The Healthcare 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 allows a single provider (individual, group, or institution) to identify their specialty category. Providers may have one or more value associated with them.

Value Set Definition: 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 Type, Classification, and Area of Specialization. The Health Care Provider Taxonomy code set allows a single provider (individual, group, or institution) to identify their specialty category. Providers may have one or more than one value associated to them. When determining what value or values to associate with a provider, the user needs to review the requirements of the trading partner with which the value(s) are being used.
The Dictionary of Occupational Titles (DOT) was created by the Employment and Training Administration, and was last updated in 1991. Therefore, it should no longer be used – it is provided here only for reference purposes. They should never be used in legal proceedings such as workers compensation determinations.
The following notice appears on the US Department of Labor’s Office of Administrative Law Judges website – https://www.oalj.dol.gov/LIBDOT.HTM
The Dictionary of Occupational Titles (DOT) was created by the Employment and Training Administration, and was last updated in 1991. It is included on the Office of Administrative Law Judges (OALJ) web site because it was a standard reference in several types of cases adjudicated by the OALJ, especially in older labor-related immigration cases. The DOT, however, has been replaced by the O*NET (Standard Occupational Classifications - SOC) System).
