What the code means
A health care professional who is specifically educated and trained to manage comprehensive orthotic patient care, including musculoskeletal and neuromuscular anomalies resulting from injuries or disease processes involving the lower extremity, upper extremity or spinal segment/s and positional deformation of the cranium. Orthotists assess specific patient needs, formulate an appropriate treatment plan, implement the treatment plan and provide follow-up care.

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
1,234 of these are people and 90 are organisations, so 7% of the code is businesses rather than clinicians. Half of them had registered by 2013, and 232 registered in the last five years, 18% 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.
