Abn chromsoml and genetic find on antenat screen of mother

This code indicates an abnormal result from a prenatal screening test that suggests a chromosomal abnormality or genetic disorder in the fetus. This finding is identified during the antenatal period through non-invasive or minimally invasive screening methods performed on the mother. It does not represent a confirmed diagnosis of a fetal condition, but rather an indication requiring further investigation.

Use this code when documentation indicates an abnormal finding from a maternal antenatal screening test (e.g., NIPT, quad screen, first-trimester screen) that points to a potential chromosomal or genetic issue in the fetus. This code is appropriate when the abnormal finding is noted, but a definitive fetal diagnosis has not yet been established.

• Do not use this code for confirmed fetal chromosomal abnormalities; instead, use codes from Chapter 16 (P00-P96) or Chapter 17 (Q00-Q99) as appropriate.
• Always sequence this code after the primary reason for the encounter, if applicable, such as routine antenatal care (Z34.-).
• Ensure documentation clearly states the abnormal screening result and that it pertains to a chromosomal or genetic finding.
