CPT code 33602 covers surgical repair of aortic or pulmonary semilunar valve insufficiency, using sutures or a patch to correct regurgitation and restore valve competence. This intervention aims to prevent progressive ventricular dilation and loss of cardiac function caused by backward blood flow. Nationally, semilunar valve repair influences surgical quality metrics, perioperative resource use, and long-term cardiac outcomes, making accurate coding and clinical documentation important for case identification and performance measurement.

Key payers commonly involved in coverage and payment for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, common settings where the service is delivered, and what typical documentation should communicate to support the code. The publication also summarizes how this code fits into cardiac surgical service lines and what operational stakeholders should expect in terms of inpatient surgical workflow and resource implications.

This summary is intended for national audiences, including coding professionals, hospital administrators, and clinical teams, to provide a clear description of the procedure represented by CPT code 33602, its clinical rationale, and the payer landscape addressed in the companion sections.
