Operation Definition
Cutting out or off, without replacement, all of a body part
Procedure Overview
Resection covers the surgical removal of an entire bone or a complete anatomically distinct portion of a bone within the skull, facial skeleton, thorax, or upper limb, without any device or material put in its place as part of the same code. Examples include removal of an entire clavicle for a tumor, excision of a whole rib, or removal of a full carpal bone.
This is typically performed for aggressive bone tumors, severe infection such as osteomyelitis that has destroyed the bone, or as part of a larger reconstructive plan where the diseased segment must come out before any rebuilding can occur. Because no replacement device is coded here, resection is often just the first step of a staged repair.
Anatomy & Axis Detail
Ribs, 3 or More
This body part value covers resection of three or more ribs, typically performed for extensive chest wall tumors, flail chest reconstruction following severe trauma, or radical resection margins around a malignancy invading the thoracic cage. Because the ribs form a continuous, load-bearing cage that supports respiratory mechanics, removing multiple contiguous segments destabilizes the chest wall and almost always requires simultaneous reconstruction with mesh, methylmethacrylate, or rigid plating to prevent paradoxical chest wall motion and preserve ventilatory function. The extent of resection is also dictated by the need for adequate oncologic margins when malignancy is present, and surgeons must balance thoroughness of excision against the physiologic consequences of a large chest wall defect. Coders should confirm the operative note specifies three or more ribs cut out, distinguishing this from resection limited to ribs one or two.
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 key documentation requirement is that the entire named body part, or a coded subdivision of it, is removed - partial removal of a bone that leaves a portion behind should be coded as excision instead, which falls outside this family. Coders need to check the specific body part values available for upper bones, since some are defined at the level of an individual bone (clavicle, scapula) while others are grouped, which changes whether a partial removal still qualifies as resection. A frequent error is coding resection when only a segment of a long bone like the humerus was removed rather than the whole bone, which should be excision. Another is failing to code a separate replacement or supplement procedure when reconstruction was performed in the same operative session.
