NIP stands or national provider identifier. It is the only healthcare provider identifier that can be used for identification purposes in standard transactions by covered entities. According to HIPAA act (Health Insurance Portability and Accountability Act) , covered entities should use or national provider identifier in standard transactions. Instead of legacy provider identifiers, such as UPIN in HIPAA standard transactions, the NPI number lookups must be used to process all medical claims.
All individual HIPAA covered healthcare providers, including physicians, physician assistants, chiropractors, professional counselors, physical therapists, occupational therapists, pharmacy technicians and more, or organizations including hospitals, home health care agencies, nursing homes, residential treatment centers, group practices, laboratories, pharmacies, medical equipment companies and more must obtain an national provider identifier for use in all HIPAA standard transactions. When the NPI is assigned to someone, it remains permanents with that individual or health worker and it won’t change even if that person changes his/her job or location.

Check for every healthcare provider in the NPI Registry. You can check by individual name search or NPI number search. The NPPES was established by the Centers for Medicare & Medicaid Services (CMS) to grant all health care providers a specific 10-digit NPI number in compliance with the 1996 Health Insurance Portability and Accountability Act (HIPAA).

Although the NPI registry is regularly updated but to show the updates it takes some time. You should also know that names are spelled with different variations such as “Flower” vs “flour” and “chilly” vs “chili”. So if you try to find someone with a name then we recommend you to change the spellings too. Additionally, some providers in the database do not keep their information up-to-date when their practice changes or moves.
