Abdominal surgery
About 49425: Peritoneovenous shunt insertion
Reports surgical placement of a peritoneovenous shunt to move ascitic fluid from the abdominal cavity into the venous circulation.
This service places a shunt connecting the peritoneal cavity with the venous system, allowing ascitic fluid to flow into the circulation. It is generally performed by a surgeon in a hospital operating room for a patient with ascites when peritoneovenous diversion is selected. The operative record should identify the indication and document creation of the abdominal-to-venous shunt pathway and its placement.
Report 49425 for the shunt insertion itself, not for later revision, evaluation, ligation, or removal. Documentation should distinguish new placement from work on an existing shunt. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

49425 billing questions
When should 49425 be chosen instead of 49426?
Use 49425 for placement of a new peritoneovenous shunt. Code 49426 describes revision of an existing abdominal-venous shunt.
Does 49425 cover later shunt removal?
No. The insertion service is distinct from removal of an existing shunt, reported with 49429.
How does 49425 differ from tunneled intraperitoneal catheter placement?
A peritoneovenous shunt routes peritoneal fluid into the venous circulation. Code 49418 is for insertion of a tunneled intraperitoneal catheter, not a peritoneovenous shunt.
What documentation supports reporting 49425?
Document the indication, that a new peritoneovenous shunt was placed, and the operative details establishing the shunt connection. The record should make clear that the service was not revision or removal of an existing shunt.
How are other procedures in the same session paid?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures in that session are paid at 50%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation.
