CPT code 92924 identifies percutaneous coronary atherectomy, with angioplasty when performed, targeting one major coronary artery and/or one or more branches. This interventional cardiac procedure is used to remove plaque to restore coronary blood flow and may be performed in combination with balloon angioplasty. It is a clinically significant code for cardiovascular specialty billing and hospital service-line reporting because it represents a higher-complexity endovascular revascularization intervention with implications for resource use, facility throughput, and clinical outcomes.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find national benchmarks for utilization and reimbursement patterns across major payers, context on clinical indications and service settings, and notes on coding elements that affect claim adjudication. The publication highlights procedural scope (atherectomy with optional angioplasty in a single major coronary vessel or branches), typical sites of service such as hospital catheterization laboratories or inpatient settings, and common billing modifiers that may appear on claims. Data limitations are noted where input was not provided.

This resource is intended for billing managers, clinical documentation specialists, and policy analysts seeking a concise, nationally oriented briefing on CPT code 92924, its clinical role, and the payer landscape affecting interventional cardiology services.
