CPT® Code 63197

Laminectomy with cordotomy, as described by CPT® Code 63197, involves a surgical procedure aimed at selectively destroying the anterior spinothalamic tract, which is the primary pathway for pain transmission within the spinal cord. This tract is situated bilaterally in the anterolateral aspect of the spinal cord, with each side transmitting sensory information from the opposite side of the body to the brain. The procedure is typically indicated for patients experiencing severe unilateral pain, often due to malignancy, particularly in terminally ill individuals. Although advancements in pain management techniques have reduced the frequency of cordotomy procedures, it remains a viable option in specific cases where pain relief is critical. The surgical approach begins with an incision over the thoracic vertebrae, extending down to the spinous processes, allowing access to the spinal structures. Through careful dissection and retraction of the surrounding muscles, the lamina is removed using a bone drill, ultimately exposing the spinal cord. The targeted spinothalamic tracts are then identified and sectioned on both sides of the thoracic spinal cord, effectively interrupting the pain transmission pathway.
