<prompt> Human: Doctors office either lied or was misinformed when they told me not in writing that I would have no out-of-pocket cost for a procedure. He then sent me a bill for the cost that my insurance didnt pay. Do I have any recourse? Sorry if this is the wrong sub, you guys always have the best advice.Edit: Thanks for all the advice! Youve given me a few things to look into.Assistant: The dentist used a fancy filling for a cavity, my insurance only covers the regular filling, which my dentist didnt have. Dentist never told me about this until he sent the bill, I have this part in writing in a letter he included.  <response>: the fancy white filling is totally worth the money over the regular silver. my insurance is the same way So I just pay the difference
