Inoculations and vaccinations (Z23)
Official text from the FY2027 ICD-10-CM Official Guidelines for Coding and Reporting. The wording is quoted exactly.
Guidelines I.C.21.c.2
“Procedure codes are required to identify the actual administration of the injection and the type(s) of immunizations given.”
“Code Z23 may be used as a secondary code if the inoculation is given as a routine part of preventive health care, such as a well-baby visit.”
