delta dentist

I chose to upgrade to a "Special" dental plan of Delta from the "Standard" dental plan, both of which I have through my employer. Before upgrading, I researched how much of a crown the Special plan would cover. According to the info sheet my HR department gave me, 90% was to be covered for a crown provided by a PPO Network Dentist, and if it was a Non-PPO Network Dentist, Delta would cover only 60%. I asked the dentist if they were a member of Delta, and they said yes. (Since they had not been able to give me an idea of how much the crown would cost me, I made the effort to do this research) I then told the dental office it was 90%. But it turns out Delta only covered 60%. I only learned after that there are different kinds of Delta members (my dentist was member, but not a member of "Delta Premiere"). If a provider is a member of Delta, don't most people understand it to mean they are therefore part of the PPO network? Very misleading. Who can I show is responsible for these fees?

I have Delta Dental insurance and i have white spots that my dentist wants to bleach my teeth for. So my question is, will my insurance cover it, and what is it?

I was told by the oral surgen office that they would decifer who would pay for more coverage dental or medical insurance. Come to find out they went with my medical insurance. They told me that my balance was $410, and insurance would pay the rest. I paid that. Then I get a bill saying that the claim was denied due to not being refered by my primary care physcian, and I owe the remainder of the balance: $2400.00. What are my options. I was refered by my delta dental dentist, do I demand that they chase them down. I am not paying this. My teeth were not hurting, but though that it would be a good preventitive measure.
