Appendix B in the CPT (Current Procedural Terminology) is significant because it lists annual changes to the CPT coding system. This appendix provides coders with a comprehensive overview of all the modifications made to the codes, which may include additions, deletions, and revisions. Understanding these changes is crucial for ensuring accurate coding and compliance with the latest standards, as it helps medical coders stay up to date with the evolving practices in healthcare.

Being aware of changes listed in Appendix B allows coders to maintain accuracy in billing and documentation, which ultimately impacts claims processing and reimbursement. Therefore, this appendix plays a critical role in the coding process, as well as in facilitating clear communication among healthcare providers and payers regarding the services provided.
