Yes we are billing the admn fee for VFC vaccine for children 18 and under. We cannot bill 99211 for immunization admn fee due to the fact that we do not do height & weight on the patients. We use modifier SL with each vaccine code. Has anyone billed for the admn fee for immunizations using the cpt code 90471? Is anyone familiar with modifier 59? Thanks for the all the feedback. It is really helpful!
