After asking three times to make sure I was covered by their out-of-network rates, they assured me that it would not cost a dime out-of-pocket.
Result: I was asked to pay $1k. They checked the wrong billing codes (twice).
The kicker: I arrived at 3:30pm. She said that the appointment was scheduled for 3pm (it wasn't). She gave me two options: (1) re-schedule, (2) forego any and all anesthetic during the drilling/filling. Since I couldn't take additional time from work, I opted to go ahead without anesthetic. All so she could leave by 5:30 instead of 6pm.
Bravo, Dr. Tays. Bra ... vo.
