A compliance officer and committee will:Audit and monitor complianceDevelop written policies and procedures that are consistent with regulations and lawsProvide ongoing communication and training to staffRespond to and correct errorsAvoiding Fraud: Coding Compliance (cont.)23The insurance representative has questioned the codes listed on three patient forms that were submitted last year. When re-checking these forms the office medical assistant should:Use the current book to validate accuracy of the codes.Use last year’s book to validate accuracy of the codes.Use next year’s book to validate accuracy of the codes.
