Established physician-patient relationship means a relationship between a physician and a patient that is for the purpose of maintaining the patient's well-being. At a minimum, this relationship is established by an interactive encounter between patient and physician involving an appropriate history and physical and/or mental status examination sufficient to make a diagnosis and to provide, prescribe or recommend treatment, with the informed consent from the patient and availability of the physician or coverage for the patient for appropriate follow-up care. A medical record must be generated by the encounter.
