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

Posterior Tibial Artery, Right

The right posterior tibial artery travels along the deep posterior compartment of the calf, passing behind the medial malleolus to help supply the heel, sole, and plantar structures of the foot. It is a common site for reposition procedures when the vessel has been transected, kinked, or displaced by trauma, tumor resection, or during reconstructive limb surgery, since restoring its normal course is essential for maintaining perfusion to the foot. Its close relationship to the tibial nerve and flexor tendons in the tarsal tunnel means the surgeon must carefully mobilize the artery without injuring these adjacent structures. Because this vessel is a major contributor to foot viability alongside the anterior tibial and peroneal arteries, moving it to a new position while keeping its own blood supply intact is documented distinctly from grafting or occlusion procedures performed on the same segment.

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.

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.
