The Health Care Providers Taxonomy Code dataset is © Copyright 2022 of the American Medical Association. The code set is designed for use in electronic health care transactions mandated under HIPAA.

The 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 National Uniform Claim Committee (NUCC) maintains the taxonomy code set. For additional information visit
