Summary & Overview
CPT 61860: Placement of Cortical Neurostimulator Electrodes
CPT code 61860 defines the neurosurgical placement of neurostimulator electrodes on the cerebral cortex after removal of a portion of the skull. This invasive operative code captures a specialized neuromodulation procedure used in select patients for seizure control, pain management, or experimental neuromodulation therapies. Nationally, the code matters because it represents high-acuity, resource-intensive care with implications for surgical staffing, facility resources, and device coverage.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and common billing considerations tied to this procedure. The publication outlines benchmarks for utilization and reimbursement patterns where available, summarizes relevant coding and policy updates that affect coverage and documentation, and highlights clinical factors that influence coding and payer decisions. Data on specific payer policies, prior authorization requirements, and payment rates are summarized when available; if not provided in the source, the reader is informed that detailed payer-specific data are not included. The analysis is intended for a national audience of billing professionals, neurosurgeons, revenue-cycle staff, and policy analysts seeking a clear reference for CPT code 61860 and its role in surgical neurostimulation care.
Billing Code Overview
CPT code 61860 describes a neurosurgical procedure in which a portion of the skull (craniectomy or craniotomy) is removed to place neurostimulator electrodes directly on the cerebral cortex, the outermost portion of the cerebrum. This procedure is performed to enable cortical neurostimulation for therapeutic neuromodulation.
-
Service type: Neurosurgical operative procedure for cortical neurostimulation electrode placement
-
Typical site of service: Hospital inpatient or hospital outpatient surgical setting, typically in an operating room with neurosurgical and neurophysiological monitoring capabilities
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient with medically refractory focal epilepsy is evaluated for cortical neurostimulation. After multidisciplinary review including neurology, epilepsy surgery, and neuropsychology, the patient undergoes a craniotomy to expose the cerebral cortex and placement of subdural or epidural neurostimulator electrodes on the cortical surface. Preoperative planning includes MRI brain with functional mapping and stereotactic planning; intraoperative neuronavigation and electrocorticography guide electrode positioning. The procedure typically occurs in an inpatient operating room under general anesthesia with neurosurgery as the primary provider and intraoperative neurophysiology monitoring. Postoperative workflow includes recovery in PACU or ICU for neurologic observation, postoperative imaging (CT or MRI) to confirm electrode position, programming of the neurostimulator by neurology or an authorized representative, and scheduled follow-up visits for device management and seizure- or symptom-monitoring.
