Obstructed labor due to abnlt of maternal pelvic organs

This diagnosis code signifies a labor dystocia (difficult labor) caused by an anatomical or structural anomaly of the mother's pelvic organs, which physically impedes the descent and passage of the fetus. This obstruction is due to a maternal factor, not fetal size or position.

This code is appropriate when documentation clearly indicates that the mother's pelvic structure, such as a malformed or contracted pelvis, is the primary reason for obstructed labor. Supporting documentation would include physician notes detailing pelvic measurements, imaging findings (e.g., pelvimetry), and the clinical assessment of labor progression being hindered by the maternal pelvis.

• Differentiate from obstructed labor due to fetal causes (e.g., large fetus, malpresentation) or uterine inertia.
• Always sequence this code as the principal diagnosis if it is the primary reason for the admission or encounter for delivery.
• Ensure documentation specifies the abnormality of the maternal pelvic organs, not just "obstructed labor."
