Maternal care for hydrops fetalis, third trimester, fetus 4

This code signifies ongoing medical management and surveillance provided to a pregnant patient in her third trimester due to the diagnosis of hydrops fetalis affecting the fourth fetus in a multiple gestation. 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.

Apply this code when the medical record documents active management or monitoring of a third-trimester pregnancy complicated by hydrops fetalis in the fourth fetus. This includes scenarios where interventions are being considered or performed to address the hydrops, or when close observation is required due to the severity of the condition. Documentation should clearly specify the trimester and the affected fetus.

• Ensure the documentation explicitly identifies the third trimester and confirms the diagnosis of hydrops fetalis in the fourth fetus.
• Do not use this code for hydrops identified in earlier trimesters; specific codes exist for those periods.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is related to the management of the pregnancy.
