What the code means
Electrodiagnostic medicine is the medical subspecialty that applies neurophysiologic techniques to diagnose, evaluate, and treat patients with impairments of the neurologic, neuromuscular, and/or muscular systems. Qualified physicians are trained in performing electrophysiological testing and interpretation of the test data. They require knowledge in anatomy, physiology, kinesiology, histology, and pathology of the brain, spinal cord, autonomic nerves, cranial nerves, peripheral nerves, neuromuscular junction, and muscles. They must know clinical features and treatment of diseases of the central, peripheral, and autonomic nervous systems, as well as those of neuromuscular junction and muscle. Physicians also require special knowledge about electric signal processing, including waveform analysis, electronics and instrumentation, stimulation and recording equipment, and statistics.

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
17 of these are people and 376 are organisations, so 96% of the code is businesses rather than clinicians. Half of them had registered by 2018, and 99 registered in the last five years, 25% 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.
