Which appendix of the CPT contains annual coding changes?

The appendix that contains annual coding changes is Appendix B of the CPT (Current Procedural Terminology). This appendix specifically outlines the changes made to the coding regulations and guidelines each year, allowing coders to stay updated on modifications, deletions, and additions to code descriptions and instructions. This is particularly important in the medical coding field, as the healthcare landscape is continuously evolving, requiring coders to adapt to maintain accuracy in billing and compliance.

Other appendices serve different purposes: Appendix A lists modifiers, Appendix C includes the codes for unlisted services, and Appendix D provides a summary of the add-on codes. Each appendix is designed to provide valuable information relevant to code use, but only Appendix B focuses specifically on the annual revisions and updates necessary for effective and compliant coding practices.
