HealthCare Provider Taxonomy Codes Lookup

Updated on July 01, 2023. Version 23.1

Healthcare Taxonomy Codes are used for a variety of reasons which include specialization of health care providers, classification, and type. The Healthcare Taxonomy Set is designed in a hierarchical order that consists of definitions, descriptions, and codes.

The taxonomy code set is updated and published semi annually in January and July of each year. The January publication is available to be used in April and the July release is available to be used in October of that year. The implementation period is the elapsed time between the release date and the effective date. This time allows for vendors, payers, and providers the chance to incorporate all changes into their platforms and systems.
