What kind of codes does the ICD-10-CM system primarily focus on?

The ICD-10-CM system is specifically designed to capture and classify diagnoses related to diseases, injuries, and health conditions. It serves as a coding system used by healthcare providers to document patient diagnoses in a standardized manner. This coding system allows for the effective communication of patient information concerning diagnoses among healthcare providers, insurers, and health organizations.

Unlike procedure codes, which are intended to describe the services and operations performed on patients, or service codes that may involve specific treatments or encounters, ICD-10-CM highlights the significance of classifying and understanding various health conditions. Similarly, device codes, which would detail medical devices used in treatment, are not under the purview of ICD-10-CM, which is strictly focused on the diagnoses. Thus, the emphasis on diagnosis codes encapsulates the primary function of ICD-10-CM in the healthcare system.
