Q. What's the difference between Medicare Advantage and Medigap?
Private insurance companies like Humana sell both Medicare Advantage plans and Medicare Supplement plans - which are also referred to as Medigap plans. However, they're not the same. Humana's Group Medicare Advantage plans combine the benefits of Original Medicare and Medicare supplements in a single plan that Humana underwrites and administers. Medicare Supplement plans work with Original Medicare, filling gaps in coverage such as deductibles.
Unlike Group Medicare Advantage plans, Medicare Supplement plans aren't available at the group level. However, secondary coverage is available to groups.
