A Guide to NPIs

A National Provider Identifier (NPI) number is a unique 10-digit id assigned to healthcare providers. NPI numbers allow insurance companies to do their job efficiently. NPI numbers are free, easy to obtain, and make it much simpler for providers to help their out-of-network patients get reimbursed for medical bills.

National Provider Identifier (NPI) numbers, a guide:

What is a NPI?

A NPI is a unique 10-digit identification number – representing a distinct health care provider – for individuals and organizations alike. Having a NPI simplifies the exchange of healthcare information. A provider’s NPI is associated with information that health insurance companies use to identify and categorize the types of services they provide. This information helps insurance companies verify the provider’s information and identify their patients’ claims. It helps patients get reimbursed more quickly while reducing the likelihood of errors.

The NPI system was created to allow the full range of providers, from sole providers to hospital/medical groups, to transmit and exchange patient health information. NPI numbers are universally used by health plans in correspondence with providers, in both EHR and medical billing systems, and for claims, prescriptions, and more.

There are benefits for every provider getting a NPI number, and they’re free.

How does a NPI simplify billing?

A patient who wants to get reimbursed must file a claim and submit a coded receipt or “superbill” — from their provider — to their health insurance. If that superbill includes the provider’s NPI number, it makes it faster and easier for the patient to get paid back.

You can find more information about superbills in our guide.
