If you already have your national provider identifier (NPI), but have recently changed your office contact numbers, address or contact person, you will need to update your NPI as soon as possible. Depending on whether you qualify as an individual or small group practice, or are considered a large organization, your qualification will determine how you can update your NPI of record.

Things You Will Need
  • Application form CMS 10114

  • Legacy provider number

  • UPIN number

  • Taxonomy code

  • License numbers of practitioners

  • Mailing address

  • Practice address

  • Contact person information

Step 1.

Determine if you will be considered a large organization by NPI Enumerator, Inc. If your practice (solo or group) is joined together with other groups for the purpose of gaining batch NPIs, then you are a large organization and eligible to use the electronic file interface (EFI) to update the numbers assigned to your organization. An example of a large organization would be several individual practices that come together to provide services for the Department of Health and Human Services, such a group would be issues NPIs under a single organization rather than individually to assist the tracking and processing of claims by Health and Human Services. If you qualify, use the "Electronic File Interchange Summary" link at the bottom of this article to find out more information about registering to use the EFI service. If you do not qualify as a large organization, continue reading.

Step 2.

Choose whether to file the application to update your NPI online or by mailing in a paper application. Filing an application online tends to be faster. If you want to submit a paper application, go to the main NPI site to download and print form CMS 10114. If you wish to file the paperwork online, go to the NPI site using the link at the bottom of this article. Either way, the information required to fill out the forms will be the same.

Step 3.

Fill out the form with the following information: legacy provider number (this is your original NPI number), UPIN number (this is your assigned PIN access number for the NPI administrative network), taxonomy code (these are your health care specialty codes), the license numbers of all practitioners involved with your group, the group's mailing address, the physical address of the practice, and the contact person's name and phone number.

Step 4.

You will also be asked to provide your name, social security number, birth date and license number (of any) in the section detailing who filed the application.


Even if you choose to file your application online, gather together all the required information and have it written on one piece of paper to speed the process of filling out the form.


Federal Regulations require you to update your NPI in the event of any change that occurs within your practice in regards to location, specialty codes and licensed practitioners associated with your practice.
