National Provider Identifier

What is an NPI?

The federal Health Insurance Portability and Accountability Act (HIPAA) requires you to obtain an NPI if you submit claims electronically or if you check claims status or access patient eligibility and benefits information online. All individual health care providers (including dentists) and organizations such as clinics and group practices are eligible to obtain an NPI.

Answering "yes" to any one of the following questions requires you to obtain and use an NPI per federal law:

  • Do you submit claims electronically?
  • Do you use a clearinghouse?
  • Do you submit claims attachments electronically?
  • Do you use the Internet to obtain eligibility, benefits information or check claims status?

What is an NPI?

  • A 10-digit random number unique to each health care provider or organization
  • An NPI contains no coded information about the provider or organization
  • A permanent identifier that does not change over time or expire
  • A replacement for other identifying numbers currently used in electronic transactions, such as the Medicaid, Blue Cross and Blue Shield, UPIN, CHAMPUS and certain other "legacy" numbers
  • Not a replacement for social security numbers, DEA numbers, taxpayer ID numbers (TIN or EIN), specialty identifiers (taxonomy) or state license numbers
  • Issued by the government through a third-party group, the National Plan & Provider Enumeration System (NPPES), which is responsible for processing applications and assigning numbers

Which NPI is Right for You – Type 1 or Type 2?

There are two types of NPIs: Type 1, for individual health care providers, such as dentists and hygienists, and Type 2 for incorporated businesses, such as group practices and clinics. When submitting claims, the NPI-1 will always be required for the rendering/treating dentist.

  • Type 1 is for the individual provider. This is the only type of NPI you will need if you receive payments in your name as a solo practitioner. For practices with multiple dentists, obtain a Type 1 NPI for each dentist.
  • Type 2 is for group practices, incorporated dental practices or other business entities paid under their business or corporate name.
