When a patient experiences post-operative bleeding from a Coronary Artery Bypass Grafting (CABG) site and requires resuturing, the most appropriate CPT® code to report is 35820-78.

This code specifically represents a revisional procedure that is performed due to complications arising from the initial surgery, in this case, post-operative bleeding. The -78 modifier indicates that the procedure is an unplanned return to the operating room for a related procedure during the post-operative period. By using this modifier, the medical billing accurately reflects that this procedure was done as a result of complications from the original CABG.

Other codes listed do not specifically represent procedures related to revisional surgery for post-operative complications. Understanding this distinction ensures accurate coding and reimbursement, which is crucial in medical billing and maintaining proper documentation of patient care.
