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
Thorax Tendon, Right
The tendons of the right thorax include tendinous attachments of the intercostal and chest wall musculature that contribute to rib cage mechanics and, indirectly, respiratory movement. Division of one of these tendons is performed to release an abnormal contracture or tension, an infrequent indication typically arising from scarring after trauma or thoracic surgery, by cutting through the fibers without removing tissue. Because the thoracic cage overlies the pleura, lungs, and major vessels, this procedure demands careful superficial dissection to isolate the tendon from deeper structures before any cut is made. Thorax tendons are less distinctly defined than limb tendons and can be difficult to separate from surrounding fascia, so the operative note should clearly identify the specific tendon divided to support accurate documentation of this uncommon procedure.
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.
