Colorectal surgery
About 45172: Full-thickness transanal rectal tumor excision
A colorectal surgeon removes a localized rectal tumor through the anus with a full-thickness segment of rectal wall, typically as definitive local treatment.
A colorectal surgeon excises a rectal tumor through the anus, removing the lesion along with the full thickness of the rectal wall at the operative site. This is a local excision rather than removal of the rectum. The service is generally performed in an operating room for a rectal lesion selected for transanal surgical treatment; the excised tissue is available for pathologic examination.
Report this code when the operative note supports a transanal approach and full-thickness removal of the rectal wall, not a superficial or partial-thickness excision. Document the lesion treated and the extent and route of excision. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this single-organ procedure. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery billing is not permitted.

45172 billing questions
How does this differ from 45171?
45172 is for transanal excision that removes the full thickness of the rectal wall. Use 45171 for the transanal tumor excision that does not require full-thickness removal.
Is a transanal biopsy reported with this excision?
A biopsy code describes tissue sampling, while 45172 describes definitive full-thickness tumor excision. The operative documentation should establish whether an excision or only a diagnostic sample was performed.
Can modifier 50 be used for tumors on both sides of the rectum?
No. Modifier 50 is inappropriate for this rectal excision; report the service as a single procedure.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care for the operation.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery billing is not permitted.
What happens when another procedure is performed in the same session?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.
