General Recommendation codes are most common.
The Current Procedural Terminology (CPT) manual contains three main categories of codes: Category I, Category II, and Category III. Category I codes are the most commonly used and represent procedures and services. Category II codes are optional tracking codes used for performance measurement, while Category III codes are temporary codes for emerging technologies and procedures. In total, there are thousands of specific codes within these categories.
The correct order from largest to smallest division of the Current Procedural Terminology (CPT) hierarchy is: Category I codes, Category II codes, and Category III codes. Category I codes are the most comprehensive and cover a wide range of medical procedures and services. Category II codes are supplemental tracking codes for performance measures, while Category III codes represent temporary codes for emerging technologies, services, and procedures.
