Operation Definition

Moving to its normal location, or other suitable location, all or a portion of a body part

Procedure Overview

Reposition procedures move a bursa or, more often, a ligament from an abnormal location back to its correct anatomic position, or to another location that will let it function properly. A common scenario is surgical repositioning of a chronically dislocating patellar or biceps tendon-associated ligamentous structure, or realignment of a displaced ligament following trauma, where the tissue itself is healthy but sitting in the wrong place.

This differs from most other procedures in the family because the ligament or bursa is not cut out, replaced, or reinforced - it is detached, moved, and reattached or otherwise secured in its new position. Surgeons choose this approach when a structural malalignment, rather than tissue damage, is causing pain, instability, or abnormal joint mechanics, such as recurrent shoulder or kneecap dislocation. Restoring normal alignment allows the joint to track and load correctly, reducing repeat injury and improving comfort with movement.

Anatomy & Axis Detail

Upper Extremity Bursa and Ligament, Right

This body part value applies to ligaments and bursae of the right upper extremity that are not separately classified under a specific joint, such as connective tissue along the upper arm or forearm supporting muscle groups and reducing friction during movement. Displacement of these structures from trauma or overuse can alter limb mechanics even without frank tissue disruption, and reposition surgery restores them to correct anatomic alignment without removing or replacing the tissue. Because this designation spans a broad region of the limb rather than a single named joint, it is used when the involved structure does not correspond to one of the more specific shoulder, elbow, wrist, or hand body part values, and documentation should identify the exact anatomic structure whenever possible.

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

This code applies when the operative note describes moving a bursa or ligament to a new site and securing it there, using language such as "transposed," "relocated," or "repositioned." The coder should confirm the structure itself was not resected or supplemented with additional material during the move - only its location changed. A frequent mistake is coding Reposition when a ligament was actually released and reattached at its original insertion point after debridement, which may better reflect Repair. Coders should also verify the correct body part is selected based on the ligament's final anatomic location rather than its origin.

Commonly Confused With

RepairRepair is the operation most likely to be confused here, since both can involve reattaching tissue; the distinction is whether the structure is being fixed in its original position (Repair) or deliberately moved to a different one (Reposition).
ReplacementReplacement should not be selected unless the native ligament is removed and substituted with graft material, which is not the case in a pure repositioning procedure.
ReleaseRelease, found under a different root operation, applies when the goal is simply to free a ligament or bursa from surrounding scar tissue without relocating it.
