When your compliance office flags a physician compensation arrangement that does not fit neatly into an existing exception, or your organization receives a subpoena referencing referrals for designated health services, the first question is which statute creates the exposure. The Stark Law and the Anti-Kickback Statute both govern financial relationships between providers and referral sources and both attach to claims billed to Medicare and Medicaid, but they rest on different legal theories, reach different conduct, and carry different penalties.
Strict Liability Versus Intent-Based Liability
The Stark Law, codified at 42 USC § 1395nn, imposes strict liability. A referral fitting the statute's definition of a prohibited financial relationship violates the law regardless of intent to influence referrals. Where a physician has a financial relationship, meaning ownership, investment, or compensation, with an entity and refers a patient to that entity for a designated health service payable by Medicare or Medicaid, the arrangement must fit within a specific regulatory exception or the resulting claims are not payable.
The Anti-Kickback Statute works differently. Codified at 42 USC § 1320a-7b(b), it is a criminal statute requiring the government to prove a defendant knowingly and willfully offered, paid, solicited, or received remuneration with intent to induce referrals of business reimbursable under a federal health care program. Absent proof of that intent, the statute does not apply.
Covered Referrals and Prohibited Remuneration
The regulated conduct differs as well. The Stark Law applies only to referrals made by a physician for one of an enumerated list of designated health services, such as clinical laboratory services, physical therapy, radiology, and durable medical equipment, billed to Medicare or Medicaid. The financial relationship need not involve cash: equipment leases, medical director agreements, and space rental arrangements all qualify if they fail to meet an exception's requirements.
The Anti-Kickback Statute reaches further. It covers remuneration of any kind, offered by any party, to induce referrals of any item or service reimbursable under any federal health care program, not limited to designated health services. Because the statute turns on intent, the government has published safe harbors at 42 CFR § 1001.952 shielding specific arrangements from prosecution. Our related article, The Anti-Kickback Statute: Remuneration, Intent, and Safe Harbors, reviews these categories.
Civil, Criminal, and Administrative Penalties
The penalty structures reflect the same divide. A Stark Law violation is remedied first through repayment: claims submitted in violation of the statute are not payable, and any amounts collected must be refunded. Under 42 CFR § 1003.310, the Department of Health and Human Services may also impose civil monetary penalties (adjusted periodically for inflation) of up to $15,000 per service billed in violation and up to $100,000 per arrangement or scheme that circumvents the law's requirements, plus program exclusion.
The Anti-Kickback Statute carries harsher exposure. A violation is a federal felony under 42 USC § 1320a-7b(b), punishable by a fine of up to $100,000 and imprisonment of up to 10 years for each violation. The statute also supports civil monetary penalties (also inflation-adjusted) of up to $100,000 per act of remuneration under the Civil Monetary Penalties Law, plus program exclusion. Both statutes can trigger liability under the False Claims Act, which allows treble damages atop any penalty.
Where Exposure Overlaps
Overlapping exposure under both statutes drives many of the healthcare fraud defense matters our attorneys handle. A compensation arrangement that fails a Stark Law exception is also a common Anti-Kickback Statute target where the government can show intent to reward referral volume. Since 2010, the Affordable Care Act has classified claims submitted in violation of the Anti-Kickback Statute as false claims under the False Claims Act. A single flawed arrangement can generate exposure under a strict liability statute, a criminal intent statute, and a civil fraud statute at once, and whistleblowers can bring qui tam actions under any of them.
One flawed financial relationship can violate a strict liability statute, a criminal intent statute, and the False Claims Act at the same time.
Why Early Legal Counsel Is Critical
It is critical that healthcare providers promptly retain experienced healthcare defense counsel upon receiving a subpoena, audit notice, investigative request, or other government inquiry touching on physician compensation or referral arrangements. Early legal intervention can protect the provider's rights, ensure appropriate responses to government requests, avoid inadvertent admissions, preserve relevant defenses, and allow counsel to communicate with investigators on the provider's behalf. Delaying legal representation can significantly affect the outcome of a matter and expose the provider to unnecessary risk.
