qui tam

(kwī tam) [L., who as well, who also]
A legal claim or type of litigation in which an individual alleges fraudulent billing by a government contractor. Funds recovered by the government as a result of the claim are divided between the government and the relator of the action. The government is entitled to most of the fraudulently obtained money, and the “whistleblower” is given a percentage of the recovered funds as a reward. Qui tam litigation is one way the U.S. government combats Medicare fraud and abuse.
