A patient was seen for their newborn WCC. Upon obtaining the Hx, it was found that the mother did not have adequate prenatal care and the child was born at home with no antenatal care. During the WCC, the pediatrician performed the newborn hearing screen, HepB vaccine, vitamin K, eye ointment, and newborn blood draws. All of this would typically be performed immediately post birth. Would an additional E/M LOS be supported with the WCC? Also, what would be the best fit Dx code? I was thinking P00.89, but the mother didn't have any "conditions" other than lack of prenatal care due to personal reasons. This is my first encounter with something like this. Any advice is appreciated!
