My wife has dental insurance with Delta Dental. She had a procedure at Lubbock Dental Care, paid her co-pay with cash, and when we signed out they demanded an extra $ 670.00. We said, " what about the insurance?" We were told Delta had a 2 year waiting period. We told them the policy has been active for 5. Then they said they filed it but Delta refused to cover the claim. I had no choice but to give them a credit card, so they wouldn't call the police on us. We contacted Delta, and were told Lubbock Dental care never filed a claim. A week later Delta informed us that Lubbock Dental Care filed a claim and it was paid. So, Lubbock Dental Care was paid twice for the same thing, and lied about it. This is insurance fraud! Big shakedown by front office staff. Delta Dental Insurance is a federal program, so I reported this to Delta. I can see a dentist losing his license, and/or someone going to jail for this.
