Mat care cnsl malf/damag fts, anencephaly, fetus 4

This code signifies maternal care provided due to the fetus having a suspected or confirmed central nervous system malformation, specifically anencephaly. It indicates that this is the fourth fetus being managed in a multiple gestation pregnancy.

Apply this code when a pregnant patient is receiving care because one of the fetuses, identified as the fourth, has been diagnosed with or is suspected of having anencephaly. Documentation should clearly state the fetal anomaly, the specific fetus affected (e.g., "fetus D" or "fourth fetus"), and the ongoing maternal management related to this condition.

• Ensure documentation specifies "fetus 4" in cases of multiple gestation; otherwise, an unspecified fetus code (O35.02X0) may be more appropriate.
• This code is for maternal care; a separate code for the fetal condition itself (e.g., Q00.0 for anencephaly) would be used on the infant's record after birth.
• Sequence this code as a primary diagnosis when the anencephaly is the main reason for the encounter, or as a secondary diagnosis when it's an complicating factor.
