Final answer:
Medigap insurance is not sold or serviced by the federal government; it is sold by private insurance companies to supplement Medicare coverage.
Step-by-step explanation:
The statement that Medigap insurance, intended to supplement Medicare, is sold and serviced by the federal government is False. Medigap, also known as Medicare Supplement Insurance, is a type of insurance policy that is sold by private insurance companies to cover costs not covered by Medicare, such as deductibles, copayments, and coinsurance. Medicare is a federal program that provides health insurance to people over the age of 65, certain younger people with disabilities, and people with End-Stage Renal Disease. While Medicare Part A and Part B (often called 'Original Medicare') are provided by the federal government, Medigap policies are offered by private insurers as additional coverage.
