(A 28-year-old woman who is 36 weeks pregnant withdichorionic/diamniotic twinsdeliveredboth babies vaginally.

Formultiple gestation vaginal deliveries, CPT global obstetric care is generally reported as the global code for thefirst fetus(here59400: antepartum + vaginal delivery + postpartum), and an additionaldelivery-onlycode for each additional fetus (here59409) with an appropriate modifier (commonly-51in exam-style choices). You donotreport59400 twicebecause the global package is not duplicated for each baby; only the additional delivery service is added for the additional fetus. Diagnosis coding: this is atwin pregnancy, dichorionic/diamniotic, third trimester→O30.043. Delivery outcome for twins →Z37.2, and weeks of gestation →Z3A.36. Because delivery occurred at36 weeks(preterm threshold is < 37 weeks), and the options use thepreterm labor with preterm deliverycategory with fetus identifiers, the correct pairing shown isO60.14X1 and O60.14X2(fetus 1 and fetus 2). Option D is the only one matching correct CPT multiple-delivery structure and appropriate diagnosis set.
