District of Massachusetts Adopts But-For Causation Test for FCA Claims Premised on AKS Violations
As reported last week here, the Chief Judge of the District of Massachusetts held that a claim “result[s] from” a kickback only if the defendant would not have included particular items or services in the claim but for the kickback. United States v. Regeneron Pharma., Inc., No. 20-11217-FDS (D. Mass. Sept. 27, 2023). In so holding, the court aligned itself with decisions in the Sixth and Eighth Circuits, and rejected the Third Circuit’s looser standard that a false claim “result[s] from” a kickback where a patient was merely “exposed to an illegal recommendation or referral” and a physician submitted a claim “pertaining to that patient.” We have previously reported on this circuit split here and here.
District of Massachusetts Adopts But-For Causation Test for FCA Claims Premised on AKS Violations
On September 27, 2023, the District of Massachusetts, assessing the causation standard linking Anti-Kickback Statute violations to FCA liability, determined that a claim “result[s] from” a kickback only if the defendant would not have included particular items or services in the claim but for the kickback. We have previously written about the circuit split on this issue here and here. We will follow up with an additional post describing the court’s opinion, available here, in greater detail.
Court Certifies Interlocutory Appeal to First Circuit on Causation Standard Connecting AKS Violations and the FCA
Last week a court in the District of Massachusetts took the rare step of allowing an FCA defendant to pursue an interlocutory appeal arising from the summary judgment stage of an FCA case in which DOJ is seeking $10 billion in damages and penalties. The question on appeal asks the First Circuit to take a side in an expanding circuit split on the requisite causation requirement for AKS violations to trigger FCA liability.
DOJ Reaches Settlement with Laboratory Over Commission-Based Compensation Arrangements with Independent Contractors, Medical Necessity
Earlier this month, the U.S. Department of Justice (“DOJ”) announced a $5.9 million FCA settlement resolving allegations that Genotox Laboratories Ltd., a toxicology and pharmacogenetics testing laboratory: 1) violated the Anti-Kickback Statute (“AKS”), and thereby caused the submission of false claims, through commission-based compensation arrangements with its independent contractors, and 2) submitted claims to federal healthcare programs for unnecessary drug tests. In parallel proceedings, the U.S. Attorney’s Office for the Western District of Texas and Genotox entered into an eighteen-month Deferred Prosecution Agreement to resolve a criminal investigation into the same conduct. The settlement highlights DOJ’s ongoing interest in pursuing independent contractor arrangements that do not fit within a safe harbor to the AKS, where such relationships are also accompanied by conduct that traditionally attracts enforcement scrutiny, such as submission of claims for medically unnecessary services.
Sixth Circuit Adopts Limited Definition of AKS “Remuneration,” Robust Standard for Causation in AKS Qui Tams
On March 28, 2023, the Sixth Circuit issued a notable decision rejecting broad theories from DOJ and relators about (1) the definition of remuneration under the Anti-Kickback Statute (AKS) and (2) the causation requirement for AKS violations that trigger FCA liability. See United States ex rel. Martin v. Hathaway, No. 22-1463 (6th Cir. 2023). On the first, the court held that “remuneration” under the AKS “covers just payments and other transfers of value,” not “any act that may be valuable to another.” On the second, the court held that FCA liability attaches only if the claim would not have been submitted but for the AKS violation.
DOJ Reaches Settlement with OraPharma, Inc., Pushing Novel AKS Theory
Earlier this month the U.S. Attorney’s Office for the District of Massachusetts announced a $100,000 FCA settlement resolving novel allegations that a pharmaceutical company violated the Anti-Kickback Statute (“AKS”), and thereby caused the submission of false claims, through incentive compensation payments to its employees for conduct outside the scope of the employee relationship.
Court Rejects Application of the Public Disclosure Bar Due to DOJ’s Opposition
On January 24, 2023, the United States District Court for the Middle District of Florida denied a motion to dismiss a qui tam suit premised on Anti-Kickback Statute (“AKS”) allegations, explaining that it could not dismiss the case because DOJ and several interested states had filed oppositions to application of the public disclosure bar. See United States ex rel. Marcus v. BioTek Labs, LLC, No. 8:18-cv-2915 (M.D. Fla. Jan. 24, 2023).

Fourth Circuit Underscores the Risk of Commission-Based Compensation Agreements with Independent Contractors
In a recent decision, the Fourth Circuit Court of Appeals for the second time in two years held that commission-based compensation arrangements with independent contractors cannot be safe harbored and do violate the Anti-Kickback Statute and FCA. See United States ex rel. Nicholson v. Medcom Carolinas, Inc., No. 21-1290 (4th Cir. July 21, 2022).
Eighth Circuit Holds that AKS Violations Do Not “Taint” All Claims
The Eighth Circuit Court of Appeals recently issued a notable decision that offers defendants in FCA cases premised on violations of the Anti-Kickback Statute (“AKS”) significant new defenses relating to causation. The panel soundly rejected the government’s position that as a result of the 2010 amendments to the AKS, any claim provided in violation of the AKS is tainted, and therefore “false,” under the FCA. Instead, the Eighth Circuit held that for an AKS violation to render a claim false, the kickback must have been the but-for cause of the submission of the claim. United States ex rel. Cairns v. D.S. Medical LLC, No. 20-3010, 2022 WL 2930946 (8th Cir. July 26, 2022). The decision creates a circuit split with the Third Circuit and given the many courts of appeal that have not weighed in on this question, promises to generate renewed debate in district courts across the country as to the appropriate causation standard in FCA cases involving alleged violations of the AKS.
Recent Settlement Illustrates Enforcement Risks Associated With Physician Roll-Ups
On December 2, 2021, the Department of Justice (“DOJ”) issued a press release announcing that Flower Mound Hospital Partners (“Flower Mound”), a partially physician-owned hospital, agreed to pay just over $18 million to resolve allegations that it had violated the False Claims Act by submitting claims that violated the Stark Law and the Anti-Kickback Statute.
