On January 6, 2025, the U.S. District Court for the District of Massachusetts granted a defendant laboratory’s motion for summary judgment in a False Claims Act (FCA)/Anti-Kickback Statute (AKS) case brought by a physician objecting to the lab’s testing practices and its use of independent contractors paid on commission. Judge Patti B. Saris held that plaintiffs in FCA cases must establish that “but for” the payment of illegal remuneration in violation of the AKS, the claim would not have been submitted. Applying the “but-for” standard, Judge Saris dismissed OMNI Healthcare Inc. v. MD Spine Solutions LLC, et al. because the record did not support that the independent contractor status of some of the lab’s sales representatives or their conduct unduly influenced any provider’s decision to purchase the product.

Adoption of “But-For” Causation in FCA Cases

There is a circuit split regarding whether FCA plaintiffs must prove that “but for” the AKS violation, a claim would not have been submitted. Requiring “but-for” causation poses a significantly greater burden for plaintiffs seeking to advance FCA claims because they must show the kickback actually affected what good, item, or service was provided.

In the U.S. Courts of Appeals for the Sixth and Eighth Circuits, the heightened “but-for” causation must be established. The Third Circuit has adopted a less rigorous standard, requiring only a showing that at least one of the claims sought reimbursement for medical care that was provided in violation of the AKS. Plaintiffs in circuits with no clear precedent often argue for the application of the more plaintiff-friendly standards of the Third Circuit and use that ambiguity as leverage in negotiating settlement agreements.
