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
Hip Muscle, Left
The left hip muscle group encompasses the gluteus maximus, medius, minimus, and the short external rotators such as piriformis, which together stabilize the pelvis and drive hip movement during ambulation. Complete resection of one of these muscles is generally performed for an aggressive soft tissue tumor, deep chronic infection with muscle necrosis, or a severe pressure injury eroding into the gluteal muscles, and losing an entire gluteal muscle often necessitates later reconstructive flap coverage given the functional and cosmetic prominence of this region. The sciatic nerve's course beneath or through some of these muscles makes precise, layer-by-layer dissection essential, and the operative note should clearly name which hip muscle was excised in full.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
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.
