What is an NPI Number?
The National Provider Identifier (NPI) is a Health Insurance Portability and Accountability Act (HIPAA) Administrative Simplification Standard. The NPI is a unique identification number for covered health care providers. It is a 10-digit numerical identifier used to identify an individual provider or a health care entity. Covered health care providers, all health plans, and health care clearinghouses must use NPI numbers in the administrative and financial transactions adopted under HIPAA.

Do nurses have an NPI number?
Yes. Nurse practitioners and physicians assistants need to have one as well as midwives. HIPAA says that all health providers must have an NPI. When it says health care providers then it means a provider of services (as defined in section 1861(u) of the Act, 42 U.S.C. 1395x (u)), a provider of medical or health services (as defined in section 1861(s) of the Act, 42 U.S.C. 1395x(s)), and any other person or organization who furnishes, bills, or is paid for health care in the normal course of business.
Type of NPI required by the Nurse practitioner
Generally, there are two types of NPI and these are as follow:-
Type 1:- It is required by individuals or sole practitioners such as doctors, nurses, etc.
Type 2:- It is required by organizations such as hospitals, nursing homes, etc.
Here we can say that nurses can apply for Type 1 NPI.
