Checking an organization
- Match the NPI to the exact location you will visit or bill; each location can have its own.

- Check the HHS-OIG exclusion list for the organization and its owners.
- Verify each clinician you will see on their own record and with the state license search.
Common questions
Why does Act IV have 5 NPIs?
An organization may obtain more than one Type 2 NPI, for example for separate locations or units that bill on their own. Act IV's NPIs list practice locations in 3 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.
