CPT® Code 61490

The procedure described by CPT® Code 61490 refers to a craniotomy for lobotomy, which includes a cingulotomy. This psychosurgical intervention is characterized by its rarity in contemporary medical practice, primarily due to the evolution of psychiatric treatments and ethical considerations surrounding its use. Historically, lobotomy was employed to address various mental health disorders, particularly those that involved severe behavioral disturbances, such as violent episodes, as well as conditions like medically intractable obsessive-compulsive disorder, refractory depression, and chronic pain syndromes. The surgical approach begins with an incision made in the skin over the scalp, typically at the top of the head or the forehead, allowing access to the underlying cranial structures. Following this incision, the frontal bone is exposed, and burr holes are drilled into the skull. The surgical team may choose to perform the procedure through these burr holes or utilize a saw to connect them, thereby creating a bone flap that provides a direct view of the frontal lobe. Once access is achieved, an incision is made through specific nerve tracts within the frontal lobe. The procedure specifically targets the cingulate gyrus, where the nerve fiber bundle is located, and involves severing the nerve fibers that link the frontal lobes to the limbic system, which is crucial for emotional regulation and behavior. This complex procedure requires careful planning and execution, given its implications for the patient's mental and emotional health.
