Code Description

ICD-10 O24.112 is a billable code used to indicate a diagnosis of pre-existing type 2 diabetes mellitus, in pregnancy, second trimester.

Key Diagnostic Point:

Pre-existing type 2 diabetes mellitus in pregnancy poses unique challenges for both maternal and fetal health. During the second trimester, the physiological changes in a pregnant woman can significantly affect glucose metabolism. Insulin resistance typically increases, necessitating careful monitoring and management of blood glucose levels. Women with pre-existing type 2 diabetes are at higher risk for complications such as preeclampsia, macrosomia, and neonatal hypoglycemia. Regular fetal monitoring is essential to assess fetal growth and well-being, often involving ultrasound assessments and non-stress tests. Management may include dietary modifications, blood glucose monitoring, and insulin therapy adjustments to maintain optimal glycemic control. Close collaboration among obstetricians, endocrinologists, and dietitians is crucial to ensure the health of both mother and baby throughout the pregnancy.

Complexity Factors

  • Need for precise documentation of diabetes management and insulin therapy.
  • Variability in treatment protocols based on individual patient needs.
  • Potential for multiple comorbidities affecting pregnancy outcomes.
  • Increased risk of complications requiring additional monitoring and interventions.

Audit Risk Factors

  • Inadequate documentation of blood glucose levels and insulin management.
  • Failure to document the impact of diabetes on pregnancy outcomes.
  • Lack of interdisciplinary notes regarding patient management.
  • Inconsistent coding of complications related to diabetes.
