National Provider Identifier (NPI)

Anyone who uses standard electronic transactions, like electronic claims, eligibility verifications, claims status inquiries and claim attachments, is required by federal law to use NPIs on all electronic transactions. In addition, those dentists who use only paper, voice and fax to transmit these communications may find NPIs useful or necessary for other reasons. The ADA encourages all dentists to obtain and use a NPI, particularly those using (or planning to use) electronic transactions. The NPI will replace other identification numbers issued by health plans and will be required for electronic transactions and, at insurers' discretion, for paper transactions.
Dentists can apply online at the NPPES NPI Registry .
