Questions

Is 363L00000X the right taxonomy code for a nurse practitioner?
Yes. 363L00000X, Nurse Practitioner, is the code SimpleNPI files for nurse practitioners. Related codes some choose instead: 363LF0000X (Family Nurse Practitioner), 363LP0808X (Psychiatric/Mental Health Nurse Practitioner), 363LA2200X (Adult Health Nurse Practitioner), 363LG0600X (Gerontology Nurse Practitioner), 363LP0200X (Pediatric Nurse Practitioner), 363LW0102X (Women's Health Nurse Practitioner), 363LA2100X (Acute Care Nurse Practitioner).
Can I change my taxonomy code later?
Yes, for free, in your NPPES account. Add the new code with its license, make it primary, and remove the old one if it no longer applies. The NPI itself never changes.
Does 363L00000X have to match my license?
It should describe the profession your license covers. Payers compare the taxonomy with the license during credentialing, and a mismatch slows that down.
