When billing VFC what your allowed to bill per shot is the admin fee since you dont bill for the vaccine. So for you to get anything else you will have to bill for an office visit 99211 you must do ht and wt. 90471 is what we use to bill commercial insurance per component for admin fee. So for VFC you cannot bill anything else but the admin per shot and an office visit 99211, from what I know. Hope that makes sense.
