Obstructed labor due to deformed pelvis

This code signifies a situation during labor where the baby's descent and delivery are impeded by an abnormally shaped or sized maternal pelvis. This anatomical disproportion prevents the normal progression of labor, often necessitating intervention.

Apply this code when documentation clearly indicates that the mother's pelvic structure is the primary cause of obstructed labor. This typically involves findings such as cephalopelvic disproportion (CPD) due to a contracted or malformed pelvis, leading to failure to progress despite adequate uterine contractions.

• Ensure documentation specifies "deformed pelvis" as the cause of obstruction, not just general CPD.
• Sequence this code as the principal diagnosis when it is the reason for admission or the primary condition treated.
• Do not confuse with obstructed labor due to fetal malposition or malpresentation (O64.-), which are distinct causes of obstruction.
