Good Morning - can someone confirm the correct way of billing the following codes for a 78 year old patient? 90732 (Pneumococcal) with G0009 administration code for 90732 and 90715 (Tdap) - do we bill a 90471 or a 90472? I am getting mixed answers. I have been told that G0009 is not considered a "first administration" code so we should bill 90471 for 90715 but when we do G0009 and 90471 bundle.
