Medicare Supplement Insurance plans (also called Medigap) are sold by dozens of private insurance companies all over the U.S. When shopping for coverage, it’s important to find the right plan for your unique needs and also to find the right insurance company. 

Different companies may sell Medigap plans that have different prices and terms, and each insurance company has an individual reputation you may want to consider.

Below is a guide to 10 Medicare Supplement Insurance companies to help you choose the best one for your needs. 

Comparing Medicare Supplement Insurance Companies

The list below includes some of the companies that sell Medicare Supplement Insurance plans in select states across the U.S.

Please note that our guide is meant to be informational and to help you as you start finding the right plan and plan carrier for your needs. Some of the companies listed below may not offer Medigap plans in your area, and you may find a Medicare Supplement carrier in your area that fits your need and isn’t on this list.

This list identifies several of the top 10 insurance companies in no particular order. 

• Humana
• Cigna
• Blue Cross Blue Shield
• Aetna
• ManhattanLife
• Mutual of Omaha
• Medico Insurance Company
• WellCare

It’s important to keep in mind that although each company’s plan selection and pricing may differ, the coverage included in each type of Medigap plan remains the same, no matter where you purchase it.

In other words, Medigap Plan A sold by one company will include the same essential benefits as Medigap Plan A sold by any other insurance company. Their costs and the availability of the types of plans, however, may vary.

Medigap plans in Massachusetts, Minnesota and Wisconsin are standardized differently than they are in every other state.
