CPT code 90471: Immunization administration

CPT code 90471 is used to report a single vaccine's administration via intramuscular, subcutaneous, oral, or intranasal routes during an immunization visit. It is used when only one code is needed to capture the first vaccine given, without any evaluation and management service reported on the same day.

You can bill CPT 90471 once per visit, as it covers the initial vaccine administration. If additional vaccines are administered during the same encounter, use CPT 90472 as a secondary code for each additional injection or dose.

For vaccine-related injections, CPT code 90471 is the primary code for reporting the first immunization's administration. Different codes apply to therapeutic or diagnostic non-vaccine injections, such as 96372, for a therapeutic injection given intramuscularly or subcutaneously.
