Maternal care for disproportion due to inlet contraction of pelvis

Code Description

ICD-10 O33.2 is a billable code used to indicate a diagnosis of maternal care for disproportion due to inlet contraction of pelvis.

Key Diagnostic Point:

Maternal care for disproportion due to inlet contraction of pelvis refers to a condition where the pelvic inlet is narrowed, leading to a mismatch between the size of the fetus and the dimensions of the maternal pelvis. This condition can result in cephalopelvic disproportion (CPD), where the fetal head cannot engage properly in the pelvis, potentially complicating labor and delivery. Inlet contraction can be due to various factors, including congenital pelvic deformities, previous pelvic surgeries, or conditions affecting pelvic structure. Management often involves careful monitoring of the pregnancy, assessment of fetal size, and planning for delivery, which may include cesarean section if vaginal delivery is deemed unsafe. The condition requires a multidisciplinary approach, including obstetricians and maternal-fetal medicine specialists, to ensure optimal outcomes for both mother and baby.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in pelvic anatomy and its impact on delivery options
  • Need for precise documentation of pelvic measurements
  • Differentiation between types of disproportion (e.g., inlet vs. outlet)
  • Potential for multiple coding scenarios based on delivery method

Audit Risk Factors

  • Inadequate documentation of pelvic measurements
  • Failure to document clinical rationale for cesarean delivery
  • Misclassification of type of disproportion
  • Lack of clear communication regarding maternal and fetal health status

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Detailed documentation of pelvic assessments, fetal size, and labor progress is essential. Providers should note any previous surgeries or conditions affecting the pelvis.

Common Clinical Scenarios

Common scenarios include a patient presenting with CPD during labor, requiring assessment of the fetal head's engagement and potential cesarean delivery.

Billing Considerations

Accurate coding requires understanding the implications of inlet contraction on delivery options and maternal health.

Maternal-Fetal Medicine

Documentation Requirements

High-risk pregnancy documentation must include comprehensive assessments of maternal and fetal health, including imaging studies and consultations.

Common Clinical Scenarios

Complex maternal-fetal scenarios may involve multiple risk factors, necessitating a multidisciplinary approach to care.

Billing Considerations

Considerations for high-risk obstetric coding include the need for thorough documentation of all assessments and interventions.

Coding Guidelines

Inclusion Criteria

Use O33.2 When
  • Official coding guidelines for obstetrics emphasize the importance of accurate documentation of maternal conditions affecting delivery
  • Specific criteria for coding O33
  • 2 include clear evidence of inlet contraction and its impact on labor
