Summary & Overview
CPT 61540: Non‑temporal Brain Lobectomy via Craniotomy
CPT code 61540 denotes a neurosurgical craniotomy with partial or total removal of a brain lobe other than the temporal lobe (for example, frontal, parietal, or occipital lobectomy). This procedure is performed to remove diseased or damaged brain tissue for indications such as refractory seizures, tumors, or focal structural lesions. Nationally, this code represents a high‑acuity invasive surgical service with implications for hospital resource use, perioperative care, and specialist credentialing.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical site of service, and the service type tied to the code. The publication provides benchmarking and utilization context where available, summarizes relevant policy and coverage considerations affecting authorization and facility-level billing, and clarifies common modifier and service-line interactions when present. The content is tailored for hospital administrators, neurosurgeons, and revenue cycle professionals seeking a national perspective on coding, billing, and operational implications for CPT code 61540. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 61540 describes a neurosurgical procedure in which the provider partially or totally removes a brain lobe other than the temporal lobe — for example, the frontal, parietal, or occipital lobe — through an elevated portion of skull bone. This procedure is a craniotomy with lobectomy (non‑temporal) performed to address structural brain pathology.
Service Type: Neurosurgical lobectomy (non‑temporal)
Typical Site of Service: Inpatient or outpatient hospital operating room (surgical suite)
Clinical & Coding Specifications
Clinical Context
A typical patient is a 28–55-year-old adult presenting with drug-resistant focal epilepsy originating outside the temporal lobe (for example, a frontal lobe seizure focus), a symptomatic cortical lesion (e.g., low-grade glioma), or a large arteriovenous malformation producing seizures or focal neurological deficits. Preoperative evaluation includes neurologic exam, MRI brain with and without contrast, scalp and/or invasive EEG monitoring, functional MRI and neuropsychological testing, and multidisciplinary case review with neurosurgery, neurology, and anesthesiology. The operative workflow begins with general anesthesia, neuronavigation setup, and a craniotomy over the involved lobe. The surgeon performs a partial or total lobectomy of a non‑temporal lobe (frontal, parietal, or occipital) through an elevated skull bone flap, routinely employing intraoperative neurophysiologic monitoring, awake mapping when indicated, and hemostatic and reconstructive techniques before closure. Postoperative care occurs in a neurosurgical intermediate care or intensive care unit with serial neurologic checks, imaging (CT or MRI) to exclude hemorrhage, pain control, anticonvulsant management, and early mobilization. Discharge planning includes outpatient follow-up with neurosurgery and neurology for seizure management, pathology review, and rehabilitation as needed.
