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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 02C5 includes procedures performed to remove solid matter from the atrial septum in the heart and great vessels. These ICD-10-PCS codes are used for inpatient documentation when surgical or percutaneous removal of obstructive tissue or thrombus from the atrial septum is performed. Accurate coding within the ICD-10-PCS 02C5 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Atrial Septum Extirpation Procedure Overview

Procedures in this group involve the extirpation, or taking out, of solid matter from the atrial septum within the heart and great vessels body system. These procedures remove obstructive tissue, thrombus, or other solid material from the atrial septum to restore normal intracardiac function. Accurate ICD-10-PCS coding of these extirpation procedures supports correct inpatient reimbursement and reflects the clinical resources used during the hospital stay.

When to Use

Use codes from this group when an inpatient procedure involves surgical or catheter-based removal of solid matter from the atrial septum. Do not use these codes for lesion removal in other cardiac structures or for nonextirpation interventions.

Typical Clinical Scenarios

An elderly patient on anticoagulation presents emergently with acute right-sided heart failure signs and hypoxia after prolonged atrial fibrillation; transesophageal echocardiography reveals a large organized thrombus adhered to the atrial septum causing obstruction of atrial flow. The patient is admitted for urgent removal of the septal thrombus to restore hemodynamics and reduce embolic risk; an open surgical approach via median sternotomy may be required if percutaneous extraction is not feasible. Typical codes: 02C50ZZ, 02C53ZZ
A middle-aged patient with a chronic iatrogenic septal device complication develops symptomatic atrial inflow obstruction and recurrent transient ischemic attacks despite medical therapy; imaging shows obstructive fibrous tissue growth at the atrial septum around the device. The patient is scheduled for an elective inpatient procedure to remove the obstructive tissue from the atrial septum, often performed via a percutaneous endoscopic technique when anatomy allows to minimize invasiveness. Typical codes: 02C54ZZ
A postoperative cardiac surgery patient in the ICU develops a localized infected nidus of organized material on the atrial septum identified on imaging and suspected source of persistent sepsis; conservative measures fail and source control is required. The patient is taken back to the operating room for extirpation of the infected material from the atrial septum using an open approach to ensure complete removal and decontamination. Typical codes: 02C50ZZ
