CPT code 93591 represents the percutaneous insertion of the first occlusion device to close a leak around the aortic valve. This structural heart intervention addresses paravalvular or transvalvular leaks around a prosthetic or native aortic valve and is increasingly relevant as transcatheter valve therapies expand. The code captures a specialized interventional cardiology procedure that typically occurs in a hospital catheterization laboratory or interventional suite and has implications for procedural coding, device coverage, and bundled payment considerations nationally.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and coding definitions, plus what to expect in payer coverage and reimbursement benchmarking. The publication outlines common claims and billing considerations tied to device-based aortic leak closure and summarizes policy developments influencing payment pathways and prior authorization practices.

This resource helps coding professionals, revenue cycle leaders, and clinical program managers understand where CPT code 93591 fits within structural heart service lines, typical sites of service, and payer engagement priorities. Data not available in the input is noted where applicable.
