I think it's always best to take records with you. I moved back in Nov and made a few efforts to call ahead but never got any return calls. I *think* you may need to be in the country to get anywhere.
I am fortunate to live in a state that has systems in place to ensure that no child goes without health care. As such, because I am still job hunting, I was able to get us insured through them. But we'll have cover through my husband's job come April.
Not sure if Wisconsin has a similar program but it's worth looking at.
