A medical coding auditor is an administrative professional in the healthcare industry. As a medical coding auditor, you check medical coding and billing information for accuracy, suspicious activity, and compliance with healthcare regulations. Your responsibilities require you to review medical data and document any areas where the medical coding could improve in terms of accuracy and efficiency. Your duties also include reviewing records of patients to make sure that there is documentation for each item on a billing inventory. Though you work in the medical coding and billing department, your focus is on regulations, compliance, and efficiency rather than on coding for billing and records purposes.
