I'll try to make a long story short. I had my wisdom teeth removed in January and paid a little oop that was the difference between what was pre-approved by my dental insurance. Fast forward 8 months and I am now getting bills from the dentist due to the insurance denying the claim. My insurance informed me that it was denied because it was not submitted until June. I understand that I agreed to pay anything not paid by the insurance but it was the dentist office that caused the claim to be denied. Is there anything I can do to fight the bills?
