I do not know how Medicaid works in your state, but in Florida you have to bill for the vaccine, and 90460 only. If three vaccines were given, you bill for each vaccine seperately and one 90460 code with 3 units. You will receive 0 for each vaccine and $30 for the 90460 (with 3 units). If you are billing for private vaccines you bill for each vaccine seperate(the cost) and 90460(for the first vaccine component) and 90461( one unit for each additional vaccine component).
To determine the vaccine components for private vaccine billing there is coding sheet.
