CIHI’s work on classifications helps health care professionals maintain, understand and apply clinical data standards within our health care systems.

At CIHI, we lead the development of a number of classifications to collect, analyze and enhance the consistency and accuracy of information on health care in Canada. We also represent Canada to international agencies working to enhance classification and terminology standards.

CIHI-supported classifications

  • ICD-10-CA — International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Canada: developed by the World Health Organization (WHO) and enhanced by CIHI to meet Canadian morbidity data needs
  • ICD-11 — The World Health Organization (WHO) is currently developing the 11th revision of the ICD
  • ICF — International Classification of Functioning, Disability and Health: developed by WHO to replace ICIDH-2
  • CCI — Canadian Classification of Health Interventions, developed by CIHI to accompany ICD-10-CA: replaces the earlier CCP classification

Make a request for enhancements, additions or changes to ICD-10-CA and/or CCI.
