Abnormal finding on antenatal screening

This code represents any non-specific abnormal finding identified during routine prenatal screening tests. It indicates that further investigation is warranted due to an atypical result, but a definitive diagnosis has not yet been established. This could include abnormal blood tests, urine tests, or initial ultrasound findings that deviate from normal parameters.

Use this code when documentation indicates an abnormal result from an antenatal screening test, such as an elevated alpha-fetoprotein (AFP), abnormal glucose screening, or an atypical fetal heart rate pattern, without a confirmed diagnosis. It is appropriate for the initial encounter where the abnormal finding is identified and before a specific condition is diagnosed.

• Do not use this code once a definitive diagnosis for the abnormal finding has been established; instead, code the specific condition.
• This code is often a primary diagnosis when the patient is being referred for further evaluation due to the screening result.
• Ensure the medical record clearly states "abnormal finding" or "atypical result" from an antenatal screening test.
