St. Elizabeth's Medical Center a Steward Family Hospital

The medical center and the medical group have two different billing systems. I was without insurance and needed a follow-up post-surgery. I asked for a price before the follow up with the medical group and they said the total for the post-surgery follow-up appointment was $200 and I accepted then scheduled the appointment. I paid the $200 when I arrived for the appointment. The medical group and the hospital then sent me separate bills, both for approximately $450, which would make it an $1,100 follow-up appointment. Eventually, the medical group admitted to their mistake and apologized. The medical center (St. Elizabeth's) has been calling me non-stop and sending me letters and is now threatening to send it to collections. I answered many of the phones calls and told them it was a mistake and to follow-up with the medical group. They refuse to talk to the medical group and insisted on a price-drop because I did not have insurance. They will not admit their mistake or talk to the medical group for the $465.10 bill more than tripling the initial price given to me. This was a follow-up with the doctor seeing me for under 10 minutes and the bills sent to me initially totaled $1,100.
