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
Sternum
The sternum is the flat, midline bone of the anterior chest wall that anchors the ribs via costal cartilage and protects the heart and great vessels lying just behind it. Excision of sternal tissue is performed for chronic osteomyelitis, most often following prior cardiac surgery through a median sternotomy, for tumor involving the bone, or for debridement of nonviable segments after a failed sternal closure. Because the sternum sits directly over the mediastinum, excision requires careful attention to avoid injury to the heart, internal mammary vessels, and great vessels immediately posterior to the bone, and any defect created often requires later reconstruction with muscle or omental flaps. The extent of bone removed, whether a portion or the entire sternum, should be clearly documented since it affects both coding and reconstructive planning.
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.
Qualifier: Diagnostic
Applied chiefly to Excision, this qualifier marks that tissue was removed specifically for diagnostic purposes, i.e., a biopsy intended for pathologic evaluation rather than to treat disease. It distinguishes biopsy-type excisions from therapeutic excisions of the same body part, which are coded without this qualifier even though the physical technique may be identical.
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.
