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
Upper Leg Muscle, Right
Right upper leg muscle covers the thigh musculature on that side, including the quadriceps, hamstrings, and adductor groups, extending from the hip to the knee. Excision is most often performed to remove a soft tissue sarcoma or benign tumor such as a lipoma, or to obtain a diagnostic biopsy of a thigh mass identified on imaging. The thigh's large muscle volume and well-defined fascial compartments often allow wider resection with less functional consequence than in smaller muscle groups, though tumors near the femoral vessels or sciatic nerve require more cautious dissection. Because the thigh is a common site for both primary soft tissue sarcomas and metastatic deposits, excision here frequently occurs in an oncologic context with attention to margin status.
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.
