Pretrm prem ROM, onset labor > 24 hours fol rupt, second tri

This code describes a condition where the amniotic sac ruptures prematurely before 37 weeks of gestation, specifically during the second trimester (weeks 13-27), and the onset of labor occurs more than 24 hours after this rupture. This prolonged interval between membrane rupture and labor increases risks of infection and other complications for both mother and fetus.

Use this code when documentation clearly indicates preterm premature rupture of membranes (PPROM) occurring in the second trimester, and a latent period of over 24 hours elapsed before the initiation of labor. This code is appropriate for cases where the patient is admitted for management of PPROM with a delayed onset of labor.

• Ensure the documentation specifies the second trimester and a labor onset greater than 24 hours post-rupture.
• Distinguish from PPROM with labor onset within 24 hours (O42.111) or without labor (O42.119).
• Always sequence this code as the principal diagnosis when it is the reason for the encounter, followed by codes for any associated complications.
