Maternal care for hydrops fetalis, first trimester, fetus 2

This code signifies ongoing medical supervision and management provided to a pregnant patient during her first trimester due to the diagnosis of hydrops fetalis affecting the second fetus in a multiple gestation. Hydrops fetalis is a severe, life-threatening condition characterized by abnormal fluid accumulation in two or more fetal compartments.

Apply this code when documentation confirms maternal care for a multifetal pregnancy where one of the fetuses (specifically fetus 2) has been diagnosed with hydrops fetalis during the first trimester. Supporting documentation would include ultrasound reports detailing the hydrops in fetus 2 and physician notes indicating ongoing maternal management related to this fetal condition.

• Ensure the documentation clearly specifies "fetus 2" and that the care occurred during the "first trimester."
• Do not confuse with codes for hydrops in a single gestation or in other trimesters.
• Sequence this code as a secondary diagnosis following the primary code for the pregnancy, typically from category O09.
