I live in NJ and was rear ended. I had very severe body aches and was disoriented, so I was taken to the hospital to be checked out. I do not have ins and was under the impression the cost would be taken care of by the auto ins. But I just got a letter in my email from Geico requesting my health ins information, which I do not have. Why is that and what should I do? Please help
