CPT® Code 22802

Arthrodesis, commonly known as spinal fusion, is a surgical procedure aimed at correcting spinal deformities, such as scoliosis or kyphosis, by fusing together two or more vertebral segments. This procedure is specifically referred to as posterior arthrodesis when the surgical approach is from the back of the body. The primary goal of this intervention is to stabilize the spine and alleviate pain associated with spinal deformities. During the procedure, an incision is made either in the back of the neck or along the back over the affected spinal area, allowing access to the vertebrae. The surgical team dissects the soft tissues to expose the vertebrae, removes the facet joints, and prepares the vertebral segments for the application of a bone graft. This graft can be obtained from the patient's own body (autogenous) or from a donor (allograft). The bone graft is then placed between the vertebrae to promote fusion, and internal fixation devices may be used to secure the vertebrae in place. Depending on the extent of the surgery, a body cast may be applied post-operatively to support the spine during the healing process. This procedure is indicated for patients requiring significant correction of spinal deformities and is categorized based on the number of vertebral segments involved, with CPT® Code 22802 specifically designated for the fusion of 7 to 12 vertebral segments.
