Z29.3

Encounter for prophylactic fluoride administration

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/12/2025

Code Description

ICD-10 Z29.3 is a billable code used to indicate a diagnosis of encounter for prophylactic fluoride administration.

Key Diagnostic Point:

Z29.3 is used to indicate an encounter specifically for the administration of prophylactic fluoride, a preventive measure aimed at reducing the risk of dental caries (cavities) in patients, particularly children. Fluoride treatments can be administered in various healthcare settings, including dental offices, primary care clinics, and public health facilities. The decision to provide fluoride treatment may be influenced by social determinants of health such as socioeconomic status, access to dental care, and community health initiatives. Preventive care, including fluoride administration, is essential in promoting oral health and preventing dental diseases, which can have broader implications for overall health and well-being. Documentation should reflect the patient's risk factors for dental caries, the rationale for fluoride treatment, and any relevant social factors that may impact oral health.
