Mat care cnsl malf/damag fts, anencephaly, other fetus

This code signifies maternal care provided due to a suspected or confirmed central nervous system malformation or damage in a fetus, specifically anencephaly, when it affects an "other fetus" in a multiple gestation pregnancy. It indicates that the mother is receiving medical attention because one of the fetuses has this severe congenital anomaly.

Use this code when documentation indicates maternal management for a fetus diagnosed with or suspected of having anencephaly, and the pregnancy involves multiple gestations where this particular fetus is not the primary one. Supporting documentation would include ultrasound reports, fetal anomaly scans, and physician notes detailing the diagnosis and ongoing maternal care.

• Ensure the documentation clearly specifies anencephaly and confirms it affects an "other fetus" in a multiple gestation.
• Do not use this code for a singleton pregnancy or if the CNS malformation is not anencephaly.
• Sequence this code as a secondary diagnosis following the primary reason for the encounter, if applicable, or as the primary diagnosis if the maternal care is solely focused on the fetal anomaly.
