Starting April 1, 2022
You will have new ICD-10-CM Z codes to report if you find the patient you are treating is partially vaccinated or unvaccinated for COVID-19.
The changes include:
- New subcategory Z28.31 (Underimmunization for COVID-19 status), and under it, two new patient status codes:
- Z28.310 (Unvaccinated for COVID-19).
- Z28.311 (Partially vaccinated for COVID-19).
- Z29.39 (Other underimmunization status).
