MarthaMFI:is there a time limit on back billing in the US?
A person is not excused if they have not recieved a bill. However, it is difficult in these cases where you don't know you had one. I believe medical bills can remain on your credit history and the company can attempt to recieve payment on it for ten years.
So the clock is ticking against them and here I am willing to pay...I really don't understand why they aren't making an effort to send me what I need.
