The American Osteopathic Association’s (AOA) first edition “Guide to Coding & Documentation: Osteopathic Manipulative Treatment” serves as a comprehensive reference guide for physicians and their practices. It offers practical advice, best practices, and resources on clinical coding and medical records documentation for Osteopathic Manipulative Treatment (OMT) procedures and same-day Evaluation & Management (E/M) services to prevent delayed reimbursement, avoid claims denials and/or protect yourself in the event of an audit. Content has been developed by an expert panel of osteopathic physicians in conjunction with AOA staff with subject matter expertise in coding and documentation, practice management and payor relations.
