The settlement was negotiated on Oklahoma's behalf by Edmondson's Patient Abuse and Medicaid Fraud Control Unit, which has statewide jurisdiction to investigate and prosecute provider fraud and patient abuse. The fraud claims were contained in lawsuits filed in U.S. District Court in Chicago by the federal government and two whistle-blowers who formerly were employees of Omnicare.
