Code Description

ICD-10 O24.011 is a billable code used to indicate a diagnosis of pre-existing type 1 diabetes mellitus, in pregnancy, first trimester.

Key Diagnostic Point:

Pre-existing type 1 diabetes mellitus in pregnancy poses significant risks to both the mother and fetus, particularly during the first trimester when organogenesis occurs. Women with type 1 diabetes must maintain strict glycemic control to minimize the risk of congenital anomalies, miscarriage, and other complications. Insulin management is crucial, as these patients may require adjustments in their insulin regimen due to hormonal changes that affect insulin sensitivity. Regular monitoring of blood glucose levels is essential, and healthcare providers often recommend continuous glucose monitoring (CGM) for better management. Fetal monitoring is also critical, as it helps assess fetal well-being and detect any potential complications early. The first trimester is a vital period for establishing a care plan that includes dietary modifications, exercise, and frequent consultations with a multidisciplinary team, including obstetricians, endocrinologists, and dietitians.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Need for precise documentation of diabetes management and insulin therapy.
  • Variability in glycemic control and its impact on pregnancy outcomes.
  • Potential for multiple comorbidities requiring additional coding.
  • Involvement of a multidisciplinary care team complicating documentation.

Audit Risk Factors

  • Inadequate documentation of blood glucose levels and insulin adjustments.
  • Failure to document the multidisciplinary approach to care.
  • Omission of complications related to diabetes management.
  • Incorrect coding of diabetes type or gestational status.

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Documentation must include detailed accounts of diabetes management, including insulin types, dosages, and frequency of monitoring.

Common Clinical Scenarios

Management of diabetes during routine prenatal visits, adjustments in insulin therapy, and monitoring for complications.

Billing Considerations

Consideration of the patient's pre-pregnancy health status and any complications arising from diabetes.

Maternal-Fetal Medicine

Documentation Requirements

High-risk pregnancy documentation must include comprehensive assessments of fetal growth and development, as well as maternal health.

Common Clinical Scenarios

High-risk consultations, ultrasound evaluations for fetal anomalies, and assessments of placental function.

Billing Considerations

Focus on the potential for congenital anomalies and the need for specialized monitoring.
