The NPI Number is a unique 10-digit number issued by the CMS (Centers for Medicare & Medicaid Services) to health care providers in the United States.
Since 1996, HIPAA requires the adoption of a standard unique number for health care providers. The NPI Final Rule, issued in Jan 2004, has adopted the NPI number as that standard for health care provider identification. The NPI has replaced the UPIN (Unique Provider Identification Number) as the required identifier for all Medicare services, including health insurance claims.
