Medicare Supplement Insurance, also known as "Medigap" insurance, provides supplemental health insurance coverage for Medicare beneficiaries. Individuals in the "original" Medicare program may want to obtain Medicare Supplement ("Medigap") insurance because Medicare often covers less than the total cost of the beneficiary's health care.
Medicare is divided into two coverage components, Part A and Part B. Both programs have gaps in coverage that may be covered by supplemental insurance.
