Which categories are found in the CPT coding system?

The CPT coding system is organized into three distinct categories, making the selection of Category I, Category II, and Category III accurate.

Category I includes the most commonly used codes for procedural services and is subdivided into surgical procedures, radiology, pathology, and evaluation and management services. These codes are widely recognized and used by healthcare providers across various clinical settings.

Category II codes are supplemental tracking codes that are optional and used for performance measurement. They help in the collection of data for improving patient care without impacting reimbursement.

Category III codes are temporary codes for emerging technologies, services, and procedures that are not yet widely accepted or have not yet been assigned a permanent Category I code. They play a crucial role in providing a mechanism for tracking new procedures and services.

This structure is essential for maintaining an organized and efficient system for coding medical procedures, thus enabling accurate communication between healthcare providers and payers, and ensuring proper reimbursement for services rendered.
