Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Tendon excision procedures cut out and remove a portion of a tendon without replacing it, typically to address a tumor, a chronically degenerated segment, a painful nodule, or scar tissue that is limiting motion. A well-known example is excision of a trigger finger nodule or a portion of tendon affected by tenosynovitis that has not responded to more conservative treatment, as well as biopsy of a suspicious mass for diagnostic purposes.
Because only part of the tendon is taken and the remainder is left in place, the surgeon must weigh how much tissue can be safely removed without compromising the tendon's mechanical function. In many cases the excised tissue is sent to pathology, which both confirms the diagnosis and distinguishes this procedure from techniques that simply destroy tissue in place.
Anatomy & Axis Detail
Thorax Tendon, Left
Left thorax tendon excision addresses chest wall tendinous structures analogous to the right side, most often the pectoral or serratus anterior tendon insertions, which may develop chronic tendinosis, calcific change, or postsurgical scar tissue causing localized pain or limited arm elevation. Given the tendon's proximity to the rib cage and underlying thoracic structures, the excision is performed with attention to avoiding pleural injury, and only the pathologic tissue is removed rather than the full tendon. This procedure is uncommon relative to shoulder or arm tendon work, so clear documentation of the specific tendon, its left-sided location, and the extent of tissue removed is necessary to support accurate coding and to differentiate it from chest wall muscle or rib procedures.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Qualifier: Diagnostic
Applied chiefly to Excision, this qualifier marks that tissue was removed specifically for diagnostic purposes, i.e., a biopsy intended for pathologic evaluation rather than to treat disease. It distinguishes biopsy-type excisions from therapeutic excisions of the same body part, which are coded without this qualifier even though the physical technique may be identical.
Coding & Documentation
A code from this family is appropriate when the operative note documents cutting out and removing a defined portion of tendon tissue, with the remaining tendon left intact and nothing reconstructed at the same time. Look for language describing a specimen sent to pathology, the anatomic tendon and location, and confirmation that the entire tendon was not removed, which would instead point toward Resection.
A common mistake is coding Excision when the whole tendon was actually removed, since ICD-10-PCS distinguishes cutting out "all or a portion" only when characterizing the two operations differently, that is, Excision for a portion and Resection for all of a body part. Coders also sometimes overlook a concurrent repair, such as a tendon graft or suture closure performed after excision, which requires a separate code if it meaningfully restores structure beyond simple wound closure.
