Business ProfileforKindle dentistry

On my first visit, the front desk lady said my insurance was not active, so I pulled up my insurance information on my phone proving it was active and she says she will call again to verify. She calls, verifies that it is active and says oops, I must have misheard the first time I called. I went in for a maxillary partial denture that I needed and I asked if I prepaid for it, could they still submit a claim to my insurance company and would I get a refund on the amount my insurance company pays, the lady said yes, so I prepay close to $600. I wait for a month and I get no calls, no emails, nothing. So I called my insurance company and asked a representative if my dentist submitted a claim and they tell me no. I then asked if my insurance benefits cover a maxillary partial denture and the rep said yes, 50%, then I asked can my dentist still submit a claim for a procedure already done and she says yes, dentist has a year to submit a claim from the date of the procedure. The next day I go to the dental office and spoke to the billing lady and she lied to me saying that my insurance doesnt cover partial dentures. When I told her yes they do, I spoke to a rep from my insurance company, she lied again and said oh, well, I meant they wont take a claim for a procedure that has already been done. I said Yes they will, the rep said you have a year to send a claim from the date of the procedure. She responded with Oh, you actually spoke to someone at your insurance company? I said yes. So she grabs a claim form and fills it partially out in front of me and says she will submit it that day. 4 weeks later I get a letter from my insurance company saying they are denying the claim because they dont cover miscellaneous procedures. I looked at what *** billing code that lady at the dental office put on the claim and its a code for a miscellaneous procedure, not the correct code for a maxillary partial denture. She put the incorrect billing code on the insurance claim.
