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 Williston NPI should I use?

Ask the office which NPI it bills under; all 10 Williston NPIs are registered under the same name.
