Summary & Overview
CPT 33788: Pulmonary Artery Repair and Reimplantation
CPT code 33788 covers surgical repair and reimplantation of a pulmonary artery with an existing defect, often used to correct anomalous pulmonary artery origin. This operative procedure is clinically significant for congenital and structural heart disease specialists because it addresses anatomical defects that can impair pulmonary circulation and long-term cardiopulmonary function. Nationwide, surgical management of pulmonary artery anomalies carries implications for resource use in tertiary care centers and for coverage decisions by major payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the procedure, the typical inpatient hospital setting, and the service type as cardiothoracic surgical repair. The publication summarizes common billing modifiers and highlights areas where policy updates or coding clarification may affect claim submission and adjudication. It also outlines benchmark considerations and coding relationships relevant to surgeons, hospital billing teams, and payers.
This summary is intended to inform clinical coders, billing professionals, and policy analysts about the procedural intent and expected site of service for CPT code 33788, and to guide further review of payer-specific coverage rules and payment policies.
Billing Code Overview
CPT code 33788 describes surgical repair and reimplantation of a pulmonary artery with an existing defect. The procedure is commonly performed to correct an anomalous or abnormal origin of the pulmonary artery, restoring normal pulmonary arterial anatomy and blood flow.
Service Type: Cardiothoracic surgical repair
Typical Site of Service: Inpatient hospital operating room
Clinical & Coding Specifications
Clinical Context
A typical patient is an infant or child with congenital malformation of the pulmonary artery such as anomalous origin of a pulmonary artery branch (for example anomalous origin of the right pulmonary artery from the ascending aorta) who presents with differential pulmonary blood flow, respiratory distress, or failure to thrive. The surgical team (pediatric cardiothoracic surgeon, anesthesiology, perfusionists as needed) evaluates imaging (echocardiography, cardiac MRI or CT angiography, and cardiac catheterization when indicated) to plan reimplantation of the affected pulmonary artery to the main pulmonary artery. The clinical workflow includes preoperative assessment and optimization, intraoperative median sternotomy or thoracotomy with mobilization of the anomalous vessel, repair and reimplantation of the pulmonary artery (33788) with any patch augmentation if required, intraoperative hemodynamic monitoring and possible cardiopulmonary bypass, immediate postoperative intensive care unit monitoring for respiratory and hemodynamic stability, and follow-up imaging to confirm vessel patency and right ventricular function. Typical site of service is an inpatient hospital operating room with postoperative care in a pediatric cardiac intensive care unit. Common payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
