Why do you need an OIG check for a verified company?

The procedure of determining if a certain person or company is included on the HHS Office of Inspector General's List of Excluded Individuals and Entities (LEIE) is known as an "OIG check." It is against the law for excluded people to get compensation from any federally financed healthcare program, including Medicare, Medicaid, or SCHIP, regardless of how it is administered.
