A recent Massachusetts Federal District Court decision adds to divergent opinions deciding an important health care enforcement question: what causation standard applies to a False Claims Act (FCA) case based on a violation of the Anti-Kickback Statute (AKS)? The AKS states that a claim that includes items or services “resulting from” a violation of the AKS constitutes a “false or fraudulent claim” under the FCA. 42 U.S.C. § 1320a-7b(g).
