Code Description

ICD-10 O24.911 is a billable code used to indicate a diagnosis of unspecified diabetes mellitus in pregnancy, first trimester.

Key Diagnostic Point:

Unspecified diabetes mellitus in pregnancy during the first trimester refers to a condition where a pregnant woman exhibits symptoms of diabetes but does not have a specific type identified, such as gestational diabetes or pre-existing diabetes. This condition can lead to various complications for both the mother and fetus, including increased risk of hypertensive disorders, preterm birth, and fetal macrosomia. Management typically involves monitoring blood glucose levels, dietary modifications, and possibly insulin therapy. Close fetal monitoring is essential to assess the well-being of the fetus and to mitigate risks associated with maternal diabetes. The first trimester is a critical period for fetal development, making early diagnosis and management crucial to ensure positive outcomes for both mother and child.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in diabetes types and management protocols
  • Need for precise documentation of blood glucose levels
  • Differentiation between pre-existing and gestational diabetes
  • Potential for multiple comorbidities affecting pregnancy

Audit Risk Factors

  • Inadequate documentation of diabetes management
  • Failure to specify the type of diabetes
  • Lack of evidence for fetal monitoring
  • Inconsistent blood glucose level records

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Documentation must include detailed patient history, current management strategies, and any complications arising from diabetes.

Common Clinical Scenarios

A patient diagnosed with diabetes prior to pregnancy presenting for prenatal care, or a patient with newly diagnosed diabetes during the first trimester.

Billing Considerations

Accurate coding requires clear differentiation between types of diabetes and thorough documentation of treatment plans.

Maternal-Fetal Medicine

Documentation Requirements

High-risk pregnancy documentation must include comprehensive assessments of maternal and fetal health, including ultrasound findings and glucose monitoring.

Common Clinical Scenarios

Patients with a history of diabetes presenting for high-risk obstetric management or those requiring insulin therapy.

Billing Considerations

Special attention to fetal growth and development is necessary, along with detailed documentation of any interventions.
