What is my taxonomy number?

Physicians may report primary and secondary taxonomy codes in the NPI application. For instance, a family medicine physician specializing in adolescent medicine might report a primary code for family medicine, 207Q00000X, and a secondary code for adolescent medicine, 207QA0000X.

For family nurse practitioners, the taxonomy code is 363LF0000X. For family medicine clinical nurse specialist, the taxonomy code is 364SF0001X. Physician Assistants in the medical practice are assigned taxonomy code 363AM0700X. For students, taxonomy code 390200000X is assigned. Interns should report the general practice taxonomy code, 208D00000X. Residents should report the taxonomy code for the specialty of the residency program.

If applying for an NPI for an organization, a group taxonomy code may be required. For taxonomy codes, a group practice is defined as a business entity under which one or more individuals practice. A group does not require multiple professional providers. A single provider group is a valid group and would be identified by the business entity name, for instance - John Doe, PC. For single specialty groups, the taxonomy code is 193400000X. For multispecialty groups, the taxonomy code is 193200000X.
