Common questions

What does subpart mean?

The organization registered this NPI as a subpart: a part of the organization, such as a location, that bills under its own NPI.

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 Concord NPI should I use?

Ask the office which NPI it bills under; all 19 Concord NPIs are registered under the same name.
