CPT code 33933 represents the surgical preparation of a donor heart and lungs received in cold preservation solution for transplantation into a recipient. The code covers intraoperative inspection and repair of cardiac vessels, removal of blood clots, excision of pericardial tissue from the lungs, and trimming of the trachea to the necessary length. This procedure is a critical step in multiorgan thoracic transplantation workflows and has implications for operating room resource use, surgical team coordination, and post-transplant outcomes nationally.

Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical actions captured by the code, typical sites of service, and which payer policies commonly affect coverage and documentation requirements. The publication also summarizes benchmarks and coding guidance relevant to transplant centers, highlights common billing modifiers associated with complex surgical services, and outlines areas where policy updates or payer-specific edits frequently occur.
