psoriasis
"annabamma-  you need to PROVE beyond a shadow of a doubt that her psoriasis is debilitating.  It must be SEVERE for them to cover the cost of the medicine.  Moderate just wont cut it, it didn't in my case.  I know its easier said than done but I let my skin get horrifically bad just to prove to my insurance that it should be covered.  TAKE PICTURES and see several dermatologists until one considers it a MAJOR problem.  Hope that helps."
