Mine is not :(
I called today, and while they're aware of the change, they're not sure how it will affect tricare patients. Their other metlife patients have the ppo plan.
Also, my cleaning is literally a week after the change. But, due to the tricare apparently very literal once every 6 months rule, I can't schedule it for the end of April to make sure I can see my preferred dentist before the switch. They're going to call me back in April to let me know how it's all going to shake out since they seem almost as in the dark as I was. How is it that the only notification I've had about the switch was from this board?
