You are the chief nurse executive at an organization that provides clinic services to Medicare patients; seven of the clinics are located in underserved areas. While visiting one of the clinics, you perform a routine audit. You notice that one physician, who has been excluded from the Medicare program due to a prior felony conviction for accepting kickbacks for referrals, has submitted bills for $165,000 for services rendered. You contact the physician and she refers you to her attorney. Her attorney says she thought she was following the law when she submitted bills for services her employee performed. The patients received the services and there have been no reported complaints. The physician speaks three languages fluently, and the patients at this clinic have nothing but praise for her care. You have had a great deal of difficulty locating a qualified physician who is willing to work in this crime-ridden area. What should you do in this situation?
