Matern care for damag to fts from viral dis in mother, fts4

This code signifies maternal care provided due to a suspected or confirmed viral infection in the mother that is believed to have caused damage to the fetus. Specifically, it indicates that the fourth fetus in a multiple gestation pregnancy is the one affected. This encompasses situations where the mother's viral illness, such as cytomegalovirus, rubella, or Zika, poses a risk of congenital anomalies or other adverse outcomes for the developing fetus.

Use this code when documentation clearly indicates maternal care for a viral infection with suspected fetal damage, and the specific fetus affected is identified as the fourth. This applies to scenarios where diagnostic imaging, laboratory tests, or clinical assessment suggest a viral etiology for fetal abnormalities or compromise. Supporting documentation would include physician notes detailing the maternal viral infection, the suspected fetal damage, and the identification of the affected fetus within a multiple gestation.

• Ensure the medical record explicitly identifies the affected fetus as the fourth in a multiple gestation.
• Sequence this code as a secondary diagnosis following the code for the specific maternal viral infection (e.g., B06.8 for Rubella).
• Do not use this code if the maternal viral infection is not suspected of causing fetal damage, or if the specific fetus affected is not clearly documented.
