What is the main purpose of the CPT codebook?

The primary purpose of the CPT (Current Procedural Terminology) codebook is to assign codes for medical procedures and services. This coding system facilitates precise communication among healthcare providers, insurers, and policymakers. By using standardized codes, it ensures that medical procedures, services, and treatments are consistently recorded and billed, which is essential for accurate billing and reimbursement processes.

Moreover, CPT coding helps in maintaining comprehensive medical records and can be invaluable for research and data collection purposes, allowing for the analysis of healthcare trends and practices. While the CPT codebook does contain some definitions and guidelines, its main function is to provide a systematic methodology for coding the vast array of medical services and procedures performed by healthcare professionals.
