National Provider Identifier (NPI)

What is the NPI?

The NPI is a unique, ten-digit identifier that the Centers for Medicare & Medicaid Services (CMS) issue to all health care providers as mandated by the federal government via the Health Insurance Portability and Accountability Act of 1996 (HIPAA). The NPI eliminates the need for multiple identifiers from different health plans. All covered entities under HIPAA must obtain an NPI.

How to Get an NPI

Providers who need an NPI may apply for it in one of two ways:

  • Online. This is the quickest and easiest way to obtain an NPI. The online application takes approximately 20 minutes to complete.
  • By mail. Request a paper application by calling the National Provider Identifier Enumerator call center at 1-800-465-3203.

Once an NPI application has been successfully processed, the applicant will receive an NPI confirmation notice, including an automatically issued ten-digit NPI. Web applicants will receive confirmation by email; paper applicants will receive confirmation by standard mail.

Help avoid rejected claims: use a registered, valid NPI.

Use a Valid NPI For All Claims

Our system reviews each claim to ensure it contains a valid NPI. To date, many claims are not passing this validation stage. Claims that fail the validation stage are automatically rejected.

Most common reasons why claims are not passing the validation stage:

  • the wrong provider identifier is entered in an NPI field;
  • the NPI is entered incorrectly;
  • the number entered is an invalid NPI.
