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.
