NPI Lens

Bulk NPI verification

Paste a list or upload a CSV. For every row you get NPI status (active, deactivated, invalid), a name check, the primary specialty, an OIG exclusion list result and Medicare enrollment / opt-out status. Free for up to 100 rows per run.

Your list

One NPI per line works. With a header row, columns named npi, first_name,last_name and organization turn on the name check.

Your list is checked in memory and not stored. Data: NPPES Nov 2, 2026, OIG list Oct 9, 2026.
