Operation Definition
Restoring, to the extent possible, a body part to its normal anatomic structure and function
Procedure Overview
Repair procedures on tendons address damage from lacerations, partial tears, or defects that need to be closed or restored using suture or local tissue, without replacing the tendon with graft material or moving it to a new anatomic position. This is the default root operation for tendon surgery whenever no more specific objective, such as replacement, reposition, or resection, applies. A classic example is suturing a lacerated flexor tendon in the hand after a knife injury, or closing a partial tear in the Achilles tendon.
These procedures are performed to restore a tendon's ability to transmit muscle force to bone, which is essential for normal joint movement. Left unrepaired, a torn or lacerated tendon can lead to permanent loss of motion or strength in the affected limb, so timely repair is often emphasized, particularly for tendons in the hand and wrist where scarring and adhesions can quickly limit the surgical window.
Anatomy & Axis Detail
Knee Tendon, Left
On the left side, the knee tendon group includes the patellar tendon linking the quadriceps to the tibia and the popliteus tendon supporting rotational stability of the joint. These structures are commonly injured through forceful quadriceps contraction against a flexed knee, such as in a missed step or athletic cutting maneuver, resulting in mid-substance tears or bony avulsions. Surgical repair brings the disrupted tendon edges back together, frequently anchoring the tendon to bone with sutures passed through drill holes, and aims to restore native length and tension rather than augment it with graft material. Because an untreated tear leaves the patient unable to actively extend the knee, timely repair and clear documentation of the specific tendon and technique are important for both clinical and coding purposes.
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 assign a Repair code when the documentation describes suturing, direct closure, or similar restoration of tendon continuity using the patient's own tissue, without a graft substituting for missing tendon substance. The operative note should specify which tendon and where along its course the repair occurred, since ICD-10-PCS body part values distinguish tendons by region rather than by naming every individual tendon.
The most common assignment error is choosing Repair by default without first ruling out a more specific root operation; if the surgeon used graft material to bridge a tendon gap, Replacement is more accurate, and if the tendon was cut and moved to a different location for realignment, Reposition applies instead. Another frequent miss is failing to code a separate procedure when Repair is done as an unplanned part of a more complex operation, such as fixing an incidental tendon nick during another surgery.
