Mat care cnsl malf/damag fts, anencephaly, fetus 1

This code signifies maternal care provided when anencephaly is suspected or confirmed in a single fetus. Anencephaly is a severe congenital neural tube defect characterized by the absence of a major portion of the brain, skull, and scalp. This code is used to track the maternal management related to this specific fetal anomaly.

Apply this code when a pregnant patient is receiving care due to a diagnosis or suspicion of anencephaly in a singleton pregnancy. Documentation should clearly indicate the fetal anomaly (anencephaly), the gestational status (singleton), and the ongoing maternal care or surveillance related to this condition. This often arises from ultrasound findings or genetic testing.

• Ensure documentation specifies "anencephaly" and not a general CNS malformation.
• Verify the fetal count; this code is specific to a singleton pregnancy.
• Sequence this code as a primary diagnosis when the anencephaly is the primary reason for the encounter.
