Official Description

Craniectomy for implantation of neurostimulator electrodes, cerebellar, cortical

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 61870 involves a craniectomy, which is a surgical operation where a portion of the skull is removed to access the brain. This specific procedure is performed for the implantation of neurostimulator electrodes, which are devices used to deliver electrical impulses to specific areas of the brain. In this case, the electrodes are placed in the outer part of the cerebellum, a region of the brain that plays a crucial role in motor control and coordination. The incision made in the skull allows the surgeon to carefully navigate to the cerebellum and accurately position the electrodes. This procedure is typically indicated for patients who may benefit from neuromodulation therapies aimed at treating various neurological conditions. The use of neurostimulator electrodes can help in managing symptoms by altering the electrical activity in the targeted brain regions, thereby providing therapeutic benefits to the patient.
