CPT® Code 22854

Add-On Code

Insertion of intervertebral biomechanical device(s) (eg, synthetic cage, mesh) with integral anterior instrumentation for device anchoring (eg, screws, flanges), when performed, to vertebral corpectomy(ies) (vertebral body resection, partial or complete) defect, in conjunction with interbody arthrodesis, each contiguous defect (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 22854 involves the insertion of an intervertebral biomechanical device, which may include synthetic cages or meshes, into the spinal column. This procedure is specifically performed in conjunction with a vertebral corpectomy, which is the surgical removal of all or part of a vertebral body. The primary goal of this intervention is to decompress the spinal cord and nerves, thereby alleviating symptoms associated with conditions such as degenerative disc disease, spinal stenosis, or the presence of bone spurs (osteophytes). The insertion of the biomechanical device aims to restore the intervertebral disc space and achieve proper anatomic alignment of the spine. During the procedure, surgical immobilization of the spine is achieved through interbody arthrodesis, which involves fusing adjacent vertebrae to stabilize the spinal structure. The biomechanical device, typically designed in a cylindrical or square shape, can be filled with autogenous bone material to facilitate the fusion process. The surgical approach varies depending on the location of the procedure; for cervical placements, a horizontal incision is made on the side of the neck, while for lumbar placements, an incision is made on the left side of the abdomen. In both cases, careful dissection is performed to access the intervertebral disc space or vertebral body defect, allowing for the effective placement of the device. Integral anterior instrumentation, such as screws or flanges, may be utilized to secure the device in place, ensuring stability and support during the healing process.
