Term delivery with preterm labor, unsp trimester, fetus 1

This code describes a delivery that occurs at term (37 weeks 0 days gestation or later) but was preceded by the onset of preterm labor (labor before 37 weeks 0 days gestation). It indicates that the specific trimester in which the preterm labor occurred is not documented. This code applies to the first fetus in a multiple gestation or the only fetus in a singleton pregnancy.

Use this code when a patient experiences preterm labor but ultimately delivers at term, and the documentation does not specify the trimester of the preterm labor onset. This scenario often involves successful tocolysis or spontaneous cessation of preterm contractions, followed by a term delivery. Documentation should clearly state "preterm labor" and "term delivery."

• Ensure documentation explicitly states "term delivery" despite the history of "preterm labor."
• Do not use this code if the delivery itself was preterm; instead, use codes from O60.0 or O60.1.
• Verify the fetus number (X1 for fetus 1) for multiple gestations; adjust the 7th character accordingly for subsequent fetuses.
