ICD-10 requires only one code (Z23) per vaccination, regardless if single or combination. Report Z23 for all vaccination diagnoses.
According to ICD-10-CM guidelines, clinicians may assign code Z28. 310, “Unvaccinated for COVID-19,” when the patient has not received a dose of any COVID-19 vaccine. Clinicians may assign code Z28.
Code Z23 is used to indicate any encounter for a vaccination. The procedure codes are used to identify the type of the immunization given and how it was administered.
Z23 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM Z23 became effective on October 1, 2021.
The Z23 code includes the following note: “Code first any routine childhood examination.” Therefore, when you provide immunizations in conjunction with a well-child visit, a code for routine child health examination should be reported first, followed by Z23 for any immunizations. This is similar to ICD-9 rules.
Z23 may be used as a primary diagnosis for immunizations in the OP and physician setting.
Code Z23, which is used to identify encounters for inoculations and vaccinations, indicates that a patient is being seen to receive a prophylactic inoculation against a disease. If the immunization is given during a routine preventive health care examination, Code Z23 would be a secondary code.
