Maternal care for hydrops fetalis, second trimester, fetus 4

This code signifies ongoing medical supervision and management provided to a pregnant patient whose developing fetus, in the second trimester, has been diagnosed with hydrops fetalis. 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. This specific code indicates that the care is directed towards the fourth fetus in a multiple gestation pregnancy.

Use this code when documentation clearly indicates maternal care for a diagnosed case of hydrops fetalis affecting the fourth fetus during the second trimester of pregnancy. This typically involves specialized monitoring, diagnostic tests (e.g., ultrasound, amniocentesis), and potential interventions aimed at managing the condition. Supporting documentation should specify the trimester, the diagnosis of hydrops fetalis, and the identification of the affected fetus (fetus 4).

• Ensure the medical record explicitly states "second trimester" and identifies "fetus 4" for accurate code assignment.
• Do not confuse this with codes for hydrops fetalis affecting other fetuses (e.g., fetus 1, 2, 3) or unspecified fetuses.
• Always sequence this code as a secondary diagnosis, following the primary code for the specific type of hydrops fetalis (e.g., nonimmune, immune).
