Back to top

Changes/additions to CPT® Category I and Category III codes must meet both general criteria and specific criteria for each code.

General Criteria for Category I and Category III Codes

  • The proposed descriptor is unique, well-defined and describes a procedure or service which is clearly identified and distinguished from existing procedures and services already in CPT.
  • The descriptor structure, guidelines and instructions are consistent with current editorial panel standards for maintenance of the code set.
  • The proposed descriptor for the procedure or service is neither a fragmentation of an existing procedure or service nor currently reportable as a complete service by 1 or more existing codes (with the exclusion of unlisted codes). However, procedures and services frequently performed together may require new or revised codes.
  • The structure and content of the proposed code descriptor accurately reflects the procedure or service as typically performed.  If always or frequently performed with 1 or more other procedures or services, the descriptor structure and content will reflect the typical combination or complete procedure or service.
  • The descriptor for the procedure or service is not proposed as a means to report extraordinary circumstances related to the performance of a procedure or service already described in the CPT code set.
  • The procedure or service satisfies the category-specific criteria set forth below.

  • The procedure or service is performed by many physicians or other qualified health care professionals across the United States.
  • The procedure or service is performed with frequency consistent with the intended clinical use (i.e., a service for a common condition should have high volume).
  • The procedure or service is consistent with current medical practice.
  • The clinical efficacy of the procedure or service is documented in literature that meets the requirements set forth in the CPT code-change application.
