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
Hepatic Artery
The hepatic artery, a branch of the celiac trunk supplying oxygenated blood to the liver and biliary tree, has considerable anatomic variability that makes its position clinically significant during hepatobiliary and transplant surgery. Reposition of the hepatic artery involves moving the vessel or its origin to a new site without resecting it, a maneuver used when reconstructing arterial inflow during complex hepatic surgery, correcting an aberrant or replaced hepatic artery encountered incidentally, or reimplanting the vessel after adjacent organ resection. Because the liver depends heavily on hepatic arterial inflow for biliary tree perfusion despite dual portal venous supply, any repositioning requires meticulous technique to avoid kinking or tension that could compromise flow. This procedure is frequently performed in conjunction with other hepatobiliary or transplant-related interventions rather than as an isolated operation.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
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.
