Update Practice Information

check mark iconDelta Dental processes claims, mails checks and sends information to you by using the dental information maintained in our records. This is also the information that appears in our print and online directories that our members use to find dental offices near their home or place of business.

Please let us know immediately of any changes to the following information:

Should you use a Tax Identification Number or Social Security number?

Delta Dental requires the dentist’s state license number and Tax Identification Number (TIN) on all claim forms. The numbers on the claims must match the information in our records or the claims will be rejected. Accuracy is necessary, because those numbers are used to report annual payment amounts to federal, state and local tax agencies.

A dental practice has two options for their business TIN: the dentist’s Social Security number (SSN) or an Employer Identification Number (EIN). An EIN is a nine-digit number assigned by the Internal Revenue Service to identify the tax accounts of a business. The EIN identifies only the business, even if the dentist uses his or her name as the business name.

A business TIN is not legally protected information; any business information that is not protected by law can be available for public access. Business TINs can be published in business documents, posted online or be available through government records because they are not legally designated as proprietary information. Due to the public availability of this information, dentists who use a personal SSN as a business TIN may be putting themselves at risk for invasion of private information and identity theft.

For more information or to apply for an EIN, go to www.irs.gov/businesses/index.html.

REMINDER: Federal law (HIPAA) requires all health care providers to use their National Provider Identifier (NPI) for electronic transactions as of May 23, 2008. For information on obtaining your NPI, visit: https://nppes.cms.hhs.gov.
