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 02WM includes procedures performed to correct or revise devices or device positions in the ventricular septum. These ICD-10-PCS codes are used for inpatient documentation when a portion of a malfunctioning cardiac device or a displaced device affecting the ventricular septum must be corrected or repositioned. Accurate coding within the ICD-10-PCS 02WM group is essential for proper inpatient reimbursement, as it captures the specific revision procedure performed and supports clinical documentation accuracy.

Ventricular Septum Revision Procedure Overview

Procedures in the ICD-10-PCS ICD-10 PCS 02WM group involve revision of the ventricular septum within the heart and great vessels system to correct or adjust a portion of a malfunctioning device or the position of a displaced device. These interventions target the ventricular septum and may include repairing device-related issues or correcting adjacent structural concerns. Accurate coding of these revisions supports appropriate inpatient payment and reflects the specific clinical work performed. Proper selection of codes ensures documentation aligns with the operative intent and findings.

When to Use

Use a code from this group when an inpatient revision procedure is performed to correct or reposition a device component involving the ventricular septum. Assign codes that best match the operative action and documented findings for the ventricular septum revision.

Typical Clinical Scenarios

An adult patient with a previously implanted synthetic patch in the ventricular septum presents electively for evaluation of progressive left-to-right shunting documented on echocardiography and persistent heart failure symptoms. Cardiac imaging demonstrates partial dehiscence of the synthetic substitute at the septal repair site without active infection, and the surgical team plans an open revision to resecure or replace the synthetic material and restore septal integrity. An open approach revision is performed to directly visualize and correct the malfunctioning synthetic substitute on the ventricular septum. Typical codes: 02WM0JZ
A middle-aged patient in the catheterization lab develops worsening hypoxia and evidence of a displaced septal occluder device with residual shunt after percutaneous closure of a ventricular septal defect. Because the device position is unstable but can be accessed endoscopically percutaneously, the team elects a percutaneous endoscopic revision to reposition or adjust the portion of the device affecting the ventricular septum. The goal is to correct the displaced device component without open thoracotomy. Typical codes: 02WM4JZ
An elderly patient previously treated with a synthetic ventricular septal substitute develops device-related erosion with localized thrombosis and recurrent arrhythmia; there is no gross infection but the device portion requires surgical intervention due to mechanical complication. During inpatient admission for symptomatic arrhythmia and risk of embolization, the operative team performs an open revision of the synthetic substitute on the ventricular septum to correct the malfunctioning device portion and address associated septal disruption. Typical codes: 02WM0JZ
