Abdominal surgery
About 49402: Foreign body removal by laparotomy
Reports open surgical removal of a foreign object from the peritoneal cavity, such as a retained item requiring laparotomy.
This service involves surgically entering the abdomen through a laparotomy to locate and remove a foreign object from the peritoneal cavity. A general surgeon or another surgeon experienced in abdominal operations typically performs it in an operating room. A retained surgical item is a recognizable example; the operative report should identify the object and its intraperitoneal location, and describe its removal through the open approach.
Report the code when the documented service is removal of a foreign body from the peritoneal cavity by laparotomy, rather than removal of a specifically coded catheter or shunt. The record should support the target, location, approach, and work performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. For multiple procedures in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

49402 billing questions
When should 49402 be chosen instead of a catheter-removal code?
Use 49402 for open removal of a foreign body from the peritoneal cavity. A tunneled intraperitoneal catheter or a peritoneovenous shunt has a specific removal code, such as 49422 or 49429.
Does the code include the laparotomy?
The service is removal through a laparotomy. The operative documentation should show the open approach and removal; do not treat the laparotomy as a separate exploratory service solely because the abdomen was entered.
What documentation supports reporting 49402?
Document the foreign object, its location in the peritoneal cavity, the laparotomy approach, and the removal performed. A record describing only abdominal exploration without removal does not establish this service.
How does Medicare handle other procedures performed in the same session?
The highest-valued procedure is paid in full, and other procedures are paid at 50%. Modifier 50 is inappropriate for 49402.
Can an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this service. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.
