Preterm labor third tri w preterm del third tri, fetus 4

This code signifies the occurrence of labor contractions leading to cervical changes and delivery before 37 weeks of gestation, specifically when both labor and delivery happen during the third trimester. It indicates that the pregnancy resulted in the birth of the fourth fetus in a multifetal gestation.

Apply this code when a pregnant patient experiences preterm labor and subsequently delivers in the third trimester (28 weeks 0 days to 36 weeks 6 days gestation), and the documentation specifies this delivery as the fourth fetus. Supporting documentation should clearly state preterm labor, preterm delivery, the gestational age at delivery, and the fetal order in a multiple gestation.

• Always confirm the specific fetus number being delivered in a multiple gestation; this code is for the fourth fetus.
• Ensure the documentation explicitly states both preterm labor and preterm delivery occurred in the third trimester.
• Sequence this code as the principal diagnosis when the reason for the encounter is the preterm labor and delivery.
