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 Arm Muscle, Left
On the left upper arm, the biceps brachii, triceps brachii, and brachialis form a substantial muscle mass that surgeons access to excise tumors, obtain diagnostic tissue samples, or remove damaged muscle after significant trauma such as a laceration or crush injury. The radial nerve wraps around the humerus in this region and the musculocutaneous nerve travels between the biceps and brachialis, so surgeons must carefully trace and protect these structures throughout the dissection to avoid causing sensory or motor deficits in the forearm and hand. Because these muscles are large relative to many others in the body, a partial excision can often be performed while preserving overall arm function, and coding should identify the specific muscle involved since the anterior and posterior compartments of the arm are functionally and anatomically distinct.
Approach: Percutaneous
Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.
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.
