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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 02H4 includes procedures performed to insert nonbiological appliances that monitor, assist, perform, or prevent physiological functions in the coronary vein. These ICD-10-PCS codes are used for inpatient documentation when a device is placed percutaneously and endoscopically into the coronary vein for monitoring or therapeutic assistance. Accurate coding within the ICD-10-PCS 02H4 group is essential for proper inpatient reimbursement, as it captures the specific insertion procedure performed and supports clinical documentation accuracy.

Coronary Vein Insertion Procedure Overview

This procedure group includes percutaneous endoscopic insertion procedures that place nonbiological appliances into the coronary vein. These procedures target the heart and great vessels to monitor, assist, perform, or prevent physiological functions without replacing a body part. Accurate coding of these insertion procedures supports correct inpatient documentation and influences reimbursement by reflecting the specific device and approach used. Precise assignment in the International Classification of Diseases, Tenth Revision, Procedure Coding System is essential for case mix and payment integrity.

When to Use

Use a code from this group when a device is placed into the coronary vein via a percutaneous endoscopic approach for monitoring or therapeutic assistance. These codes apply only when the insertion is performed in an inpatient setting and the procedure record documents the coronary vein as the body part.

Typical Clinical Scenarios

An elderly patient with symptomatic bradycardia and syncope is admitted for implantation of a coronary sinus lead as part of a left ventricular pacing system to treat heart block and improve cardiac output. The procedure is performed percutaneously and endoscopically to place a pacemaker lead into the coronary vein for pacing support. Coding reflects insertion of a pacemaker lead into the coronary vein via the correct approach. Typical codes: 02H44JZ
A middle-aged patient presents emergently with refractory ventricular arrhythmias despite medical therapy and is taken to the electrophysiology lab for percutaneous endoscopic placement of a defibrillator lead into the coronary vein as part of a transvenous implantable cardioverter-defibrillator system. The goal is to provide defibrillation capability and adjunctive pacing via a lead positioned in the coronary venous system. Coding should capture insertion of a defibrillator lead into the coronary vein using the percutaneous endoscopic approach. Typical codes: 02H44KZ
A patient with an existing transvenous cardiac device is admitted for revision because a previously placed coronary vein lead has fractured and is malfunctioning; the team performs percutaneous endoscopic removal of the fractured lead and places a new cardiac lead into the coronary vein to restore device function. Documentation supports coding for insertion of a cardiac lead into the coronary vein via the percutaneous endoscopic approach during the revision procedure. Typical codes: 02H44MZ
