What does the ICD-10-CM code book typically use to indicate specific coding situations?

The ICD-10-CM code book employs brackets and italics as conventions to indicate specific coding situations. Brackets are typically used to enclose synonyms, alternative wording, or explanatory phrases within the code descriptions. This helps coders understand that the terms included within the brackets may not be required for the code but can provide additional context. Italics are used to highlight certain terms, such as the titles of specific conditions or diseases, emphasizing the primary focus for that coding section.

These formatting choices are crucial for accurate coding, as they guide coders in selecting the appropriate codes based on the clinical scenario and documentation provided. Understanding how these elements function within the code structure enhances a coder’s ability to ensure compliance and accuracy in healthcare billing and reporting practices.
