Summary & Overview
CPT 92937: Percutaneous Revascularization of Coronary Bypass Graft
CPT code 92937 denotes percutaneous revascularization performed through or within a coronary artery bypass graft, typically involving angioplasty, atherectomy, and/or stent placement in a single major coronary artery or its branches. This code captures a high-acuity interventional cardiology service used to restore myocardial blood flow when native vessels or grafts are obstructed, and it is relevant to hospitals, catheterization laboratories, and payers managing costs and quality for acute coronary syndromes and graft failure. Key payers in national analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context and applicability, common payer coverage considerations, typical sites of service, and benchmarking content where available. The publication summarizes procedural scope, billing relevance for single-graft revascularization, and how the code fits within interventional cardiology service lines. Data not available in the input is noted where applicable, and the document focuses on operational and coding clarity rather than clinical recommendations.
Billing Code Overview
CPT code 92937 describes percutaneous (through-the-skin) catheter-based revascularization performed on a coronary artery bypass graft. The provider advances a catheter into a surgically created bypass graft and performs one or more interventions such as angioplasty, atherectomy, and/or stent placement to restore blood flow to heart muscle. This procedure applies to revascularization of a single major coronary artery and/or its branches through or within the bypass graft.

Service type: Percutaneous coronary revascularization of bypass graft

Clinical & Coding Specifications
Clinical Context
A 68-year-old male with prior coronary artery bypass grafting (CABG) 10 years earlier presents with recurrent exertional angina and a positive stress test. Coronary angiography demonstrates significant stenosis within a saphenous vein graft supplying the right coronary distribution. After diagnostic catheterization confirms a flow-limiting lesion in the bypass graft, the interventional cardiologist performs percutaneous transcatheter access of the graft and proceeds with revascularization (angioplasty and drug-eluting stent placement) to restore myocardial perfusion.
The clinical workflow includes pre-procedure evaluation (history, medication reconciliation, labs, and informed consent), vascular access (typically femoral or radial), selective catheterization of the bypass graft, intraprocedural imaging and hemodynamic monitoring, performance of angioplasty and/or atherectomy and stent deployment as indicated, post-procedure hemostasis and monitoring in a recovery area or cardiac observation unit, and discharge planning with antiplatelet therapy and follow-up. Typical site of service is an inpatient cardiac catheterization laboratory or an outpatient ambulatory catheterization center depending on patient stability and comorbidities.
