CPT code 61584 represents an orbitocranial (transorbital) surgical approach to the anterior cranial fossa for exposure of an extradural skull base lesion or defect. The procedure includes a suborbital ridge osteotomy and elevation of frontal and/or temporal lobes as needed, but does not include orbital exenteration. This code is relevant nationally for neurosurgery and craniofacial surgical practices managing skull base pathology where transorbital access is indicated.

Key payers considered in coverage and reimbursement contexts include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for when the approach is used, typical sites of service, and which payers commonly cover the service. The publication also summarizes benchmarking and policy-relevant considerations such as coding specificity, common modifiers (provided separately), and implications for hospital and ambulatory surgical center billing workflows.

The content provides clinicians, coding professionals, and policy analysts with the clinical definition of the service, payer landscape, and the kinds of benchmarks and policy updates to expect when managing claims for complex anterior skull base procedures using a transorbital approach.
