Code Description

ICD-10 O34.33 is a billable code used to indicate a diagnosis of maternal care for cervical incompetence, third trimester.

Key Diagnostic Point:

Cervical incompetence, also known as cervical insufficiency, is a condition where the cervix begins to dilate and efface prematurely, often leading to preterm birth or pregnancy loss. In the third trimester, maternal care for cervical incompetence is critical as it poses significant risks to both the mother and fetus. This condition may be associated with abnormalities of the pelvic organs, such as uterine anomalies or previous cervical surgeries, including cone biopsies or LEEP procedures, which can weaken cervical integrity. Additionally, a history of cesarean deliveries may contribute to uterine scarring, further complicating the pregnancy. Management often involves close monitoring, potential cervical cerclage placement, and patient education regarding signs of preterm labor. Accurate coding for cervical incompetence requires thorough documentation of the patient's obstetric history, including any previous interventions and current pregnancy complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for detailed obstetric history including previous surgeries.
  • Differentiation between cervical incompetence and other causes of preterm labor.
  • Documentation of any interventions such as cervical cerclage.
  • Understanding of associated conditions like uterine scarring from previous cesareans.

Audit Risk Factors

  • Inadequate documentation of cervical assessments.
  • Failure to document previous obstetric history accurately.
  • Misclassification of cervical incompetence versus other obstetric conditions.
  • Lack of clarity on the management plan and interventions performed.
