The U.S. Department of Justice announced federal charges against the owner of Spring Hill-based Crestar Labs, a self-described "diagnostic reference laboratory," who federal prosecutors allege was involved in a fraudulent Medicare billing scheme. According to a news release from the United States Attorney's Office for Middle District of Tennessee, 53-year-old Fadel Alshalabi, of Waxhaw, N.C., who serves as both Crestar's owner and chief executive officer, was charged with aiding and abetting as well as with violating the federal anti-kickback statute when he was arrested in Chicago on Sunday. Prosecutors allege that, as early as 2016, Alshalabi engaged in a scheme to pay illegal health care kickbacks in exchange for the solicitation of genetic tests from Medicare beneficiaries.Â
