Code Description

ICD-10 O24.9 is a billable code used to indicate a diagnosis of unspecified diabetes mellitus in pregnancy, childbirth and the puerperium.

Key Diagnostic Point:

Unspecified diabetes mellitus in pregnancy, childbirth, and the puerperium refers to a condition where a pregnant woman has diabetes that is not clearly defined as either pre-existing or gestational diabetes. This condition can complicate pregnancy and may require careful management to ensure the health of both the mother and the fetus. Diabetes in pregnancy can lead to various complications, including macrosomia, preeclampsia, and increased risk of cesarean delivery. Insulin management is often necessary to maintain blood glucose levels within a target range, and fetal monitoring is crucial to assess fetal well-being and growth. Regular screening for gestational diabetes is recommended, especially for women with risk factors such as obesity, family history of diabetes, or previous gestational diabetes. The management of diabetes during pregnancy involves a multidisciplinary approach, including obstetricians, endocrinologists, and dietitians, to optimize maternal and fetal outcomes.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between pre-existing and gestational diabetes
  • Variability in insulin management protocols
  • Need for comprehensive fetal monitoring
  • Potential for multiple comorbidities

Audit Risk Factors

  • Inadequate documentation of diabetes type
  • Failure to document insulin management
  • Lack of fetal monitoring records
  • Inconsistent coding of related conditions

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Documentation must include details of diabetes management, maternal health status, and fetal monitoring results.

Common Clinical Scenarios

A pregnant woman diagnosed with diabetes during routine screening requiring insulin therapy and regular fetal assessments.

Billing Considerations

Accurate coding requires clear documentation of the diabetes type and management plan.

Maternal-Fetal Medicine

Documentation Requirements

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

Common Clinical Scenarios

A high-risk pregnancy with a history of diabetes requiring specialized care and monitoring.

Billing Considerations

Consideration of potential complications and the need for a multidisciplinary approach to care.
