Mat care (suspected) cnsl malf/damag fts, microceph, fetus 2

This code signifies maternal care provided when microcephaly is suspected or diagnosed in a fetus. It specifically applies to the second fetus in a multiple gestation pregnancy. This condition involves an abnormally small head circumference, often indicative of underlying central nervous system malformation or damage.

Use this code when a pregnant patient carrying twins (or more) receives care due to concerns or confirmed diagnosis of microcephaly in the second fetus. Documentation should clearly indicate the specific fetus affected (fetus 2) and the reason for maternal care related to this fetal condition. This includes antenatal surveillance, counseling, or management planning.

• Ensure documentation specifies "fetus 2" to differentiate from other fetuses in a multiple gestation.
• Do not use this code for microcephaly in a singleton pregnancy or for other fetal CNS malformations without microcephaly.
• Sequence this code as a secondary diagnosis following the code for the primary reason for the encounter, if applicable.
