Question 1

How to use the taxonomy code lookup?

Accepted Answer

Type a NUCC taxonomy code (207Q00000X) or a specialty name (“family medicine,” “psychiatry”) into the search bar. Filter by grouping or classification to narrow results. Open any result for the full definition, NPI counts, related codes, and linked billing and policy context.

Question 2

What is a provider taxonomy code?

Accepted Answer

A provider taxonomy code is a 10-character NUCC code that classifies healthcare providers by type, classification, and specialization. For example, 207Q00000X for Family Medicine. Payers and CMS use these codes for credentialing, directory listings, and claims routing.

Question 3

What are grouping and classification?

Accepted Answer

Grouping is the top NUCC level (for example, Allopathic & Osteopathic Physicians or Hospitals). Classification narrows that to a specialty or facility type (Family Medicine, General Acute Care Hospital). Specialization, when present, adds a further focus within the classification.

Question 4

How do I find the taxonomy code for a specialty?

Accepted Answer

Type the specialty or facility type in the search bar. For example, “psychiatry” or “acute care hospital”. Open the best match to confirm the full NUCC definition before using the code on a claim or credentialing form.
