<prompt> Human: I went to the ER Kaiser. Two weeks later I moved. I had mail forwarding in place starting a few days before I moved just to be sure I didnt miss anything. A few days after moving I went on vacation for three weeks, during which I had my mail held.A week into my vacation I also changed my address with Kaiser over the phone. I came home and got a bill from kaiser for the ER visit I now see that a portion of the amount said past due, but while plowing through my 3 weeks of mail unfortunately I missed this detail. I also think a bill must have been lost somehow because I dont have a first bill, only one that says past due. I mailed Kaiser a check immediately.They cashed it. Now exactly 2 months after going to the ER I just received a bill from a collection agency for the money I have already paid to Kaiser. Holy shit, that was fast. They couldnt call or something before sending it to collections??I am going to call Kaiser tomorrow when their billing department opens, but is there anything else I should be doing? Is there a way to get this fixed so it does not impact my credit? Am I supposed to pay the collections agency immediately it is not a large bill, I can pay it for a second time if I have to, or do I need to dispute it somehow?I am so happy this happened after my mortgage went through. I have heard many other reports of hospitals sending things to collections at the drop of a hat but this still caught me completely off guard. Thanks in advance for any advice!Update: I called Kaiser and they said they would take care of it since they can see it has been paid, but I only like 80 believe that they will actually fix it so I am going to also ask them to verify the debt using the I do not owe this debt version of the form letter linked below just to be sure. thanks Padmewan!Assistant: It does seem really fast to send you to collections.Are you a Kaiser member or is that just the ER you went to?Kaiser does a three part billing that makes no sence to any reasonable person. They bill you separately for hospital, lab, and professional. These bills dont always come together. Especially a lab bill. It is possible that you paid the bill you received in the mail and not one that got lost in the shuffle. If your a member you can check these online once you have an account set up. That being said dont trust that if online says you owe, that you really do owe. Kaiser never shows that you have paid anything even if you pay on their website. They will gladly show your balance until one day it is cleared.Im a member and a have a seperate health care savings account. I paid for a visit several months ago when I got an email. Then my wife paid when one of the paper bills came in because online we still had a balance. She then paid the balance in full online. So now kaiser has been paid twice plus a little more. That drained my HSA and I got a notification. Calling Kaiser was fruitless, but a month later they sent me checks for each over payment. Basically, Kaiser makes getting your ducks in a row difficult. You didnt help by changing addresses. Sending you to collections might have been an automatic computer thing. Human: I am a Kaiser member. I am sure that I paid the correct bill we checked this online, but it is true that my check only cleared a week ago, so perhaps this collection process had already been initiated at that point.When rereading the letter I received I noticed that it says Please be advised that the current creditor listed above and the original creditor are the same creditor. Maybe this means this is basically still a letter from Kaiser, and the debt has not been sold off? The letterhead is for USCB America.The letter also says that that I must resolve it within 40 days of the date of the letter which is a week ago, even though it came in the mail today in order to avoid having it show up on my credit report. It is great that I have time to pay it before they will report it, but then if I dispute it via certified mail because I have already paid am I eating into that time? I care more about my credit than paying this bill twice, which thankfully was by far the smaller of the two ER bills I have received so far.  <response>: I work for a similar collection and billing company. USCB is a collection agency but they do not own the debt they just receive a of what they recover for kaiser. if you call and been let then know what happened they will put it in a dispute status which will not allow them to report it to your credit report until the dispute is resolved. submit any documents you have showing it as paid i.e. check image from the bank and this should clear it right up.
