Code Description

ICD-10 O33.3 is a billable code used to indicate a diagnosis of maternal care for disproportion due to outlet contraction of pelvis.

Key Diagnostic Point:

Maternal care for disproportion due to outlet contraction of the pelvis refers to a condition where the dimensions of the pelvic outlet are insufficient to allow for the passage of the fetus during delivery. This condition can lead to cephalopelvic disproportion (CPD), where the fetal head is too large to fit through the maternal pelvis. It is crucial for healthcare providers to assess the pelvic dimensions during prenatal visits, especially in cases of suspected CPD. The management of this condition often involves careful planning for delivery, which may include the consideration of cesarean delivery to prevent complications for both the mother and the infant. Accurate diagnosis and coding are essential for appropriate care and reimbursement, as well as for tracking maternal and fetal outcomes. The condition may be identified through clinical examination, imaging studies, or during labor when the progress of labor is inadequate. Proper documentation of the maternal history, physical examination findings, and any imaging results is vital for coding this condition accurately.

Medium Complexity

Complexity Factors

  • Variability in pelvic anatomy among patients
  • Need for precise documentation of clinical findings
  • Differentiation between types of disproportion
  • Potential for multiple delivery methods (vaginal vs. cesarean)

Audit Risk Factors

  • Inadequate documentation of pelvic measurements
  • Failure to specify the type of disproportion
  • Lack of clear delivery planning notes
  • Misclassification of the delivery method

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of maternal conditions, improving the accuracy of data collection and reimbursement processes. O33.3 provides a clear distinction for cases of outlet contraction, which was less defined in ICD-9.
