What does the term 'brackets' signify in the ICD-10-CM Tabular List?

The term 'brackets' in the ICD-10-CM Tabular List signifies synonyms and alternative terms for codes. When you see brackets around a term, it indicates that the term listed is not part of the formal code description but serves to provide additional context or clarification. This helps coders understand that there may be various terms or phrases that describe the same condition, allowing for more precise coding based on patient documentation. This feature is particularly useful when navigating through complex medical terminology, ensuring that coders are aware of different ways a diagnosis might be expressed.

In contrast, other elements within the Tabular List serve different functions, such as mandatory coding requirements or examples of conditions, which are indicated through different symbols or conventions. Thus, recognizing what brackets represent aids in accurate coding and enhances the coders' ability to maintain compliance with coding standards.
