Details
ICD-10 is an international disease classification system published by the WHO. It assigns unique codes to diseases, injuries, and causes of death, utilized globally for mortality statistics, hospital records, and insurance claims. Crucially, it is a classification system designed for administrative and statistical 'counting,' rather than precise clinical documentation. In the US context, the base ICD-10 has been extended into two nationally managed variants: ICD-10-CM (for diagnosis coding) and ICD-10-PCS (for procedure coding). When integrating with technical standards like FHIR, the ICD-10-CM system is frequently referenced. Its primary purpose is to provide a common language that allows for the comparison of disease incidence and mortality rates across different countries and over time, supporting global public health surveillance and policy making.
