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

This diagnosis code signifies maternal care provided due to a suspected or confirmed diagnosis of holoprosencephaly in a single fetus. Holoprosencephaly is a severe congenital brain malformation characterized by the failure of the prosencephalon (the embryonic forebrain) to properly divide into two cerebral hemispheres. This code indicates that the mother is receiving specialized care specifically because of this fetal condition.

Apply this code when documentation clearly indicates maternal management and monitoring for a fetus diagnosed with or suspected of having holoprosencephaly. This includes antenatal consultations, specialized imaging (e.g., detailed fetal ultrasound, fetal MRI), and counseling related to the fetal anomaly. The documentation should specify "fetus 1" if multiple gestations are present, or if it's a singleton pregnancy.

• Ensure documentation specifies "holoprosencephaly" and not a general CNS malformation to support this specific code.
• Verify the fetal number (fetus 1) is accurately reflected in the medical record.
• Do not use this code for other types of CNS malformations; refer to the appropriate O35 subcategory.
