Mat care other fetl abnlt and damag, fetal card anomal, fts1

This code signifies maternal care provided due to a suspected or confirmed cardiac anomaly in the first fetus of a multiple gestation, or in a singleton pregnancy. It indicates that the mother is receiving specialized obstetric management because of a fetal heart defect.

Apply this code when documentation specifies maternal care for a fetus diagnosed with or suspected of having a cardiac anomaly, such as a septal defect, hypoplastic left heart syndrome, or tetralogy of Fallot. This code is appropriate when the fetal cardiac issue is the primary reason for the specialized maternal care.

• Ensure documentation clearly identifies the specific cardiac anomaly and confirms it pertains to "fetus 1" if a multiple gestation.
• Do not use this code if the fetal anomaly is not cardiac in nature; refer to other O35 subcategories.
• Sequence this code as a secondary diagnosis following the code for the specific fetal cardiac anomaly (e.g., Q20-Q28 series).
