Summary & Overview
CPT 61534: Craniotomy for Resection of Epileptogenic Focus
CPT code 61534 denotes a neurosurgical craniotomy in which part of the skull bone flap is elevated to excise an epileptogenic focus—brain tissue responsible for generating seizures. This code specifically excludes the use of electrocorticography as part of the service. Nationally, procedures to treat medically refractory epilepsy are clinically significant because they can reduce seizure burden and improve quality of life, and they carry substantial resource use and payer coverage considerations.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical intent and typical settings, plus benchmarking and coverage context where available. The publication summarizes coding and billing considerations, common modifiers, and the procedural scope that differentiates this code from related neurosurgical codes.
This report provides: a clear description of the service represented by 61534; guidance on typical site of service; an outline of payers commonly involved in coverage decisions; and pointers to related clinical and billing topics.

Billing Code Overview
CPT code 61534 describes a neurosurgical procedure in which the surgeon elevates a portion of the skull bone flap to excise an epileptogenic focus, an area of brain tissue that generates seizure-causing electrical impulses. The description specifies that this service does not include the use of electrocorticography.
-
Service type: Open intracranial neurosurgical resection of an epileptogenic focus (craniotomy with focal cortical resection)
-
Typical site of service: Inpatient or outpatient hospital operating room (neurosurgery suite) where craniotomy and brain resection procedures are performed
Clinical & Coding Specifications
Clinical Context
A 28-year-old patient with medically refractory focal epilepsy localized to the left temporal lobe by preoperative evaluation (video-EEG monitoring, MRI showing mesial temporal sclerosis, and neuropsychological testing) is scheduled for an open craniotomy and resection of the epileptogenic focus. The typical clinical workflow includes preoperative surgical consent and counseling, anesthesia evaluation, intraoperative neuronavigation to localize the lesion, a craniotomy with elevation of a skull bone flap, cortical exposure and resection of the epileptogenic tissue without intraoperative electrocorticography, hemostasis, and closure with replacement or management of the bone flap. Postoperative management includes neurologic monitoring in a post-anesthesia care unit or neurologic intensive care unit, pain control, antiseizure medication management, imaging (postoperative CT or MRI as indicated), and discharge planning with outpatient neurology follow-up for seizure control and rehabilitation as needed.
