Gastrointestinal surgery
About 43870: Surgical gastrostomy tract closure
Reports surgical closure of a gastrostomy opening and tract, commonly when a feeding tube is no longer needed and the site remains patent.
A surgeon closes the gastric opening and gastrostomy tract when enteral access is no longer needed and the site does not seal after tube removal. The service is typically performed in an operating room, including for a persistent gastrocutaneous opening after a feeding gastrostomy has been discontinued. This is definitive surgical closure, not routine removal or exchange of a tube.
Report the procedure when the operative record supports surgical closure of the gastrostomy, rather than continued access or tube maintenance. The day-before preoperative visit and 90 days of related postoperative care are included in the major-surgery global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

43870 billing questions
When is this code appropriate instead of a gastrostomy tube replacement code?
Use 43870 for definitive surgical closure of the gastrostomy opening and tract. Tube replacement codes apply when enteral access is being maintained and the tube is exchanged.
Does this code include routine tube removal?
No. The service is surgical closure of the gastrostomy, not simply taking out a tube; the operative documentation should support closure of the opening and tract.
How does the global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period. Unrelated services are not described by this global-period rule.
Can modifier 50 be used for closure of two gastrostomies?
No. CMS identifies bilateral adjustment as inappropriate for this code. Modifier 50 should not be used.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, while other procedures in the session are subject to the standard multiple-procedure reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation.
What documentation supports co-surgeon billing?
CMS requires supporting documentation for co-surgeons. The record should substantiate the co-surgeons' participation in the surgical service.
