Memphis Doctor to Pay $375,296.90 to Settle Fraudulent Billing Allegations

Memphis, TN – A Memphis nephrologist providing end-stage renal disease, or ESRD, treatments to Medicare beneficiaries will pay $375,296.90 to resolve False Claims Act allegations brought against him. D. Michael Dunavant, United States Attorney for the Western District of Tennessee, announced the agreement today. Dr. Mark Shermer was alleged to have falsely billed Medicare for ESRD treatment visits to dialysis patients that he never actually performed. The civil settlement resolved these allegations brought under the qui tam or whistleblower provisions of the federal False Claims Act. Under the qui tam provision, a private party can file an action on behalf of the United States and receive a portion of the settlement if the government takes over the case and reaches a monetary agreement with the defendant. The case is captioned United States ex rel. Davis, 2:21-cv-2754-JTF-cgc (W.D. Tenn.).
