CPT® Code 49426

The CPT® Code 49426 refers to the procedure known as the revision of a peritoneal-venous shunt. This medical intervention is performed by a physician to address issues related to an existing peritoneal-venous shunt, which is a device used primarily for the management of ascites, a condition characterized by the accumulation of fluid in the peritoneal cavity. The peritoneal-venous shunt facilitates the drainage of excess fluid from the peritoneal cavity into the venous system, thereby alleviating the symptoms associated with ascites. The procedure involves either repositioning or replacing components of the shunt, depending on the specific malfunction. This may include adjustments to the peritoneal shunt itself, the valve that regulates fluid flow, or the venous catheter that connects to the bloodstream. The revision process is critical to ensure the continued effectiveness of the shunt in managing fluid levels and preventing complications associated with ascites.
