ICD-10-PCS Code For Chordae Tendineae: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 02R9 includes procedures performed to replace chordae tendineae in the heart and great vessels. These ICD-10-PCS codes are used for inpatient documentation when surgical replacement of the chordae tendineae is performed to restore or substitute the function of damaged or diseased chordae. Accurate coding within the ICD-10-PCS 02R9 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Chordae Tendineae Replacement Procedure Overview

Procedures in this group involve surgically replacing the chordae tendineae within the heart and great vessels, a component of the cardiac apparatus that helps maintain valve leaflet function. These operations are classified in the Medical and Surgical section of the International Classification of Diseases, 10th Revision, Procedure Coding System and target the heart and great vessels. Accurate coding of chordae tendineae replacement is important for inpatient reimbursement because it documents the specific replacement operation and supports appropriate case mix and payment.

Typical Clinical Scenarios

An elderly patient with chronic ischemic mitral regurgitation develops progressive heart failure symptoms and echocardiography shows ruptured or severely elongated mitral valve chordae leading to flail leaflet and severe regurgitation; the patient is admitted for elective surgical valve intervention to restore leaflet support and improve valve competence, requiring removal and replacement of diseased chordae with biologic or synthetic substitutes during open cardiac surgery. Typical codes: 02R907Z, 02R90JZ
A middle-aged patient presents emergently after infective endocarditis has damaged the subvalvular apparatus of the mitral valve, causing acute severe regurgitation and hemodynamic instability; during urgent open-heart surgery to control infection and restore valve function, the destroyed chordae are excised and replaced with nonautologous or autologous tissue substitutes. Typical codes: 02R908Z, 02R90KZ
A patient with prior minimally invasive transcatheter mitral repair develops recurrent symptomatic regurgitation from degeneration of previously implanted artificial chordae; during a planned percutaneous endoscopic reintervention to revise the subvalvular apparatus, replacement chordae are placed using percutaneous endoscopic techniques with synthetic or tissue substitutes. Typical codes: 02R94JZ, 02R947Z
