Provider screening signals
NPI-keyed source families read directly for 1649263468: federal and state integrity lists, CMS Open Payments, Order and Referring eligibility, Medicare opt-out, and enrollment revalidation. Cells expose the source and provenance fields supplied by the selected record. A screening aid — re-confirm any match against the primary source before acting; absence means nothing on file in the data Fonteum currently holds, never a guarantee none exists.
