Onsite Inpatient Care Manager

Hello,
Is anyone familiar with an Onsite Inpatient Care Manager position?? They explained to me that you would go to different hospitals and do UR review and write reports at home. It is a managed care company. Do you think they reimburse for mileage and gas??? I have not done case management and it sounds very similar to me.

Does anyone have any insight to this type of position?? What is a typical day like??
