What taxonomy code 124Q00000X means

124Q00000X is the National Uniform Claim Committee code for Dental Hygienist, in the grouping Dental Providers. 15,896 NPPES records list it as their primary taxonomy (file of Aug 9, 2026).

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.
