Physician Convicted of Conspiracy to Defraud Medicare

NEW ORLEANS to Acting United States Attorney Michael M. Simpson announced that DR. MARION LEE (“LEE”) , age 62, of Cordele, Georgia, pled guilty on October 8, 2025 to conspiracy to defraud the United States, in violation of 18 U.S.C. § 371, in connection with a scheme to bill Medicare approximately $24 million for medically unnecessary genetic testing, and to pay and receive kickbacks. According to court documents, LEE , co-owner of and medical advisor to Luminus Diagnostics, a diagnostic laboratory located in Tifton, Georgia, conspired with others to procure orders for genetic testing in exchange for kickbacks, including orders acquired through purported telemedicine. To ensure the false and fraudulent claims would be paid, LEE and his co-conspirators designed the genetic testing order forms to be “dummy proof”, with prepopulated diagnosis codes and check-the-box panels, and frequently billed the tests through another laboratory in the Eastern District of Louisiana where co-conspirators thought the claims were more likely to be approved. The co-conspirators concealed these claims via a sham contract, among other deceptive means. LEE and his co-conspirators caused the submission of over $24 million in false and fraudulent claims to Medicare for genetic testing, and Medicare paid approximately $4 million based on those claims. Under the terms of LEE ’s plea agreement, LEE agreed to over $4 million in restitution owed to Medicare. The Honorable Lance M. Africk set sentencing for March 18, 2026. At sentencing, the maximum penalty LEE may receive is five years of imprisonment, followed by up to three years of supervised release. He also faces a fine of up to $250,000, and payment of a mandatory special assessment fee of $100. Acting U.S. Attorney Simpson praised the work of the Department of Health and Human Services Office of Inspector General and the Federal Bureau of Investigation in investigating this matter. Assistant United States Attorney Nicholas D. Moses, of the Financial Crimes Unit and Health Care Fraud Coordinator, and Trial Attorney Kelly Z. Walters, of the Department of Justice’s Criminal Division’s Fraud Section, are in charge of the prosecution.
