  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 San Mateo County have 29 NPIs?

An organization may obtain more than one Type 2 NPI, for example for separate locations or units that bill on their own. San Mateo County's NPIs list practice locations in 12 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.
