Canadian Classification of Health Interventions 

The Canadian Classification of Health Interventions (CCI) is the national standard for classifying health care procedures. CCI is the companion classification system to ICD-10-CA. CCI replaces the Canadian Classification of Diagnostic, Therapeutic and Surgical Procedures (CCP) and the intervention portion of ICD-9-CM in Canada.

Scope of CCI

CCI classifies a broad range of interventions, such as

  • Therapeutic interventions including inpatient and day surgeries, surgical and non-surgical
  • Diagnostic interventions including diagnostic imaging, tests, measurements, biopsies and explorations
  • Cognitive, psychosocial and sensory therapeutic interventions
  • Other health care interventions such as assistance with activities of daily living, environmental assessments and counselling
  • Therapeutic interventions strengthening the immune system

For more information, see the overview of CCI sections and code ranges.

Benefits of CCI

CCI specifies more precisely than ever before the interventions and services health professionals provide. It has been designed to be service-provider and service-setting neutral and can be used comprehensively throughout health systems. A comparison of CCI with CCP and ICD-9-CM illustrates many of the improvements over its predecessor classifications. Other benefits of CCI include

  • Canadian control over the classification
  • Improved scope and content
  • Enhanced structure and presentation
  • Responsiveness to user needs

CCI coding structure

CCI replaces CCP and/or ICD-9-CM as the standard for the classification of health-related interventions in Canada; information systems that collect and store procedure codes must be modified to accommodate the CCI coding structure.
