Cost for eating disorder clinic?

My daughter was currently diagnosed with anorexia. the doctor gave her a few weeks to atleast show signs of recovery but all she has done is lose more weight. Now he has given her until the end of the week to gain atleast some weight, and if not he has said it is mandatory that she be sent to an impatient clinic due to serious health problems. My question is, how much would the cost be to keep her there for about 2 weeks to a month? I am in the military and i am not sure if TRICARE will cover all costs or if i will have to pay it all or part of it? If i do have to pay part how much would that be? If it is of any help, the clinic she will be attending is sheppard pratt. I would very much appreciate quick answers, and personal experiences similar to this would also be very much appreciated. Thank you
