Which coding convention is indicated by supplementary words enclosed in parentheses?

The concept of supplementary words enclosed in parentheses is that they serve as clarifications or details that enhance the understanding of the code but do not influence which code should be assigned. These words are typically guidelines that provide context or additional information, yet they do not change the fundamental meaning or selection of the primary code. Therefore, they do not impact the final coding decision, making it clear that their role is supportive rather than directive in the coding process.

Recognizing this convention is important as it helps coders avoid confusion and misinterpretation when reviewing diagnoses or procedural codes, ensuring more accurate and effective coding practices. The presence of these supplementary terms should not distract from identifying the main condition being coded, which is why they are considered to have no effect on the coding itself.
