CPT® Code 22869

Insertion of interlaminar/interspinous process stabilization/distraction device, without open decompression or fusion, including image guidance when performed, lumbar; single level

The procedure described by CPT® Code 22869 involves the insertion of an interlaminar or interspinous process stabilization or distraction device in the lumbar region of the spine. This procedure is specifically performed without open decompression or fusion and may include image guidance if necessary. The primary goal of this intervention is to stabilize and/or distract the neural foramen, which is the opening through which spinal nerves exit the vertebral column. The interlaminar devices are strategically placed adjacent to the lamina, utilizing two sets of wings that encircle the inferior and superior spinous processes, thereby limiting excessive movement that could exacerbate spinal conditions. On the other hand, interspinous spacers are small implants inserted between the spinous processes of the vertebrae. Once positioned, these spacers are expanded to alleviate pressure on the spinal nerves, which can be particularly beneficial for patients suffering from spinal stenosis, characterized by narrowing of the spinal canal that can lead to pain and neurogenic claudication. The procedure typically involves making a small incision over the targeted lumbar disc, followed by careful dissection through the surrounding tissues to access the spine. This minimally invasive approach aims to provide relief from symptoms while preserving as much surrounding tissue as possible.
