The medical coding system originated in the 17th century in England to collect statistical data on causes of death. This early system of coding mortality data evolved into the International Classification of Diseases (ICD), which is now in its 10th edition (ICD-10-CM/PCS) and used globally to track health trends and mortality rates. Medical coding translates documentation of a patient's diagnosis, treatment, and services into standardized codes to provide information to payers.
