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.

Statute and Regulation Details
Licensure (or Certification) by Endorsement of RDN Credential/Exemptions
324.210. Qualifications of applicant for licensure — examination required, exception.
1. An applicant for licensure as a dietitian shall be at least twenty-one years of age.
2. Each applicant shall furnish evidence to the committee that: (1) The applicant has completed a didactic program in dietetics which is approved or accredited by the Accreditation Council for Education in Nutrition and Dietetics and a minimum of a baccalaureate degree from an acceptable educational institution accredited by a regional accrediting body or accredited by an accrediting body which has been approved by the United States Department of Education. Applicants who have obtained their education outside of the United States and its territories must have their academic degrees validated as equivalent to the baccalaureate or master's degree conferred by a regionally accredited college or university in the United States. Validation of a foreign degree does not eliminate the need for a verification statement of completion of a didactic program in dietetics;
(2) The applicant has completed a supervised practice requirement from an institution that is certified by a nationally recognized professional organization as having a dietetics specialty or who meets criteria for dietetics education established by the committee. The committee may specify those professional organization certifications which are to be recognized and may set standards for education training and experience required for those without such specialty certification to become dietitians.
3. The applicant shall successfully pass an examination as determined by the committee and possess a current registration with the Commission on Dietetic Registration. The committee may waive the examination requirement and grant licensure to an applicant for a license as a dietitian who presents satisfactory evidence to the committee of current registration as a dietitian with the commission on dietetic registration.
Licensure by Reciprocity for Other Counties Only
324.215. Issuance of license, when — reciprocity — reexamination, limitations.
1. The committee shall issue a license to each candidate who files an application and pays the fee as required by the provisions of sections 324.200 to 324.225 and who furnishes evidence satisfactory to the committee that the candidate has complied with the provisions of section 324.210 or with the provisions of subsection 2 of this section.
2. The committee may issue a license to any dietitian who has a valid current license to practice dietetics or medical nutrition therapy in another country, provided that such person is licensed in a country whose requirements for licensure are substantially equal to, or greater than, the requirements for licensure of dietitians in Missouri at the time the applicant applies for licensure.
3. The committee may not allow any person to sit for the examination for licensure as a dietitian in this state who has failed the examination as approved by the committee three times, until the applicant submits evidence of satisfactory completion of additional course work or experience and has been approved by the committee for reexamination.
