The Qui Tam process is a process of reporting abuses to Medicare or other types of government supplement aid. In general, when a business provides a service or provides care to a patient who is covered under a governmental plan, the business will then report the costs and accurately bill the government for them. However, in some instances of Medicare fraud, the business will inflate the cost of the service since the government is paying for it. Doing this is illegal and it constitute a legal case in many situations. The qui tam process simply is the reporting process.
