CPT® Code 22800

Arthrodesis, commonly known as spinal fusion, is a surgical procedure aimed at correcting spinal deformities, such as scoliosis or kyphosis, by fusing two or more vertebral segments together. This procedure is performed through a posterior approach, meaning the incision is made in the back, either in the neck or over the affected area of the spine. The primary goal of this surgery is to stabilize the spine and alleviate pain associated with the deformity. During the procedure, the surgeon carefully 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 bone graft) or from a donor (allograft bone). The bone graft is then placed along the prepared vertebrae to promote fusion. Additionally, internal fixation devices may be utilized to secure the vertebrae in place, ensuring proper alignment during the healing process. Depending on the extent of the surgery, a body cast may be applied post-operatively to provide further support. The CPT® Code 22800 specifically refers to the arthrodesis of up to six vertebral segments, while codes 22802 and 22804 are designated for fusions involving seven to twelve and thirteen or more vertebral segments, respectively.
