Medical nutrition therapy is a medical treatment. Like other non-physician practitioners providing medical treatments, registered dietitian nutritionists generally can practice MNT because of licensure and certification laws, which provide authority for RDNs to provide this medical service. It is with this understanding that the Academy strongly recommends — unless there is an applicable exception or exemption or a state does not provide for licensure or certification requirements — practitioners hold licensure or certification in all states where the practitioner's clients or patients are located when services are provided.
