ICD-10-PCS Code For Coronary Artery, Three Arteries: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0212 includes procedures performed to bypass coronary arteries in the heart and great vessels. These ICD-10-PCS codes are used for inpatient documentation when surgical revascularization is performed for multivessel coronary artery disease involving three coronary arteries. Accurate coding within the ICD-10-PCS 0212 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Coronary Artery, Three Arteries Bypass Procedure Overview

This procedure group includes bypass operations on the coronary arteries and targets the heart and great vessels. Procedures involve creating alternate routes for blood flow around blocked or narrowed coronary arteries supplying the myocardium. Accurate coding of these bypass procedures affects inpatient reimbursement and reflects the complexity and resources used during cardiac surgery.

Typical Clinical Scenarios

A 68-year-old male with unstable angina and ongoing chest pain despite medical therapy is taken urgently to the operating room after coronary angiography demonstrates critical three-vessel coronary artery disease involving the left anterior descending, right coronary, and circumflex arteries. Because multivessel disease requires surgical revascularization, open coronary artery bypass grafting is performed using the left internal mammary artery as the arterial conduit to bypass the three target coronary arteries. The procedure aims to restore myocardial perfusion and stabilize the patient. Typical codes: 02120A9, 02120Z9
A 59-year-old female with progressive exertional angina and positive noninvasive stress testing is scheduled electively for multivessel coronary artery bypass grafting after coronary angiography shows significant stenoses in three coronary arteries. An open procedure is planned using autologous saphenous vein grafts harvested from the leg to bypass each of the three diseased coronary targets to improve long-term symptomatic control and reduce ischemic risk. The operation is performed on an elective inpatient basis under standard cardiopulmonary bypass. Typical codes: 0212093, 02120Z3
A 72-year-old patient with prior single-artery bypass presents with recurrent angina and now has progression to multivessel disease requiring repeat revascularization; the surgeon elects to perform redo open coronary artery bypass targeting three coronary arteries using the right internal mammary artery as the conduit. The operation is undertaken in the inpatient setting because prior graft failure and complex anatomy necessitate open surgical bypass of three coronary vessels to relieve ischemia. Typical codes: 0212098, 02120Z8
