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.
