How are new additions and revitions indicated in your cpt code book each year?

New additions and revisions in the CPT code book are indicated through specific symbols. A bullet (•) denotes a new code, while a triangle (▲) indicates a code that has been revised or changed. Additionally, a horizontal triangle (▴) signifies that a code has been deleted. Each annual edition of the CPT code book includes a summary of these changes for easy reference.
