1. You must select a taxonomy by using the Add Taxonomy button
to navigate to Select Taxonomy Page.

3. To remove a previously selected taxonomy, click the delete button
for that taxonomy to remove it from your application.
4. Some organization providers may decide to obtain a single NPI,
and not obtain NPIs for their subparts. If an organization provider
takes this approach, that provider might want to furnish taxonomy codes
that represent not only itself, but also its subparts if their
taxonomies are different from that of the organization. Later on,
if the organization provider determines that its subparts should
have their own NPIs and the subparts obtain them, the organization provider
should go into NPPES and update its record by deleting the taxonomies
that describe its subparts.
5. Individuals who are sole proprietors may select taxonomies from
either the Individual or the Non-Individual sections of the taxonomy
code set. In the event that the answer to the sole proprietor question
is changed from “Yes” to “No,” and the provider had selected a taxonomy
code from both sections of the taxonomy code set, NPPES will display
error messages under each of the applicable taxonomies so that the
provider will know which one(s) to delete to keep the NPPES record accurate.
6. If you select Multi-Specialty Group (193200000X) or Single-Specialty
Group (193400000X) be aware that NPPES will require you to select the area
of specialization (e.g. Internal Medicine, Family Practice) of the
members of the group.
7. One of the taxonomies listed on this page must be selected
as the Primary Taxonomy before continuing the application process.
8. If SSN or ITIN was reported as an Individual’s License Number for a
Taxonomy that requires the reporting of a License Number, CMS has removed
the License Number and has replaced it with the following text: "SSN/ITIN deleted"
followed by a series of unique numbers.
9.If you enter an SSN/ITIN/EIN in the License Number field you will be shown
a warning message that an invalid entry has been made and to update this field.
If you choose to Save the invalid entry NPPES will convert it into a character
string to protect the SSN/ITIN/EIN from being disseminated to downstream systems
in clear text. If you entered an SSN it will be converted into 9 dollar signs ($),
an EIN will be converted into 9 equal signs (=) and an ITIN will be converted
into 9 asterisks (*). Only numbers that exactly match the SSN/ITIN/EIN entered
on your record will be converted, if your SSN/ITIN/EIN report in NPPES changes
the previously converted numbers will now display.
