What symbols indicate the beginning and end of text changes in a description?

The correct choice is indicated by right and left triangles. In the context of coding and medical terminology, the use of these specific symbols is to signify revisions or modifications within a code description. These triangles mark the beginning and end of any changes, such as additions or deletions, that have been made to the text.

The right and left triangles are visually distinct and easy to identify, allowing coders to quickly spot relevant updates within a long list of procedures or terms. This clarity helps ensure accurate coding and keeps professionals informed about the most current definitions and updates to procedures. Understanding symbols used in coding descriptions is crucial, as it aids in maintaining the accuracy and integrity of medical billing and documentation processes.
