We represented a global for-profit health insurance company with more than 20 million members in False Claims Act (FCA) litigation in federal court in the Northern District of Illinois. The case was initiated by a whistleblower who alleged that a contractual relationship between a pharmacy benefit manager and pharmaceutical manufacturer violated the Anti-Kickback Statute (AKS), resulting in the submission of false claims to Medicare Advantage plans. After a lengthy investigation and advocacy by our litigation team, the government declined to intervene in the lawsuit. The whistleblower decided to proceed, and we represented the client in years of contentious litigation, which resulted in a favorable settlement for our client while dispositive motions were pending.
