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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 02C3 includes procedures performed to remove solid matter from coronary arteries in the heart and great vessels. These ICD-10-PCS codes are used for inpatient documentation when extirpation of thrombus, plaque, or other solid material is performed on four or more coronary arteries. Accurate coding within the ICD-10-PCS 02C3 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Coronary Artery, Extirpation Procedure Overview

Procedures in this group involve surgical extirpation of obstructive or unwanted solid matter from the coronary arteries within the heart and great vessels system. These procedures remove thrombus, plaque, or other solid material from four or more coronary arteries to restore or improve coronary blood flow. Accurate ICD-10-PCS coding of these extirpation procedures ensures correct inpatient documentation and supports appropriate case mix assignment and reimbursement.

Typical Clinical Scenarios

An elderly patient presents to the hospital with acute ST-elevation myocardial infarction (STEMI) complicated by large intracoronary thrombus burden involving multiple coronary vessels identified on emergent coronary angiography. The patient is taken to the catheterization lab for urgent mechanical thrombectomy/atherectomy to remove organized thrombus and restore flow in four or more coronary arteries during the same inpatient encounter. Typical codes: 02C33ZZ, 02C33Z7
A middle-aged patient with progressive exertional angina and multivessel coronary artery disease undergoes a planned inpatient hybrid revascularization where catheter-based plaque debulking and extirpation are performed electively on four or more coronary arteries to improve perfusion prior to or instead of bypass grafting. This scheduled procedure uses percutaneous or percutaneous endoscopic atherectomy techniques to remove atherosclerotic plaque from multiple coronary arteries. Typical codes: 02C34ZZ, 02C33Z6
A patient with prior coronary interventions develops recurrent restenosis with organized neointimal tissue and bifurcation involvement in several coronary branches, requiring repeat removal of obstructive solid material during an inpatient revision procedure. The operation targets four or more coronary arteries, including bifurcation sites, using open or percutaneous approaches to extirpate the obstructing tissue. Typical codes: 02C30ZZ, 02C30Z6
