Health Care Provider Taxonomy Codes

Updated: July 2014

The Health Care Provider Taxonomy Code Set is a hierarchical code set that consists of codes, descriptions, and definitions. Healthcare Provider Taxonomy Codes are designed to categorize the type, classification, and/or specialization of health care providers.

The Health Care Provider Taxonomy code set is published (released) twice a year on July 1st and January 1st. The July publication is effective for use on October 1st and the January publication is effective for use on April 1st. The time between the publication release and the effective date is considered an implementation period to allow providers, payers, and vendors an opportunity to incorporate any changes into their systems.

The Health Care Provider Taxonomy code is a unique alphanumeric, 10-digit code. The code is structured into 3 distinct Levels, including provider type, classification and area of specilization. While existing Level I and Level II codes have been defined, Level III specialization codes have not. Select the Level II area of specialization on the left to view the description and details along with any related Level III taxonomy codes.

Effective 2001, the National Uniform Claim Committee (NUCC) is maintaining and administering the code set. It is used in transactions specified in HIPAA and the NPI application for enumeration.
