Ok so how it works: I pay him each session out of pocket-full session price. In June I started my insurance coverage-and it includes therapy. T does not bill for insurance-it's all out of pocket. So in order for me to get reimbursed-I need a certain criteria from him in the form of the invoice (with DX info and service and his tax code) so I'm the one getting screwed out of money when he doesn't give me the info I need to file the claim.
