How to Change the Address of Your Data Recording NPI

by Lisa Baker

The National Provider Identifier (NPI) number is assigned to all health care providers by the National Plan and Provider Enumeration System (NPPES). Since May 23, 2007, this unique number has been required of all health care providers as part of the Health Insurance Portability and Accountability Act of 1996 (HIPAA). Because this number is used to identify health care providers in standard transactions, such as health care claims, it is important to keep all information with NPPES current. You must update your information NPI within 30 days of the effective change, and you can do so online or by mail.
