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

Shoulder Tendon, Left

On the left side, the same rotator cuff and proximal biceps tendons are subject to excision when degeneration, calcific deposits, or partial tearing produce pain that persists despite conservative care. The subacromial location means the excised tissue is often removed alongside decompression of the surrounding bursa, and the coder should look for clear laterality documentation distinguishing left from right, since these procedures are frequently bilateral over a patient's history. Surgeons cutting out diseased tendon here must balance thoroughness against preserving the footprint needed for later repair, particularly in overhead athletes or laborers whose shoulder function depends on an intact cuff. Left-sided excision carries identical anatomic considerations to the right but is coded separately by convention.

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.

Commonly Confused With

ResectionResection is the closest neighbor and the distinction hinges entirely on whether the entire tendon was removed versus only a segment.
ExtirpationExtirpation can be confused with Excision when a mass being removed is actually loose or abnormal solid matter, like a foreign body or a discrete calcified nodule not integrated into the tendon structure, rather than a piece of the tendon itself.
DestructionDestruction differs because it eradicates tissue without physically removing it from the body, so no specimen exists for pathology, which is a helpful clue when the documentation is otherwise ambiguous.
