yeah i called this morning, they said they dont know who the the bills are from and told to call the hospitals. I read in forums that it is under federal law for collection agencies to tell me who do i owe the charges to. 

Like nepali_american said, I am hoping this is a scam, but since this serious issue, I want to be 100% sure. What should I do to make sure this is a scam? check google for keywords? Should i just ignore them? Do I need to inform a credit bureu to make sure my credit is not messed up?
