Health Care Provider Taxonomy Codes

Last updated July 01, 2019 with Version 19.1

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.


Dental Hygienist - 124Q00000X

An individual who has completed an accredited dental hygiene education program, and an individual who has been licensed by a state board of dental examiners to provide preventive care services under the supervision of a dentist. Functions that may be legally delegated to the dental hygienist vary based on the needs of the dentist, the educational preparation of the dental hygienist and state dental practice acts and regulations, but always include, at a minimum, scaling and polishing the teeth. To avoid misleading the public, no occupational title other than dental hygienist should be used to describe this dental auxiliary.
