Procedure Overview
Fusion procedures permanently join the bones of a joint together so it can no longer move, a technique most often applied to small joints of the wrist and fingers, or occasionally the shoulder, when arthritis, instability, or severe deformity has made the joint too painful or unreliable to preserve. By eliminating motion at that single joint, fusion is intended to relieve pain and restore stability, accepting stiffness in exchange for a more predictable, load-bearing joint.
Surgeons commonly perform fusion for advanced wrist arthritis, for a badly damaged finger joint following trauma or rheumatoid disease, or as a salvage option after a failed joint replacement. The bones are prepared, aligned, and held together with hardware such as plates, screws, wires, or a bone graft while the surfaces knit into a single solid unit over subsequent months.
Anatomy & Axis Detail
Sternoclavicular Joint, Left
The left sternoclavicular joint provides the same axial-to-appendicular skeletal connection as its right counterpart, joining the medial clavicle to the sternal manubrium and cushioned by an intra-articular disc that allows limited gliding and rotational movement during shoulder motion. Indications for fusion parallel those on the right side, including refractory instability, arthritic degeneration, or unreduced traumatic dislocation, and the same anatomic risk applies given the joint's position just anterior to the great vessels and airway. Surgeons documenting this procedure should note the specific fixation technique chosen, since certain hardware types carry recognized risk of posterior migration in this location. Because the sternoclavicular joint is a distinct anatomic structure from the acromioclavicular joint despite both involving the clavicle, precise laterality and joint identification in documentation are essential for accurate procedural capture.
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.
Device: Synthetic Substitute
Synthetic Substitute designates a device made from manufactured, non-biologic material, such as mesh or prosthetic components, used to replace or augment a body part. It is distinguished from the two tissue substitute categories by its artificial composition, which carries different considerations for integration and long-term durability than biologic grafts.
Coding & Documentation
The coder must identify the specific joint fused, the approach (open, percutaneous, or percutaneous endoscopic), and the device qualifier reflecting what was used to hold the joint immobile, whether internal fixation, a bone graft from the patient's own body, synthetic substitute, or a combination of graft and internal fixation. A frequent error is choosing the wrong device qualifier when both an autograft and hardware are used together, since ICD-10-PCS has a specific combination qualifier for that scenario rather than defaulting to just "internal fixation device." Another common oversight is failing to code the bone graft harvest separately when it is taken from a different, non-contiguous body part.
