Destruction by neurolytic agent, paravertebral facet joint nerve; cervical or thoracic, each additional level (List separately in addition to code for primary procedure)

The CPT® Code 64627 refers to the procedure of destruction by a neurolytic agent of the paravertebral facet joint nerve specifically in the cervical or thoracic regions 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 involves the use of a neurolytic agent, which is a chemical substance that destroys nerve tissue, thereby interrupting pain signals sent to the brain. The procedure is conducted under fluoroscopic guidance, ensuring precise targeting of the nerve. Prior to the injection of the neurolytic agent, the skin over the facet joint is prepared, and a local anesthetic is administered to minimize discomfort. The procedure may involve the use of a spinal needle to access the facet joint space, where contrast material is injected to confirm proper needle placement. Following this, the neurolytic agent is injected along the nerve pathway to achieve the desired therapeutic effect. Various neurolytic agents can be utilized, including phenol, ethyl alcohol, glycerol, ammonium salt compounds, and hypertonic or hypotonic solutions. Additionally, thermal or electrical modalities may be employed, where a probe or electrode is used to generate heat that destroys the nerve tissue. This procedure is typically reported separately for each additional cervical or thoracic level treated, following the primary procedure code.
