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
Neck Muscle, Left
On the left side of the neck, excision addresses muscles like the sternocleidomastoid, scalenes, or infrahyoid group, structures that sit adjacent to the thyroid gland, carotid artery, and multiple cranial and cervical nerves. Surgeons remove portions of these muscles to excise tumors, sample tissue for biopsy when malignancy is suspected, or resect scarred or damaged muscle following trauma or prior neck surgery, and the crowded anatomy of this region means dissection must be precise to avoid injuring nearby vascular and neural structures. Because the left neck also lies near the thoracic duct, particular care is taken during deeper excisions in this area, and coding should specify the exact muscle involved since the left neck contains multiple distinct muscle groups that could otherwise be conflated in documentation.
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.
