Navigate CPT Appendix S: AI taxonomy for medical services, procedures

Why This Topic Matters

As AI-enabled services become more common, coding teams need a shared framework for recognizing how these services are categorized in CPT and where new technology-based procedures may be placed. Understanding the taxonomy supports consistency, awareness of current guidance, and better alignment with evolving medical coding workflows.
