Last Updated: 2020-05-21


    This concept provides a summary of how Coronary Artery Bypass Surgery have been defined in MCHP research and administrative data. This includes information about the identification and coding of Coronary Artery Bypass Surgery, as well as a brief summary of how it has been used in MCHP research.

Definition, Measurment and Coding

    Bypass surgery is performed on patients with significant narrowing or blockage of coronary arteries to replace the narrowed and blocked segments, which permits an increase in blood flow to deliver oxygen and nutrients to the heart muscles.

    The rate of coronary artery bypass graft (CABG) surgery is measured by the number of bypass surgeries performed on residents aged 40 and older per 1,000 residents age 40 and older. Bypass surgery is defined by ICD-9-CM procedure codes 36.10-36.14 and 36.19 or a CCI code 1.IJ.76 in any procedure field in an inpatient hospital abstract . These procedures are performed only at the two tertiary hospitals (Health Sciences Centre and St. Boniface General Hospital) in Manitoba; out-of-hospital interventions were excluded.
