...get? my dentist office to submit certain procedure charges to certain insurances? since each plan covers something different that i need done, and vice versa?

If the corresponding plan covers the corresponding procedures you need done, just hand them all your insurance cards or proof of insurance and let them deal with the billing...they pay people to do that

If you have hit the dentist lottery and actually have a secretary that knows how to bill correctly- you are right- all three insurances are liable to pay for the procedures that will be done--but before you go to the dentist- please read over ALL THE RESTRICTIONS listed in those little clauses you can barely read--and if there are none that interfere with your dental plan and payment plan with the companies- make sure your DENTIST is aware of your 3 insurances so he can oversee the correct coding and billing to each insurance..........*you have also watch to make sure he doesn't bill all 3 for the same procedures..........good luck and happy smiling.
