Medigap Billing and Claims Questions

Most Medigap policy owners will find that their Medicare-covered costs require little to no paperwork on their part.

If you have questions about specific Medicare-covered expenses or a specific claim, please review the documentation that came with your policy and contact your medical care provider first.
