Summary & Overview
CPT 0543T: Transapical Mitral Valve Repair with Artificial Chordae
CPT code 0543T designates a transapical mitral valve repair procedure in which artificial chordae tendineae are placed to correct mitral valve prolapse and reduce mitral regurgitation. As a specialized cardiac surgical technique, this code captures an approach that directly addresses leaflet support by accessing the mitral valve through the apex of the left ventricle. Nationally, accurate reporting of this code matters for procedural tracking, facility resource planning, and payer coverage evaluation for advanced valve-sparing therapies.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical intent of the service, typical sites of care, and the service line context. The publication outlines common modifiers associated with complex surgical services (listed for reference), discusses typical billing and coverage considerations seen with advanced mitral valve repairs, and provides benchmark-oriented insight into how payers and facilities classify and reimburse this specialized procedure.
This summary equips clinicians, coding professionals, and payer policy analysts with the clinical context and billing frame needed to locate CPT code 0543T within cardiothoracic service lines and hospital procedural workflows. Data not available in the input: associated taxonomies, ICD-10 diagnoses, related codes, and payer-specific rate benchmarks.
Billing Code Overview
CPT code 0543T describes a surgical procedure in which the provider approaches the mitral valve through the apex of the left ventricle to place artificial chordae tendineae (fibrous bands) to stabilize the mitral valve and treat mitral valve prolapse and mitral regurgitation. This procedure is a form of mitral valve repair that targets the valve leaflets and supporting apparatus by placing synthetic chordae to restore leaflet coaptation.
-
Service type: Surgical mitral valve repair via transapical (apex of left ventricle) approach involving placement of artificial chordae tendineae
-
Typical site of service: Inpatient or outpatient hospital setting with cardiothoracic surgical capability; performed in an operating room or hybrid cardiac catheterization/operating suite
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with symptomatic degenerative mitral regurgitation presents with exertional dyspnea and intermittent palpitations despite optimal medical therapy. Echocardiography demonstrates posterior leaflet prolapse with severe mitral regurgitation and preserved left ventricular systolic function. The heart team elects a transapical, chordal replacement approach to correct leaflet tethering and restore mitral valve coaptation.
Preoperative workflow includes cardiology evaluation, transthoracic and transesophageal echocardiography to define leaflet pathology, coronary angiography as indicated, and anesthesia assessment. In the operating room or hybrid catheterization lab under general anesthesia, the surgeon gains transapical access through a small left thoracotomy at the cardiac apex, places artificial chordae (e.g., expanded polytetrafluoroethylene sutures) to the prolapsing segment(s), and adjusts chordal length under echocardiographic guidance to eliminate regurgitation. Postprocedure care includes intensive monitoring, postoperative echocardiography to confirm valve competence, anticoagulation management as indicated, and discharge planning with follow-up cardiology and echocardiography surveillance.
