Maternal care for hydrops fetalis, third trimester, fetus 3

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

Use this code when documentation confirms maternal care for a diagnosed case of hydrops fetalis in the third trimester of a multiple pregnancy, specifically identifying the third fetus as affected. This code is appropriate for encounters where the mother is receiving treatment or close surveillance for this fetal condition. Documentation should clearly specify the trimester and the affected fetus number.

• Ensure documentation explicitly states "third trimester" and identifies the "third fetus" as having hydrops fetalis.
• Do not use this code if the hydrops fetalis is due to a specific maternal condition (e.g., Rh isoimmunization); instead, code the underlying maternal condition first.
• Always sequence this code after any codes for the underlying cause of the hydrops fetalis, if known and applicable to the mother's care.
