Joining together portions of an articular body part rendering the articular body part immobile

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

Shoulder Joint, Right

The right shoulder joint, or glenohumeral joint, is a highly mobile ball-and-socket articulation between the humeral head and the glenoid fossa of the scapula, surrounded by the rotator cuff and labrum that together allow the shoulder's exceptional range of motion. Fusion here, known clinically as glenohumeral arthrodesis, is a significant undertaking typically reserved for severe cases such as irreparable rotator cuff arthropathy, brachial plexus injury with a flail shoulder, chronic infection, failed arthroplasty, or recurrent instability where reconstruction is not viable, since it permanently sacrifices shoulder motion to achieve stability and pain relief. Because the procedure fundamentally trades mobility for a stable, pain-free limb, positioning of the arm at the time of fusion is critical and heavily documented, and the operative note should specify the fixation construct, typically plates and screws, used to achieve union between humerus and scapula.

Approach: Percutaneous Endoscopic

Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.

Device: Internal Fixation Device

Internal fixation device is the general value for hardware such as plates, screws, or rods placed within the body to stabilize bone or joint, used when a more specific configuration is not indicated. It stands in contrast to the named subtypes - Rigid Plate, Intramedullary, Sustained Compression, and Intramedullary Limb Lengthening - which specify how the hardware achieves stabilization.

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.

Commonly Confused With

ExcisionExcision is frequently performed as a preliminary step to prepare joint surfaces for fusion, but when the ultimate goal documented is immobilizing the joint, the case is coded as Fusion rather than Excision.
ReplacementReplacement is the key distinction from Fusion when a joint is severely damaged: Replacement substitutes the joint surfaces with a prosthetic device that preserves motion, while Fusion eliminates motion by joining the natural bones.
InsertionInsertion of hardware alone, without the intent to immobilize the joint permanently, is not Fusion; the defining factor is whether the procedure's purpose is to render the joint immobile.
