What 49418 covers

This code covers percutaneous placement of a tunneled catheter through the abdominal wall into the peritoneal cavity. It provides ongoing peritoneal access, commonly for drainage of recurrent ascites, including malignant ascites. Interventional radiologists often perform the procedure; surgeons may also place the catheter. The catheter is tunneled, but this service does not include placement of a subcutaneous port.

Select the code when the record supports a new catheter placed percutaneously and tunneled into the peritoneal cavity. Document the indication, access route, tunneling, and final catheter position; distinguish a catheter with a port or an exchange of an existing catheter. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires medical-necessity documentation; co-surgeons and team surgery are not permitted.
