Oklahoma Attorney General Gentner Drummond's Medicaid Fraud Control Unit has concluded investigations in 10 counties, covering instances of fraud and abuse by health care providers. The investigation, Operation Sooner Shield, resulted in 10 arrests, two surrenders, 10 criminal cases, and one civil action. Charges include Medicaid fraud, exploitation of elderly persons or disabled adults, identity theft, and misuse of funds. Half of the investigation was dedicated to a civil action filed against the Neuropathy Treatment Clinic of Oklahoma LLC, the manager and indirect owner of James Warren Linn Jr. The lawsuit alleges that Linn and the clinic, which provides non-invasive energy waves to targeted areas of the body, engaged in a fraudulent scheme to bill Oklahoma Medicaid for services that were not rendered or medically necessary. The clinic allegedly received over $880,000 for allegedly fraudulent Carnitor claims since August 2021.
