ICD-10-PCS Code For Coronary Artery, Four Or More Arteries: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 02U3 includes procedures performed to supplement coronary artery structures in the heart and great vessels. These ICD-10-PCS codes are used for inpatient documentation when biological or synthetic material is placed on or in coronary arteries to reinforce or augment their function. Accurate coding within the ICD-10-PCS 02U3 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Coronary Artery Supplement Procedure Overview

Procedures in this group involve placing biological or synthetic material to reinforce or augment the function of coronary arteries, targeting the heart and great vessels. These procedures supplement coronary artery structure or function rather than remove or bypass tissue. Accurate coding of these procedures in the inpatient setting ensures the clinical intervention is captured correctly for case mix assignment and reimbursement.

Typical Clinical Scenarios

An elderly patient with progressive multivessel coronary artery aneurysmal degeneration and diffuse atherosclerotic weakening of four or more coronary arteries is admitted for symptomatic ischemia and risk of rupture. The surgical team elects to reinforce the affected coronary segments by applying biologic tissue patches to augment arterial wall integrity during open median sternotomy to stabilize flow and prevent further dilation. Typical codes: 02U307Z, 02U347Z
A middle-aged patient with connective tissue disorder and chronic coronary artery dissection involving four or more coronary branches presents for a planned elective procedure to strengthen the dissections’ weakened arterial walls after medical therapy failed to control recurrent angina. In the inpatient setting a percutaneous endovascular approach is used to place synthetic reinforcement material along the dissected coronary segments to restore vessel stability and improve perfusion. Typical codes: 02U34JZ, 02U33JZ
A patient previously treated with coronary grafting returns with progressive dehiscence and thinning of multiple native coronary arteries (four or more) causing recurrent ischemic events; urgent intervention is required to prevent catastrophic vessel failure. During an emergent percutaneous procedure the team supplements the compromised coronary arteries with nonautologous tissue substitute material to reinforce the vessel walls and address the complication of prior surgery. Typical codes: 02U33KZ, 02U30KZ
