Operation Definition
Moving to its normal location, or other suitable location, all or a portion of a body part
Procedure Overview
Reposition procedures move an artery, or a segment of one, to a different location or restore it to its proper anatomic position without removing tissue or adding replacement material. In the lower extremities and pelvis this is an uncommon but important root operation, most often encountered when an artery has been displaced by trauma, congenital anomaly, or a prior surgical dissection and needs to be moved to a location where it functions correctly or does not interfere with another planned procedure.
Examples include transposing a renal or iliac artery during complex aortic reconstruction, or relocating a vessel during organ transplantation to create adequate inflow to a transplanted kidney. The vessel itself is not resected or replaced; it is detached at one end and reattached in a new position or orientation.
Anatomy & Axis Detail
Renal Artery, Right
The right renal artery runs from the aorta behind the inferior vena cava to the renal hilum, and its relatively long, deep course makes it a candidate for transposition when its origin or path causes functional compromise, such as in nutcracker-type compression or during complex aortic reconstruction. Reposition here means the vessel is freed and moved to a different location or reattached at a new site on the aorta or a bypass graft, restoring an unobstructed angle of entry into the kidney. This differs from bypass or replacement because no substitute conduit is placed and no portion of the artery is removed; the native vessel itself is relocated. Coders should confirm from the operative note that the artery was physically repositioned rather than simply dissected free or stented in place.
Approach: Percutaneous
Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.
Coding & Documentation
Coders need operative documentation that clearly states the artery was moved to a new location, not simply exposed, clamped, or repaired in place, since Reposition requires an actual change in anatomic position. The note should specify the originating and destination location of the vessel, which affects the body part value selected.
A frequent mistake is coding a transposition performed as part of a larger transplant or bypass procedure as a separate Reposition when it is actually an integral, non-separately-reportable step of the main procedure. Coders also sometimes confuse temporary retraction or mobilization of a vessel during exposure, which is not coded at all, with true Reposition, which requires a permanent relocation.
