Rupture of uterus during labor

This code signifies a complete or incomplete tear in the uterine wall that occurs during the process of labor. This serious obstetric complication can involve the uterine muscle, serosa, or extend into the broad ligament, and may or may not involve the fetal membranes.

Assign this code when documentation explicitly states a uterine rupture occurred during labor. This includes spontaneous rupture, rupture of a previous uterine scar (e.g., from a prior C-section), or traumatic rupture during labor. Supporting documentation should detail the timing of the rupture relative to labor onset.

• Differentiate from uterine dehiscence, which is an incomplete separation of a uterine scar without rupture of fetal membranes.
• Do not code with O90.0 (disruption of cesarean delivery wound) as per Excludes1 note, as these are distinct conditions.
• Ensure the documentation specifies "during labor" to accurately assign this code. If rupture occurs before labor, a different code would be appropriate.
