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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 02H0 includes procedures performed to insert nonbiological appliances that monitor, assist, perform, or prevent a physiological function in a coronary artery. These ICD-10-PCS codes are used for inpatient documentation when a device is placed into one coronary artery to provide monitoring or therapeutic support. Accurate coding within the ICD-10-PCS 02H0 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Coronary Artery, One Artery Insertion Procedure Overview

Procedures in this group involve the insertion of a nonbiological appliance into a single coronary artery and target the heart and great vessels. These procedures are performed to monitor, assist, perform, or prevent a physiological function of the coronary circulation without replacing the artery. Accurate ICD-10-PCS coding of these insertion procedures is important for inpatient reimbursement because it captures the specific device placement and supports appropriate case mix and payment.

When to Use

Use a code from this group when an appliance is placed into a single coronary artery during an inpatient encounter for monitoring or therapeutic function. Do not use these codes for procedures that remove or replace the coronary artery or for devices placed in multiple coronary arteries.

Typical Clinical Scenarios

A middle-aged patient is admitted emergently with acute myocardial ischemia and ongoing chest pain after failed medical therapy; coronary angiography identifies a single coronary artery lesion requiring placement of a temporary intraluminal device (such as a sensor or flow-directed catheter) to monitor coronary flow while awaiting definitive intervention. An insertion into one coronary artery is performed during the inpatient stay to provide physiologic monitoring of the affected vessel. Typical codes: 02H03DZ, 02H04DZ
An elective admission for a patient with refractory angina undergoing planned percutaneous placement of a long-term coronary device (for example, an implantable intraluminal pressure or flow monitoring appliance) into one coronary artery to guide medical management and risk stratification. The procedure is performed percutaneously or percutaneous endoscopic approach as part of a scheduled inpatient observation period. Typical codes: 02H03DZ, 02H04DZ
A patient with prior coronary instrumentation presents with device-related malfunction or migration of a previously placed nonbiological coronary appliance confined to a single coronary artery; during the inpatient encounter the malfunctioning device is removed and a replacement nonbiological appliance is inserted into the same artery to restore monitoring or support. The insertion into one coronary artery is documented as part of the revision/replacement procedure. Typical codes: 02H03YZ, 02H04YZ
