Procedure Overview
Reposition procedures on the heart and great vessels move a structure back to where it belongs, or to a location that works better, without cutting it out or replacing it. The clearest example is correcting a great vessel that formed or drifted out of its normal position, such as moving a malpositioned aorta or pulmonary artery during repair of a congenital heart defect. Surgeons also reposition the heart itself in rare cases of displacement within the chest.
These operations matter because the heart and great vessels only work when blood flows through them in the right sequence and direction. A vessel that arises from the wrong chamber, or a heart that has rotated or shifted, can cause the circulation to short-circuit or starve tissue of oxygen. Repositioning restores the anatomic relationships needed for normal blood flow, often as part of a larger congenital repair rather than a standalone fix.
Most patients encountering this term are looking at operative notes from pediatric cardiac surgery, since congenital malpositions are the most common reason this root operation applies here.
Anatomy & Axis Detail
Coronary Artery, Two Arteries
Reposition of two coronary arteries is most often performed during the arterial switch operation for transposition of the great arteries, in which both coronary arteries must be carefully excised from the native aortic root and reimplanted into the neoaorta to preserve myocardial blood supply. This step is considered one of the most technically critical parts of the operation, since coronary artery patterns vary considerably between patients and anomalous origins or intramural courses increase surgical difficulty. Because both vessels are moved in the same operative session, this body part value captures the combined procedure rather than two separate single-artery codes. Documentation should confirm that both coronary ostia were transferred, distinguishing this from cases where only one artery required repositioning.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Coding & Documentation
A coder assigns Reposition only when the documentation describes moving a body part to a new site while leaving it in place otherwise, not cutting it free and reattaching it elsewhere as a graft or transplant. The operative note needs to state that the vessel or cardiac structure was mobilized and relocated, ideally naming the anatomic origin and destination.
The most common mistake is confusing Reposition with Transfer, which moves a part while keeping its own blood supply to serve a new function, or with the corrective steps of a Great Vessel Transposition repair, where multiple root operations often apply to different parts of the same procedure and each needs to be coded separately based on what actually happened to that specific structure.
