General NPI Information

The NPI is a unique, ten-digit identifier that is issued by the Centers for Medicare and Medicaid Services (CMS) 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.

Claims submitted with invalid NPIs will be rejected

Each claim must pass an NPI check-digit validation to ensure that it has a valid NPI. To date, many claims are not passing this check-digit validation. Claims that fail the check-digit validation will be rejected. The most common reasons why claims are not passing the NPI check-digit validation are:

  • the wrong provider identifier is entered in an NPI field;
  • the NPI is entered incorrectly;
  • the number entered is not a valid NPI.

For more information on how to submit claims, please refer to the Claims submission toolkit for proper electronic and paper claims submissions.

How to obtain an NPI

Providers who have not yet obtained their NPI may apply for it through an easy, Web-based application process that takes approximately 20 minutes to complete online.

You may also call the National Provider Identifier Enumerator call center at 1-800-465-3203 to request a paper application.

Note: The most time-efficient way to obtain an NPI is to complete the Web-based application process.

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