NPI number: what is it?

Blog

The NPI, or National Provider Identifier, is a non-repeatable number for health care providers. The NPI always consists of 10 digits and is used for administrative and financial procedures. The NPI was introduced in 1996 to make electronic health records more efficient. The fact is that the most common error in billing for medical care in an area is to have the wrong NPI number or no NPI number at all. Thus, it is simply not possible to pay for the service.

Who might need an NPI number?

An NPI number must be obtained:

  • Anyone who provides medical services;
  • Medical organizations.

Once a professional or company is assigned an NPI number, it cannot be changed, even if the provider moves, changes positions, or moves to another job.

What two types of NPIs exist?

Type 1:  NPI individual.

This type includes sole proprietors who work in a particular area of medicine. This could be dentistry, dermatology, surgery, gynecology, etc.

Type 2: organizations.

This includes companies and institutions. For example, a hospital, nursing home, urgent care facility, physician commonwealths, etc., as well as those already registered as providers.

How did NPI numbers come about?

The history of NPI begins in 1993, when the Centers for Medicare and Medicaid Services developed a project to create an identification system for each health care provider. As a result of all the changes, NPIs were introduced to replace the unique physician identification number. And UPINs ceased to exist in 2007.

What is the fastest way to get an NPI?

To get an NPI number quickly, you need to fill out and submit an application to NPPES. It takes about 20 minutes to fill out such an application. The fastest way for providers and organizations to get an NPI number is to apply through the National Plan and Provider Enrollment System (NPPES). It takes about 20 minutes to complete the application, and an NPI number can be obtained in as little as 10 days. Individual providers must first create a username and password through the Identity and Access Management System and log into NPPES using those credentials.

Providers can also apply for an NPI number through a paper form or through an organization on their own behalf. Complete instructions can be found on the CMS website.

Because the NPI is required by HIPAA regulations to track health care services and reimbursements, health plans will deny any application submitted without a valid, registered NPI.

Does the provider's NPI change?

Once a provider's NPI is assigned, the provider's NPI does not change. The NPI remains with the provider regardless of a change of employment or location.
Does the NPI replace the taxpayer identification number (TIN) or other identification numbers?

The NPI does not replace numbers used for other identification purposes, including the provider's taxpayer identification number (TIN), Drug Enforcement Administration registration number, license number, or Social Security number. However, it replaces any previous identification numbers that providers used for medical information transactions, claims and billing. Health insurers may continue to use provider identification numbers other than NPI, but NPI must be used for HIPAA transactions.

Look up NPI number

There are many ways to search for NPI for a provider or organization. The official NPI search site is the NPI NPPES registry. It is a free service that is open to everyone. You can start your search with the NPI number or with the name. Search results include the NPI number, provider name, type of NPI labeled with icons, primary practice address, phone number, and primary taxonomy. The results are displayed in the search results window and can be downloaded or, alternatively, retrieved through the application programming interface.
