CPT® Code 49436

The CPT® Code 49436 refers to the delayed creation of an exit site from an embedded subcutaneous segment of an intraperitoneal cannula or catheter. This procedure is typically performed after an initial surgical intervention where a portion of the cannula or catheter is placed subcutaneously, starting from the peritoneal cavity. The embedded segment is designed to facilitate the delivery of fluids or medications directly into the peritoneal space, which is the area within the abdomen that houses various organs. The external portion of the cannula or catheter is then threaded through the abdominal wall, ultimately exiting at a remote site, often located in the chest area. This technique is crucial for patients requiring long-term access for therapies such as peritoneal dialysis or other intraperitoneal treatments, ensuring that the cannula remains secure and minimizes the risk of infection or dislodgment.
