How will a provider be issued a NPI?
Providers are able to apply to CMS for a NPI starting May 23, 2005 and must have a NPI by May 23, 2007, when exchanging electronic transactions (small health plans have until May 23, 2008). Applications are available on the CMS web site at http://www.cms.hhs.gov/NationalProvIdentStand/03_apply.asp. Providers will need to supply adequate information to ensure that they can be identified uniquely by the National Plan and Provider Enumeration System (NPPES). Should any of that information change in the future, CMS must be notified within 30 days.
