The International Statistical Classification of Diseases and Related Health Problems (commonly known by the abbreviation ICD) is a detailed description of known diseases and injuries. It is published by the World Health Organization and is used world-wide for morbidity and mortality statistics.

It is revised periodically and is currently in its tenth edition, known as the ICD-10.

It was devised to standardize the collection and analysis of mortality statistics. It originally began as the Bertillon Classification (1893) and later became the ICD. Work on ICD-10 began in 1983 and was completed in 1992.

Every disease (or group of related diseases) is described with its diagnosis and given a unique code, up to five letters long.

ICD-CM (Clinical Modification)

A related publication is the ICD-CM (Clinical Modification), published by the U.S. National Center for Health Statistics. It provides for additional morbidity detail. The latest version (2001) of ICD-CM is ICD-9-CM; a draft for ICD-10-CM has been produced.
