Advanced Imaging of Port Charlotte, LLC, a radiology center headquartered in Port Charlotte, Florida, has agreed to pay $501,000 to resolve allegations that it violated the False Claims Act by submitting fraudulent claims to Medicare and Tricare, a healthcare program for uniformed service members, retirees, and their families. As part of the settlement, the United States contends that Advanced Imaging knowingly submitted claims to Medicare and Tricare by (1) administering dye-contrast scans without direct physician supervision as required by Federal regulations and (2) improperly billing for services performed by doctors who were not properly credentialed by Medicare.
