Common Language Description

Extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) are terms that refer to advanced medical procedures designed to provide long-term support for patients experiencing severe heart and lung failure. These procedures involve the use of an artificial lung that oxygenates blood outside the body, allowing it to be circulated back into the bloodstream. The process is critical for patients who cannot maintain adequate oxygenation or perfusion due to various medical conditions. In the context of CPT® Code 33957, the focus is on the repositioning of peripheral arterial and/or venous cannula(e) in pediatric patients, specifically those from birth through 5 years of age. This repositioning is essential to ensure optimal blood flow and oxygenation, as improper placement of the cannula(e) can lead to inadequate support and complications. The procedure includes the use of fluoroscopic guidance, which aids in visualizing the cannula(e) during the repositioning process, ensuring that they are accurately placed for effective ECMO/ECLS support. This code is specifically designated for younger patients, while a different code, CPT® Code 33958, is applicable for patients aged 6 years and older, highlighting the importance of age-specific coding in medical billing and documentation.
