Abnormal findings on antenatal screening of mother (O28)
The O28 ICD-10 codes are used to classify various abnormal findings on antenatal screening of the mother, which help identify potential complications during pregnancy. These codes cover a range of screening abnormalities detected through blood tests, ultrasounds, cytology, and genetic assessments.
Each subcode specifies a distinct type of abnormal antenatal result: O28.0 relates to abnormal hematological findings, often involving blood chemistry irregularities affecting the fetus. O28.1 covers abnormal biochemical results, while O28.2 identifies abnormal cytological findings such as atypical fetal cells. O28.3 refers to unusual ultrasound findings including fetal ventriculomegaly or increased nuchal translucency. Abnormal radiological findings are classified under O28.4. Genetic or chromosomal anomalies, like Down syndrome screening abnormalities, are captured by O28.5. Additionally, O28.8 includes other atypical findings such as cardiotocogram issues, and O28.9 is used when the abnormality is unspecified. These codes assist healthcare professionals and coders in accurately documenting maternal screening results during pregnancy.

Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
