NPI (National Provider Identifier)

What is NPI?
NPI is the National Provider Identifier that has been established to standardize the identification number for health care providers. The NPI replaces many proprietary provider identifiers. The NPI is a 10 digit number that will be assigned by a CMS funded enumerator through NPPES (National Provider and Plan Enumeration System).

Please be aware that Wisconsin Physicians Service Insurance Corporation (WPS) began accepting 837 Electronic Data Interchange (EDI) transactions with NPIs as of January 1, 2006. Until further notice, you must also provide the legacy provider number to us when reporting the NPI. We have been informing providers to contact their vendor/clearinghouse to ensure they have appropriate programming in place to allow them to submit their electronic files, complete with the NPI. WPS will be sending you additional correspondence in the future related to NPI and your EDI transactions, along with any other related educational information.

Please contact us at (800) 782-2680 Option #2 if you require additional information.
