Summary & Overview
CPT 33922: Pulmonary Artery Transection/Incision with Cardiopulmonary Bypass
CPT code 33922 represents a specialized cardiothoracic surgical procedure in which the pulmonary artery is transected or incised to address an underlying pulmonary artery anomaly, performed with cardiopulmonary bypass. This code identifies a high-acuity, operative intervention typically delivered in an inpatient hospital operating room or tertiary surgical center and is significant for surgical service classification, resource allocation, and payer reimbursement pathways nationally. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn the clinical context and service setting for the procedure, the primary payer landscape considered in national analyses, and what types of benchmarks and policy updates are relevant to such high-complexity cardiothoracic services. The publication covers typical utilization patterns, expected site-of-service implications for hospital billing, and policy considerations affecting coverage and payment for complex cardiac surgical procedures. Data on modifiers, associated taxonomies, ICD-10 diagnoses, specific payer policies, and detailed reimbursement benchmarks are not provided in the input and therefore are not included here.
Billing Code Overview
CPT code 33922 describes a surgical procedure in which the provider transects or incises across the pulmonary artery to correct an underlying anomaly of the pulmonary artery. The procedure is performed with cardiopulmonary bypass.
Service type: Invasive cardiothoracic surgery (pulmonary artery transection/incision) with cardiopulmonary bypass
Typical site of service: Inpatient hospital operating room or tertiary care cardiothoracic surgical center
Clinical & Coding Specifications
Clinical Context
A realistic patient scenario involves a pediatric or adult patient with a congenital or acquired pulmonary artery anomaly such as an anomalous origin, significant pulmonary artery stenosis associated with complex congenital heart disease, or a traumatic/iatrogenic injury requiring direct surgical transection or incision of the pulmonary artery with reconstruction. The patient typically presents with symptoms of right ventricular outflow obstruction, hypoxemia, progressive heart failure, or hemodynamic instability. Preoperative evaluation includes transthoracic and transesophageal echocardiography, chest CT or cardiac MRI to delineate pulmonary artery anatomy, cardiac catheterization for hemodynamic assessment when indicated, and multidisciplinary planning with cardiothoracic surgery, pediatric or adult congenital cardiology, anesthesiology, and perfusion. The procedure is performed in an operating room with cardiopulmonary bypass support; intraoperative monitoring includes transesophageal echocardiography and invasive arterial and central venous pressure monitoring. Postoperative care involves pediatric or cardiac intensive care unit monitoring, ventilatory support as needed, inotropic management, anticoagulation per institutional protocol, and imaging follow-up to assess repair integrity and pulmonary blood flow.
