<prompt> Human: This is a follow up to the question I asked one week ago.Long story short, I went to an appointment in Mount Sinai six months ago and it went through my university students health care. However, I never got the bill so I had to call Mount Sinai multiple times until I got an answer.According to them, they are confused whether I have insurance or not. My student insurance ended on 820 while I got my Explanation of Benefits on 53. Since I had my appointment on 412, I told them that my insurance should already paid their part. They told me they would recheck with the billing department.Question is, am I right? If I got my explanation of benefits letter, does that mean insurance had already taken their responsibility? I would probably call insurance tomorrow.  <response>: If I got my explanation of benefits letter, does that mean insurance had already taken their responsibility?Yes, they should have.
