Mat care cnsl malf/damag fts, agenesis corpus callosum, fts3

This code signifies maternal care provided due to a suspected or confirmed diagnosis of agenesis of the corpus callosum (ACC) in a fetus, specifically when the pregnancy is in the third trimester. ACC is a congenital brain malformation where the corpus callosum, the band of nerve fibers connecting the two hemispheres of the brain, is partially or completely absent. This code indicates the mother is receiving specialized care related to this fetal condition.

Use this code when documentation clearly indicates maternal care for a fetus diagnosed with or suspected of having agenesis of the corpus callosum, and the pregnancy has progressed to the third trimester. This would typically be supported by ultrasound reports, fetal MRI findings, and physician notes detailing the management plan for the fetal anomaly.

• Ensure the documentation specifies "agenesis of the corpus callosum" and not a more general CNS malformation.
• Verify the gestational age to confirm the third trimester (28 weeks 0 days to 40 weeks 6 days).
• This code is for maternal care; the fetal condition itself would be coded separately if applicable for the newborn record.
