Definition:

The 9th version of the ICD (International Classification of Disease) coding system (with Clinical Modifications), developed by the World Health Organization (WHO) that is used to classify diseases, health conditions and procedures. This version was used extensively in Canadian hospitals for recording diagnoses and procedures in hospital discharge abstracts.

ICD-9-CM is divided into 17 chapters. Individual codes are at least three digits, up to a maximum of five digits, depending on the specificity required. For the majority of codes, numeric values are used. Two additional categories include E-codes (external cause of injury) and V-codes (supplemental classification of factors influencing health).

As of April 1, 2004, Manitoba hospitals replaced ICD-9-CM with ICD-10-CA for coding diagnoses and the Canadian Classification of Health Interventions (CCI) for coding procedures/interventions.
