Mat care cnsl malf/damag fts, anencephaly, fetus 2

This code signifies maternal care provided due to a suspected or confirmed diagnosis of anencephaly in the second fetus of a multiple gestation pregnancy. Anencephaly is a severe congenital neural tube defect characterized by the absence of a major portion of the brain, skull, and scalp. This code specifically addresses the maternal management related to this fetal anomaly.

Use this code when the mother is receiving antenatal care for a pregnancy where the second fetus has been diagnosed with, or is suspected of having, anencephaly. Documentation should clearly indicate the specific fetal anomaly (anencephaly), the gestational age, and that it pertains to the second fetus in a multifetal pregnancy. This code is appropriate for surveillance, counseling, and management decisions related to this condition.

• Ensure documentation specifies "fetus 2" to differentiate from other fetuses in a multiple gestation.
• Do not use this code for other central nervous system malformations; a more specific code within O35.0- should be selected.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is routine prenatal care, or as a primary diagnosis if the encounter is solely for the management of the fetal anomaly.
