CPT code 33365 represents a transcatheter aortic valve replacement (TAVR/TAVI) performed specifically via a transaortic approach. This procedure involves delivering and deploying a replacement aortic valve through the lumen of a catheter introduced directly through the aorta. Nationally, TAVR is a high-acuity, resource-intensive structural heart intervention with growing clinical and policy attention because of its role in treating aortic valve disease in diverse risk populations.

Key payers addressed in related billing analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise view of clinical context for CPT code 33365, typical sites of service, common billing modifiers (listed separately), and what to expect in payer coverage patterns and billing benchmarks at a national level. The publication also summarizes coding relationships and areas where policy updates or payer-specific edits commonly affect claims for transcatheter aortic valve procedures.

This summary provides clinicians, coding professionals, and payer analysts an executive snapshot of the procedure code, its clinical setting, and the scope of issues that influence reimbursement and utilization reporting for transaortic TAVR services.
