Rupture of uterus before onset of labor, second trimester

This code signifies a spontaneous tear or dehiscence of the uterine wall occurring during the second trimester of pregnancy, prior to the initiation of labor contractions. This is a serious obstetric complication that can lead to significant maternal and fetal morbidity or mortality.

Apply this code when documentation clearly indicates a uterine rupture in a pregnant patient between 14 weeks 0 days and 27 weeks 6 days gestation, and the rupture occurred before the onset of labor. Supporting documentation should include operative reports, physician notes detailing the rupture event, and gestational age at the time of rupture.

• Ensure the documentation specifies "before onset of labor" to differentiate from ruptures occurring during labor.
• Verify the gestational age falls within the second trimester (14-27 weeks).
• Code any associated fetal complications or maternal conditions separately.
