Common questions

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.

Which Chicago NPI should I use?

Ask the office which NPI it bills under; all 21 Chicago NPIs are registered under the same name.
