Chapters in ICD-10-CM classify diseases according to which besides body systems?

The classification of diseases in the ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) is based on various criteria, one of which is etiology. In this context, etiology refers to the cause or origin of a disease, such as whether it is infectious, genetic, or environmental. The ICD-10-CM chapters are arranged not only according to body systems but also by the underlying cause of diseases, which helps in understanding the nature of the conditions being classified.

For example, diseases that share a common etiology can often exhibit similar clinical presentations and treatment modalities, making it pragmatic to group them together in the classification system. This organization allows healthcare providers and researchers to better analyze health trends and allocate resources effectively in public health and clinical settings.

The other options, while related to the medical field, do not accurately capture the additional classification criteria used in the ICD-10-CM. Anatomy primarily relates to the structure of body systems but does not encompass the broad scope of disease causation. Specialty pertains more to the areas of medical practice and is not a classification criterion within the ICD-10-CM system. Procedure refers to the interventions performed and is distinct from the classification of diseases themselves, as ICD-10
