Check with your insurance directly rather than just taking the nurse’s word for it.

Thanks. I've tried calling them a few times and so far have been unable to get anyone on their phone...and their website tells me to contact Facility A, which is the only option listed...so I kind of feel like this is where the doctor's office got their info.

BUT I did some more searching through their list of providers, and it turns out their network includes a medical center specializing in ASD at one of the universities here, so I'm going to try them next.
