What the code means
A Radiology Practitioner Assistant (RPA) is a health professional certified as a registered radiographer with the American Registry of Radiologic Technologists (ARRT) and, in addition, is credentialed to provide primary radiology health care with radiologist supervision. Radiology Practitioner Assistants are qualified by graduation from an educational program recognized by the Board of Directors of athe Certification Board for Radiology Practitioner Assistants (CBRPA) and certified by the CBRPA. Within the Radiologist/RPA relationship, Radiology Practitioner Assistants exercise autonomy in decision making in the role of a primary caregiver with regard to patient assessment, patient management and in providing a broad range of radiology diagnostic and interventional services. The clinical role of the Radiology Practitioner Assistant includes primary and specialty care in radiology practice settings in rural and urban areas.

Where they are

Who registers under this code
389 of these are people and 6 are organisations, so 2% of the code is businesses rather than clinicians. Half of them had registered by 2015, and 147 registered in the last five years, 37% 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.
