Who Offers Medigap Coverage? 
Medigap or Medicare Supplement insurance coverage is offered by private insurance companies . All Medigap Plans are standardized , so the benefits with Plan F from ABC insurance company are the same exact benefits with XYZ insurance company . The only difference is the price . Often times , Seniors are only aware of a few insurance companies that offer Medigap Plans . This is because of their heavy marketing techniques . In reality , there are many more insurance companies available and probably most of them you 've never heard of -- but since Medigap Plan benefits are standardized by CMS , it does n't matter what the name of the insurance company is . An independent agent specializing in Medicare Supplement insurance can share which insurance companies are in your area and which ones have the best price . Thank you for reading my response . Please let me know if I can help you find Medigap coverage in your area .
