NPPES
NPPES — the National Plan and Provider Enumeration System — is the CMS system that assigns and maintains National Provider Identifier (NPI) records.
Updated
The National Plan and Provider Enumeration System (NPPES) is the CMS-administered system that issues and maintains National Provider Identifier (NPI) records. A provider applies for an NPI through NPPES, and the data stored there — name, practice locations, licensure, and provider taxonomy — becomes the reference payers and clearinghouses use to identify and route claims to that provider.
An NPI is a ten-digit, intelligence-free identifier: the digits carry no embedded meaning about the provider. NPPES holds the identifying and practice data associated with that number, and updates to that data (a new practice address, a changed taxonomy) flow through NPPES to the downstream systems that read it.
In practice
Because payers and clearinghouses resolve a provider's enrollment and routing from NPPES data, an out-of-date NPPES record can cause enrollment mismatches and claim rejections even when the practice's own records are correct. Keeping NPPES current is a basic condition of clean claims, and it is separate from (and upstream of) per-payer enrollment.
Commonly confused with
- NPI: The NPI is the identifier; NPPES is the system that assigns and maintains the data behind it.
- PECOS: PECOS is Medicare's provider enrollment system; NPPES assigns the NPI used across all payers. A provider has an NPI through NPPES and, separately, Medicare billing privileges through PECOS.
