Maternal care for disproprtn due to inlet contrctn of pelvis

This code signifies maternal care provided when the mother's pelvic inlet is too small or abnormally shaped, preventing the fetal head from engaging or passing through, leading to a disproportion between the fetal size and the maternal pelvis. This condition often necessitates careful monitoring and may result in a planned or emergent cesarean section.

Apply this code when documentation clearly indicates that the maternal pelvic inlet is contracted, causing cephalopelvic disproportion (CPD) or fetopelvic disproportion (FPD). This diagnosis is typically made during pregnancy, often in the third trimester, or during labor when engagement or descent is arrested due to the pelvic structure.

• Ensure the documentation specifically states "inlet contraction" as the cause of disproportion, not just general CPD.
• Distinguish this from other forms of pelvic contraction (e.g., outlet contraction) or disproportion due to fetal issues (e.g., macrosomia).
• Sequence this code as a principal diagnosis when it is the primary reason for the encounter, or as a secondary diagnosis when it complicates the pregnancy or delivery.
