<prompt> Human: Title says it all.I just started going to a physical therapist who recently broke contract with a big insurance company.They said that in network, the insurance company wasnt paying them much.To offset this, they have started billing out of network patients their would be in network rate, and write off the remaining costs.I spoke to them and asked if Id be responsible for anything over the copay Id usually have to pay for in network office and they verball guarenteed me that I wouldnt. The billing specialist even told me to ignore the EOB that my insurance company will provide me and just trust that they will only bill my the small in network benefit price.I spoke to the owner, and pressed for this in writing, but was just given more verbal guarantee and agreements.What the heck is going on? I feel that they are genuine, but at the same time nothing is protecting me from them charging me more for no reason. Ive also been told that what they are doing is against insurance law.Does anyone have any insight, advice on this particular situation. Its a shame because I feel Im getting good care. Im thinking about cancelling the rest of my sessions before the bills really start stacking up.  <response>: The fact that theyre not willing to give you this in writing would be enough of a red flag for me. Dont do it.
