Full-term premature ROM, onset labor > 24 hours fol rupture

This code signifies a pregnancy where the amniotic sac ruptured at term (37+ weeks gestation) and labor did not spontaneously begin until more than 24 hours after the rupture occurred. This condition increases the risk of maternal and fetal infection due to the prolonged exposure of the uterus to the external environment.

Apply this code when documentation clearly indicates a full-term pregnancy with premature rupture of membranes (PROM) and a latent period exceeding 24 hours between rupture and the onset of active labor. This is typically supported by obstetric notes detailing the time of membrane rupture and the subsequent initiation of labor.

• Ensure documentation specifies "full-term" and a latent period "more than 24 hours" to differentiate from other PROM codes.
• Do not use if labor began within 24 hours of membrane rupture, or if the rupture occurred preterm.
• Sequence this code as a secondary diagnosis when an outcome of delivery code (e.g., O80-O82) is the primary.
