Medicare supplement (Medigap) enrollment and regulations in Ohio

According to AHIP, there were 602,210 Ohio Medicare beneficiaries with Medigap coverage as of 2023.³

The Ohio Department of Insurance lists 59 insurers that are licensed to sell Medigap plans in Ohio, with contact numbers for each one. To see the list, click on “MedSup Plans” in the menu on this page.

Federal rules require Medigap insurers to offer plans on a guaranteed-issue basis during an enrollee’s Open Enrollment Period, which begins when the person is at least 65 years old and enrolled in Medicare Part A and Medicare Part B. But although 6.5 million Medicare beneficiaries are not yet 65 (and are enrolled in Medicare due to a disability) there is no federal requirement that Medigap insurers offer plans to people who are under age 65.

The majority of the states have addressed this with legislation that ensures at least some access to Medigap plans for people under age 65, but Ohio is not among them. Ohio’s Medicare guide notes that Medigap plans are available on a guaranteed-issue basis for six months after they’re at least 65 and enrolled in Medicare Part A and Part B,⁴ or when they have a federally mandated guaranteed-issue right.⁵
