CPT Book classifications
The CPT book comprises of Level I HCPCS codes maintained by American Medical Association classified these codes into six major groups,
1. Evaluation and Management (E/M) Codes starts from 99201 to 99499
2. Anesthesiology Codes starts from 00100 to 01999
3. Surgery Codes starts from 10000 to 69990
4. Radiology Codes starts from 70010 to 79999
5. Pathology and Laboratory Codes starts from 80002 to 89399
6. Medicine Codes starts from 90281 to 99607
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.
The CPT code range and its sub-classifications are detailed as follows
