California medical supplier American Medical Technologies Inc. is preparing to leave bankruptcy protection after more than three years, the bulk of which were spent settling a $76 million billing dispute with federal health care regulators, Dow Jones Daily Bankruptcy Review reported today. With a two-page court order, Bankruptcy Judge Mark S. Wallace signed off on American Medical's turnaround plan on Wednesday, enabling company officials to put their debt-repayment plan into action. The plan calls for the Irvine, Calif., company to pay Medicare and Medicaid administrators a total of $35 million over the next seven years to settle accusations that the company took in money for equipment and services that weren't covered by the Medicare Act.
