Placement of X-Spine Axle Cage
A patient with lumbar stenosis and spondylolisthesis causing pain and weakness of the left leg was admitted for spinal surgery. At surgery, open central laminectomy with partial facetectomy and foraminotomy were performed at L4-L5. An X-Spine Axle Cage was filled with allograft and inserted between the posterior elements. Plates and pedicle screws were placed and the posterolateral gutters were packed with allograft bone and demineralized bone matrix for fusion. What are the procedure codes for placement of the X-Spine Axle Cage with allograft bone? ...

Article Overview
This article explains a spine surgery coding scenario involving lumbar stenosis and spondylolisthesis, operative decompression, and placement of an X-Spine Axle Cage with graft material. It is relevant to facility and professional coders who need to identify the appropriate procedure coding context for spinal stabilization and related operative work. The discussion centers on procedure selection for the implant and associated surgical components without providing broader policy guidance.
Why This Topic Matters
Spine surgery cases often combine multiple operative services, implants, and grafting materials, making accurate procedure classification important for compliant reporting and claim review. Understanding how this case is framed helps coders distinguish the implant-related service from the decompression and fusion components.
