Who must obtain an NPI?

Individuals identified in any covered electronic healthcare transaction must obtain an NPI that remains associated with the individual for life. All healthcare providers, defined under the regulation as providers who access claims information or benefits via the Internet are also covered entities.

The broad definition of healthcare "provider" provided in the regulation encompasses all who provide healthcare services: individuals (including physicians and all other practitioners) as well as organizations (such as hospitals, pharmacies, clinics and medical supply companies).

Legal entities must obtain at least one NPI. The organization may obtain additional NPI’s through enumeration of subparts.
