Medical billers and coders have different roles, but they do work closely together. Depending on where you work, the audits may be conducted by an internal or external auditor. Patient records receive periodic audits to ensure the accuracy of the medical codes. Medical coders must also ensure the accuracy and privacy of records. These professionals help improve communication between healthcare teams, electronic health records (EHR) systems, insurance companies, and other payers.
