Matern care for damag to fts from viral dis in mother, fts1

This code signifies antenatal care provided to a pregnant patient when there is a suspicion or confirmed diagnosis of fetal damage resulting from a maternal viral infection. It indicates that the fetus is identified as a singleton pregnancy. This includes monitoring, diagnostic testing, and management strategies aimed at mitigating or assessing the impact of the viral exposure on the developing fetus.

Apply this code when a pregnant patient receives care due to concerns about fetal anomalies or complications stemming from a maternal viral illness, such as Zika, CMV, rubella, or parvovirus B19. Documentation should clearly state the maternal viral infection and the suspected or confirmed fetal involvement, along with the singleton status of the pregnancy. This code is appropriate for encounters focused on assessing fetal well-being in this context.

• Always sequence this code as a secondary diagnosis, following the code for the specific maternal viral infection (e.g., O98.5- for other viral diseases complicating pregnancy).
• Ensure documentation explicitly states "fetus 1" or confirms a singleton pregnancy; otherwise, an unspecified fetus code (O35.3XX0) or other fetus codes (O35.3XX2, O35.3XX3, O35.3XX4, O35.3XX5, O35.3XX9) may be more appropriate.
• Do not use this code if the fetal damage is confirmed to be from a non-viral cause; instead, select the appropriate O35.- code for the specific cause.
