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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

49418 billing questions

How is this code distinguished from 49419?

49418 describes percutaneous placement of a tunneled intraperitoneal catheter without a port. Use 49419 when the placement includes a subcutaneous port.

Is this the code for an open peritoneal dialysis catheter placement?

No. 49421 describes open insertion of a tunneled intraperitoneal catheter for dialysis; 49418 is for percutaneous placement.

Can catheter imaging or guidance be billed separately?

The submitted facts do not specify separate reporting for imaging or guidance. The record should clearly support the percutaneous catheter placement and its final position.

Can modifier 50 be used for bilateral placement?

No. CMS identifies bilateral adjustment as inappropriate for this code.

What documentation supports reporting 49418 rather than an exchange code?

Document that a new tunneled catheter was placed percutaneously, including the indication, route, and final position. An exchange of an existing drainage catheter is a different service.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
