CPT® Code 64626

The procedure described by CPT® Code 64626 involves the destruction of the paravertebral facet joint nerve using a neurolytic agent, specifically targeting a single level in the cervical or thoracic region of the spine. Paravertebral facet joints, also known as zygapophyseal joints, are located at the back of the spine, where adjacent vertebrae meet. This procedure is typically performed to alleviate pain associated with conditions affecting these joints. The process begins with the preparation of the skin over the facet joint, followed by the administration of a local anesthetic to minimize discomfort during the procedure. A spinal needle is then carefully guided into the facet joint space, where it is confirmed to be in the correct position through the injection of contrast material. Once the needle placement is verified, a neurolytic agent, which may include substances such as phenol, ethyl alcohol, or glycerol, is injected to destroy the nerve pathway. Alternatively, thermal or electrical modalities can be employed, where an electrode is used to generate heat that effectively destroys the targeted nerve tissue. This procedure is performed under fluoroscopic guidance to ensure precision and accuracy in targeting the nerve, ultimately aiming to provide pain relief for patients suffering from facet joint-related discomfort.
