Preterm labor third tri w preterm del third tri, fetus 3

This code signifies the occurrence of labor contractions leading to cervical changes and subsequent delivery of a fetus during the third trimester of pregnancy, specifically for the third fetus in a multiple gestation. It indicates that the delivery occurred prematurely, prior to 37 completed weeks of gestation, for this particular fetus.

Apply this code when documentation clearly states preterm labor resulting in a preterm delivery for the third fetus in a multifetal pregnancy during the third trimester. This typically applies to scenarios where the patient presents with regular uterine contractions and progressive cervical effacement or dilation, culminating in the birth of the third twin or triplet before full term.

• Ensure documentation specifies "fetus 3" for accurate assignment, as separate codes exist for other fetal positions.
• Verify the gestational age at delivery to confirm it falls within the preterm range (before 37 weeks).
• Do not use this code if the labor was term or if the delivery was not preterm.
