Medicare supplemental insurance, also known as "Medigap," is an important source of supplemental coverage for nearly one in four people on Medicare. Traditional Medicare has cost-sharing requirements and significant gaps in coverage; Medigap helps make health care costs more predictable and stable for beneficiaries by covering some or all Medicare costs, including deductibles and cost-sharing.
As part of several debt-reduction and Medicare-reform proposals, some policymakers propose to prohibit Medicare supplemental insurance policies (known as Medigap) from covering all of enrollees' out-of-pocket Medicare costs, which some believe leads to higher use of services and higher Medicare spending.
