Q. What's the difference between Medicare Advantage and Medigap?
Medicare Advantage plans aren't the same as Medicare Supplements – also referred to as Medigap plans. Like Medicare Advantage plans, private health insurance companies sell Medicare supplement plans. Keep in mind that Medicare Supplement plans aren't available at the group level. However, secondary coverage is available to groups.
For more details about secondary coverage, including Retiree Wrap plans, see Other Medical Coverage.
