Dental-Provider Specialty Taxonomy Codes
October 6th, 2021 - Christine Woolstenhulme, QCC, QMCS, CPC, CMRS
The National Uniform Billing Guidelines require the use of taxonomy codes for claims submissions on the ADA-Dental claim form and the CMS-1500 Medical Claim form. When reporting the taxonomy code, be sure the provider is contracted with the payer under the taxonomy code being reported. We have listed the general sub-set of taxonomy codes suggested by the ADA, however, the ADA also states, "The general code listed as 'Dentist' may be used instead of any of the other codes."
Dentist: A dentist is a person qualified by a doctorate in dental surgery (D.D.S.) or dental medicine (D.M.D.) licensed by the state to practice dentistry, and practicing within the scope of that license.
