CPT code 0544T represents a novel percutaneous transseptal procedure to implant an adjustable annulus device for reconstruction and tightening of a dilated mitral valve annulus to treat mitral regurgitation. As structural heart interventions expand, this code captures a device-based, minimally invasive alternative to open surgical annuloplasty and is relevant for cardiac specialists, payers, and hospitals considering coverage, site-of-service planning, and coding guidance.

Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines clinical context for the procedure, typical settings where it is performed, and common billing considerations. Readers will find national-level benchmarks where available, summaries of payer coverage considerations, and a concise review of the clinical purpose and procedural intent for CPT code 0544T.

This summary is intended to inform coding teams, revenue cycle managers, and clinical program leads about the code’s purpose and where it fits within structural heart service lines. Data not available in the input is noted where applicable in detailed sections that follow.
