CPT code 0545T identifies a transcatheter procedure that inserts an adjustable annulus device across the interatrial septum to reconstruct and tighten a dilated tricuspid valve annulus for treatment of tricuspid regurgitation. As a novel structural heart intervention, this code captures a minimally invasive alternative to open surgical repair for patients with clinically significant tricuspid regurgitation and dilated annulus. Nationally, adoption of transcatheter tricuspid therapies is a growing area of cardiovascular care due to an aging population and increasing recognition of adverse outcomes associated with untreated tricuspid disease.

Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a clinical and billing overview of the procedure, typical sites of service, common modifier usage (for reference), and notes on payer coverage patterns where available. The publication also situates the code in the broader context of structural heart interventions and highlights what to expect in terms of clinical indications and care settings.

This summary serves clinicians, coding professionals, and policy analysts seeking a concise briefing on what CPT code 0545T represents, why it matters for cardiac care delivery, and which major payers are most relevant to coverage and claims discussions. Data not available in the input is noted where applicable.
