Term delivery w preterm labor, second trimester, oth fetus

This code describes a delivery that occurs at term (37 weeks 0 days gestation or more) despite the onset of preterm labor during the second trimester (14 weeks 0 days to 27 weeks 6 days gestation). This indicates that while preterm labor began, it was successfully arrested, and the pregnancy continued to term, with the "other fetus" modifier indicating a multifetal pregnancy where this specific fetus is not the first-born.

Use this code when documentation clearly indicates a history of preterm labor occurring between 14 weeks 0 days and 27 weeks 6 days gestation, but the delivery ultimately takes place at or after 37 weeks. This code is applicable for a multifetal pregnancy when referring to any fetus after the first-born. Supporting documentation would include notes detailing the preterm labor episode, interventions to arrest labor, and the final gestational age at delivery.

• Ensure the delivery occurred at term, despite the history of preterm labor. Do not use if the delivery was actually preterm.
• This code is specifically for the "other fetus" in a multifetal pregnancy; ensure the correct fetus is being referenced.
• Sequence this code as a secondary diagnosis following the code for the outcome of delivery (e.g., Z37.2 for twins, both liveborn).
