Term delivery with preterm labor, third trimester, fetus 4

This code signifies a delivery that occurred at term (37 weeks 0 days gestation or later) despite the presence of preterm labor (contractions causing cervical change before 37 weeks gestation) during the third trimester. It specifically identifies the fourth fetus in a multiple gestation pregnancy. The key distinction is that while preterm labor was experienced, the delivery itself was not preterm.

This code is appropriate when a patient experiences preterm labor in the third trimester but ultimately delivers at term. Documentation should clearly indicate preterm labor activity (e.g., cervical dilation/effacement, regular contractions) and the gestational age at delivery confirming it was at term. This code is used for the fourth fetus in a multifetal pregnancy.

• Ensure documentation explicitly states "term delivery" despite "preterm labor."
• Verify the fetal number (fourth fetus) in cases of multiple gestations.
• Do not confuse with codes for actual preterm delivery (O60.1x) or false labor (O47.0x).
