CHICAGO — Joel R. Levin, Acting United States Attorney for the Northern District of Illinois, today announced the creation of a new unit dedicated to the prosecution of criminal health care fraud violations. The newly created Health Care Fraud Unit will operate within the office’s Criminal Division. The unit will be tasked with prosecuting defendants in all types of health care fraud, from providers who engage in fraudulent billing schemes to doctors who falsify patients’ diagnoses to justify expensive tests or procedures that aren’t medically necessary.
