Aspen Dental

I went to Aspen Dental on 8/15/23. I need on emergency root canal and crown. I know exactly how my insurance works, what is covered, how the contract between my insurance and in-network providers works and have knowledge of medical coding and billing. I have no deductibles or copays for emergency and regular dental care. I have special needs disability insurance. I should have no problem getting my emergency taken care of with no out of pocket costs. They said the entire treatment would cost $8900 and I would have to pay $5000 out of pocket upfront before insurance even goes through. They are bill balancing and that is fraud and illegal.
