Maternal care for hydrops fetalis, second trimester, unsp

This code signifies ongoing medical management and monitoring of a pregnant patient during her second trimester due to the diagnosis of hydrops fetalis in the developing fetus. 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, or skin edema.

Apply this code when documentation confirms maternal care for a fetus diagnosed with hydrops fetalis during the second trimester of pregnancy. This includes ongoing surveillance, diagnostic testing, and management strategies aimed at addressing the fetal condition. Documentation should clearly state the trimester and the presence of hydrops fetalis.

• Ensure the medical record explicitly states "second trimester" for accurate code assignment.
• Do not use this code if the hydrops fetalis is due to a specified maternal condition (e.g., O36.21- for immune hydrops).
• Sequence this code as a primary diagnosis when the maternal care for hydrops is the focus of the encounter.
