Matern care for disproprtn of mix matern & fetl origin, fts4

This code signifies maternal care for a pregnancy where the size relationship between the mother's pelvis and the fetus is abnormal due to a combination of maternal pelvic issues and fetal size or presentation issues. This disproportion creates an obstruction to labor and delivery. Specifically, this code applies when the fourth fetus in a multiple gestation is affected.

Use this code when documentation indicates cephalopelvic disproportion (CPD) or fetopelvic disproportion (FPD) resulting from both maternal factors (e.g., small pelvis) and fetal factors (e.g., large fetus, abnormal presentation) in a multifetal pregnancy, and the specific fetus impacted is identified as the fourth. Supporting documentation should clearly state the mixed origin of the disproportion and specify the affected fetus.

• Ensure the documentation explicitly states "mixed maternal and fetal origin" for the disproportion, not solely maternal or fetal.
• Verify the fetal number (4) is accurately identified in the medical record for multiple gestations.
• This code is typically a primary diagnosis when the disproportion is the reason for admission or intervention, often leading to a C-section.
