Medicare gap refers to the coverage gap in Medicare drug plans, also known as the "donut hole"
. It is a temporary limit on what the drug plan will cover for drugs, which begins after you and your drug plan have spent a certain amount for covered drugs
. Medicare Supplement Insurance (Medigap) is extra insurance you can buy from a private health insurance company to help pay your share of out-of-pocket costs
. Medigap policies generally help cover your share of costs for services that are covered by Original Medicare (Part A and Part B)
. Medigap plans sold after 2005 do not include prescription drug coverage
