What 33340 covers

An interventional cardiologist or electrophysiologist advances a catheter through a transseptal route and places an endocardial implant to close the left atrial appendage. The procedure is generally performed in a hospital catheterization or electrophysiology lab with imaging guidance. It is used for selected patients with atrial fibrillation when a strategy to reduce embolic stroke risk is being pursued; the record should identify the indication, implant placement, and procedural findings.

Report 33340 for the transcatheter closure procedure, including its transseptal access and integral fluoroscopic and angiographic guidance. The code has a 0-day global period, so same-day preoperative and postoperative care is included. If other procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate for this anatomy. Assistant-at-surgery payment requires documented medical necessity; co-surgeons are permitted, and team-surgery payment requires supporting documentation.
