TriCare Prime anyone

Hey Has anyone used tricare and another insurance.  We have tricare as our secondary.  What did it require you submit for approval? Thanks for any input!

I used tricare remote and after my deductible they paid everything. I was in the hosp formy surgery and 2 times after and it was nice knowing they took care of it. When we first got it we had to use them as are secondary,but beens it was cheaper than what my husband had at work ,we just have it...

I have tricare prim they paid for everything thank God it was easy ,went to pcm & they ref me to a dr & had RYN
