Reasoning around moving to CCI and our subset of it

This article explains our choice of Canadian Classification of Interventions (CCI) as a procedure coding schema and of the subset of codes we include.

Why are we moving to a new procedure coding schema?

Our old diagnosis list was made in-house designed mostly for the Critical Care setting where our database started out. In that data set we combined diagnoses and procedures.
A serious limitation of the current/old system is that it did not distinguish procedures from diagnoses. For example, CABG was considered as a diagnosis, when it's actually a procedure done for a diagnosis of Coronary artery disease, chronic (atherosclerosis, chronic ischemic heart disease).

Going along with the diagnosis coding in ICD10, the Canadian national standard usrd by CIHI for coding of procedures of all types is Canadian Classification of Interventions (CCI)

We have made a number of adaptations so we don't need to use all 18,000 codes.
Small and common procedures can be so frequent that collecting all would have significantly increased collection efforts.
It's OK to exclude these because if something important comes of them, it will be reflected in the ICD10 collection.
For a listing of procedures that we have consciously chosen not to code, see CCI procedures we don't code.
