Whether you're a resident, medical student, or are starting your career as a physician, you'll need to have a National Provide Identifier number. This number will be used any time you transmit certain pieces of information required by HIPAA regulations. Here's what you need to know about NPIs, what they're used for, and how to get one.
Whether you plan to work in a private practice, in a hospital, or as a locum tenens physician, all healthcare providers who are HIPAA-covered entities — and those who bill Medicare for their services — must have a National Provider Identifier (NPI).
This 10-digit number is a unique, government-issued, standard identification number for individual healthcare providers that does not expire or change. Provider organizations like clinics, hospitals, pharmacies, schools, and group practices can also have NPI numbers.
You will need an NPI number prior to submitting claims or conducting other transactions as specified by HIPAA, including the situations listed below:
For more information, refer to the Transactions Overview page.
As healthcare providers, residents, interns, and medical students, you are all eligible to apply for an NPI. If you transmit any kind of health data for a HIPAA-standard transaction, you are required to have one. For example, if you are prescribing medications for patients that are filled by pharmacies, ordering tests for patients for other healthcare providers, or referring patients to other providers, you need to have an NPI number.
Before you submit your application, ensure you have the following pieces of information:
Applying for your NPI number is free. You can apply online, by mail, or through a designated CMS contractor. The online application is recommended because it is generally quicker and easier to track the status.
2. By Mail: Complete, sign, and mail a paper NPI Application/Update Form to
7125 Ambassador Road Ste 100
3. Designated CMS contractor: Give permission to an Electronic File Interchange Organization (EFIO) to send application data through bulk enumeration process.
The NPPES website also contains frequently asked questions and other helpful information.
After your application has been accepted, you will receive your NPI via email from Customerservice@NPIEnumerator.com. Be sure to check your spam folder regularly — or add this email address to your trusted sender list — so you don’t miss it.
The amount of time it takes to obtain an NPI is dependent upon the volume of applications being processed at a given time, whether the application was submitted electronically or on paper, and whether the application was complete. A provider who submits a properly completed electronic application could have an NPI in 10 days. The paper application process takes approximately 20 business days.
To obtain your National Provider Identifier, go to https://nppes.cms.hhs.gov/ or call customer service at 800.465.3203. Questions about the status of an NPI application may be emailed to customerservice@NPIEnumerator.com.
