CPT® Code 64635

Destruction by neurolytic agent, paravertebral facet joint nerve(s), with imaging guidance (fluoroscopy or CT); lumbar or sacral, single facet joint

Paravertebral facet joints, also known as zygapophyseal joints, are critical structures located on the posterior aspect of the spine, situated on either side of the vertebrae where one vertebra overlaps another. These joints play a significant role in spinal movement and stability. The procedure described by CPT® Code 64635 involves the destruction of the paravertebral facet joint nerve(s) using a neurolytic agent, which is a chemical substance that can destroy nerve tissue. This procedure is performed with the assistance of imaging guidance, specifically fluoroscopy or computed tomography (CT), to ensure precise targeting of the nerve pathways. The use of imaging technology enhances the accuracy of the procedure, minimizing the risk of damage to surrounding tissues. The neurolytic agent is injected into the nerve pathway, effectively interrupting pain signals transmitted by the affected nerve, which can provide significant relief for patients suffering from chronic pain conditions associated with the facet joints. The procedure is typically performed on a single facet joint in the lumbar or sacral region, and it is essential for medical coders and billers to understand the specific details and indications for this intervention to ensure accurate coding and billing practices.
