The Health Care 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 is published (released) twice a year on July 1st and January 1st. The July publication is effective for use on October 1st and the January publication is effective for use on April 1st. The time between the publication release and the effective date is considered an implementation period to allow providers, payers, and vendors an opportunity to incorporate any changes into their systems.

Appropriate consideration is given to use of less-invasive and less-harmful interventions, when possible. It also incorporates all appropriate therapeutic approaches, health care modalities, and disciplines to achieve optimal health and healing.
