What the code means

A supplier that provides one or more of the following portable services, including but not limited to, x-ray, electrocardiogram (EKG), long-term EKG (Holter Monitor), bone densitometry, sonography, and other imaging services in accordance with all state and federal requirements, under the general supervision of a qualified physician. All necessary resources are transported to the patient's location where the services are performed.

Definition quoted verbatim from the NUCC Health Care Provider Taxonomy code set, version 25.1. Not paraphrased.

Where they are

Counted by practice location, not by mailing address or by licence state. A provider practising across a state line is counted where they practise.

Showing the 15 largest of 49 states with at least one.

Who registers under this code

36 of these are people and 1,284 are organisations, so 97% of the code is businesses rather than clinicians. Half of them had registered by 2012, and 222 registered in the last five years, 17% 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.

What else they list

Providers whose primary code is Portable X-ray and/or Other Portable Diagnostic Imaging Supplier most often carry these secondary taxonomies as well. This is the closest thing the registry has to a map of which specialties overlap in practice, and it is not published anywhere else.

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.
