International Classification of Diseases (ICD) is the international standard diagnostic classification for all general epidemiological, health management purposes and clinical use. These include the analysis of the general health situation of population groups and monitoring of the incidence and prevalence of diseases and other health problems in relation to other variables such as the characteristics and circumstances of the individuals affected, reimbursement, resource allocation, quality and guidelines.
International Classification of Diseases (ICD) provides systematic analysis, interpretation and comparison of morbidity data collected in different areas and at different times. It is a means of classifying medical terms and is defined as a system of categories to which morbid entries are assigned according to established criteria. It is used to support operational and strategic planning, resource utilisation, performance management, reimbursement, research and epidemiology.
The classifications are revised periodically and national information standards and collections requiring International Classification of Diseases (ICD) coding should use the latest mandated version of the International Classification of Diseases (ICD) as given in the table below.
