Shot down in Kabul and now asked to pay at private hospital, Why isn't military paying?

Fiance was shot down Sunday May 15, 2011 in route to Kabul, Afghanistan while he was transporting soldiers. He survived with extensive leg injuries. He was transported from Bagram to an undisclosed private hospital on the outskirts of Afghan. It’s bad enough he is in dire pain and facing the lost of his long time friend who was co-piloting, the hospital is now asking him for $700 US dollars for quality care and refers to it as “family token”. (in addition to what military is paying) Has anyone heard of such a practice? We can only come up with $500. I am desperate and feel horrible enough that he’s there all alone. Any insight would be greatly appreciated.
