HIPAA provisions require all healthcare providers to have a National Provider Identifier (NPI). This number is a unique, government-issued, standard identification number for individual healthcare providers as well as provider organizations like clinics, hospitals, schools, and group practices. You will need one prior to submitting claims or conducting other transactions as specified by HIPAA. The 10-digit number is used by all health plans and does not expire or change.

Applying for an identifier is a free, simple, 20- to 30-minute procedure that will save healthcare providers time and headaches in the future.

To apply online, visit the National Plan and Provider Enumeration System (NPPES) website, read the instructions carefully, complete the questionnaire, and submit your application. The website contains frequently asked questions and other helpful information.

A provider who submits a properly completed electronic application could have an NPI in 10 days. The paper application process takes approximately 20 business days.
