Tricare ?

I’m going to call tricare to figure it out but I was wondering if anyone looked on the website to see if a doctor was in network and it tells you the facility is not in network but the provider that only works at that facility and no where else and is employeed by the facility not self contracted is in network?

My little family has gotten hit very hard lately we had 5 hospital stays, an urgent care visit, roughly 10 clinic visits, 3 x rays, and countless lab draws in the last month and a half..... I’m terrified to start getting the bills if these places are out of network.
