The International Classification of Diseases, Tenth Revision (ICD-10) was developed and is maintained by the World Health Organization (WHO). The U.S. National Center for Health Statistics (NCHS) is the WHO Collaborating Center for the Family of International Classifications in North America, and is the U.S. governmental agency responsible for overseeing ICD use in the U.S.

ICD-10 is used to promote international comparability in the collection, processing, classification, and presentation of mortality statistics from death certificates.

ICD-10 consists of:

  • tabular lists containing cause-of-death titles and codes;
  • inclusion and exclusion terms for cause-of-death titles;
  • an alphabetical index to diseases and nature of injury, external causes of injury, table of drugs and chemicals; and
  • description, guidelines, and coding rules.

ICD-10 is used in a variety of clinical and health care applications for reporting, morbidity statistics, and billing.

ICD-10 is updated annually in January.
