CPT code 33852 defines surgical repair of an incompletely developed or disrupted aortic arch using autogenous graft or prosthetic material performed without cardiopulmonary bypass. This procedure is a specialized cardiovascular surgical intervention typically performed in an inpatient hospital operating room or a dedicated cardiac surgery suite and addresses complex congenital or acquired arch pathology that can be repaired without full cardiopulmonary support. Nationally, accurate coding for high-acuity aortic arch repairs affects clinical reporting, care coordination, and payer reimbursement processes for major cardiovascular centers.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, service setting, and commonly applied modifiers. The publication outlines benchmark considerations for utilization and payment where available, highlights coding clarity for surgical teams and billing staff, and summarizes relevant policy and coverage implications at a national level. Information about associated taxonomies, ICD-10 diagnoses, and related codes is noted where provided; where input data is absent, the text indicates that those specifics are not available.
