CIHI sets the national standard for morbidity data reporting in Canada and maintains, distributes and supports the application of ICD-10-CA (the Canadian modification of ICD-10). CCI is the national standard for classifying health care procedures. Statistics Canada supports the mortality application of ICD-10.

ICD-10-CA (International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Canada) was developed by the World Health Organization (WHO) and enhanced by CIHI to meet Canadian morbidity data needs. ICD-10-CA classifies diseases, injuries and causes of death, as well as external causes of injury and poisoning. It also includes conditions and situations that are not diseases but represent risk factors to health, such as occupational and environmental factors, lifestyle and psychosocial circumstances.

CCI  (Canadian Classification of Health Interventions) was developed by CIHI to accompany ICD-10-CA. It was designed to be service-provider and service-setting neutral and can be used comprehensively throughout Canada’s health systems. CCI classifies a broad range of interventions including therapeutic and diagnostic interventions and other health care interventions, such as assistance with activities of daily living, environmental assessments and counselling.

Other WHO classifications

ICD-11: The WHO is currently developing the 11th revision of the International Classification of Diseases. It is anticipated that ICD-11 will be released by the WHO in June 2018. See Canada’s involvement. 

ICF: The International Classification of Functioning, Disability and Health, developed by the WHO, is a classification of health and health-related domains that describe body functions and structures, activities and participation, and environmental factors.
