Preterm labor second tri w preterm del second tri, fetus 3

This code describes a pregnancy complicated by the onset of labor and subsequent delivery during the second trimester (weeks 14 0/7 through 27 6/7 of gestation). Specifically, it indicates that the preterm labor resulted in a preterm delivery, and the code specifies this outcome for the third fetus in a multiple gestation.

Use this code when documentation clearly indicates a patient experienced preterm labor that progressed to a preterm delivery within the second trimester. This code is appropriate for the third fetus in a multifetal pregnancy. Supporting documentation should include gestational age at onset of labor and delivery, and the number of fetuses.

• Ensure the gestational age at delivery falls within the second trimester (14 0/7 to 27 6/7 weeks).
• Verify this code is assigned to the third fetus in a multiple gestation; separate codes are needed for other fetuses.
• Distinguish from codes for preterm labor without delivery or preterm labor with delivery in other trimesters.
