Term delivery w preterm labor, second trimester, unsp

This code describes a delivery that occurs at term (37 weeks 0 days gestation or more) in a patient who experienced preterm labor during the second trimester (14 weeks 0 days to 27 weeks 6 days gestation). The preterm labor did not result in a preterm birth, but rather the pregnancy continued to term.

Use this code when documentation clearly indicates a history of preterm labor occurring specifically in the second trimester, followed by a delivery that reached full term. This code is appropriate when the preterm labor was successfully arrested, and the pregnancy continued to term.

• Ensure documentation specifies "term delivery" and "preterm labor in the second trimester."
• Do not use this code if the delivery was preterm, even if preterm labor occurred in the second trimester.
• Sequence this code as a secondary diagnosis, following the code for the outcome of delivery (e.g., Z37.0 for single live birth).
