I came in due to a infected toe, I waited for half an hour before being seen them when I was all they did was poke it and almost cut the infected part off but told me to see a specialist and sent me home with a $457 bill which I presented my insurance to them and they said right to my face I was covered but later that month I got a bill in the mail saying since they didn't send enough info to my insurance the bill defaulted onto me, this happened in November and I've called multiple times and every time the same response I get is "don't worry its taken care of you won't get another bill" 4 months later (today) I get a bill double the original. I just finished school last January and currently still am looking for a job I can't afford to pay nearly $1000 because either someone lied to me or the staff is too stupid to send the right info or read and tell me I'm not covered.
What a joke this hospital only cares about money and not helping people
