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.

Category III codes have 3 digits and one Alpha. For example, 0019T. They are temporary codes for emerging technology, services, and procedures (taken from CPT 2011).
Category III Codes report emerging technology and are temporary codes used for up to 5 years.
Category III codes include new or rare procedures. These may be incorporated as Category I codes during the next revision of the CPT manual.
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.

The smallest section of the CPT (Current Procedural Terminology) book is typically the "Category II codes," which are optional tracking codes used for performance measurement. These codes provide additional information about the quality of care but do not represent specific procedures or services. In comparison, Category I codes, which describe medical procedures and services, make up the bulk of the CPT book.
Category II codes.
CPT codes, or Current Procedural Terminology codes, typically consist of five digits. These codes are used to describe medical, surgical, and diagnostic services and procedures. There are also some codes that may include additional modifiers, which can provide further specificity about the service rendered.
