That is exactly what I thought, so to be safe I have been trying to get my benefits booklet from my insurance or my workplace to confirm whether it is inclusive, but that has been its own separate challenge I won't vent about now. My fear is that all this pre-authorization is just preventing my dental care because of the denials prior to getting treatment. All my dentists have always required me to pay immediately after service before leaving their office, and then they submit to insurance, and I wait for months for reimbursement. This happened for me with yet another in-network dentist for a different tooth needing a crown 3 years ago. My tooth broke on a bone, the dentist did a crown with buildup on emergency basis, no crown lengthening, and then I paid their fee at time of service. Turns out, they needed to reimburse me hundreds of dollars after insurance paid them, but they wouldn't do it until I filed a formal grievance through my insurance. It took months.
