Term delivery with preterm labor, second trimester, fetus 4

This code describes a delivery occurring at term (37+ weeks gestation) where the labor itself began prematurely during the second trimester (14 weeks 0 days to 27 weeks 6 days gestation). This indicates a prolonged labor process that initiated early but resulted in a full-term birth for the fourth fetus in a multiple gestation pregnancy.

This code is used when documentation clearly indicates that preterm labor was diagnosed and managed during the second trimester, but the actual delivery occurred at term. It is specific to the fourth fetus in a multiple gestation. Documentation should specify the gestational age at the onset of labor and the gestational age at delivery.

• Always sequence this code after the primary obstetric code indicating the type of delivery (e.g., O80 for spontaneous vaginal delivery).
• Ensure the documentation clearly distinguishes between preterm labor onset and term delivery.
• Verify the fetal number for multiple gestations; this code is specific to the fourth fetus.
