Matern care for damag to fetus from viral dis in mother, oth

This code signifies maternal care provided when there is suspected or confirmed damage to a fetus due to a viral infection in the mother. This specifically applies to situations involving multiple gestations where one fetus is affected by the maternal viral disease. It indicates the mother is receiving monitoring and management related to this fetal complication.

Use this code when a pregnant patient has a documented viral infection (e.g., CMV, rubella, Zika) and there is concern or evidence of its adverse effects on one or more fetuses. Documentation should clearly state the maternal viral infection and the suspected or confirmed fetal damage, particularly in multifetal pregnancies.

• Always sequence this code as a secondary diagnosis following the code for the specific maternal viral infection (e.g., B06.8 for rubella).
• Ensure documentation specifies "other fetus" if applicable, differentiating from O35.3XX0 for a single fetus or unspecified fetus.
• Do not use this code if the fetal damage is due to a non-viral maternal condition; refer to other O35 subcategories.
