Yes I have called great leaps as well in our area tricare is the only insurance accepted for ABA specialist. It's almost $600 just for the consult out of pocket and then depending on how any times a week and how long I could be spending almost that a week possibly. The CCAD is who diagnosed him and told I would have to pay out of pocket for ABA

Tricare is military insurance. Did you contact the places directly to ask if they accept your insurance? Sometimes places don't list any/all of the insurance plans they accept... but possibly are listing Tricare simply to let military families know they do accept it... (Sometimes it is SOOO hard to find places that accept tricare!!)

I find it hard to believe that ANY place (except on-base hospitals/doctors) would only accept TriCare, because tricare doesn't pay as much as a normal insurance company would.... which leads many places to STOP accepting it....which makes it hard to find places that do...haha.
