Thermal Perfusion Probe for Monitoring Regional Cerebral Blood Flow

Aetna considers thermal perfusion probes for monitoring regional cerebral blood flow investigational and not a covered/medically necessary service, excluding their use for acute neurologic disorders (e.g., head injury, subarachnoid hemorrhage, post‑neurosurgery) and for the listed ICD‑10 codes. Key requirement: prospective randomized clinical outcome evidence demonstrating clinical benefit is lacking, so the technology remains experimental/investigational and non‑covered.
