Insertion of posterior spinous process distraction device (including necessary removal of bone or ligament for insertion and imaging guidance), lumbar; single level

The procedure described by CPT® Code 0171T involves the insertion of a posterior spinous process distraction device specifically in the lumbar region of the spine at a single level. This minimally invasive technique is designed to alleviate symptoms associated with lumbar stenosis, which often occurs alongside degeneration of the intervertebral disc and a reduction in disc height. Patients may experience neurogenic claudication, characterized by pain and discomfort in the lower extremities due to nerve compression. During the procedure, an incision is made over the targeted intervertebral disc space, allowing access through the skin, subcutaneous tissue, and lumbosacral fascia to expose the inferior and superior spinous processes, as well as the interspinous ligament. The procedure may require the removal of bone or ligament to facilitate the insertion of the distraction device. Imaging guidance, such as fluoroscopy, is utilized to ensure proper alignment and positioning of the device during and after the insertion process. This technique is also referred to as interspinous distraction or interspinous process decompression (IPD), and it aims to create more space within the spinal canal, thereby relieving pressure on the spinal nerves.
