CPT® Code 63198

The procedure described by CPT® Code 63198 involves a laminectomy combined with a cordotomy, specifically targeting the anterior spinothalamic tracts in the cervical region. A laminectomy is a surgical procedure that entails the removal of a portion of the vertebral bone called the lamina, which allows access to the spinal cord. The primary goal of this procedure is to selectively destroy the spinothalamic tracts, which are critical pathways for transmitting pain sensations from the body to the brain. This procedure can be performed in two stages within a 14-day period, allowing for a more controlled approach to managing severe pain, particularly in terminally ill patients suffering from malignancies. The spinothalamic tracts are located bilaterally in the anterolateral aspect of the spinal cord, and their destruction can significantly alleviate unilateral pain. Although the use of cordotomy has diminished with the introduction of newer pain management techniques, it remains a viable option for patients experiencing intractable pain that is not responsive to other treatments. The surgical approach involves making an incision over the cervical or thoracic spine, retracting the muscles, and utilizing a bone drill to expose the spinal cord for the precise identification and sectioning of the spinothalamic tracts.
