The federal statute under which false billing to Medicare or Medicaid carries treble damages and per-claim penalties, and the qui tam procedure that lets a private person sue in the government's name and share the recovery.
The False Claims Act makes it unlawful to knowingly present, or cause to be presented, a false or fraudulent claim for payment to the federal government, to make a false record material to such a claim, or to knowingly retain an overpayment. In health care it reaches billing for services not provided, upcoding, billing medically unnecessary services, claims tainted by kickbacks or a Stark violation, and false certifications of compliance with conditions of payment. "Knowingly" includes deliberate ignorance and reckless disregard, so a provider who ignored obvious billing problems is covered, while an honest mistake is not. Liability is treble the government's damages plus a penalty for each false claim, which is why exposure is calculated per claim submitted and can dwarf the amount actually overpaid.
The qui tam provision allows a private person - a relator, in practice usually an employee, a billing contractor, a competitor or a physician - to file a sealed complaint in the government's name. The government investigates while the case is sealed and decides whether to intervene and take over; if it does, the relator receives a share of the recovery in a lower band, and if it declines the relator may proceed alone for a larger share. Most recoveries come from intervened cases and most are settled. The Act also protects an employee, contractor or agent from retaliation for lawful acts in furtherance of a false claims case, with reinstatement, double back pay and fees as remedies.
Two doctrines limit it. The falsity must be material to the government's decision to pay: the Supreme Court has held that a violation the government knew about and paid anyway, or a minor regulatory breach, does not support liability, and that implied certification requires a misleading half-truth about compliance. And the first-to-file and public-disclosure bars mean that a relator whose allegations are already in a filed case or in the public record generally cannot recover unless they are an original source. State false claims acts, in most states, run in parallel for Medicaid claims.
A person who believes their employer is billing the government falsely should speak to a whistleblower lawyer before speaking to anyone else, including the employer's compliance line, because the timing and content of the sealed filing determine whether they are first to file, whether they are an original source, and what share they may receive - and because retaliation protection depends on what they did and when. A provider that receives a civil investigative demand or learns a sealed case exists needs counsel immediately and should preserve every record.
