Summary & Overview
CPT 61760: Implantation of Depth Electrodes for Epilepsy Localization
CPT code 61760 covers the surgical implantation of intracranial depth electrodes into the cerebrum with three-dimensional imaging guidance to map electrode positions and identify the epileptogenic focus. This procedure is clinically significant for patients with drug-resistant epilepsy when noninvasive monitoring cannot precisely localize seizure onset. Nationally, the code is relevant for neurosurgery programs, epilepsy centers, and payers managing high-cost, specialized neurodiagnostic services.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical intent and typical care setting for the procedure, plus an overview of the types of benchmarks and policy topics commonly associated with this code: utilization patterns at tertiary centers, coverage criteria for invasive seizure localization, coding and billing practice considerations, and potential implications for bundled or episode-based payment models. Data supporting payer-specific rates or utilization are not included here; note where input data is missing is indicated as "Data not available in the input." The summary equips clinicians, coding professionals, and policy analysts with a national-level understanding of what 61760 represents and the practical contexts in which the code is applied.
Billing Code Overview
CPT code 61760 describes the implantation of depth electrodes into the cerebrum using three-dimensional imaging guidance to map electrode locations. The procedure is performed to localize the cerebral region responsible for a patient’s epileptic seizures.
-
Service type: Surgical implant procedure for intracranial depth electrode placement with image-guided localization
-
Typical site of service: Inpatient or outpatient hospital operating room or dedicated neurosurgical procedure suite
Clinical & Coding Specifications
Clinical Context
A typical patient is a 22–45-year-old adult with medically refractory focal epilepsy who continues to experience complex partial or focal seizures despite trials of multiple anti-epileptic medications. The patient undergoes comprehensive noninvasive presurgical evaluation including prolonged video-electroencephalography (EEG) monitoring, high-resolution brain MRI, magnetoencephalography (MEG) or PET/SPECT as indicated, and neuropsychological testing. When noninvasive data are discordant or localizing information remains uncertain, the neurosurgeon and epileptologist plan an invasive monitoring procedure.
In the operating room under general anesthesia, the provider implants intracerebral depth electrodes into targeted cerebral regions using three-dimensional imaging guidance (stereotactic or frameless neuronavigation) to precisely map seizure onset zones. Leads are secured to the scalp or skull and tunneled to an externalized connector for subsequent inpatient video-EEG monitoring in a specialized epilepsy monitoring unit. The clinical workflow includes preoperative planning with image fusion, intraoperative localization and placement of electrodes, postoperative imaging to confirm position, and several days of inpatient electrophysiologic recording to capture and localize ictal events for potential resective or ablative surgery planning.
