Category 2 contains performance measurement tracking codes in an alphanumeric identifier with a letter in the last field. (EX: 4246C)
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.
Category III codes
yes
The category number or level codes that represent services and procedures that have been approved by the FDA and proven to have clinical effectiveness are typically found in category 1 codes. Category 1 codes are used for procedures, services, and tests that have been well-established through clinical research and have a demonstrated clinical effectiveness. These codes are widely accepted by insurance companies and healthcare providers.
unlisted codes
General Recommendation codes are most common.
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).
When no fifth-digit subcategory codes are in that category
Category 1 contains procedures and/or services identified by 5 digit codes.
