Mat care (suspected) cnsl malf/damag fts, hydroceph, fetus 2

This code signifies ongoing maternal medical management and surveillance due to a suspected or confirmed diagnosis of fetal hydrocephaly. It indicates that the hydrocephalus is considered a central nervous system malformation or damage within the developing fetus. The "2" in the code specifies that this diagnosis pertains to the second fetus in a multiple gestation pregnancy.

Apply this code when a pregnant patient is receiving care because imaging (e.g., ultrasound, MRI) or genetic testing has identified hydrocephaly in fetus 2. Documentation should clearly state the suspected or confirmed hydrocephaly in the second fetus and the maternal care being provided as a result. This code is appropriate for antenatal visits focused on monitoring the fetal condition.

• Ensure documentation explicitly identifies the affected fetus as "fetus 2" in a multiple gestation.
• Do not use this code if the hydrocephaly is definitively ruled out; instead, use codes for normal pregnancy surveillance.
• Sequence this code as a secondary diagnosis following the primary code for the encounter (e.g., routine prenatal visit).
