Health Care Provider Taxonomy Codes

The health care providers taxonomy codes are unique alphanumeric codes, ten characters in length. The codes are divided into three distinct "levels": Provider Grouping, Classification, and Area of Specialization. The code set levels are organized to allow navigating down from generic classification to a provider's most specific level of specialization. The code set is designed for use in electronic health care transactions mandated under HIPAA.

Taxonomy codes are self-selected by the health care providers. Their specialty is defined based on their education level and training. Taxonomy codes do not specify the actual services rendered by the health care provider.

The National Uniform Claim Committee (NUCC) maintains the taxonomy code set. The taxonomy code set is updated twice a year on January 1st and July 1st. The January update is effective on the next April 1st of that year while the July update is effective on October 1st of the same year. The current taxonomy code version is NCCU Provider Taxonomy Version 20.1 and was last updated on July 1st, 2020. For additional information visit
