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 02H2 includes procedures performed to insert nonbiological appliances that monitor, assist, perform, or prevent a physiological function in the coronary arteries of the heart. These ICD-10-PCS codes are used for inpatient documentation when a device is placed in three coronary arteries to provide monitoring, assist with blood flow, or otherwise support cardiac physiological function. Accurate coding within the ICD-10-PCS 02H2 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Heart And Great Vessels Insertion Procedure Overview

This procedure group encompasses insertion of a nonbiological appliance that monitors, assists, performs, or prevents a physiological function for the coronary arteries supplying the heart. These procedures target the heart and great vessels system, specifically involving three coronary arteries. Accurate ICD-10-PCS coding is important for inpatient reimbursement because it captures the exact insertion procedure performed and supports correct clinical documentation and case mix assignment.

When to Use

Use a code from this group when a device is placed into three coronary arteries during an inpatient admission to provide monitoring or assist cardiac function. These codes apply when the procedure involves insertion of a nonbiological appliance rather than replacement or removal of an anatomical structure.

Typical Clinical Scenarios

An elderly patient with multivessel ischemic cardiomyopathy presents with exertional angina refractory to medical therapy; coronary angiography demonstrates severe stenoses in the left anterior descending, right coronary, and circumflex arteries. During a planned inpatient coronary intervention, nonbiological appliances are inserted into all three coronary arteries to improve perfusion and assist coronary flow as part of a staged revascularization strategy. Typical codes: 02H23DZ, 02H24DZ
A middle-aged patient is admitted urgently with an acute ST-elevation myocardial infarction involving multiple coronary territories and is taken to the cath lab for emergent invasive management; angiography reveals critical lesions in three major coronary arteries requiring placement of adjunctive intraluminal devices to stabilize flow. Because the procedure is performed percutaneously in the inpatient setting to monitor and assist coronary circulation during acute ischemia, codes reflecting percutaneous insertion into three coronary arteries are appropriate. Typical codes: 02H23DZ, 02H23YZ
A patient with prior coronary interventions develops recurrent ischemia and angiographic evidence of stent-related complications across three coronary vessels; during a scheduled inpatient corrective procedure, surgeons perform open insertion of nonbiological appliances into each of the three affected coronary arteries to address flow impairment and provide longer-term assistive support. This revision scenario involves open insertion into three coronary arteries and should be coded to the open approach entries in the group. Typical codes: 02H20DZ, 02H20YZ
