About 44650: Repair of Internal Intestinal Fistula
Reports operative repair of an intestinal fistula, with code selection guided by the fistula’s anatomy and the specific work documented in the operative report.
CPT 44650 describes operative repair of an abnormal tract involving intestine and another bowel segment or an adjacent structure. A general or colorectal surgeon typically performs the repair in a hospital operating room, identifying the tract and repairing the involved bowel opening or openings. The operative report should establish the fistula’s origin and destination and describe the repair performed.
Select the code based on the documented anatomy and procedure, not merely the diagnosis of a fistula. Use the more specific fistula codes when the connection is between bowel and skin or bowel and bladder. The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this service.

44650 billing questions
When should 44650 be chosen over 44640?
Use 44650 for an intestinal fistula that is not an enterocutaneous fistula. When the tract connects bowel to skin, 44640 is the more specific code.
How does 44650 differ from 44660 or 44661?
For an enterovesical fistula, use the specific bowel-to-bladder code: 44660 when repair is without intestinal or bladder resection, or 44661 when resection is performed.
What documentation supports 44650?
Document the fistula’s origin and destination, the bowel segments or adjacent structures involved, and the operative steps used to repair it. Include any resection performed.
Can modifier 50 be appended?
No. Modifier 50 is inappropriate for this intestinal fistula repair.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
