Term delivery with preterm labor, unsp trimester, fetus 2

This code describes a delivery that occurs at term (37 weeks 0 days gestation or later) despite the presence of preterm labor contractions. It specifically applies to the second fetus in a multiple gestation pregnancy where the trimester of the preterm labor is not documented.

Assign this code when a patient experiences preterm labor but ultimately delivers at term, and the documentation specifies this applies to the second fetus. This code is appropriate when the medical record does not indicate the specific trimester in which the preterm labor occurred.

• Ensure documentation clearly specifies "fetus 2" for this code to be appropriate.
• Do not use if the delivery was actually preterm; this code is for term delivery with a history of preterm labor.
• Always sequence this code after the primary code for the outcome of the delivery (e.g., Z37.2 for twins, both liveborn).
