Summary & Overview
CPT 61697: Intracranial Aneurysm Repair, Internal Carotid Circulation
CPT code 61697 denotes an intracranial surgical technique to repair a complex aneurysm in the internal carotid circulation, typically performed after or to treat a subarachnoid hemorrhage. This procedure represents high-acuity neurosurgical intervention with substantial clinical and resource implications across the US health system: it involves specialized surgical teams, advanced intraoperative monitoring, and postoperative critical care. Nationally, coverage and payment for complex intracranial aneurysm repair influence hospital resource allocation, neurosurgical service capacity, and patient access to definitive care.
Key payers discussed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context and service setting for CPT code 61697, plus an overview of the types of benchmarks and policy considerations typically associated with high-acuity neurosurgical CPT codes. The publication summarizes common payer coverage patterns, utilization benchmarks, and recent policy updates that affect hospital reimbursement and prior authorization practices. It also provides clinical context about indications and expected care pathways tied to this procedure.
Where specific payer policies, utilization metrics, or coding adjacencies are not present in the input, the text notes that data are not available in the input and focuses on universally applicable clinical and billing considerations for CPT code 61697.
Billing Code Overview
CPT code 61697 describes an intracranial surgical repair of a complex aneurysm in the internal carotid circulation. The procedure addresses an abnormal dilation or widening of a cerebral blood vessel and is used to treat aneurysms that have caused a subarachnoid hemorrhage.
Service Type: Intracranial surgical aneurysm repair
Typical Site of Service: Inpatient acute care hospital or specialized neurosurgical center (operating room)
Clinical & Coding Specifications
Clinical Context
A 58-year-old female presents to the emergency department with sudden severe headache, photophobia, and nuchal rigidity. Head CT demonstrates subarachnoid hemorrhage, and CT angiography identifies a complex saccular aneurysm of the cavernous segment of the internal carotid artery with irregular neck morphology and daughter sacs. Neurosurgery and neurointerventional teams evaluate the patient and elect for an open intracranial surgical repair due to aneurysm complexity and morphology not amenable to endovascular coiling alone. The clinical workflow includes preoperative neurological assessment, informed consent documenting risks of intracranial surgery and potential need for adjunctive procedures, preoperative imaging review (CTA/DSA), general anesthesia with neurophysiologic monitoring, microsurgical exposure of the internal carotid circulation, aneurysm clipping or reconstruction, intraoperative angiography or Doppler to confirm flow, postoperative ICU monitoring for vasospasm and neurologic deficits, and follow-up vascular imaging.
