National Provider Identifier (NPI)

The National Provider Identifier (NPI) is a requirement of the Health Insurance Portability and Accountability Act (HIPAA). NPI's will recognize providers and eliminate the need for multiple identifiers when conducting electronic transactions.

Recently we learned that several providers still do not have their NPI on file with MHN. As a reminder, beginning May 23, 2008, providers are required to submit an NPI number with all electronic transactions. Even if you are not submitting electronic claims, having your NPI on file will help us to expedite processing claims. If you are submitting electronic claims and do not provide a valid NPI on the submission, your claims will be returned to provide the required information.
