Rupture of uterus before onset of labor, unsp trimester

This code signifies a spontaneous or traumatic tearing of the uterine wall occurring prior to the initiation of labor contractions. This rupture can lead to severe hemorrhage, fetal distress, and maternal morbidity or mortality. It represents a critical obstetric emergency.

Apply this code when documentation clearly indicates a uterine rupture in a pregnant patient who has not yet begun labor, regardless of the gestational age. Supporting documentation should include physician notes detailing the rupture event, diagnostic findings (e.g., imaging, surgical findings), and the absence of labor.

• Differentiate from uterine rupture during labor (O71.01) or postpartum (O71.1).
• Ensure documentation specifies "before onset of labor" to accurately assign this code.
• Code any associated maternal complications (e.g., hemorrhage, shock) and fetal complications separately.
