My wife and I just recently change our Insurance carrier from United to Aetna through my wife's work. My wife specifically asked the receptionist if this office was a in network provider for Aetna. She replied she they are an in-network provider. Now after 5 visits and they are stating that they never said that and now we are responsible for the office visits which mount up to over $500. The first visit was in July and we are just now getting this bill. My wife and I voiced our concerns to the Doctor and where not happy with the outcome. We are taking this to the next level. If you have had a similar situation please let us know how you formally filed a complaint.
