Maternal care for hereditary disease in fetus, fetus 4

This code signifies antenatal care provided to a pregnant patient when there is a suspicion or confirmed diagnosis of a hereditary disease affecting the fourth fetus in a multiple gestation pregnancy. This includes situations where the fetus is at risk due to family history, genetic screening results, or other clinical indicators suggesting a heritable condition.

Use this code when the medical record clearly documents maternal care specifically addressing a suspected or confirmed hereditary disease in the fourth fetus. This typically involves genetic counseling, specialized prenatal diagnostic tests (e.g., amniocentesis, chorionic villus sampling), or monitoring for manifestations of the suspected condition.

• Ensure documentation specifies "fetus 4" to justify the use of this specific character.
• This code is for maternal care; do not use it for the diagnosis of the hereditary disease itself in the fetus.
• Sequence this code as a secondary diagnosis, with the primary diagnosis reflecting the reason for the encounter (e.g., routine prenatal visit, genetic counseling).
