How many main categories are there in CPT?

The correct answer is that there are three main categories in the Current Procedural Terminology (CPT) system. These categories are crucial for coding medical procedures and services accurately.

The first category, Category I, comprises the majority of procedures and services that healthcare providers perform. These codes are five-digit numerical codes that describe a wide range of procedures performed by healthcare professionals.

The second category, Category II, includes supplemental tracking codes that are used for performance measurement. These codes are optional and can help in collecting information for patient management and quality improvement but do not directly impact reimbursement.

The third category, Category III, contains temporary codes for emerging technologies, services, and procedures. These codes are also five digits but are essential for the tracking of new services and their efficacy before they may become permanent in Category I.

Understanding the distinction between these categories is critical for accurate coding and for healthcare professionals to ensure proper documentation and billing practices.
