Mat care oth fetl abnlt & damag, fetl upr extrm anomal, fts4

This code signifies ongoing maternal medical management due to the identification or suspicion of an anomaly affecting the upper extremities of the fourth fetus in a multiple gestation pregnancy. This includes conditions such as hypoplasia, agenesis, or malformations of the hands, wrists, forearms, or arms. The care provided is specifically for monitoring and addressing the implications of this fetal abnormality.

Apply this code when documentation indicates maternal care is being provided for a diagnosed or suspected congenital anomaly of the upper extremities in the fourth fetus. This typically arises from prenatal ultrasound findings or other diagnostic imaging. Supporting documentation should clearly specify the fetal anomaly, the affected upper extremities, and the fetus number.

• Ensure the documentation explicitly identifies the anomaly as affecting the upper extremities and specifies "fetus 4."
• Do not use this code for anomalies of the lower extremities or other body parts; specific codes exist for those conditions.
• Sequence this code as a secondary diagnosis following the primary reason for the encounter, such as routine prenatal care (Z34.xx).
