What does a "section" in the ICD-10-CM manual refer to?

In the ICD-10-CM manual, a "section" refers to a collection of codes that are grouped based on similar conditions or anatomical sites. This organization helps clinicians and coders easily locate and categorize relevant codes for diagnoses. Each section is designed to encompass a specific category of disease or injury, facilitating a systematic approach to coding that reflects clinical practice.

The structure of the ICD-10-CM is hierarchical, with sections typically serving as a higher-level organization that leads to more specific subcategories and individual codes. By grouping codes this way, the manual allows for clearer communication of patient diagnoses and aids in data analysis and reporting.

This classification enhances the ability to identify trends, manage resources, and ultimately improve patient care by ensuring accurate and consistent coding practices across various healthcare settings.
