ICD-10 Chapter XX: External causes of morbidity and mortality
ICD-10 is an international statistical classification used in health care and related industries.

Produced by the World Health Organization, it is used in several countries around the world. Some have gone on to develop their own national enhancements, building off the international classification.

Chapter XX of ICD-10 captures external causes of morbidity and mortality. Codes from Chapter XX are not intended to be used in isolation; instead they are for use with codes from Chapters I to XIX.
