Auto coding, in the context of medical coding, refers to the automated process of assigning diagnostic and procedural codes to patient encounters or medical records. It involves utilizing advanced technologies, such as Natural Language Processing and machine learning algorithms, to analyze and interpret clinical documentation. By extracting relevant information from medical records, auto coding systems can accurately assign the appropriate codes based on established coding guidelines and rules. This automation not only improves coding accuracy and consistency but also saves time and reduces manual effort in the medical coding process.
