Katten's Health Care Litigation, Reimbursement and Regulation team members have spent their careers deeply immersed in the health care industry and have gained the experience and knowledge necessary to help clients assess, initiate, strategically navigate and resolve disputes in a complicated and oft-changing regulatory environment. We leverage that experience, coupled with our knowledge of the dispute resolution processes, to help clients assess the benefits and risks of avoiding or pursuing litigation in state or federal court, settling a dispute or seeking other forms of relief within the regulatory system. And our litigators do not practice in a silo but, rather, are core members of our broader Health Care group, working closely with attorneys from our Health Care Regulatory and Compliance and Health Care Transactions teams on our clients' most significant matters.

Types of disputes

Our team represents a broad range of clients across the health and life sciences sectors in a wide range of disputes and investigations. We have litigated matters at the administrative agency level as well as in state and federal courts across the country, including in the US Supreme Court and in most federal circuit courts of appeals. We work closely with the Health Care Regulatory and Compliance and Health Care Transactions teams to assess and handle disputes involving a number of issues, including commercial disputes involving the health care industry, claims under the False Claims Act (FCA), cases involving allegations of fraud and abuse, alleged violations of the Anti-Kickback Statute, federal physician self-referral law (Stark Law), qui tam actions, reimbursement issues, and many others.

Our Health Care litigators are frequently involved in civil and criminal actions brought by government enforcement agencies, arising from investigations into Medicare fraud, whistleblowing, false claims and the like. The team includes former federal prosecutors who specialized in health care fraud and abuse matters when they served in US Attorneys' Offices and in the US Department of Justice, which proves valuable to clients as we engage with government attorneys in high stakes matters.

"They are highly qualified, accessible and responsive. The quality of work is fabulous, and the juniors there are also very good."
