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 02Q2 includes procedures performed to repair coronary artery structures in the heart and great vessels. These ICD-10-PCS codes are used for inpatient documentation when surgical repair of three coronary arteries is performed to restore patency, correct defects, or reestablish normal coronary anatomy and function. Accurate coding within the ICD-10-PCS 02Q2 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Coronary Artery, Three Arteries Repair Procedure Overview

This procedure group includes repair operations on the coronary arteries of the heart and great vessels, specifically addressing three coronary arteries. Procedures restore, to the extent possible, the normal anatomic structure and function of the coronary arteries. Accurate ICD-10-PCS coding of these repair procedures supports appropriate inpatient reimbursement and reflects the complexity of care provided.

Typical Clinical Scenarios

An elderly patient presents to the emergency department with acute onset severe chest pain, hemodynamic instability, and ECG changes consistent with an extensive anterior and lateral myocardial infarction involving multiple coronary territories. Coronary angiography reveals traumatic dissection and rupture of three separate coronary artery segments requiring urgent surgical repair to restore coronary continuity and perfusion; an open operative approach is used given the need for direct vessel repair. Typical codes: 02Q20ZZ
A middle-aged patient with progressive angina despite medical therapy is electively scheduled for surgical repair after preoperative imaging shows complex multivessel coronary artery aneurysmal dilation and localized defects in three coronary arteries that are amenable to direct repair. The planned inpatient procedure uses a percutaneous approach to access and repair the coronary arterial defects without a full open chest operation to restore normal vessel anatomy and flow. Typical codes: 02Q23ZZ
A patient who previously underwent coronary intervention develops symptomatic recurrent ischemia from iatrogenic coronary artery injury involving three arteries identified on follow-up studies; because the injuries are focal and accessible, a minimally invasive percutaneous endoscopic repair is performed during the same hospitalization to correct the structural damage and reestablish patency. Typical codes: 02Q24ZZ
