Maternal care for hydrops fetalis, second trimester, fetus 2

This code signifies ongoing medical supervision and management provided to a pregnant patient due to the presence of hydrops fetalis in the second fetus of a multiple gestation pregnancy. 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. This code specifically applies when the condition is identified and managed during the second trimester.

Use this code when documentation clearly indicates maternal care is being provided for hydrops fetalis affecting the second fetus in a multiple gestation, and the gestational age falls within the second trimester (weeks 13 through 27+6 days). This would typically be supported by ultrasound reports confirming hydrops in fetus 2, physician notes detailing ongoing monitoring, diagnostic tests, or interventions related to the condition.

• Ensure the documentation specifies "fetus 2" and not fetus 1 or an unspecified fetus.
• Verify the gestational age falls within the second trimester for accurate trimester assignment.
• Code any underlying maternal or fetal conditions causing the hydrops fetalis in addition to this code.
