Common questions

Why does Psychological Services have 18 NPIs?

An organization may obtain more than one Type 2 NPI, for example for separate locations or units that bill on their own. Psychological Services's NPIs list practice locations in 18 cities.

Is an organization NPI a license?

No. An NPI identifies who bills. Facilities and the clinicians who work there are licensed separately by the state.
