What the code means
A Dietetic Technician, Registered (DTR)/Nutrition and Dietetics Technician, Registered (NDTR) is an individual holding a nationally protected title issued by the Commission on Dietetic Registration (CDR) to qualified individuals who obtain an associate's degree or higher and successfully complete a sliding set of academic, examination, and practice requirements accredited by the Accreditation Council for Education in Nutrition and Dietetics (ACEND) or established by CDR, the nature of which are dependent upon the level of academic degree obtained. The scope of practice of the NDTR focuses on food, nutrition, and dietetics practice, as well as related services. NDTRs work under the supervision of a Registered Dietitian Nutritionist (RDN) when in direct patient/client nutrition care, and may work independently in providing general nutrition education to healthy populations. Patient/client populations include individuals receiving individualized care who have medical conditions or diseases, as well as at-risk individuals receiving personalized nutrition guidance as part of preventive health care.

Who registers under this code
273 of these are people and 16 are organisations, so 6% of the code is businesses rather than clinicians. Half of them had registered by 2019, and 87 registered in the last five years, 30% of the current population.
That is close to the pace of the registry as a whole.
Where the practices are
By practice-location city. City counts are noisier than state counts, because a large employer files one address for many providers.

Looking up a specific provider
These counts come from the monthly NPPES file. To check one provider, use their NPI: the lookup reads the live registry and shows whether the identifier is still active, which the monthly file cannot tell you about the last few weeks.
