What is the NPI compliance date?
A. HIPAA-covered entities, such as providers completing electronic transactions, healthcare clearinghouses, and large health plans, must use only the NPI to identify covered healthcare providers in standard transactions by May 23, 2007 . Small health plans have a one-year extension before complying with the NPI rule so small health plans do not have to comply until May 23, 2008. Small health plans are defined as plans with $4,000,000 or less in revenue.
