Last year (in April) I had the mystery bill from a local hospital I never went to (and posted about ithere) and then I had to fight with them to get them to submit the correct type of procedure they did to the my insurance. All the time I was getting bills saying I had to pay or they would report this to the credit bureaus and send this to a collection agency (basically threatening me).
Once they filed it properly my insurance had me pay a co-payment, which made no sense as it was part of the procedure done at a doctor's office. At that point I didn't care any more and paid it, happy to let it go. Now just two weeks ago I get a letter from the insurance saying I shouldn't have been required to make a copayment and they went and paid the hospital my $25 copayment.
Of course the hospital didn't send any reimbursement of the copayment. I knew that would happen, so again another call to the hospital this Wednesday where I get "Oh, you'd like the money back? Sure we can do that." however, what goes through my mind is to say "No, actually I like paying extra, don't you?" GRRRR.... I just say "yes", and leave it at that.
Funny how their systems work great one way and not the other. Ugh. Oh well, I guess I should be happy about the extra money.
