This is not a covered indication. If it's private insurance, you could get the medical director to draft up a letter to the insurance company explaining the benefits that the patient can receive. Usually once they see the money that could potentially be saved they should ok the treatment. If it is CMS you would just have to eat the cost. We've treated 3 pts at our facility with Idiopathic Sudden Sensorineural Hearing Loss and one pts private insurance gave us the auth for the treatment the other 2 (one CMS, one private), denied the it, so we ate the cost.
