What the code means
(1) An EPO is a form of PPO, in which patients must visit a caregiver that is specified on its panel of providers (is a participating provider). If a visit to an outside(not participating) provider is made the EPO offers very limited or no coverage for the medical service; (2) While similar to a PPO in that an EPO allows patients to go outside the network for care, if they do so in an EPO, they are required to pay the entire cost of care. An EPO differs from an HMO in that EPO physicians do not receive capitation but instead are reimbursed only for actual services provided; (3) An organization identical to a preferred provider organization except that persons enrolled in the plan are eligible to receive benefits only when they use the services of the contracting providers. No benefits are available when non-contracting providers are used, except in certain emergency situations.

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
99 of these are people and 2,176 are organisations, so 96% of the code is businesses rather than clinicians. Half of them had registered by 2011, and 142 registered in the last five years, 6% 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.
