Common questions

Why does Commonwealth Of Massachusetts have 38 NPIs?

An organization may obtain more than one Type 2 NPI, for example for separate locations or units that bill on their own. Commonwealth Of Massachusetts's NPIs list practice locations in 27 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.
