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
Head and Neck Tendon
Tendons of the head and neck include structures such as the temporalis tendon insertion and small tendinous slips associated with strap and mastication muscles in a region otherwise dominated by muscle rather than long tendons. Division here severs one of these tendons without removing any tissue, most often to release a contracture, correct an abnormal pull affecting jaw or neck posture, or lengthen a tight tendon contributing to torticollis-like findings. Because this territory is crowded with major vessels, cranial nerves, and the airway, the cut must be made with careful exposure to avoid these adjacent structures. The procedure changes the tendon's mechanical tension rather than its bulk, and the specific tendon divided should be documented precisely given how few discrete tendinous structures exist in this body region compared to the limbs.
Approach: Percutaneous
Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.
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.
