National Provider Identifier

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 must 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. 
  • The provider’s NPI will not change and will remain with the provider regardless of job or location changes.
  • The NPI must be used in lieu of Medicaid legacy IDs (UPIN, OSCAR, PIN, and National Supplier Clearinghouse or NSC). In North Carolina, the NPI replaces the Medicaid Provider Number (MPN).

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.
