Code Description

ICD-10 O33.1 is a billable code used to indicate a diagnosis of maternal care for disproportion due to generally contracted pelvis.

Key Diagnostic Point:

Maternal care for disproportion due to a generally contracted pelvis refers to the clinical scenario where the maternal pelvic dimensions are insufficient to allow for the passage of the fetus during delivery. This condition is often identified during prenatal assessments, where measurements of the pelvis may indicate a risk for cephalopelvic disproportion (CPD). CPD can lead to complications during labor, necessitating careful planning for delivery. In cases where the fetus is too large or the pelvis is too narrow, cesarean delivery may be indicated to ensure the safety of both the mother and the infant. Maternal care in this context involves close monitoring, potential referral to a maternal-fetal medicine specialist, and thorough documentation of the clinical findings and decision-making process regarding delivery methods. The management of this condition is crucial to prevent labor complications and ensure optimal outcomes for both mother and child.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in pelvic measurements and definitions of disproportion.
  • Need for accurate assessment of fetal size and position.
  • Potential for multiple delivery methods (vaginal vs. cesarean).
  • Documentation requirements for high-risk pregnancies.

Audit Risk Factors

  • Inadequate documentation of pelvic measurements.
  • Failure to document the rationale for cesarean delivery.
  • Misclassification of CPD versus other labor complications.
  • Lack of clear communication between providers regarding care plans.
