Obstructed labor due to generally contracted pelvis

This diagnosis code signifies a specific type of obstructed labor where the passage of the fetus through the birth canal is impeded by a pelvis that is uniformly smaller than average in all dimensions. This general contraction prevents normal fetal descent and progression of labor.

Apply this code when documentation clearly indicates obstructed labor caused by a generally contracted pelvis, often identified through pelvimetry or clinical assessment. This typically occurs when the maternal pelvis is too small for the fetal head or body to pass through, leading to labor dystocia.

• Ensure documentation specifies "generally contracted pelvis" as the cause of obstruction, not just a narrow or small pelvis.
• Do not confuse with other types of cephalopelvic disproportion (CPD) where the contraction is not general, such as inlet or outlet contraction.
• Always sequence this code as the principal diagnosis when it is the reason for the encounter, followed by codes for the outcome of delivery if applicable.
