Valve and Thoracic Coding: Repair vs. Replacement, Open vs. VATS
Beyond bypass, cardiothoracic coding divides cleanly into valve work and general thoracic resections — each with its own selection logic.
Valves: which valve, and repair vs. replace
- Aortic: replacement 33405 (prosthetic), 33406 (allograft), 33410 (stentless)
- Mitral: repair 33425–33427 vs. replacement 33430
- Transcatheter aortic (TAVR): 33361–33369 by access route
A valve procedure and CABG at the same session are separately reportable. TAVR frequently involves two surgeons — apply co-surgeon (-62) rules per payer policy, with each surgeon documenting distinct work.
Thoracic: extent and approach
Lobectomy is 32480 open vs. 32663 VATS; wedge resection 32505 open vs. 32666 VATS; segmentectomy has its own codes. Diagnostic mediastinoscopy or thoracoscopy performed as part of a same-session definitive resection bundles into the resection. Chest tubes placed as part of the thoracic procedure are included.
Clinical Capture distinguishes repair from replacement and open from VATS directly from the operative description, and keeps bundled diagnostic scopes off the claim.
This article is educational and not coding, billing, or legal advice. Always verify codes and values against the current CPT®, ICD-10-CM, and CMS Physician Fee Schedule, follow NCCI edits and payer policy, and confirm with a certified coder before submitting a claim. Document only work that was actually performed.
