Matern care for damag to fts from viral dis in mother, fts3

This code signifies maternal care provided due to suspected or confirmed fetal damage resulting from a viral infection in the mother, specifically when the fetus is identified as a triplet. It indicates that the maternal condition is impacting the third fetus in a multiple gestation pregnancy.

Use this code when documentation specifies maternal care for a viral disease (e.g., Zika, CMV, rubella) that is suspected or known to have caused damage to one of the fetuses in a triplet pregnancy. The medical record must clearly identify the affected fetus as the third in the gestation.

• Always sequence this code after the primary code for the maternal viral infection.
• Ensure documentation specifies "fetus 3" or similar identification for the affected fetus in a triplet pregnancy.
• Do not use this code for damage from non-viral maternal conditions; refer to other O35 subcategories.
