The National Provider Identifier (NPI) is a Health Insurance Portability and Accountability Act (HIPAA) Administrative Simplification Standard.  The NPI is a unique identification number for covered health care providers.  Covered health care providers and all health plans and health care clearinghouses will use the NPIs in the administrative and financial transactions adopted under HIPAA.  The NPI is a 10-position, intelligence-free numeric identifier (10-digit number). This means that the numbers do not carry other information about healthcare providers, such as the state in which they live or their medical specialty. Beginning May 23, 2007 (May 23, 2008, for small health plans), the NPI must be used in lieu of legacy provider identifiers in the HIPAA standards transactions.  Covered entities may invoke contingency plans after May 23, 2007, and guidance about contingency plans may be found in the Downloads section below.

If you are a health care provider who bills for services, you probably need an NPI.  If you bill Medicare for services, you definitely need an NPI! Getting an NPI is easy. Getting an NPI is free. The first step is to get your NPI.  If you delay applying for your NPI, you risk your cash flow and that of your health care partners as well.  

As outlined in the Federal Regulation, The Health Insurance Portability and Accountability Act of 1996 (HIPAA), covered providers must also share their NPI with other providers, health plans, clearinghouses, and any entity that may need it for billing purposes. 

More detailed information is available on the pages listed in the left hand column of this page.
