About 33418: Percutaneous transcatheter mitral valve repair
Reports catheter-based repair of mitral regurgitation using an initial prosthesis, including transseptal access when performed, during a structural heart procedure.
This code covers a catheter-based mitral valve repair, commonly a transcatheter edge-to-edge procedure for mitral regurgitation. A structural heart team, typically including an interventional cardiologist and cardiac surgeon, performs it in a hospital catheterization laboratory or hybrid operating room. The catheter is advanced to the mitral valve, often through transseptal access, and a prosthesis is used to improve leaflet coaptation. The code includes the transseptal puncture when performed.
Report 33418 for the initial prosthesis; report 33419 for each additional prosthesis. The operative report should support the percutaneous approach, mitral valve repair, and prosthesis use. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
