Received an estimate for elective surgery (full conversation was recorded). When bill came, it was dramatically higher (70%). I would not have agreed for this surgery if they had been transparent with costs. Wildly misleading. Discussed with billing department and patient relations with no proper resolution.

Currently in process of contacting BBB and filing a formal grievance to hospital through insurance carrier. Any suggestions for contacting medical or hospital boards would be greatly appreciated.

Note: will provide further updates here moving forward.
