same, no matter where the plan is sold or by whom.

Here is a comparison chart showing the standardized 2025 Medicare Supplement plans available in most states.

  • Not all insurance companies maintain the same consumer or financial ratings.
