About 44820: Mesenteric lesion excision
Reports surgical removal of a lesion arising in the mesentery, such as a mesenteric cyst or tumor, rather than a lesion of the bowel itself.
This service involves surgically removing a lesion located in the mesentery, the tissue that supports and carries vessels to the intestines. Typical targets include a mesenteric cyst or tumor. A general or colorectal surgeon may perform the operation during abdominal surgery in a hospital or other surgical facility. The operative report should identify the lesion’s mesenteric location and describe its removal, including any related bowel work.
Select this code when the removed lesion arises in the mesentery; a lesion of a bowel pouch or the bowel wall points to a different service. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. 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 50% multiple-procedure reduction. Modifier 50 is inappropriate for this anatomy. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

44820 billing questions
How is this distinguished from excision of a bowel pouch?
Use this code when the lesion arises in the mesentery. A Meckel diverticulum is a bowel pouch, so its excision is a different service.
Does this code include removal of bowel?
The target here is a mesenteric lesion. If the operation also removes a segment of bowel, the operative report should describe that work separately for coding review.
Should modifier 50 be appended for a lesion on both sides?
No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this anatomy.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be allowed. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
