Disorders managed by sleep specialists include, but are not limited to, sleep related breathing disorders, insomnia, hypersomnias, circadian rhythm sleep disorders, parasomnias and sleep related movement disorders.

Who registers under this code
516 of these are people and 272 are organisations, so 35% of the code is businesses rather than clinicians. Half of them had registered by 2008, and 68 registered in the last five years, 9% of the current population.
That is a slow-growing code, which usually means an established field replacing retirements rather than expanding.
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.
