Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision procedures on the muscles remove a portion of a muscle, but not the entire structure, most commonly to obtain a biopsy sample, to debride damaged or infected tissue, or to remove a localized mass or lesion within the muscle. The remainder of the muscle stays in place and continues to function.
This family covers a wide range of clinical situations, from a small diagnostic biopsy of muscle tissue to evaluate a suspected myopathy, to debridement of necrotic muscle following trauma or severe infection, to removal of a benign tumor confined to a muscle. What ties these together is that only part of the muscle is taken, leaving the rest intact.
Because the tissue removed is often sent for pathological or microbiological analysis, excision plays a diagnostic role in many cases in addition to a therapeutic one.
Anatomy & Axis Detail
Shoulder Muscle, Left
On the left shoulder, excision targets muscles such as the deltoid, supraspinatus, or other rotator cuff components, tissues that stabilize and move the glenohumeral joint through an unusually wide range of motion. This procedure is generally performed to remove a soft tissue tumor, biopsy a mass suspicious for malignancy, or excise degenerated tissue from a chronic tear, and because shoulder muscles work in concert to maintain joint stability, surgeons typically limit removal to the diseased segment to avoid compromising function. The subacromial bursa and long head of the biceps tendon often lie near the operative field, requiring careful identification during dissection to prevent inadvertent injury. Given the number of distinct muscles in this region, precise documentation of which left shoulder muscle was excised is important for accurate procedural records.
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
Documentation should describe cutting out a portion, sample, or segment of muscle, with the specific muscle named and the extent of tissue removed described clearly enough to distinguish it from removal of the whole muscle. Pathology or culture results are often present when the excision was diagnostic.
One recurring mistake is coding Excision for debridement performed at the bedside without excisional technique, which if truly nonexcisional would not be captured under Muscles Excision at all, or coding Excision when in fact the entire muscle was taken, which should be Resection. Coders also need to be careful not to code a biopsy as Extraction, since cutting tissue out is Excision even when the intent is purely diagnostic.
