ICD-10-PCS Code For Ventricular Septum: Procedure Code Group Overview

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

Ventricular Septum Insertion Procedure Overview

Procedures in this group involve the insertion of nonbiological appliances into the ventricular septum of the heart and great vessels to monitor, assist, perform, or prevent a physiological function. These procedures target the heart and great vessels and specifically the ventricular septum as the anatomical site. Accurate ICD-10-PCS coding is important for inpatient reimbursement because it documents the specific insertion procedure performed and supports appropriate case mix assignment and payment.

When to Use

Use a code from this group when a nonbiological device is inserted into the ventricular septum during an inpatient encounter for monitoring or therapeutic cardiac function. Select the code that matches the insertion operation and the ventricular septum body part to ensure accurate documentation and billing.

Typical Clinical Scenarios

An elderly patient presents with symptomatic bradycardia and high-degree atrioventricular block after an acute myocardial infarction, with recurrent syncope despite medical management. During the inpatient admission, a transvenous lead is placed percutaneously into the ventricular septum to provide reliable pacing support and stabilize heart rate. The procedure targets insertion of a pacemaker lead into the ventricular septum to restore and maintain appropriate ventricular pacing. Typical codes: 02HM3JZ
A middle-aged patient with ischemic cardiomyopathy and persistent ventricular dyssynchrony is admitted electively for cardiac resynchronization therapy planning. As part of the device implantation, a ventricular septal lead is placed percutaneously to optimize ventricular pacing and improve synchrony prior to generator placement. This planned, inpatient procedure involves insertion of a cardiac lead into the ventricular septum to assist mechanical coordination of the ventricles. Typical codes: 02HM3MZ
A patient with a previously implanted transvenous defibrillator develops lead malfunction with intermittent failure to sense and capture, prompting inpatient evaluation. During the admission, the malfunctioning lead is replaced with a new defibrillator lead inserted percutaneously into the ventricular septum to reestablish reliable sensing and defibrillation capability. The operative intent is replacement and reestablishment of device therapy by placing a defibrillator lead in the ventricular septum. Typical codes: 02HM3KZ
