CPT® Code 22868

Add-On Code

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

The procedure described by CPT® Code 22868 involves the insertion of an interlaminar or interspinous process stabilization or distraction device in the lumbar region of the spine. This procedure is performed without fusion and includes image guidance when applicable. The primary goal of this intervention is to stabilize the lumbar spine and alleviate pressure on the spinal nerves, particularly in patients suffering from conditions such as spinal stenosis, which can lead to pain and neurogenic claudication. The interlaminar devices are strategically placed adjacent to the lamina and feature two sets of wings that encircle the inferior and superior spinous processes, thereby limiting excessive movement. Conversely, interspinous spacers are smaller devices that are inserted between the spinous processes and expanded to relieve nerve pressure. The procedure typically involves making a small incision over the targeted lumbar disc, followed by careful dissection through the subcutaneous tissue and deeper layers to access the spine. This meticulous approach allows for the effective decompression of the exiting and transversing nerve roots, ultimately aiming to improve the patient's quality of life by reducing pain and enhancing mobility.
