Maternal care for hydrops fetalis, first trimester, fetus 1

This code signifies ongoing medical supervision and management provided to a pregnant patient due to the diagnosis of hydrops fetalis in the first trimester, specifically affecting the first identified fetus. 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 fetus diagnosed with hydrops fetalis during the first trimester (up to 13 weeks and 6 days gestation). Supporting documentation should include ultrasound reports detailing fetal fluid accumulation and physician notes indicating active management or monitoring related to this condition.

• Ensure the trimester is clearly documented as "first trimester" for accurate code assignment.
• Verify that the documentation specifies "fetus 1" if multiple gestations are present; otherwise, use the unspecified fetus code.
• This code is for maternal care due to the fetal condition, not for the fetal condition itself.
