What 44310 covers
A surgeon creates an opening from the ileum or jejunum to the abdominal wall, bringing the bowel to the skin to divert intestinal contents. The stoma may be temporary or permanent and may be created during an abdominal operation or as the principal procedure. This code is for a non-tube stoma; it is not the code for placing a feeding or decompression tube into the bowel.
The operative report should identify the small-bowel site, the stoma created, and the indication for diversion. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care through day 90. For multiple procedures in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate for this code. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.
