CPT® Code 64626

Deleted

1. Indications

The procedure described by CPT® Code 64626 is indicated for patients experiencing pain related to the cervical or thoracic paravertebral facet joints. This pain may arise from various conditions, including but not limited to:

• Facet Joint Syndrome A condition characterized by pain originating from the facet joints due to degeneration, inflammation, or injury.
• Chronic Neck Pain Persistent pain in the cervical region that may be associated with facet joint dysfunction.
• Thoracic Pain Pain in the thoracic spine that may be linked to facet joint issues, often exacerbated by movement or certain positions.

2. Procedure

The procedure for CPT® Code 64626 involves several critical steps to ensure effective destruction of the paravertebral facet joint nerve:

• Step 1: Preparation The skin over the targeted facet joint is thoroughly cleaned and prepped to reduce the risk of infection. A local anesthetic is then injected to numb the area, ensuring patient comfort during the procedure.
• Step 2: Needle Insertion A spinal needle is carefully directed into the facet joint space. The physician advances the needle until it encounters bone or cartilage, indicating the correct location. This step is crucial for accurate targeting of the nerve.
• Step 3: Contrast Injection A small amount of contrast material is injected through the needle to confirm its proper placement within the facet joint space. This imaging technique helps visualize the needle's position and ensures it is correctly aligned with the nerve pathway.
• Step 4: Verification of Placement Following the contrast injection, a local anesthetic and/or steroid may be administered to further verify the needle's correct placement along the nerve pathway.
• Step 5: Injection of Neurolytic Agent Once the needle is confirmed to be in the correct position, the selected neurolytic agent is injected along the nerve pathway. This agent may include phenol, ethyl alcohol, glycerol, or other chemical solutions designed to destroy nerve tissue.
• Step 6: Thermal or Electrical Modality (if applicable) In cases where thermal or electrical modalities are used, an electrode needle is introduced through the skin and advanced toward the targeted neural tissue. The needle is connected to a generator, and motor and sensory testing are performed to ensure accurate positioning. Once the correct nerve pathway is identified, the electrode is activated to generate heat, effectively destroying the targeted nerve tissue.

3. Post-Procedure

After the procedure, patients may experience some discomfort at the injection site, which is typically managed with standard post-procedure care. It is essential to monitor the patient for any immediate adverse reactions. Patients are usually advised to rest and may be given specific instructions regarding activity limitations. Follow-up appointments may be scheduled to assess the effectiveness of the procedure and to determine if additional treatments are necessary. The expected recovery time can vary based on individual patient factors and the extent of the procedure performed.
