How we keep it honest
Traceable and conservative by design.
Releases are validated and promoted atomically. Direct identifiers are preferred, exclusion findings require an exact NPI link, and ambiguous name or shared-address matches are never promoted as facts.
Appropriate use
A research aid, not a final determination.
Federal records may be incomplete, delayed, self-reported, or wrong. This is not a consumer report and must not be the sole basis for credentialing, employment, privileging, payment, or exclusion decisions.
Corrections to NPPES records must be made through the official NPPES system. Changes flow into ACOAPI with the next source release.
