who is required to have a national provider identifier
National Provider Identifier All individual HIPAA covered healthcare providers (physicians, pharmacists, physician assistants, midwives, nurse practitioners, nurse anesthetists, dentists, denturists, chiropractors, clinical social workers, professional counselors, physical therapists, occupational therapists, pharmacy technicians, athletic trainers etc.) or organizations (hospitals, home health care agencies, nursing homes, residential treatment centers, group practices, laboratories, pharmacies, medical equipment companies, etc.) must obtain an NPI for use in all HIPAA standard transactions, even if a billing agency prepares the transaction. Once assigned, a provider's NPI is permanent and remains with the provider regardless of job or location changes.
National identity cards in the European Economic Area Four EEA member states do not issue cards defined by EU as national identity cards to their citizens: Denmark, Iceland, Norway and the United Kingdom (except to residents of Gibraltar); although Norway is expected to start issuing such cards from 1 April 2018.[2] At present, citizens from these four countries can only use a passport as a travel document when travelling between EEA member states, and Switzerland. However, when travelling within the Schengen Area or Common Travel Area, other valid identity documentation (such as a driving licence or EHIC card) is often sufficient.[3] Ireland issues a passport card which is valid as national identity card in other EU countries.[4]
