Which CPT appendix contains additions, deletions, and revisions?

The correct choice is the appendix that provides a comprehensive list of changes made to the Current Procedural Terminology (CPT) code set for the given year. This appendix is invaluable for coders and healthcare professionals who need to stay up-to-date with modifications in coding practices, including new codes that have been added, old codes that have been deleted, and any revisions to existing codes.

Appendix B is specifically designated for this purpose, ensuring that users have readily accessible information about changes to the coding system, which is important for ensuring accurate coding and billing.

While there are other appendices within the CPT manual that serve different functions—such as providing modifiers, definitions, and guidelines—none offer the consolidated list of annual changes like Appendix B does. This focus on updates reinforces correct coding practices and helps avoid potential errors related to outdated codes or guidelines.
