What the code means
For the purposes of the Health Care Provider Taxonomy, a contractor is limited to individuals who do construction or mechanical work to modify a patient's environment to accommodate a health condition. Contractors perform projects including, but not limited to, building wheelchair ramps, widening doorways, modifying personal vehicles, and making other improvements for patient access and movement. This code has no relation to a provider's employment status.

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.

Who registers under this code
8,214 of these are people and 1,531 are organisations, so 16% of the code is businesses rather than clinicians. Half of them had registered by 2014, and 2,533 registered in the last five years, 26% 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.
