Mat care chromosomal abnlt in fetus, unspecified, fetus 2

This code signifies a pregnancy where the mother is receiving medical attention due to a concern for a chromosomal abnormality in the second fetus of a multiple gestation. This concern is not yet confirmed but is under investigation or surveillance. It indicates a potential genetic issue affecting the developing fetus.

Use this code when documentation indicates maternal care for a suspected chromosomal abnormality in fetus 2, without further specification of the type of abnormality. This would be supported by findings such as abnormal prenatal screening tests (e.g., NIPT, quad screen), ultrasound markers suggestive of aneuploidy, or a family history prompting genetic counseling and further evaluation.

• Requires documentation specifying "fetus 2" in a multiple gestation.
• Do not use if a specific chromosomal abnormality has been definitively diagnosed; instead, code the specific condition.
• Sequence as a primary diagnosis when the maternal care is primarily focused on the suspected fetal condition.
