Pretrm prem ROM, unsp time betw rupt and onset labr, 2nd tri

This code signifies the spontaneous rupture of the amniotic sac before the onset of labor, occurring during the second trimester of pregnancy, where the time interval between the rupture and labor onset is not documented. It indicates a premature rupture of membranes (PROM) that is specifically preterm and occurs between 14 weeks 0 days and 27 weeks 6 days of gestation.

Use this code when documentation confirms preterm premature rupture of membranes (PPROM) in the second trimester, and the medical record does not specify the duration between the membrane rupture and the initiation of labor. This code is appropriate when the provider's notes clearly state "PPROM second trimester" without further time-related detail.

• Ensure the documentation explicitly states "second trimester" for the timing of the PPROM.
• Do not use this code if the time interval between rupture and labor onset is specified (e.g., "less than 24 hours" or "24 hours or more").
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, followed by codes for any associated complications.
