Summary & Overview
CPT 33514: Coronary Artery Bypass Grafting with Five Vein Grafts
CPT code 33514 denotes a multivessel coronary artery bypass graft (CABG) procedure using five vein grafts to restore coronary circulation. This open-heart surgical revascularization is a high-acuity procedure with significant implications for patient outcomes, hospital resource use, and national surgical volume. Because CABG remains a common intervention for advanced coronary artery disease, accurate coding of procedures such as 33514 matters for clinical documentation, quality measurement, and payment.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines how payers typically classify and reimburse complex CABG procedures and highlights benchmarking elements relevant to hospitals and cardiothoracic surgery programs.
Readers will find: an overview of the clinical context for five-graft CABG, typical sites of service and care pathways, common modifiers and coding considerations (Data not available in the input) as a reference note, and what to expect from payer coverage patterns and national payment frameworks. The piece is intended to help coding professionals, compliance staff, and health system leaders understand the procedural scope of 33514, where it fits in surgical service lines, and the broader administrative context for billing and reporting at a national level.
Billing Code Overview
CPT code 33514 describes a coronary artery bypass graft (CABG) procedure in which the provider grafts five vein segments from another part of the body, commonly the leg, to bypass damaged coronary vessels. The procedure diverts blood flow around obstructed or diseased coronary arteries to restore circulation, improve cardiac function, and reduce symptoms such as angina.
Service type: Surgical revascularization (multivessel coronary artery bypass grafting)
Typical site of service: Inpatient hospital setting, operating room with cardiothoracic surgical team
Clinical & Coding Specifications
Clinical Context
A typical patient is a 65-year-old male with progressive exertional angina and ischemic changes on noninvasive testing despite optimal medical therapy. Coronary angiography demonstrates multi-vessel coronary artery disease with high-grade stenosis of the left anterior descending, circumflex, and right coronary artery branches unsuitable for percutaneous coronary intervention. The cardiothoracic surgical team schedules an elective coronary artery bypass grafting (CABG) using five vein grafts harvested from the greater saphenous vein to bypass diseased coronary vessels.
Preoperative workflow includes cardiology assessment, pre-anesthesia evaluation, informed consent, and perioperative optimization of comorbidities (e.g., diabetes, hypertension). Intraoperative care involves general endotracheal anesthesia, median sternotomy, cardiopulmonary bypass or off-pump technique as indicated, harvesting of vein conduits, construction of five distal coronary anastomoses and proximal grafting to the aorta, hemostasis, and chest closure. Postoperative workflow includes intensive care unit monitoring, hemodynamic support, pain control, wound care for both chest and leg harvest sites, early mobilization, sternal precautions education, cardiac rehabilitation referral, and discharge planning with secondary prevention therapy.
