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 tendon, or a portion of one, from its usual anatomic location to a different, often more favorable, position while keeping the tendon otherwise intact. Tendon transfer surgery is the most familiar example, where a functioning tendon is detached from its original insertion and reattached elsewhere to restore movement lost to nerve injury, muscle imbalance, or paralysis, such as transferring a wrist tendon to substitute for a paralyzed finger extensor.

These procedures are also used to correct tendons that have slipped out of their normal groove or track, such as a dislocating peroneal tendon at the ankle, where the tendon is surgically returned to and stabilized within its proper anatomic channel. The underlying goal is always to change the tendon's position or course, not to repair damage to the tendon tissue itself, though repair of associated damage may be documented in the same operative session.

Anatomy & Axis Detail

Trunk Tendon, Left

On the left trunk wall, tendinous insertions of muscles like latissimus dorsi and the abdominal wall extensions attach broadly across ribs and fascia, contributing to trunk rotation and stabilization. Repositioning a left trunk tendon relocates this attachment surgically, commonly performed when restoring shoulder girdle or spinal function after nerve palsy, or when correcting a congenital or post-traumatic deformity affecting trunk symmetry. The procedure differs from simple repair in that the tendon's insertion point is deliberately changed to redirect its mechanical pull, often to substitute for a nonfunctional muscle elsewhere. Given the trunk's layered musculature, precise identification of which tendon is moved, and confirmation that the tendon itself remains in the body, is essential for accurate procedural documentation.

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 should look for clear language describing detachment from one anatomic location and reattachment or rerouting to another, distinguishing this from procedures that merely repair a tendon in its native position. The documentation should specify both the origin and destination of the moved tendon segment, since body part values are assigned based on the tendon's location, and transfers can span values if the tendon moves between defined body regions.

A frequent error is confusing tendon transfer with muscle transfer coding when a musculotendinous unit is moved, since the correct body system and root operation depend on whether the objective and documentation center on the tendon or the muscle component. Coders should also avoid double-coding a repair of tendon fraying at the transfer site as a separate procedure when it is an inherent part of the reposition itself.

Commonly Confused With

RepairReposition is most often confused with Repair, since a transferred tendon is also sutured into its new location; the key distinction is that Repair restores a tendon to its own original site, while Reposition intentionally relocates it elsewhere.
TransferIt can also be confused with Transfer procedures coded to the Muscles body system when the primary moving structure is muscle tissue with the tendon simply following along, so the operative note's emphasis determines the correct body system.
