The National Provider Indetifier (NPI) became the national standard identifier in May 2007.
The Centers for Medicare & Medicaid Services (CMS) has developed the
National Plan and Provider Enumeration System (NPPES)
to assign unique identifiers to health care providers.
The NPPES files contain all of the FOIA-disclosable data
for active and deactivated providers in NPPES.
The source NPPES files have up to 15 provider licenses per NPI.
Jean Roth created the NPI to medicare crosswalk below from the National Plan and Provider Enumeration System (NPPES) downloadable data file for greater ease of use.One limitation of this dataset is that the provider had to include their other provider number on the NPI application in order for the license number to appear here.
Another limitation is that CMS stopped delivering the medicare other provider identifers in January 2018. The files here are based on the December 2017 delivery.
Processed versions of the source NPPES data these files are made from is also available.
CCN's are CMS Certification Numbers.
