My fiance was receiving SSI, they kicked him off and claimed he was not bi polar. He is and has been hospitalized twice and was given Lithium. he has no medical coverage. it is all out of pocket. They issued a statement saying he owes about 10 grande. they took his tax return last year due to this. What steps should he take to fight this so he can at least not owe them back money? and possibly return to being on SSI? thank you.
