How does an EFMP denial and reassignment work in Germany?

I just recently came up on orders to Germany next year, and I seriously couldnt be more excited about it! I am currently going through the EFMP process since my wife has certain health issues (mild asthma, PCOS), I learned today that if where I am going (Grafenwoehr) dosent have the nessecitites to tend to my wifes medical needs, that i may be re assigned to a different assignment that DOES have what she requires. Now the question here is, and im sorry if this is a really stupid question but I cant seem to find an answer for it...Will they try and re assign me to a different part of Germany? Or will that be completely out of the question? Right now I am trying to get all the info I need before I PCS. Any info that anyone can help me with this issue would be greatly appreciated.
