I have dental insurance through WellPoint Dental Services. I needed a dental procedure and my dentist filed, and I received an approval / precertification from WellPoint in the mail. He said the insurance would pay $ 204 of the procedure. I had the procedure 4/25/2007. I paid my dentist in full (this is what he does), and have tried to collect the $ 204 since. I called the insurance co and am repeatedly told that he was going on. I have written 2 letters with a copy of prior authorization to the address on my card and have received no response. On 7/18/2997, said a rep that it had been misfiled, but it would immediately be sent to claims and that all necessary information was there. I have received no reply to my letters, no check. What should I do now? This procedure was $ 1000 and I was really the $ 204th Thanks for any help!
