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

This code signifies maternal care provided when a fetal encephalocele, a type of central nervous system malformation, is suspected or confirmed in a fetus other than the first-listed fetus in a multiple gestation. It indicates that the mother is receiving medical attention specifically due to this identified or suspected fetal anomaly.

Use this code when documentation clearly indicates maternal care for a suspected or diagnosed encephalocele in a non-first fetus. This typically occurs following prenatal imaging (e.g., ultrasound, MRI) that identifies the malformation. The medical record must specify that the encephalocele is in a fetus other than the one designated as Fetus 1.

• Ensure the documentation specifies "other fetus" or identifies the specific fetus (e.g., Fetus B, Fetus 2) with the encephalocele.
• Always assign an additional code from category Z3A to specify the weeks of gestation.
• Distinguish from O35.03X_ for encephalocele in the first fetus.
