The United States has partially intervened in a False Claims Act lawsuit against William M. Kelly, MD Inc. and Omega Imaging Inc. in the US District Court for the Central District of California. The government intervened as to allegations that the defendants, which operate 11 radiology facilities in Southern California, violated the False Claims Act by submitting claims to Medicare for unsupervised radiology services and services provided at unaccredited facilities. The lawsuit alleges that that defendants performed and billed Medicare for contrast procedures without the proper physician supervision. The suit further alleges that certain of the defendants’ facilities lacked accreditation, which is a material Medicare billing requirement. The case was filed under the qui tam or whistleblower provisions of the False Claims Act Act, which allow private parties to file suit on behalf of the United States for false claims and to receive a share of any recovery.
