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, Right
The right shoulder muscle group includes the deltoid, rotator cuff muscles, and other structures spanning the glenohumeral joint, tissues that are frequently biopsied or partially resected when a soft tissue mass, chronic tendinopathy-associated nodule, or traumatic muscle tear with nonviable tissue is identified. Because the shoulder is a highly mobile joint surrounded by a complex arrangement of muscles working in coordination, excising even a portion of one muscle can affect strength and range of motion, so surgeons aim to remove only the pathological tissue while sparing as much functional muscle as possible. The subacromial space and surrounding bursae are often close to the surgical field, adding anatomic considerations during dissection, and documentation should specify which of the several right shoulder muscles was excised given how functionally distinct each one is.
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.
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
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.
