ICD-10-PCS Code For Right Atrium: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group X2U9 includes procedures performed to supplement intraluminal devices in the right atrium. These ICD-10-PCS codes are used for inpatient documentation when a biological or synthetic material is placed to reinforce or augment right atrial function via a percutaneous approach. Accurate coding within the ICD-10-PCS X2U9 group is essential for proper inpatient reimbursement, as it captures the specific augmentation procedure performed and supports clinical documentation accuracy.

Right Atrium Supplement Procedure Overview

Procedures in the ICD-10 PCS X2U9 group involve supplementing the right atrium using intraluminal devices to reinforce or augment atrial function within the cardiovascular system. These interventions place a biological or synthetic material into the right atrium via a percutaneous approach and are classified in the New Technology section. Accurate coding of these procedures supports correct inpatient reimbursement and ensures clinical documentation reflects the specific augmentation performed.

267	Endovascular Cardiac Valve Replacement and Supplement Procedures without MCC

Typical Clinical Scenarios

An elderly patient with severe tricuspid regurgitation and symptomatic right-sided heart failure refractory to medical therapy is admitted for planned percutaneous augmentation of the right atrium to improve valve function and reduce regurgitant flow; the intraluminal heterotopic bioprosthetic valve(s) are placed percutaneously to reinforce atrial and valvular competence during a scheduled inpatient procedure. Typical codes: X2U93YA
A middle-aged patient presents acutely with right atrial dilation and progressive hypoxemia after prior transcatheter tricuspid intervention; because of worsening right atrial dysfunction and hemodynamic compromise, a percutaneous heterotopic bioprosthetic valve(s) is implanted in the right atrium to supplement atrial function and stabilize hemodynamics during the inpatient admission. Typical codes: X2U93YA
A patient with prior intracardiac device-related erosion into the right atrium undergoes inpatient revision with placement of an intraluminal heterotopic bioprosthetic valve(s) via a percutaneous approach to reinforce the right atrial structure and restore function after device complication. Typical codes: X2U93YA
