Z29.3Encounter for prophylactic fluoride administration

Z29.3 is the ICD-10-CM diagnosis code for encounter for prophylactic fluoride administration. It belongs to category Z29 (encounter for other prophylactic measures), block Z20-Z29 (persons with potential health hazards related to communicable diseases) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Z29 (encounter for other prophylactic measures), Z29.3 is specifically for encounter for prophylactic fluoride administration. Related codes cover prophylactic immunotherapy (Z29.1), other specified prophylactic measures (Z29.8) and prophylactic measures, unspecified (Z29.9).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It was added in FY2017, effective October 1, 2016.

Before ICD-10, this condition was coded in ICD-9-CM as V07.31 (Need for prophylactic fluoride administration).
