15 Miss. Code R. § 16-1-82.14.4
Each private review agent's staff shall identify themselves by name and by the name of their organization and, for on-site reviews, should carry picture identification and the private review agent company identification card. On-site reviews should, whenever possible, be scheduled at least one business day in advance with the appropriate hospital contact. Private review agents shall agree, if so requested, that the medical records remain available in designated areas during the on-site review and that reasonable hospital administrative procedures shall be followed by on-site review staff so as to not disrupt hospital operations or patient care. Such procedures, however, should not limit the ability of the private review agent to efficiently conduct the necessary review on behalf of the patient's health benefit plan.
