How NPI Lens uses the list
Every provider page checks its NPI against this file (OIG file of Oct 9, 2026). A record that carries the same NPI is shown as a match; a record without an NPI but with the same name and state is shown as a possible match to verify. Provider pages and the bulk checker also screen the North Carolina Medicaid list, the New York Medicaid list, the Ohio Medicaid list, the Pennsylvania Medicaid list, the Washington Medicaid list.
