Abnormal cytolog finding on antenatal screening of mother

This code signifies an abnormal result from a cytological examination performed during the antenatal period. This typically refers to atypical cellular findings on a Pap test or other cervical screening conducted on a pregnant patient. It indicates a need for further investigation or monitoring, but does not specify the definitive diagnosis.

Assign this code when documentation indicates an abnormal Pap smear or other cervical cytology screening result obtained during pregnancy, prior to delivery. This code is appropriate when the specific nature of the abnormality (e.g., ASCUS, LSIL, HSIL) is not yet definitively diagnosed or is not the primary focus of the encounter. Supporting documentation includes pathology reports and physician notes detailing the abnormal screening finding.

• Do not use this code for a definitive diagnosis of cervical dysplasia or carcinoma; instead, code the specific condition once confirmed.
• This code is for the finding on screening, not the screening procedure itself.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is related to the abnormal finding or follow-up.
