O28.9
ICD-10-CMUnspecified abnormal findings on antenatal screening of mother
This code signifies an abnormal result from a screening test performed during pregnancy, where the specific nature of the abnormality is not documented. It indicates that further investigation may be warranted due to a non-specific finding identified during routine antenatal care.
Use this code when the medical record indicates an abnormal antenatal screening result, but the provider has not specified the exact finding or the specific test that yielded the abnormality. Documentation supporting its use would include a note stating "abnormal antenatal screen" without further detail.
