Operation Definition
Cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part
Procedure Overview
Tendon division procedures cut through a tendon to separate it, without draining any fluid or removing tissue. The classic example is a tenotomy performed to release excessive tension, most often in children or adults with contractures from conditions like clubfoot, cerebral palsy, or spasticity, where lengthening a tight tendon improves joint mobility and gait. The tendon is deliberately transected, sometimes at multiple levels, and allowed to heal in a lengthened position, or it may be left divided to eliminate an abnormal pulling force altogether.
Because the intent is purely to cut and separate rather than to remove tissue or drain fluid, this is a comparatively contained procedure that can often be done percutaneously with a small blade, avoiding an open incision. Patients typically need bracing or casting afterward to hold the limb in the corrected position while the tendon reattaches or scars into its new length.
Anatomy & Axis Detail
Abdomen Tendon, Left
On the left side, the abdomen tendon comprises the tendinous insertions and aponeurotic bands of the lateral and anterior abdominal wall muscles. Division of this tissue is a maneuver most commonly associated with component separation techniques used to bridge large hernia defects, allowing the muscular layers to shift toward the midline while preserving their neurovascular supply. It can also be used to address a fixed contracture limiting trunk flexion or rotation. Surgeons approach this region mindful of the proximity to the peritoneal cavity and the need to protect segmental intercostal nerves running through the lateral wall. Accurate documentation of laterality and the specific tendinous structure cut is important, since abdominal wall anatomy varies in thickness and fiber orientation from the flank to the midline.
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
A Division code applies when the documentation describes cutting or transecting the tendon to separate it, with no fluid or gas drainage and no tissue taken out of the body. Percutaneous tenotomy notes should state the tendon involved, the technique (open versus percutaneous), and confirm that the procedure's purpose was releasing tension or separating the structure rather than excising a lesion.
A common coding pitfall is confusing tenotomy performed for lengthening with tenotomy performed as an approach step to reach a deeper structure, which would not be separately coded. Coders also sometimes miss that if the surgeon removes a piece of the tendon rather than simply cutting through it, the case belongs under Excision instead, so precise reading of whether tissue was taken out is essential.
