Summary & Overview
CPT 61535: Removal of Intracranial Electrode Array
CPT code 61535 denotes the surgical removal of an electrode array positioned on or beneath the dura mater by elevating a portion of the skull bone. This neurosurgical explantation is clinically significant for patients with intracranial monitoring or neurostimulation devices and can affect hospital resource use, perioperative planning, and device management protocols nationally. Payers commonly involved in coverage decisions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
This publication summarizes the clinical context for 61535, outlines typical sites of service, and presents what readers need to know about billing and policy implications at a national level. Readers will find: concise clinical description and service setting, common modifiers and billing considerations, payer coverage landscape, and references to related procedural categories. Data not available in the input for specific ICD-10 pairings, taxonomies, or payer-specific reimbursement benchmarks is noted where applicable.
The analysis is intended for health policy professionals, coding specialists, and clinicians involved in neurosurgical device management, providing a clear overview of the procedure coding, operational implications, and areas where payer guidance typically applies.
Billing Code Overview
CPT code 61535 describes a surgical procedure in which a provider removes an electrode array located on or below the dura mater by elevating a portion of skull bone. This procedure involves accessing intracranial space through a craniotomy or bone flap to explant an implanted electrode array that lies on the cortical surface or in the subdural space.

Service type: Neurosurgical explantation of intracranial electrode array
-
Typical site of service: Hospital operating room or ambulatory surgical center with neurosurgical capabilities

Clinical & Coding Specifications
Clinical Context
A typical patient undergoing 61535 is an adult or pediatric neurosurgical patient who requires removal of a previously implanted subdural or epidural electrode array that lies on or beneath the dura mater. Common scenarios include explantation of temporary intracranial electrode grids or strips after invasive electroencephalographic monitoring for refractory epilepsy, or removal due to infection, device malfunction, or completion of diagnostic monitoring. The clinical workflow begins with preoperative evaluation (history, neurologic exam, review of intracranial monitoring data, neuroimaging to localize electrodes and assess bone flap and dural relationships), anesthesia evaluation, and informed consent. In the operating room the patient is positioned and the prior scalp incision and cranial bone flap are exposed. A portion of skull bone is elevated (craniotomy or reopening of prior craniotomy) to access the electrode array on or beneath the dura. The neurosurgeon carefully removes the electrode array, inspects the dura and brain surface, achieves hemostasis, and closes the dura and scalp. Postoperative care includes neurologic monitoring, pain control, wound care, and follow-up imaging or clinic visits. Typical site of service is an operating room within an acute care hospital or ambulatory surgery center when clinically appropriate. The service type is a neurosurgical operative procedure (invasive intracranial device removal).
