CPT® Code 22600

Arthrodesis, specifically the posterior or posterolateral technique, is a surgical procedure aimed at fusing one or more intervertebral joints in the cervical spine, particularly below the C2 segment. This procedure is commonly referred to as spinal fusion and is indicated for the treatment of conditions such as fractures or instability within the cervical vertebrae. The surgical approach involves making an incision in the back of the neck or over the affected vertebral joints, allowing access to the spine. During the procedure, soft tissues are carefully dissected to expose the vertebrae, and any necessary treatments for fractures or decompression are performed as separate reportable procedures. The preparation for fusion includes the meticulous preparation of the transverse processes, facet joints, and/or laminae to facilitate the placement of a bone graft. This graft can be harvested from the iliac crest or another site, and allograft bone from a bone bank may also be utilized. Once the graft is placed, drill holes are created in the vertebrae to secure the joint, either through wires or other internal fixation devices. The procedure concludes with the placement of a drain if necessary, followed by the closure of the surgical wound in layers. The specific CPT® code for this procedure is 22600, which is designated for the fusion of a single interspace of the cervical spine below the C2 segment.
