Evidence Trails in Complex Fraud Investigations

Evidence Trails in Complex Fraud Investigations at a Glance

In complex fraud investigations, particularly under the Anti-Kickback Statute (AKS) and the False Claims Act (FCA), the establishment of a clear and verifiable evidence trail is essential. These trails typically consist of documentary, electronic, and testimonial evidence that demonstrate the existence of a payment-for-referral relationship. Such evidence is the cornerstone of proving violations under 42 U.S.C. § 1320a-7b(b) and 31 U.S.C. §§ 3729–3733, which are central to anti-kickback and referral law enforcement.

The Legal Framework

The Anti-Kickback Statute, 42 U.S.C. § 1320a-7b(b), criminalizes the knowing and willful offer, payment, solicitation, or receipt of remuneration to induce or reward referrals of items or services payable by a federal health care program. Violations can result in severe penalties, including fines of up to $100,000 and imprisonment of up to 10 years, or both. The statute applies broadly and does not require proof of actual harm or loss to the federal program, making it a powerful tool for enforcement.

The False Claims Act, codified at 31 U.S.C. §§ 3729–3733, provides a civil remedy for individuals or entities that submit false claims to the government. A key feature of the FCA is the qui tam provision, which allows private citizens—known as relators—to bring actions on behalf of the government. In such cases, the relator is entitled to a share of the proceeds: 15–25% if the government proceeds with the action, 25–30% if the government declines, and no more than 10% if the action is based primarily on public disclosures.

The Federal Overlay

The federal Anti-Kickback Statute, 42 U.S.C. § 1320a-7b(b), makes it a felony to knowingly and willfully offer, pay, solicit, or receive remuneration to induce or reward referrals of items or services payable by a federal health care program. The Stark Law, 42 U.S.C. § 1395nn, separately prohibits physician self-referrals for designated health services payable by Medicare or Medicaid, on strict-liability terms. Both regimes carry safe harbors and exceptions published at 42 C.F.R. § 1001.952. State referral and fee-splitting statutes operate alongside these federal prohibitions and can apply even where no federal program payment is involved.
