OP here. Thanks for the recs for Todd Misura. He was at the top of my list to call. I'll have to check my OT benes again, but I'm sure this type of service was excluded. Gosh - not only do I have a high deductible plan ($3200), it won't cover the things I actually need for my child. (But that's a whole other topic.)
I do see I mistyped one of the therapist's names - it should be Rachael Makar, not Rachel Maka.
