About Z29.8

Z29.8 is the ICD-10-CM diagnosis code for encounter for other specified prophylactic measures. 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 a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within Z29, choose Z29.8 (other specified prophylactic measures) only when documentation doesn't support a more specific option: prophylactic immunotherapy (Z29.1), prophylactic fluoride administration (Z29.3) and prophylactic measures, unspecified (Z29.9).

To report this condition, pick the subcode that matches the documentation: Z29.81 (prophylaxis) and Z29.89 (measures).

It was added in FY2017, effective October 1, 2016, and changed in FY2024.

Before ICD-10, this condition was coded in ICD-9-CM as V07.39 (Need for other prophylactic chemotherapy).
