Term delivery with preterm labor, unsp trimester, fetus 4

This code signifies a delivery that occurred at term (37 weeks 0 days gestation or later) despite the presence of preterm labor contractions. It indicates that the preterm labor did not result in a preterm birth for the fourth fetus in a multiple gestation pregnancy.

This code is appropriate when a patient experiences preterm labor but ultimately delivers at term, and the documentation specifically identifies this as the fourth fetus. Documentation should clearly state "term delivery" and "preterm labor," along with the fetal number.

• Ensure documentation specifies "fetus 4" for accurate assignment in multiple gestations.
• Do not use this code if the delivery was actually preterm; instead, select a code from O42.x or O60.1x.
• Sequence this code as a secondary diagnosis following the primary code for the outcome of delivery (e.g., Z37.x for outcome of delivery).
