This is identical to what had happened in my case, the patient was my son who had fractured his arm. Had taken him to Stanford Emergency, he got a a cast and a really cheap sling. Received a bill from a Texas based company, don't remember the name, for about $200-$300, for the sling. Looked online, there were bunch of BBB reviews about this, including about calling them where the issue was settled. Same sling on Alibaba.com was $1-$2. I called them up. I was told we were out-of-network for the sling, even though Stanford hospital was in-network. However, since we were in CA, we are kinda protected if we don't know this (in/out of network) in an emergency room. I had the option of asking Stanford and insurance company to refile, or pay them $20 (from original invoice of $200-$300). I paid them $20 to settle the claim.
