Code Description

ICD-10 O34.42 is a billable code used to indicate a diagnosis of maternal care for other abnormalities of cervix, second trimester.

Key Diagnostic Point:

O34.42 refers to maternal care for abnormalities of the cervix that may arise during the second trimester of pregnancy. These abnormalities can include cervical incompetence, cervical polyps, or other structural anomalies that may pose risks to the pregnancy. Maternal care in this context involves close monitoring and management strategies to mitigate potential complications such as preterm labor or delivery. Women with a history of cervical surgery, such as conization or LEEP procedures, may be at increased risk for these abnormalities. Additionally, previous cesarean deliveries can lead to uterine scarring, which may complicate the assessment of cervical integrity. Care providers must ensure thorough documentation of the patient's obstetric history, including any previous interventions, to guide management and inform decisions regarding the mode of delivery. Regular ultrasounds and cervical length assessments are often employed to monitor the condition of the cervix and to determine the need for interventions such as cervical cerclage, which may be indicated in cases of cervical incompetence.

  • Differentiation between normal and abnormal cervical findings
  • Potential for multiple concurrent obstetric conditions

Audit Risk Factors

  • Inadequate documentation of cervical assessments
  • Failure to note previous obstetric history
  • Misclassification of cervical abnormalities
  • Lack of follow-up documentation for monitoring

Frequently Asked Questions

What are the implications of coding O34.42 for a patient with a history of cervical surgery?

Coding O34.42 for a patient with a history of cervical surgery indicates that the provider is monitoring for potential complications related to cervical integrity. It is crucial to document the patient's surgical history and any current findings to ensure appropriate management and coding accuracy.
