Mat care (suspected) cnsl malf/damag fts, hydroceph, fetus 1

This code signifies ongoing maternal care during pregnancy due to the suspicion or confirmed diagnosis of hydrocephaly in the first fetus of a multiple gestation. It indicates that the mother is receiving specialized monitoring and management because of this specific fetal central nervous system malformation.

Use this code when documentation clearly indicates maternal care for a fetus diagnosed with or suspected of having hydrocephaly. This applies to the first fetus in a multiple pregnancy. Supporting documentation includes ultrasound reports, fetal MRI findings, and physician notes detailing the fetal condition and the maternal management plan.

• Ensure the documentation specifies "hydrocephaly" and not a general CNS malformation, as more specific codes exist.
• Verify that the fetus in question is identified as "fetus 1" in a multiple gestation.
• This code is for maternal care; do not use it for the fetal condition itself, which would be coded separately from Chapter 16.
