The International Classification of Diseases is a system of categories for classifying various forms of morbidity (departure from healthiness or well-being). The ICD is designed to facilitate the statistical study of disease phenomena; hence, it is based on a number of considerations–cause of the morbidity, site of affliction, circumstances of onset and course of the affliction, and quality of information in medical reports. Currently, the “Tenth revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10)” published in 1992 and “International Classification of Diseases for Oncology, Third Edition” published in 2000 by the World Health Organization (WHO), are in use at RERF.
