Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 33957 covers

This service covers percutaneous adjustment of peripheral cannula position in a venovenous extracorporeal membrane oxygenation or extracorporeal life support circuit. It may be needed when a cannula is malpositioned or its position interferes with effective circuit flow. Cardiothoracic or vascular surgeons and other clinicians experienced in ECMO cannulation may perform the procedure in an operating room, catheterization laboratory, or intensive care setting. The service concerns repositioning an existing peripheral cannula, not placing or removing one.

Select the code when the documented procedure is percutaneous repositioning for venovenous support; the record should identify the cannula site, the reason for adjustment, and the technique performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
