Unroofing of Anomalous Coronary Artery
A patient with an anomalous origin of the right coronary artery was discovered to have significant coronary artery disease and presented for coronary artery bypass graft (CABG) with unroofing of the intramural segment of the anomalous right coronary artery. Following completion of the CABG, attention was turned to the ascending aorta. The tissue surrounding the aortic root was dissected and the right coronary artery was identified as it emanated from the right sinus of Valsalva. The intramural segment was unroofed with scissors and the intima was approximated on the media and adventitia, improving the ostium of the right coronary artery. What is the ICD-10-PCS code for unroofing the anomalous right coronary artery? ...

Article Overview
This premium article explains how a coronary anomaly case is approached from a procedure-coding perspective, with emphasis on ICD-10-PCS assignment for a surgical release/unroofing procedure performed in the setting of coronary artery bypass grafting. It is intended for coders, CDI specialists, and revenue cycle staff who work with cardiovascular operative reports and need to understand how the case is classified. The article focuses on the operative scenario, the relevant ICD-10-PCS selection considerations, and the final procedure coding outcome.
Why This Topic Matters
Cardiovascular operative reports often include multiple procedures and anatomy-specific terminology that can affect code assignment. Understanding how this unroofing case is classified helps support accurate inpatient procedure coding and consistent abstraction of complex cardiac surgery documentation.
