Common questions

Why does Massachusetts General Hospital have 34 NPIs?

An organization may obtain more than one Type 2 NPI, for example for separate locations or units that bill on their own. Massachusetts General Hospital's NPIs list practice locations in 11 cities.

Is an organization NPI a license?
