When will health care providers and health plans begin using NPI?
HIPAA requires that covered entities (i.e., health plans, healthcare clearinghouses, and those healthcare providers who transmit any health information in electronic form in connection with a transaction for which the Secretary of Health and Human Services has adopted a standard) use NPIs in standard transactions by the compliance dates. The compliance date for all covered entities except small health plans was May 23, 2007; the compliance date for small health plans is May 23, 2008. As of the compliance dates, the NPI will be the only health care provider identifier that can be used for identification purposes in standard transactions by covered entities.
