National Provider Identifier

National Provider Identifier header

E-claims must include the dentist's Type 1 NPI

Federal law (HIPAA) requires all health care providers and organizations to use a standard identifier on all electronic transmissions that include patients' health information, such as electronically submitted claims. This standard identifier is the National Provider Identifier (NPI), and it is assigned by a federal government agency.

Any dentist can get an NPI and use it on both electronic and paper claims; however, as of May 23, 2008, all heath care providers and organizations that meet the HIPAA definition of a covered entity are required to use an NPI to identify themselves in HIPAA standard transactions.

Read more information about HIPAA and the NPI.

Using the NPI

All e-claims sent to Delta Dental must include:

  • The treating dentist's Type 1 identifier.
  • The treating dentist's state license number.
  • The tax identification number (TIN) of the billing dentist or practice.

Note: The Type 2 NPI may be entered in addition to the Type 1 NPI to identify the billing provider (such as a group practice).
