CPT® Code 49428

The procedure described by CPT® Code 49428 involves the ligation of a peritoneal-venous shunt, which is a medical intervention aimed at managing ascites, a condition characterized by the accumulation of fluid within the peritoneal cavity. A peritoneal-venous shunt is a device that facilitates the drainage of excess fluid from the abdominal cavity into the venous system, thereby alleviating the symptoms associated with ascites. During the ligation process, the physician performs a surgical procedure to tie off the shunt, effectively stopping its function. This is typically done when the shunt is no longer needed or if complications arise. The procedure requires careful dissection of the shunt tubing, which is located beneath the skin and subcutaneous tissue of the chest wall. The ligation is accomplished by placing a ligature around the tubing, ensuring that the flow of fluid is halted. This procedure is crucial for patients who may be experiencing adverse effects from the shunt or who have resolved the underlying condition that necessitated its placement.
