CPT® Code 22870

Add-On Code

Insertion of interlaminar/interspinous process stabilization/distraction device, without open decompression or fusion, including image guidance when performed, lumbar; second level (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 22870 involves the insertion of an interlaminar or interspinous process stabilization or distraction device specifically at the second level of the lumbar spine. This procedure is performed without open decompression or fusion and includes image guidance when applicable. 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 to limit excessive movement. In contrast, interspinous spacers are small implants inserted between the spinous processes of the vertebrae and are expanded to alleviate pressure on the spinal nerves. This procedure is particularly indicated for adults suffering from spinal stenosis, which can lead to symptoms such as pain and neurogenic claudication. The surgical approach typically involves making a small incision over the targeted lumbar disc(s) and carefully dissecting through the subcutaneous tissue and surrounding structures to access the spine. The procedure is designed to enhance stability and relieve nerve compression, ultimately improving the patient's quality of life.
