Operation Definition

Moving to its normal location, or other suitable location, all or a portion of a body part

Procedure Overview

Reposition procedures move a gastrointestinal structure to its normal anatomic location, or to another location that allows it to function properly, without cutting away or replacing any tissue. The classic example is surgical correction of malrotation in infants, where the small and large intestines are rearranged into a more typical configuration, but the category also covers reduction of a volvulus, correction of intestinal intussusception when done surgically rather than by enema, and repositioning a prolapsed rectum back into normal alignment.

These procedures address structures that are anatomically present and viable but sitting in the wrong place, whether from a congenital anomaly, a twist that developed over time, or a mechanical shift such as organ prolapse. Because the tissue itself is not removed or substituted, the surgery is fundamentally about untwisting, realigning, or fixing the organ in a corrected position, sometimes with sutures anchoring it there.

Anatomy & Axis Detail

Ascending Colon

Repositioning the ascending colon corrects malrotation, volvulus, or displacement of this normally retroperitoneal, fixed segment that runs from the cecum to the hepatic flexure. Because the ascending colon is ordinarily anchored along the right paracolic gutter, its involvement in a repositioning procedure usually reflects abnormal mobility from incomplete fixation, prior surgery, or a mesenteric defect allowing the segment to twist or herniate. The surgeon reduces the abnormal position, taking care to preserve the ileocolic and right colic vascular arcades running along its mesenteric border, then may mobilize and re-fix the bowel along the lateral peritoneal reflection. Because this segment lies near the duodenum and right kidney, repositioning can also relieve compression of these adjacent structures when the colon has shifted out of its normal retroperitoneal groove.

Approach: External

External approach applies to procedures performed directly on the skin or mucous membrane, or on an accessible body surface, without any instrumentation passing through a puncture or orifice. It covers things like manual reduction of a fracture or excision of a skin lesion. It differs from Via Natural or Artificial Opening in that no internal passage is entered at all, only the exposed surface.

Coding & Documentation

Assigning this code requires documentation that the organ was moved to a new or corrected position, distinct from documentation describing repair of a tear or removal of tissue. Operative notes for volvulus reduction or rectal prolapse correction should describe the maneuver used to untwist or realign the bowel and any fixation performed to hold it in place. A recurring coding error is applying Reposition when the procedure actually removed a segment of nonviable bowel after derotation, which instead requires Resection to be coded for that portion. Coders should also watch for cases where repositioning is performed alongside repair of an associated defect, both of which may need to be captured separately.

Commonly Confused With

RepairReposition is easily confused with Repair, since both can appear in the same operative note when a twisted segment is untwisted and then a resulting tear is sutured; only the movement of the organ itself is Reposition.
ResectionIt also differs from Resection, which is used when nonviable or diseased bowel is removed rather than relocated, and from Restriction, which narrows a passage rather than repositioning it.
