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

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
