CPT® Code 63170

The procedure described by CPT® Code 63170 refers to a laminectomy with myelotomy, specifically targeting the cervical, thoracic, or thoracolumbar regions of the spine. A laminectomy is a surgical procedure that involves the removal of a portion of the lamina, which is the bony arch of the vertebra that covers the spinal canal. This procedure is often performed to relieve pressure on the spinal cord or nerve roots. Myelotomy, on the other hand, involves making an incision into the spinal cord itself. This combination of procedures is typically indicated for patients suffering from intractable pain due to malignant neoplasms or neuropathic pain resulting from spinal nerve root avulsion. Additionally, it is utilized for managing end zone or boundary pain that may occur following a spinal cord injury. The surgical approach begins with an incision in the skin over the targeted spinal region, extending down to the spinous processes, allowing access to the underlying structures. The muscles are carefully retracted to expose the lamina and facet joint, and a bone drill is employed to remove the necessary bony structures to access the spinal cord. The myelotomy is then performed at the appropriate spinal cord region, which may involve techniques such as DREZ lesioning or Bishop myelotomy, each serving specific therapeutic purposes in pain management and spasticity treatment.
