Operation Definition
Cutting out or off, without replacement, all of a body part
Procedure Overview
This family of procedures covers the complete surgical removal of an entire named muscle, without any replacement tissue put in its place. Surgeons turn to muscle resection most often when a tumor has grown within or fixed itself to the muscle body, when infection has destroyed the muscle beyond salvage, or when severe trauma has left the tissue non-viable. Removing the whole muscle, rather than trimming away only the diseased portion, is typically chosen when partial removal would leave behind disease or dead tissue that could spread infection or allow a cancer to recur.
Because an entire muscle is taken, these operations often affect movement or strength at the joint the muscle once controlled, so they are frequently paired with reconstructive planning, physical therapy, or a transfer procedure using a nearby muscle to take over the lost function. Patients considering or recovering from this kind of surgery are usually managing a serious underlying condition such as sarcoma, gas gangrene, or a crush injury rather than a routine orthopedic complaint.
Anatomy & Axis Detail
Upper Arm Muscle, Right
The right upper arm muscles, including the biceps, triceps, and brachialis, are responsible for elbow flexion and extension, and complete resection of one of these muscles is performed primarily for malignant soft tissue tumors, such as sarcomas arising within the muscle belly, or for extensive traumatic muscle destruction beyond salvage. Because the upper arm houses the brachial artery and the median, radial, and ulnar nerves running in close relation to these muscles, resection requires careful dissection to preserve these structures whenever oncologically feasible. Loss of a major upper arm muscle like the biceps or triceps significantly affects elbow function, so reconstructive procedures such as muscle transfer are often planned in conjunction, and the specific muscle resected should be documented precisely.
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
The operative note must clearly document that the entire named muscle was excised, not just a margin, lesion, or portion of it - phrases like "total resection of the gastrocnemius" support this code, while "debulking" or "partial excision" point toward Excision instead. The pathology or surgeon's description of the specimen (whole muscle versus a wedge or nodule) is the deciding factor coders rely on when the note is ambiguous. The most frequent assignment error is defaulting to Resection whenever a muscle mass is removed, without confirming the surgeon took the entire muscle rather than just the tumor within it. A second common mistake is missing laterality or the specific muscle name, which affects the body part value and can misrepresent the extent of surgery performed.
Commonly Confused With
Resection is easily confused with Excision, which cuts out only a portion of the muscle - the distinguishing question is always "all of the muscle or part of it?" It is also sometimes mixed up with Detachment, used when a limb or body part is amputated at a joint level rather than a single muscle being taken out, and with Destruction, which eliminates tissue with energy (such as cautery) rather than cutting it out and removing a specimen.
