Most people think Medicare is a government program. That’s only partly true. While Congress created Medicare, and continues to develop Medicare coverage and appeal rules, decisions to pay claims are actually made by private companies. The government does not make those decisions. This was one of the compromises made in order to pass Medicare in 1965 – and the public-private partnership continues to date.
Indeed, the entities granting or denying coverage, and those deciding whether or not to pay claims, are mostly private insurance companies. For example, Anthem is the parent company of “National Government Services,” one of the major Medicare claims administrators. Another Medicare administrative contractor, “MAXIMUS,” is a for-profit company that helps state, federal and foreign governments administer programs.
