How coders use this code
ICD-10-CM Z28.1 is a billable, fully specified code, so it can be reported directly on a claim to document a diagnosis of immunization not carried out because of patient decision for reasons of belief or group pressure. Coders assign it when the chart documentation supports this level of detail, always matching to the most specific code available and verifying against the chapter-specific guidelines published annually by NCHS/CMS.
