Electronic File Interchange (EFI) Information
The National Council for Prescription Drug Programs (NCPDP) intends to become a CMS certified Electronic File Interchange
(EFI) Submitter for obtaining and maintaining National Provider Identifiers (NPIs) on behalf of pharmacies. The
requirements for EFI Submitters are currently in development by the Centers for Medicare and Medicaid Services (CMS). CMS
could publish these requirements approximately summer 2005. As a result, NCPDP is urging pharmacy owners to delay applying
for their pharmacy's NPI so NCPDP can submit applications in bulk as an administrative service for the pharmacy segment of
healthcare.
