A woman at 36-weeks gestation goes into labor with twins. Fetus 1 is an oblique position, and the decision is made to perform a cesarean section to deliver the twins. The obstetrician who delivered the twins, provided the antepartum care, and will provide the postpartum care.
What CPT® coding is reported for the twin delivery?
The antepartum care and the postpartum care is for the mother, they wouldn't be coded in addition to 59510 as that is a global code-- they are already included in it. Some payers may require modifier 22 appended to indicate the multiple birth.
D REPS ROUTINE OBSTECTRIC CARE WITH BOTH ANTEPARTUM. AND POST
Google results say that the answer is D.
