Summary & Overview
CPT 61682: Craniotomy for Resection of Complex Supratentorial AVM
CPT code 61682 denotes a neurosurgical craniotomy for resection of a complex supratentorial arteriovenous malformation (AVM). This code applies to operative treatment of AVMs larger than 3 cm or those with deep venous drainage or involvement of eloquent cortex areas such as sensorimotor, speech, or language regions. The code is clinically significant because it represents high-risk, resource-intensive neurosurgical care with implications for hospital resource use, postoperative monitoring, and specialty reimbursement.
Key payers referenced in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a national overview useful to hospital administrators, neurosurgeons, and billing professionals.
Readers will find: an explanation of the clinical context and surgical scope for 61682; typical sites of service and service type; common modifier practice and billing considerations summarized from input; and what information is available or missing for taxonomies, diagnoses, and related codes. The piece frames 61682 within national payer coverage patterns and operational implications without state-specific detail, offering concise context for clinical coding and administrative planning.
Billing Code Overview
CPT code 61682 describes a neurosurgical procedure that involves craniotomy with resection of a complex supratentorial arteriovenous malformation (AVM). The procedure removes a portion of the skull (craniotomy) to access and excise an AVM located in the supratentorial region of the brain — the area above the tentorium cerebelli that includes the cerebral hemispheres.
Service type: Neurosurgical operative procedure for complex intracranial AVM resection.
Typical site of service: Inpatient hospital operating room with postoperative inpatient care, given the complexity and intracranial nature of the procedure.
Data not available in the input for Associated Taxonomies, ICD-10 Diagnoses, and Related Codes.
Clinical & Coding Specifications
Clinical Context
A typical patient is a 38-year-old adult presenting with progressive headaches, focal seizures, or new focal neurologic deficits. Neuroimaging with MRI and cerebral angiography demonstrates a complex supratentorial arteriovenous malformation (AVM) greater than 3 cm in maximal diameter with deep venous drainage and cortical involvement near eloquent language or motor cortex. The multidisciplinary workflow includes evaluation by neurosurgery and neurointerventional teams, preoperative angiography for detailed vascular anatomy, discussion at a cerebrovascular conference, and planning for microsurgical resection. On the day of surgery the patient undergoes general endotracheal anesthesia, neuronavigation and intraoperative neuromonitoring are used because of proximity to eloquent cortex, a craniotomy is performed, and the AVM nidus is circumferentially dissected and resected with microsurgical techniques and hemostatic measures. Postoperative care involves ICU-level neurologic monitoring, repeat vascular imaging (CT angiography or digital subtraction angiography) to confirm complete resection, and rehabilitation as needed. Typical site of service is an inpatient hospital operating room with subsequent ICU stay for close neurologic observation.
