Common questions
Why does Labwest have 9 NPIs?
An organization may obtain more than one Type 2 NPI, for example for separate locations or units that bill on their own. Labwest's NPIs list practice locations in 8 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.
