Maternal care for hydrops fetalis, unsp trimester, fetus 4

This code signifies maternal care provided due to the presence of hydrops fetalis in the fourth fetus of a multiple gestation pregnancy. Hydrops fetalis is a severe, life-threatening condition characterized by abnormal fluid accumulation in two or more fetal compartments, such as ascites, pleural effusion, pericardial effusion, and skin edema.

Use this code when a pregnant patient is receiving medical management or monitoring specifically because one of her fetuses (the fourth in a multiple pregnancy) has been diagnosed with hydrops fetalis, and the gestational age is not specified. Documentation should clearly indicate the diagnosis of hydrops fetalis in the fourth fetus and the ongoing maternal care related to this fetal condition.

• Ensure documentation specifies "fetus 4" to justify the final character. If the specific fetus number is unknown, an unspecified fetus code should be used.
• This code indicates maternal care for the fetal condition; do not use for coding the fetal condition itself on the fetal record.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is related to the management of the pregnancy with this complication.
