Term delivery with preterm labor, third trimester, fetus 1

This code describes a pregnancy where a patient experiences preterm labor (contractions causing cervical changes) during the third trimester, but ultimately delivers at term (37 weeks gestation or later). It specifically applies to the first fetus in a multiple gestation or the only fetus in a singleton pregnancy.

Use this code when documentation indicates a diagnosis of preterm labor occurring after 28 weeks gestation, but the delivery itself occurs at 37 weeks or more. Supporting documentation should clearly state both the occurrence of preterm labor and the term delivery outcome for the specified fetus.

• Always sequence this code as a secondary diagnosis, following the code for the principal complication of pregnancy, childbirth, and the puerperium (e.g., O42.x for premature rupture of membranes).
• Ensure the documentation specifies "fetus 1" if applicable, or that it's a singleton pregnancy, to avoid confusion with codes for other fetuses.
• Do not use this code if the delivery was actually preterm; instead, select the appropriate preterm delivery code (O60.0x or O60.1x).
