Maternal care for damage to fetus by radiation, fetus 3

This code signifies that a pregnant patient is receiving medical attention due to concerns that the fetus has been harmed by radiation exposure. This damage is suspected, not confirmed, and specifically refers to the third fetus in a multiple gestation pregnancy. The care is focused on monitoring and managing the potential effects of radiation on fetal development.

This code is appropriate when a pregnant patient, carrying triplets or more, has a documented history or suspected exposure to radiation during pregnancy, and there is clinical concern for fetal damage in the third fetus. Documentation should clearly indicate the radiation exposure, the specific fetus affected (e.g., "fetus C" or "fetus 3"), and the ongoing maternal care related to this suspicion.

• Always ensure the documentation specifies "fetus 3" in a multiple gestation to justify this specific subcategory.
• Do not use this code if fetal damage from radiation is confirmed; instead, code the specific fetal anomaly.
• Sequence this code as a secondary diagnosis following the primary reason for the encounter if the maternal care is not the sole focus.
