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 02T9 includes procedures performed to resect chordae tendineae in the heart and great vessels. These ICD-10-PCS codes are used for inpatient documentation when a surgeon removes all or part of the chordae tendineae as the operative treatment. Accurate coding within the ICD-10-PCS 02T9 group is essential for proper inpatient reimbursement, as it captures the specific resection procedure performed and supports clinical documentation accuracy.

Chordae Tendineae Resection Procedure Overview

This procedure group includes resections of the chordae tendineae, the fibrous cords within the heart that anchor the atrioventricular valves to the papillary muscles. These operations are performed on the heart and great vessels system to remove all or part of the chordae tendineae. Accurate ICD-10-PCS coding of these resections ensures inpatient documentation reflects the operative treatment and supports appropriate hospital reimbursement.

When to Use

Use a code from this group when the operative report documents resection of the chordae tendineae during an inpatient procedure. Do not use these codes if the chordae tendineae are repaired, left intact, or replaced with a prosthetic structure.

Typical Clinical Scenarios

An elderly patient presents acutely with severe mitral regurgitation after papillary muscle rupture from a recent myocardial infarction, causing pulmonary edema and hemodynamic instability; the patient is taken to the operating room for urgent removal of disrupted chordae tendineae that are contributing to valve dysfunction and heart failure. A resection procedure is performed to remove the damaged chordae as part of the emergent operative management. Typical codes: 02T90ZZ
A middle-aged patient with chronic degenerative mitral valve disease undergoes a planned inpatient valve surgery because elongated, fibrotic chordae are causing progressive symptomatic mitral regurgitation despite medical therapy; during the elective operation the surgeon resects portions of the chordae tendineae to restore leaflet coaptation. This elective reparative strategy involves cutting out diseased chordae to improve valve function. Typical codes: 02T90ZZ, 02T94ZZ
A patient who previously had a transcatheter mitral valve intervention develops recurrent symptomatic regurgitation due to entanglement or obstruction from residual chordal tissue; during a subsequent percutaneous procedure the interventional team removes obstructing chordae under imaging guidance to relieve valve obstruction and symptoms. The targeted removal of chordae is performed percutaneously to address the complication of prior valve therapy. Typical codes: 02T93ZZ
