Procedure Overview
Fusion, also called arthrodesis, permanently joins the bones of a lower joint so that the joint can no longer move, converting a painful or unstable joint into a solid, stable one. It is used on the hip, knee, ankle, foot, and lumbar or lumbosacral spinal joints for conditions like severe arthritis, joint instability, failed prior surgery, deformity correction, or chronic pain that has not responded to less invasive treatment. Hardware such as screws, plates, or rods, sometimes combined with a bone graft, holds the joint surfaces together while they grow into one continuous piece of bone.
Because fusion eliminates motion at the treated joint, it is generally considered after other options such as medication, injections, or partial procedures have failed to control symptoms. Spinal fusion in the lumbar region is one of the most common examples, performed for conditions like degenerative disc disease, spondylolisthesis, or spinal instability.
Recovery typically takes several months as the bone heals across the joint, and patients can expect a trade of joint mobility for pain relief and structural stability.
Anatomy & Axis Detail
Tarsometatarsal Joint, Left
On the left foot, the tarsometatarsal joints anchor the cuneiforms and cuboid to the metatarsal bases and form the keystone of the midfoot arch. These joints are fused when Lisfranc injuries destabilize the midfoot, when degenerative arthritis develops at the first tarsometatarsal joint in association with bunion deformity, or when a collapsing arch requires rigid midfoot support. Because the five rays articulate somewhat independently, surgeons may fuse only the medial column or extend hardware across several rays depending on the pattern of instability. Given this variability, records should specify precisely which tarsometatarsal joint or joints were addressed in a given procedure, since a limited first-ray fusion and a broader midfoot arthrodesis are captured with different codes.
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, Sustained Compression
A sustained compression internal fixation device applies continuous, ongoing compressive force across a fracture or osteotomy site, such as a compression staple or nitinol-based implant, to promote bone healing through persistent apposition. It differs from a standard rigid plate or intramedullary device, which stabilize the bone but do not actively maintain compression over time.
Coding & Documentation
Coders need documentation confirming that articular surfaces were joined with the intent of eliminating motion, along with the device used (bone graft substitute, autograft, nonautograft, or internal fixation) and, for spinal fusion, the number of vertebral joints involved, since each level typically requires its own code. A frequent error is under-coding multilevel spinal fusions by capturing only one joint level instead of each level fused. Another common mistake is confusing the qualifier for graft material, since autologous bone graft, synthetic substitute, and no-graft fixation all carry different qualifier values that materially change the code. Coders should also check whether an anterior and posterior approach were both performed at the same spinal level, which requires separate codes for each approach.
