Z28.311
ICD-10-CMThis code indicates that a patient has received at least one dose of a COVID-19 vaccine but has not completed the full recommended primary series or booster doses according to current guidelines. It signifies an incomplete vaccination status for SARS-CoV-2.
Apply this code when documenting a patient's COVID-19 vaccination status as partially completed, such as after their first dose of a two-dose series, or if they have not yet received all recommended doses for their age and risk factors. This is relevant for public health reporting, risk assessment, and guiding further vaccination efforts.
