What the code means
Early intervention services are an effective way to address the needs of infants and toddlers who have developmental delays or disabilities. The services are made available through a federal law known as the Individuals with Disabilities Education Act (IDEA). IDEA provides states and territories with specific requirements for providing early intervention services to infants and toddlers with special needs. In turn, each state and territory develops its own policies for carrying out IDEA and its requirements. Broadly speaking, early intervention services are special services for eligible infants and toddlers and their families. These services are designed to identify and meet children's needs in five developmental areas. These areas are: physical development, cognitive development, communication, social or emotional development, and adaptive development.

Who registers under this code
3,376 of these are people and 5,848 are organisations, so 63% of the code is businesses rather than clinicians. Half of them had registered by 2016, and 2,556 registered in the last five years, 28% 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.
