Matern care for damag to fts from viral dis in mother, fts5

This code signifies maternal care provided due to a confirmed or suspected viral infection in the mother that has caused, or is suspected of causing, damage to the fetus. The fifth character '5' indicates that the fetus being monitored or affected is the fifth in a multiple gestation pregnancy. This code is used when the maternal viral infection poses a risk of congenital anomalies or other adverse fetal outcomes.

Use this code when a pregnant patient with a viral infection (e.g., CMV, Rubella, Zika) is receiving care specifically for the potential impact of that infection on her fifth fetus. Documentation should clearly state the maternal viral infection, the concern for fetal damage, and specify that the care is directed towards the fifth fetus in a multiple gestation. This code is appropriate for antenatal surveillance, diagnostic testing, or management related to the fetal risk.

• Always sequence this code as a secondary diagnosis, following the code for the specific maternal viral infection (e.g., B06.8 for other specified rubella).
• Ensure the medical record explicitly identifies the fetus as the fifth in a multiple gestation to justify the '5' fifth character.
• Do not use this code if the fetal damage is confirmed to be from a non-viral cause or if the mother's viral infection is not suspected of affecting the fetus.
