Checking an organization

  1. Match the NPI to the exact location you will visit or bill; each location can have its own.
  2. Confirm the business entity with the secretary of state.
  3. Check the HHS-OIG exclusion list for the organization and its owners.
  4. Verify each clinician you will see on their own record and with the state license search.

Common questions

Why does Hillsides have 13 NPIs?

An organization may obtain more than one Type 2 NPI, for example for separate locations or units that bill on their own. Hillsides's NPIs list practice locations in 7 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.
