Health Care Provider Taxonomy
Choosing a Code
Health Care Provider Taxonomy codes are self-selected by the provider. These codes are for health care providers that are enrolled with payers. Taxonomy codes are not used to define services rendered, but instead are used to define area of specialty. Providers need to determine the most appropriate taxonomy code(s) for them, which is a business decision they need to make based on education and training. Scope of licensure is not within the purview of the taxonomy code set.

The Health Care Provider Taxonomy code set is an external, nonmedical data code set designed for use in an electronic environment, specifically within the ASC X12N Health Care transactions. This includes the transactions mandated under HIPAA.
The Health Care Provider Taxonomy code is a unique alphanumeric code, ten characters in length. The code set is structured into three distinct "Levels" including Provider Grouping, Classification, and Area of Specialization.
The National Uniform Claim Committee (NUCC) is presently maintaining the code set. It is used in transactions specified in HIPAA and the National Provider Identifier (NPI) application for enumeration. Effective 2001, the NUCC took over the administration of the code set. Ongoing duties, including processing taxonomy code requests and maintenance of the code set, fall under the NUCC Code Subcommittee.
