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 02R5 includes procedures performed to replace biological or synthetic structures in the atrial septum. These ICD-10-PCS codes are used for inpatient documentation when a portion or all of the atrial septum is surgically removed and replaced with implanted material. Accurate coding within the ICD-10-PCS 02R5 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Atrial Septum Replacement Procedure Overview

Procedures in this group involve replacing all or part of the atrial septum, the wall between the left and right atria of the heart and great vessels system. These replacement procedures implant biological or synthetic material to restore septal structure and function. Accurate coding of atrial septum replacement is important for inpatient reimbursement because it captures the extent of surgical reconstruction and supports correct case mix and payment.

When to Use

Use a code from this group when the atrial septum is intentionally removed or excised and replaced with an implant during the same operative episode. These codes apply when replacement, rather than repair or other interventions, is the principal root operation documented.

Typical Clinical Scenarios

An adult patient with a large secundum atrial septal defect (ASD) causing right heart enlargement and symptomatic exertional dyspnea is admitted electively for open surgical management after percutaneous closure was not feasible due to deficient septal rims. The surgeon excises the deficient portion of the atrial septum and implants a prosthetic patch to restore septal integrity and eliminate left-to-right shunt; inpatient coding captures the replacement of the atrial septum using a synthetic implant via open approach. Typical codes: 02R50JZ
A neonate with a complex congenital atrial septal malformation and associated cardiac anomalies is taken to the operating room during the same admission for percutaneous endoscopic placement of a biologic patch to reconstruct the atrial septum as part of staged corrective surgery. The infant requires inpatient postoperative monitoring in the neonatal intensive care unit for hemodynamic stabilization after replacement of the atrial septal tissue with an autologous or biologic substitute using a percutaneous endoscopic approach. Typical codes: 02R547Z, 02R548Z
An adult with prior surgical closure of an atrial septal defect presents months later with dehiscence of the repair and recurrent significant shunt with right ventricular volume overload; after diagnostic evaluation, the patient undergoes reoperation to excise the failed tissue and replace the atrial septum segment with nonautologous biologic material via open approach to restore septal function. This inpatient revision procedure is coded as replacement of the atrial septum with nonautologous tissue using an open approach. Typical codes: 02R50KZ
