In what year was the CPT coding system first developed?

The CPT coding system was first developed in 1966 by the American Medical Association (AMA). This was a significant year because it marked the creation of a standardized coding system for reporting medical, surgical, and diagnostic procedures and services. The primary goal of establishing CPT codes was to improve the accuracy of billing and ensure clarity in documentation within the healthcare system. Over the years, the system has undergone numerous updates and revisions to reflect advancements in medical science and changes in healthcare practices, but its origins date back to 1966, making this answer correct.
