Moving to its normal location, or other suitable location, all or a portion of a body part
Procedure Overview
Reposition procedures move a respiratory structure to its correct anatomic location without cutting any of it away or adding replacement material. The classic example in this body system is diaphragmatic plication, where a surgeon folds and sutures an abnormally high, flaccid diaphragm, often caused by phrenic nerve injury, back down into its normal position to improve breathing mechanics. Correcting a displaced or twisted lung lobe (torsion) after surgery also belongs here.
These procedures are chosen when the underlying tissue is intact and functional but sitting in the wrong place, as opposed to situations where tissue must be removed or reconstructed. The goal is purely mechanical realignment so the structure can do its normal job again.
Anatomy & Axis Detail
Lower Lung Lobe, Left
The left lower lung lobe occupies the posterior and inferior portion of the left thoracic cavity below the oblique fissure, supplied by segmental bronchi serving the superior and basal regions adjacent to the diaphragm and descending aorta. Reposition applies when this lobe is surgically relocated to restore normal anatomic position, most often in repair of a left diaphragmatic hernia, where lower lobe tissue has passed through a diaphragmatic defect into the abdomen, or in correction of lobar torsion compromising the bronchovascular pedicle. Its close anatomic relationship to the descending thoracic aorta requires careful dissection during repositioning, and operative documentation should specify that the lobe was returned to or realigned within its normal thoracic location rather than partially excised.
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
Coders need documentation that the surgeon relocated an existing body part to a normal or otherwise suitable position, distinct from simply repairing a hole or defect in place. For diaphragm cases, the note should describe plication or folding to reduce an eventration, not just suturing a tear. A common error is coding diaphragm plication as Repair because both involve suturing, when the defining action is repositioning redundant tissue rather than closing a defect.
