Important Information: CMS is pleased to announce that
the full replacement monthly NPI File (also referred to as the
NPPES Downloadable File) has now been revised to include
deactivated NPIs and the date of deactivation within the file.
The deactivated NPIs in the file can be displayed by filtering
on the column name "NPI Deactivation Date". In addition, CMS
will also make available a weekly incremental NPI file and a
full replacement monthly NPI deactivation file. Please read the
announcement found on the CMS NPI Data Dissemination page at
regarding these files.
Starting June 18, 2018, the zipped NPPES Downloadable file will also include the following 3 new reference files:
Detailed information about the new files will be included in the Data Dissemination File - Readme file.
- Other Name Reference File - this file contains additional Other Names associated with Type 2 NPIs
- Practice Location Reference File - this file contains all of the non-primary Practice Locations associated with Type 1 and Type 2 NPIs

Beginning with the May 2008 file, the size of the
.csv Header File increased because we added Authorized
Official data elements to it that were inadvertently not
previously included. As a result of the larger size, the
.csv Header File can no longer be opened in Excel. Even so,
the .csv Header File is small enough to be opened by a
simple text editor like Notepad. As always, the .csv data
file must be opened with a text editor capable of opening
large files. Two examples are TextPad and UltraEdit.
The data dissemination file exceeds 4 GB. Older
file compression utilities may not be able to extract this
file properly. Please check your file compression utility
for any known problems and the latest version in order to
avoid any problems extracting this file. Utilities, such as
WinZip and 7-zip, have been successful in extracting the
