NPI: Taxonomy Help

The Health Care Provider Taxonomy Code (HCPTC) set is an external non-medical data code set designed for use in classifying health care providers according to provider type or practitioner specialty in an electronic environment, specifically within the American National Standards Institute (ANSI) Accredited Standards Committee (ASC) health care claim transaction. The HCPTC list is a collection of unique alphanumeric codes, 10 characters in length, called taxonomy codes. The code set is structured into three distinct "levels," including provider type, classification and area of specialization.

The taxonomy codes allow a single provider (individual, group or institution) to identify their areas of specialization. Providers may have one or more areas of specialization. When determining what value or values to associate with a provider, the user needs to review the requirements of the trading partner with which value(s) are being used.

Below is additional information about provider taxonomy codes and descriptions:
