The code for getting the flu vaccination is Z23, which is the same for any immunization. In October 2017, an ICD-10-PCS code (3E01340) was added to capture the administration of the influenza vaccine.
For vaccines given the same day as a G-Code vaccine, use 90471. For example, if a patient receives a flu shot and tetanus shot, you would bill G0008 for the flu vaccine and 90471 for the tetanus vaccine; also add modifier 59 (distinct procedural service) to the G code.

The procedure codes are used to identify the type of the immunization given and how it was administered. All Z codes must be accompanied by a corresponding procedure code.
