My question involves a consumer law issue in the State of: Texas

My husband had some dental work done and the insurance lady in the office refused to file his insurance. I had to get pretty forceful but she finally did file the insurance; however, when she did the charges she submitted were much higher than what she had originally billed and what was originally on the Treatment Plan that my husband agreed to pay. I told the insurance this and they said there was nothing they could do.

Now she has submitted additional charges for services that have not even been scheduled yet, and for charges that were never authorized to be done. I believe she has also double billed several items under different names of services. Again, my insurance paid the claim and now my yearly limit has been exhausted.

He had to also see a periodontist and now the insurance won't pay at all on that visit since she has fraudulently filed this claim and the insurance paid the first dentist for services not yet completed.

It would seem my insurance doesn't care, so what agencies can I turn her and my insurance company into? You would think my insurance would want to stop the fraud, especially from a dentist who is in their preferred provider network.

Thank you for any advice you can give.
