Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision covers cutting out a portion of an upper bone without replacing it, most often to obtain a tissue sample for diagnosis or to remove a tumor, cyst, or damaged segment while leaving the surrounding bone intact. Rib excisions are performed for suspected malignancy or to gain surgical access to the chest, clavicle and scapula excisions address tumors or nonunion fragments, and small excisional biopsies are done on the humerus, forearm bones, or hand bones when imaging shows an indeterminate lesion.
Because only a portion of the bone is taken and the rest of the structure remains, this differs from removing an entire bone or joint segment. The excised tissue is typically sent to pathology, and the remaining bone may need grafting or fixation depending on how much structural support was lost.
Anatomy & Axis Detail
Carpal, Left
In the left wrist, the carpal bones sit in two closely fitted rows that translate forearm rotation and tendon pull into precise hand movement, making them susceptible to avascular necrosis, cystic degeneration, and small tumors that erode cortical bone. Excision addresses these focal lesions, such as a symptomatic bone cyst in the scaphoid or a portion of necrotic lunate, without removing the entire carpal element. Surgeons must navigate the tight ligamentous network holding adjacent carpals together, since disrupting too much bone or its ligamentous attachments can produce instability patterns like scapholunate dissociation. Because the volar wrist crease houses the median nerve and flexor tendons, dorsal exposure is often preferred. The code applies specifically when a piece of carpal bone, not the whole structure, is cut out for diagnosis or treatment.
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
Coders need documentation confirming that a portion, not the entirety, of the named bone was cut out, along with the specific bone and, where relevant, whether the procedure was diagnostic. A biopsy that removes only a small sample for pathology still falls under Excision, with a qualifier indicating diagnostic intent.
The most frequent error is selecting Excision when an entire bone or a whole anatomical segment such as the whole clavicle was removed, which instead falls under Resection. Another common issue is failing to code bone grafting or fixation performed immediately afterward as separate procedures when the operative note describes them as distinct steps.
