11. What is Medigap?

People who choose Original Medicare may wish to consider Medigap, a type of Medicare supplement insurance. Medigap policies are sold by private insurance companies to fill gaps in Original Medicare Plan coverage, such as out-of-pocket costs for Medicare co-insurance and deductibles, or for services not covered by Medicare. A Medigap policy only works with Original Medicare. A person who joins a Medicare Advantage Plan generally doesn't need (and can't use) a Medigap policy.
