These set of CPT codes in each groups are organized into various categories and levels. It is the physician’s responsibility to ensure that documentation reflects the services furnished and that the codes selected reflect those services. The more work performed by the physicians, the higher the level of code they may bill within the appropriate category. The billing specialist or alternate source reviews the physician’s documented services and assists with selecting codes that best reflect the extent of the physician’s personal work necessary to furnish the services.
