Administration services for these preventive vaccines are reported to Medicare using HCPCS codes as follows: G0008 administration of influenza virus 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.

Use separate administration codes for the seasonal influenza virus (G0008) and pneumococcal (G0009) vaccines. Medicare pays both administration fees if a beneficiary gets both the seasonal influenza virus and the pneumococcal vaccines on the same day.
You would have to use 90471 because G0008 is not a primary code for 90472. Also remember, Medicare doesn't pay for vaccinations outside of the flu, pneomoccocal and HepB. They will pay for tetanus if there is a medical reason for it, but not just a preventative vaccination.
