When calling about the status of a bill, first contact Rising Medical Solutions (RMS) at 866-274-7464.  If you need further assistance, you can call MSF’s Medical Auditors at 406-495-5011.  Please give RMS the maximum 30 days processing time before calling about payment status. However, if you do have payment issues, it is best to bring them to our attention in a timely manner. An extensive list of payments can be time consuming to reconcile.
