Matern care for disproprtn of mix matern & fetl origin, fts2

This code signifies maternal care provided when there is a size mismatch between the mother's pelvis and the fetus, specifically for the second twin or multiple, where the cause of the disproportion is attributed to both maternal pelvic factors and fetal size. This can lead to difficulties during labor and delivery.

Use this code when documentation indicates cephalopelvic disproportion (CPD) or fetopelvic disproportion (FPD) for a twin pregnancy, with the second fetus being the focus, and the etiology is clearly described as a combination of maternal and fetal factors. Supporting documentation should include physician notes detailing the disproportion, the specific fetus affected, and the mixed origin.

• Ensure the documentation explicitly states "mixed maternal and fetal origin" for the disproportion.
• Verify this code is applied to the second fetus in a multiple gestation; other codes exist for the first fetus or unspecified fetus.
• This code is typically a secondary diagnosis, with the primary diagnosis often related to the outcome of delivery or the reason for the disproportion.
