What is Medicare Supplement Insurance?

Medicare Supplement insurance is a private health insurance policy designed to fill in the gaps and help pay deductibles, copayments and coinsurance that Medicare leaves you to pay. Often referred to as “Medigap insurance,” it is different from a Medicare Advantage plan because you remain in original Medicare.

Medigap policies are sold by private insurers. The policies are standardized and are identified by letters (plans A through L). The benefits of each insurer’s Medigap plans must be the same so you can easily compare price.

Quick Facts – Medicare Supplement Insurance

  • Covers some of the health costs not covered by original Medicare Parts A and B
  • You’re eligible if enrolled in both Part A and Part B
  • Monthly Medicare Supplement Insurance premiums apply, and you must continue to pay your Part B premium
  • A Medicare Supplement policy covers only one person. If you and your spouse both want Medicare Supplement Insurance, you must buy separate policies.
  • In most cases offers freedom to choose doctors, hospitals and other health professionals
  • Deductibles and coinsurances may apply
  • Enrollment in Medicare Supplement Insurance is optional
