Mat care cnsl malf/damag fts, agenesis corpus callosum, fts2

This code signifies maternal care provided due to the diagnosis or suspicion of agenesis of the corpus callosum in a fetus. Agenesis of the corpus callosum is a congenital brain malformation where the structure connecting the two cerebral hemispheres is partially or completely absent. This code specifically applies when the fetus is identified as "fetus 2" in a multiple gestation pregnancy.

Use this code when a pregnant patient is receiving care because ultrasound or other diagnostic imaging has identified or strongly suggested agenesis of the corpus callosum in one of the fetuses, specifically the second fetus. Documentation should clearly indicate the suspected or confirmed fetal anomaly and the specific fetus affected in a multiple gestation.

• Always assign a code from category O30 (Multiple gestation) as a primary diagnosis when using this code.
• Ensure documentation specifies "fetus 2" to support the final character of the code.
• Distinguish from other fetal central nervous system malformations; this code is specific to agenesis of the corpus callosum.
