National Provider Identifier

For Health Care Providers
The Administrative Simplification provisions of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) mandated the adoption of a standard unique identifier for health care providers. The National Plan and Provider Enumeration System (NPPES) collects identifying information on health care providers and assigns each a unique National Provider Identifier (NPI).

Users may experience issues with other browsers and are recommended to use the browsers listed above. It is recommended that browser windows be opened using the icon on the desktop to avoid shared browser sessions. Some browsers share sessions regardless of how the browser is opened. Please check with the browser's vendor about session management. When NPPES detects multiple browsers open within the same session, NPPES will terminate the session to protect the data in NPPES. Data entered will be lost and will need to be re-entered.
