What is a Health Care Provider Taxonomy Code Set

The Health Care Provider Taxonomy code set is a collection of unique alphanumeric codes, ten characters in length. The code set is structured into three distinct “Levels” including Provider Grouping, Classification, and Area of Specialization. – source: nucc.org

The below example shows these “Levels” for Family Practice Physicians. All doctors are placed under a grouping of services called Allopathic & Osteopathic Physicians. Next, Family Medicine is listed as a more specific service or occupation related to that provider grouping (under Classification). Finally, a list of more specialized areas is displayed on the last level called Specialization. It shows the areas in which a provider chooses to practice or make services available.
