Failed trial of labor, unspecified

This code signifies that a pregnant patient underwent an attempt at vaginal delivery, but the attempt was unsuccessful, and the specific reason for the failure is not documented. It indicates that labor was induced or allowed to progress, but ultimately did not result in a vaginal birth.

Apply this code when documentation clearly states "failed trial of labor" without specifying the cause (e.g., cephalopelvic disproportion, fetal distress, arrest of dilation). This typically occurs when a patient progresses through labor but ultimately requires a Cesarean section due to an unstated or unknown reason for the inability to deliver vaginally.

• Do not use if the specific reason for the failed trial of labor is documented; instead, code the specific complication (e.g., O65.5, O66.0).
• Always sequence this code after the primary obstetric complication or reason for admission, if applicable.
• Ensure documentation explicitly states "failed trial of labor" or similar phrasing indicating an attempted but unsuccessful vaginal delivery without further specificity.
