CPT code 33506 represents surgical reimplantation of an anomalous coronary artery from the pulmonary artery to the aorta, typically performed in infants with congenital coronary anomalies to restore coronary blood flow and prevent heart failure. This high-acuity, open cardiac procedure is clinically significant because timely correction can be lifesaving and prevents progressive ventricular dysfunction and congestive heart failure. Nationally, the code is used to classify complex pediatric cardiac surgery encounters and drives inpatient surgical billing, resource allocation, and outcomes tracking.

Key payers referenced in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and the service type represented by CPT code 33506. The publication also covers how the code maps to inpatient surgical workflows, common billing modifiers used with complex cardiac surgery claims, and what benchmarks and policy updates affect coverage and reimbursement for high-complexity pediatric cardiac procedures. The content is intended to inform billing managers, coding professionals, hospital administrators, and clinicians about the clinical intent and billing classification of this procedure, and to provide context for further operational or policy analysis.
