One of the biggest challenges I faced at my previous job was we had a specific client that our cases went to litigation, was resolved and settled before trial, and we had a list of all reported medical bills and records to us that we had since settled with the medical professionals and their billing offices, and within, I would say, a month or two later, we were contacted again by this client to let us know that there was one to two outstanding bills that we had not been aware of, we had not been made aware of, and obviously everything had been taken care of, and so the client was semi-disappointed to deal with that. So what I went ahead and did, obviously, was offer to go ahead and reach out to those billing departments and to negotiate down that bill for them, and so that's what I did. I went ahead and contacted the billing office, negotiated it down significantly, re-contacted back the client to let them know I was successful in doing so, and they were really grateful that I was able to do that, since technically they were no longer an active client of ours, and so they were really appreciative of that, even though their case had been closed for two months.
