Coronary Artery Bypass Graft Utilizing Internal Mammary as Pedicle Graft
Our facility is unclear regarding the coding of coronary artery bypass grafting (CABG) using the left internal mammary artery (LIMA). We are specifically debating whether the LIMA is considered a free graft or a pedicle graft, and if harvesting of the LIMA is also coded. If the LIMA graft remains attached, would only the bypass be coded with 6th character “Z” for no device? ...

Article Overview
This Find-A-Code article addresses a coronary artery bypass grafting scenario involving the internal mammary artery as a pedicle graft. It is aimed at coders and clinical documentation reviewers who need to understand how the procedure is represented in ICD-10-PCS and whether related harvesting is separately captured. The article focuses on a specific documentation example and the coding interpretation associated with it.
Why This Topic Matters
CABG procedure coding can vary depending on how the conduit is documented, so accurate interpretation affects code selection and procedure reporting. This topic is especially relevant for inpatient coding professionals, CDI specialists, and staff working with cardiovascular operative reports and ICD-10-PCS.
