I have a large group of bills, all medical. 90 to be exact. some of it has changed hands multiple times. i have it setup on a spreadsheet. so i can sort the data by creditor, account number (which sometimes all they give you is a claim number and that just makes everything confusing) ......there are multiple claim numbers on an "account" number. i still can't make much sense of it. i know things are listed multiple times, some is out of SOL and i went through all my bills most of which doesn't have a service date and out of the ones that do, im not sure it is correct.
