What it is
A standard-dose flu shot protects against the influenza strains expected in the coming season, and the formula changes every year. This code is the preservative-free version given to most people.
What the price covers
The price is for the vaccine dose. Giving the shot is usually a separate line (code 90471 for the first vaccine of the visit); Medicare bills use G0008 instead.
