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

Peroneal Artery, Left

The left peroneal artery lies deep within the posterior leg compartment along the fibula, supplying the lateral muscles and forming important collateral connections to the tibial arteries at the ankle. This vessel frequently retains flow when the tibial arteries are diseased or occluded, so repositioning it is often part of limb-preserving vascular procedures where the artery must be relocated to reestablish a viable path, such as after fibular fracture repair or vascular trauma. Because it runs close to the fibula and the flexor hallucis longus, dissection requires careful attention to avoid injuring adjacent musculoskeletal structures during mobilization. Coding this as a reposition reflects that the vessel is moved to a different position with its native blood supply preserved, distinct from procedures that excise, replace, or bypass the segment.

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.

Commonly Confused With

TransferTransfer, used elsewhere in ICD-10-PCS for moving tissue while keeping its vascular supply intact, is conceptually similar but does not apply to arteries functioning as the primary body part being moved for their own sake.
BypassBypass can resemble Reposition when a vessel's flow path is altered, but Bypass creates a new conduit or route rather than physically relocating the native artery, which is the defining feature of Reposition.
